Handling the same click event in a nested control inside ListBoxItem DataTemplate - WPF
|
<p>When we have a custom listbox with a defined event-handling for the left-click of the mouse, and also an additional shape inside the ListBoxItem data template which needs to do some action when it is clicked how can we handle these </p>
<p>I have a Custom ListBox witch tries to handle the Click event :</p>
<p><strong>In the ContentView:</strong></p>
<pre><code> <ABC:AListBox
ClickCommand="{Binding LaunchCommand}"
...>
</ABC:AListBox>
</code></pre>
<p><strong>In it's datatemplate we have this:</strong></p>
<pre><code> <DataTemplate x:Key="ThisListTemplate">
<StackPanel ...>
<Border Grid.Column="1" VerticalAlignment="Center">
<TextBlock
FontSize="15"
Foreground="White"
Text="{Binding Path=ItemTitle}" />
</Border>
<Canvas Height ="12" Width ="12" >
<Ellipse Name = "TheEllipse" Stroke="Black" Height ="12"
Width ="12" Cursor="Hand" Canvas.Left="185" Canvas.Top="12">
</Ellipse>
<Ellipse.InputBindings>
<MouseBinding Gesture="LeftClick"
Command="{Binding DataContext.LaunchFromXamlCommand , RelativeSource={RelativeSource AncestorType=ABC:AListBox}}"
CommandParameter="{Binding}" />
</Ellipse.InputBindings>
</Canvas>
</StackPanel>
</DataTemplate>
</code></pre>
<p><strong>And in the MVVM as our data context we have:</strong></p>
<pre><code> public ICommand LaunchCommand { get; private set; }
public DelegateCommand<object> LaunchFromXamlCommand { get; private set; }
// Initialization on load:
this.LaunchCommand = new DelegateCommand(this.LaunchRun);
this.LaunchFromXamlCommand = new DelegateCommand<object>(this.LaunchFromXamlRun);
//---------
private void LaunchFromXamlRun(object param)
{
TheListItem app = (TheListItem)param;
...
}
private void LaunchRun()
{ ... }
</code></pre>
<p>Here I used 2 different commands LaunchCommand as an ICommand in addition with LaunchFromXamlCommand which is called via the template.</p>
<p>The <code>LaunchFromXamlRun</code> will get triggered fine and as expected.
But also as it can be guessed there will be 2 raised events and 2 commands getting triggered which I want to omit one and ignore the general ListBox event handler when that shape is get hit.</p>
<p>What can be the best solution for doing this?</p>
<p><strong>FYI:</strong> <em>(Maybe not so important just for a note)</em> The App is using earlier versions of Prism (don't think that matters here) and has a modular code, everything is separated in different assemblies and the code is using MVVM pattern.</p>
<p>I wish we had something like <code>e.handled = true</code> in a mechanism that could be used in the given scenario.</p>

How to handle symbol not found compile error in java?

Route in Dash without creating inefficient, hidden items
|
<p>I am inheriting a plotly Dash app which currently has an <code>app.layout</code> as follows:</p>
<pre class="lang-py prettyprint-override"><code>def serve_layout():
return html.Div(
className="app",
children=[
dcc.Location(id="url", refresh=False),
build_navbar(),
html.Div(
id="app-container",
className="main-content",
children=[
dcc.Store(id="usecase-store", storage_type="session", data=LiveGraph.use_case_library),
dcc.Store(id="gen-config-store", storage_type="session", data=LiveGraph.gen_config),
dcc.Store(id="control-config-store", storage_type="session", data=LiveGraph.control_config),
dcc.Store(id="data-config-store", storage_type="session", data=LiveGraph.data_config),
dcc.Store(id="data-store", storage_type="session"),
dcc.Store(id="liveplot-store", storage_type="session"),
build_settings_tab(),
build_simulation_tab(),
build_network_tab(),
dcc.Interval(id='graph-update', interval=1000, max_intervals=1000, n_intervals=0,
disabled=True)
],
),
],
)
</code></pre>
<p>where there are 3 separate routes for each of the <code>build_*</code> functions; with a callback setting <code>{display: none}</code> on the <code>div</code>s returned by the non-selected functions. I propose the following code:</p>
<pre class="lang-py prettyprint-override"><code>def serve_layout():
return html.Div(
className="app",
children=[
dcc.Location(id="url", refresh=False),
build_navbar(),
html.Div(
id="app-container",
className="main-content",
children=[
dcc.Store(id="usecase-store", storage_type="session", data=LiveGraph.use_case_library),
dcc.Store(id="gen-config-store", storage_type="session", data=LiveGraph.gen_config),
dcc.Store(id="control-config-store", storage_type="session", data=LiveGraph.control_config),
dcc.Store(id="data-config-store", storage_type="session", data=LiveGraph.data_config),
dcc.Store(id="data-store", storage_type="session"),
dcc.Store(id="liveplot-store", storage_type="session"),
dcc.Interval(id='graph-update', interval=1000, max_intervals=1000, n_intervals=0,
disabled=True),
html.Div(id="main-content")
],
),
],
)
@app.callback(Output("main-content", "children"), [Input("url", "pathname")])
def route(path):
if path == "/":
return build_settings_tab()
# ...only return the individual function necessary for the path
</code></pre>
<p>Note that I have removed the three function calls from <code>serve_layout()</code> and added a <code>div#main-content</code>. The issue I'm running into is that I have callbacks set up to watch various inputs across the three pages, so I get an <code>Error loading dependencies</code> if I try to use the second code block. Is there a way around this, or do I really have to put <em>everything</em> in <code>app.layout</code> that I want to access later on? This would be really inefficient, as one of my pages creates charts and I don't want to render the charts and then set <code>{display: none}</code>, seems backwards and certainly sets off a lot of warning bells in my head... Are there any other solutions?</p>

Flutter: Stream not retrieving data from sub collection
|
<p>I am creating my own comment system.
I am using firebase to store the comments and then the replies into a subcollection.
My code is retrieving the main comments, but for some reason I can't get the sub comments.
Have double checked the path and everything.</p>
<p>My stream looks like this</p>
<pre><code> var retVal;
try {
retVal = FirebaseFirestore.instance
.collection('Challenges')
.doc(challenge.id)
.collection('comments')
.doc(comment.id)
.collection('SubComments')
.orderBy(CommentField.createdTime, descending: true)
.snapshots()
.transform(Utils.transformer<Comment>(Comment.fromJson));
return retVal;
} on FirebaseException catch (e)
{
print(e.toString());
return retVal;
}
}
</code></pre>
<p>(mind the var and other weird stuff. Was trying to see if i can catch a error, but no luck)</p>
<p>Code where I call the stream using Riverpod.</p>
<pre><code>final challengeSubCommentStreamProvider =
StreamProvider.autoDispose.family<List<Comment>, ReadSubCommentClass>((ref, parameters) {
final database = ref.watch(databaseProvider);
return database.readSubComments(parameters.challenge, parameters.comment);
});
return Consumer(
builder: (context, ScopedReader watch, child){
final userDataProvider = watch(userProvider);
final user = userDataProvider.user;
final ReadSubCommentClass parameters = ReadSubCommentClass(challenge: widget.challenge, comment: widget.comment!);
final challengeSubCommentStream = watch(challengeSubCommentStreamProvider(parameters));
return challengeSubCommentStream.when(
data: (comments) {
if(comments.isNotEmpty)
return SliverList(
delegate: SliverChildBuilderDelegate(
(context, int index){
return buildReplyCommentListTile(comments[index], user);
},
childCount: comments.length,
),
);
else return Container(color: Colors.blue,);
},
loading: () => SliverToBoxAdapter(child: Center(child: Text('Loading'),)),
error: (_,__) => SliverToBoxAdapter(child: Container()));
},
);
</code></pre>
<p>Picture from Firestore to depict path

<p><a href="https://i.stack.imgur.com/w7jpP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/w7jpP.png" alt="enter image description here" /></a>
The code is just stuck at Loading and not getting any values.</p>

Best way to chain @Exceptionhandler from PUT method Handler?
|
<p>I'm implementing Exception handling.</p>
<p>The PUT controller method is,</p>
<pre class="lang-java prettyprint-override"><code>// ReservationApiController.java
@RestController
@RequestMapping(UriInfo.API_RESERVATION)
@Validated
public class ReservationApiController {
@PutMapping(UriInfo.API_RESERVATION_CANCEL)
public ReservationResponse removeReservations(
@PathVariable @Positive int reservationInfoId) {
if (!reservationInfoService.isReservationInfo(reservationInfoId)) {
throw new ResourceNotFoundException("No reservationInfo with the id is found.");
}
return reservationInfoService.cancel(reservationInfoId);
}
...
</code></pre>
<p>and there is the current code. What I want to do is 400 Bad response,</p>
<pre class="lang-java prettyprint-override"><code>// GlobalExceptionHandler.java
@ControllerAdvice
public class GlobalExceptionController {
@ResponseStatus(HttpStatus.BAD_REQUEST)
@ExceptionHandler({ ConstraintViolationException.class, ... })
public ModelAndView handleDisplayInfoNotFound(Exception e) {
logger.error("data is not valid.", e);
ModelAndView mav = new ModelAndView();
mav.setViewName("error");
mav.addObject("msg", "์ ํจํ์ง ์์ ์์ฒญ์

return mav;
}
</code></pre>
<p>Putting a negative value in the path variable results in the following exception, the exception is what I expected.</p>

<h3>Problem</h3>
<p>Unlike what I wanted, Response code is <strong>405 with default tomcat error page</strong>. and there is an error msg like that: PUT method doesn't support JSP... (I can't attach it here because it is in korean language)</p>
<ol>
<li>How can I implement the exception handling I want?</li>
<li>Is it good to return a HTML format response from the Rest Controller? Or what form of answer would be good to return?</li>
</ol>
<p>Thank you for reading!</p>

Sort multi-bucket aggregation by source fields inside inner multi-bucket aggregation
|
<p><em><strong>TL;DR:</strong> Using an inner multi-bucket aggregation (<code>top_hits</code> with <code>size: 1</code>) inside an outer multi-bucket aggregation, is it possible to sort the buckets of the outer aggregation by the data in the inner buckets?</em></p>
<hr>
<p>I have the following index mappings</p>
<pre><code>{
"parent": {
"properties": {
"children": {
"type": "nested",
"properties": {
"child_id": { "type": "keyword" }
}
}
}
}
}
</code></pre>
<p>and each child (in data) has also the properties <code>last_modified: Date</code> and <code>other_property: String</code>.</p>
<p>I need to fetch a list of children (of all the parents but without the parents), but only the one with the latest <code>last_modified</code> per each <code>child_id</code>. Then I need to sort and paginate those results to return manageable amounts of data.</p>
<p>I'm able to get the data and paginate over it with a combination of <code>nested</code>, <code>terms</code>, <code>top_hits</code>, and <code>bucket_sort</code> aggregations (and also get the total count with <code>cardinality</code>)</p>
<pre><code>{
"query": {
"match_all": {}
},
"size": 0,
"aggs": {
"children": {
"nested": {
"path": "children"
},
"aggs": {
"totalCount": {
"cardinality": {
"field": "children.child_id"
}
},
"oneChildPerId": {
"terms": {
"field": "children.child_id",
"order": { "_term": "asc" },
"size": 1000000
},
"aggs": {
"lastModified": {
"top_hits": {
"_source": [
"children.other_property"
],
"sort": {
"children.last_modified": {
"order": "desc"
}
},
"size": 1
}
},
"paginate": {
"bucket_sort": {
"from": 36,
"size": 3
}
}
}
}
}
}
}
}
</code></pre>
<p>but after more than a solid day of going through the docs and experimenting, I seem to be no closer to figuring out, how to sort the buckets of my <code>oneChildPerId</code> aggregation by the <code>other_property</code> of that single child retrieved by <code>lastModified</code> aggregation.</p>
<p><strong>Is there a way to sort a multi-bucket aggregation by results in a nested multi-bucket aggregation?</strong></p>
<hr>
<p>What I've tried:</p>
<ul>
<li>I thought I could use <code>bucket_sort</code> for that too, but apparently its <code>sort</code> can only be used with paths containing other single-bucket aggregations and ending in a metic one.</li>
<li>I've tried to find a way to somehow transform the 1-result multi-bucket of <code>lastModified</code> into a single-bucket, but haven't found any.</li>
</ul>
<hr>
<p><em>I'm using ElasticSearch 6.8.6 (the <code>bucket_sort</code> and similar tools weren't available in ES 5.x and older).</em></p>

Getting back to a CSS position sticky element with JavaScript?
|
<p>I have a page where all sections fill the entire screen and are positioned with CSS <code>position: sticky;</code> in order to achieve a <em>layered</em> effect. See here:</p>
<p><a href="https://codesandbox.io/s/ecstatic-khayyam-cgql1?fontsize=14&hidenavigation=1&theme=dark" rel="nofollow noreferrer">https://codesandbox.io/s/ecstatic-khayyam-cgql1?fontsize=14&hidenavigation=1&theme=dark</a></p>
<p>This all works great and as expected.</p>
<p>The problem comes however from navigating between these areas with JavaScript. If you try using the menu, you can see that the links will work on sections that we haven't fully gotten to yet (and therefore not "sticky") but does not allow you to "go back up" the page.</p>
<p>I believe this is an issue with <code>el.getBoundingClientRect()</code> once an element has become "sticky", its top value becomes essentially always zero.</p>
<p>Here I am using a small library called <code>Jump.js</code> to jump around but even in vanilla JS this issue would still be the same, as the problem is a result of the calculation from when the element becomes sticky. </p>
<p>Is there any way to find the original position for each section before it was sticky? At least that way I could navigate the user by setting the scroll position manually.</p>
<p>I am using Vue.js but that does not affect the issue at hand which is CSS and JS related.</p>
<p><strong>App.vue</strong></p>
<pre><code><template>
<main id="app">
<ul class="menu">
<li @click="goTo('A')">Section A</li>
<li @click="goTo('B')">Section B</li>
<li @click="goTo('C')">Section C</li>
<li @click="goTo('D')">Section D</li>
<li @click="goTo('E')">Section E</li>
</ul>
<SectionItem id="A" color="red"/>
<SectionItem id="B" color="green"/>
<SectionItem id="C" color="blue"/>
<SectionItem id="D" color="orange"/>
<SectionItem id="E" color="purple"/>
</main>
</template>
<script>
import jump from "jump.js";
import SectionItem from "./components/SectionItem.vue";
export default {
name: "App",
components: {
SectionItem
},
methods: {
goTo(id) {
jump(`#${id}`, {
duration: 300
});
}
}
};
</script>
</code></pre>
<p><strong>SectionItem.vue</strong></p>
<pre><code><template>
<div :id="id" class="SectionItem" :style="styles">
<p>I am section item: {{ id }}</p>
</div>
</template>
<script>
export default {
name: "SectionItem",
props: {
id: {
type: String,
required: true
},
color: {
type: String,
required: true
}
},
computed: {
styles() {
return {
backgroundColor: this.color
};
}
}
};
</script>
<style>
.SectionItem {
position: sticky;
top: 0;
width: 100%;
min-height: 100vh;
padding: 20px;
color: white;
border: 10px solid white;
}
</style>
</code></pre>
<p>I'm looking for any reasonable solutions that get get the auto-scrolling to work in both directions. Many thanks for your time.</p>

Exception in thread "main" java.lang.IllegalStateException: Failed to transform class with name
|
<p>I am using JAVA 1.8 with the Javaassist version as 3.24.0 and power mock 1.7.4. I am facing this issue when I am including a class in @PrepareForTest.Here the MainClass class depends on serverCommunicator.class instance.</p>
<pre><code> public class MainClass
{
public void sendInitRequest()
{
ServerCommunicator communicator = ServerCommunicator.getInstance();
communicator.init();
}
}
public class ServerCommunicator
{
private static communicator ;
public static ServerCommunicator getInstance()
{
return communicator;
}
public void init()
{
System.out.println("Communication has initialized ");
}
}
</code></pre>
<p>Test case for the above method I have written like this:</p>
<pre><code>@PowerMockIgnore("javax.management.*")
@RunWith(PowerMockRunner.class)
@PrepareForTest({ ServerCommunicator.class }
@Test
public void testSendInitRequest() throws NullPointerException
{
try
{
MainClass mainClass = new MainClass();
final ServerCommunicator communicator = PowerMockito.mock(new ServerCommunicator());
PowerMockito.mockStatic(ServerCommunicator.class);
when(ServerCommunicator.getInstance()).thenReturn(communicator);
PowerMockito.doNothing().when(communicator).init();
mainClass.sendInitRequest();
assertTrue(true);
}
catch (Throwable t)
{
assertTrue(1 == 0);
}
}
</code></pre>
<p>So when I am adding the serverCommunicator.class in @PrepareForTest it is showing the below error.Exception in thread "main" java.lang.IllegalStateException: Failed to transform class with name ServerCommunicator. Reason: null</p>

<p>The problem is that it isn't running the MainMenu screen and as you can see I have some debugging code with numbers in the console, and it only outputs 3 and then 6, but nothing else. Can anybody tell me why it isn't loading my main menu screen or running anything else in the code? FYI I didn't write a lot of this, I got it from here: <a href="https://github.com/Matsemann/libgdx-loading-screen/tree/libgdx-1.4.1-Deathsbreed" rel="nofollow">https://github.com/Matsemann/libgdx-loading-screen/tree/libgdx-1.4.1-Deathsbreed</a></p>
<p>EDIT: I have all of my values in a file called Constants, and everything loads from there. If you need any more info, I will edit the OP.</p>
<p>Much Appreciated,</p>

Bootstrap contact form module issue
|
<p>I am having trouble with getting this code to not show a thank you modul for incomplete submissions. I also would like the page redirect to originating page(with a pop up modul for either confirmation or error on the page in a modul would be optimal) or just redirect to the originating page without having to create a new PHP file for every page a contact form is on. I have several.</p>
<p>The way it is now it can send mail but it directs to a blank white page with just type on it, and a request to use the browser back button to return to originating page. Also it fires the (Thank you)modul even if in put is in correct. would it please be possible to get help with this?</p>
<pre><code><form class="o-form" id="contactForm" action="php/contact.php" method="post">

How to add a dynamically generated file to my ear archive?
|
<p>Basically, we have an ear archive that has multiple dependencies. In those dependencies, we plan on filling the manifest or some properties file with multiple properties:</p>
<ul>
<li>build timestamp</li>
<li>buildnumber (from CI server)</li>
<li>groupId</li>
<li>artifactId</li>
<li>version</li>
</ul>
<p>This should already be possible for individual artifacts that are built by our CI server, and this is also not really the problem I'm having.</p>
<hr>
<p>Now I use maven for building my <strong>ear</strong> archive, with the maven-ear-plugin. My idea was to just use a groovy script (executed by gmaven-plus) that will read all the jar archives, and fetch the manifest. Then I can rewrite the manifest of the ear archive, or write my own properties file that contains the info I want.</p>
<pre><code>import org.apache.commons.io.FileUtils
import java.util.jar.JarFile
def path = "target/${project.name}-${project.version}"
def artifactDir = new File(path)
def output = new File("$path/META-INF/build-info.properties")
def lines = []
artifactDir.listFiles().each { file->
if (file.isFile() && (file.name.endsWith(".war") || file.name.endsWith(".jar"))) {
def jar = new JarFile(file)
def manifest = jar.manifest
println "processing: $file.name"
println manifest.mainAttributes
println jar.properties
manifest.mainAttributes.keySet().each { attrKey->
def val = manifest.mainAttributes.getValue(attrKey.toString())
lines << "$file.name.$attrKey=$val"
}
}
}
FileUtils.writeLines(output, lines as Collection<?>
</code></pre>
<p>)</p>
<p>This script works fine, and will write the <code>build-info.properties</code> file with all the info I'd like to be in there.</p>
<p>This is the plugin configuration:</p>
<pre><code><plugin>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<id>create-manifest</id>
<phase>package</phase>
<goals>
<goal>execute</goal>
</goals>
</execution>
</executions>
<configuration>
<scripts>
<script>file:///${project.basedir}/src/main/gmaven/create-manifest.groovy</script>
</scripts>
</configuration>
</plugin>
</code></pre>
<p>Of course, you'll already notice what's wrong with this: the <code>package</code>phase is too late, <code>prepare-package</code> is too early, because the ear plugin has not yet copied the dependencies I'm scanning.</p>
<hr>
<h2>Conclusion</h2>
<p>Well, the obvious thing to do would be to unzip the ear produced, and then add the file manually, then zip it again. But that seems pretty dirty to me, and I was wondering whether there is no cleaner way to do this?</p>
<p>Perhaps by leverageing gradle, or some option of the maven-ear-plugin I have not yet discovered? Or just in general, how would you tackle the specific problem I am facing here?</p>

Unexpected prints
|
<p>I am trying to make a little program which can register a word in Spanish (I am from Spain), the meaning in English and other thing which I have called "Complicado". "Complicado" is not relevant at this point of the program. I am really confused with the behavior of the code. I don't know why \n is not working how I thought it works. Furthermore some lines are getting printed before I would like.</p>
<p>The problem is in the if eleccion == 2.
For instance, when eleccion is equal to 2 I expected the prints would be:</p>
<pre><code>Empieza el test...
Pregunta nรบmero 1
Empieza el test...Indica el equivalente castellano de la palabra: Hello (Or the other possibility)
</code></pre>
<p>But this is a capture of my console:<br />
<a href="https://i.stack.imgur.com/vDOAB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vDOAB.png" alt="Capture of my console" /></a></p>
<p>I attached below the code.
I appreciate all the help possible</p>
<pre><code>import json
import random
eleccion = input("ยฟAรฑadir palabras?. (1)\nยฟTest?. (2)\nLista. (3)\n")

<p>One example of what could be in ingles.json is:</p>

Why does my avro schema not work for this dataset?
|
<p>I am using streamsets to get data from an API. The data is in XML format. I need to convert it to parquet in the end but there is a middle stage which requires xml to avro conversion first.</p>
<p>Below is the data that I get in streamsets -</p>
<pre><code>XMLData : MAP
Metadata : LIST [ 20 ]
LevelCounts : LIST [ 1 ]
Record : LIST [ 46 ]
attrcount : STRING
</code></pre>
<p>Expanding the metadata would give a list where each element in the list has 4 key value pairs -</p>
<pre><code> attr|name : STRING
attr|guid : STRING
attr|alias : STRING
attr|id : STRING
</code></pre>
<p>Similary each record in the LevelCounts and Record is made up of a set of key value pairs. Record/Field is similar to the metadata.</p>
<pre><code> attr|levelId : STRING
attr|contentId : STRING
attr|moduleId : STRING
attr|parentId : STRING
attr|levelGuid : STRING
Field : LIST [ 20 ]
</code></pre>
<p>I need help understanding why my Avro schema is wrong and what should be the correct one. I get an empty file with the schema in it.</p>
<p>Below is the avro schema I am using</p>
<pre><code>{
"type": "record",
"name": "XMLData",

Python - Returning query result from server to client in Flask
|
<ul>
<li><p><strong>What I have</strong></p>
<p>I have a Client/Server in Flask. The client sends a query in JSON format to the server and the server creates a JSON file. There is another tool which takes this query, executes it on a db and writes the result to a results.txt file. The server periodically checks the 'results' directory for .txt files and if it finds a new file it extracts the result. For the periodic checking part I used APS.</p>
</li>
<li><p><strong>What I want to do</strong>
Now I want to send this data (queryResult) which the server has extracted from the .txt file back to the client.</p>
</li>
</ul>
<p>This is what I have done so far.</p>
<ul>
<li><strong>Server Code:</strong></li>
</ul>
<blockquote>
<pre><code>app = Flask(__name__)
api = Api(app)
# Variable to store the result file count in the Tool directory
fileCount = 0
# Variable to store the query result generated by the Tool
queryResult = 0
# Method to read .txt files generated by the Tool
def readFile():
global fileCount
global queryResult
# Path where .txt files are created by the Tool
path = "<path>"
tempFileCount = len(fnmatch.filter(os.listdir(path), '*.txt'))
if (fileCount != tempFileCount):
fileCount = tempFileCount
list_of_files = glob.iglob(path + '*.txt')
latest_file = max(list_of_files, key=os.path.getctime)
print("\nLast modified file: " + latest_file)
with open(latest_file, "r") as myfile:
queryResult = myfile.readlines()
print(queryResult) # I would like to return this queryResult to the client

<p>Can anyone please help me as to how to send this queryResult back to the Client?</p>
<p>EDIT: I would like the server to send the queryResult back to the client each time it encounters a new file in the Tool directory i.e., every time it finds a new file, it extracts the result (which it is doing currently) and send it back to the client.</p>

Can I use an if statement to display the changes in my array (JavaScript)?
|
<p>I'm trying to make my function <code>displayValues()</code> display each value stored in the array <code>arrValues</code> each time it is called. The array undergoes a change before the second time it is called.</p>
<p>I am having trouble making the output <code>text</code> display the starting values in one
HTML element, and then the updated values in the second element. I am not allowed to have the functions return any value. At the moment my If statement only shows the updated array. I'd like to know what's causing the <code>before</code> element to not be shown?</p>

Bootstrap switch doesn't work on localhost and Chrome
|
<p>I've got weird problem with Chrome browser that I use for development purposes. I've created dashboard with <a href="https://github.com/nostalgiaz/bootstrap-switch" rel="nofollow noreferrer">Bootstrap Switch plugin</a> and everything was fine till another system reboot. For some reason, that one plugin stopped styling properly.</p>
<p><a href="https://i.stack.imgur.com/A85tI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/A85tI.png" alt="styling error"></a></p>
<p>No errors in dev console.</p>
<p>I thought it was related to cache (reloaded page, reloaded without cache, cleared cache) - nothing. </p>
<p>Checked with IE and... it works OK. </p>
<p>Suspecting cache to be the problem, I've changed the folder where I keep the website. Still nothing. </p>
<p>All Chrome addons disabled - nothing.</p>
<p>Next thought was some kind of collision with other scripts, so I removed one after another until I was left with whatever is required to run that plugin - and still nothing! </p>
<p>I tried with Firefox and it works okay.</p>
<p>I accessed the website I got already deployed on server, where it was still working and the plugin ran okay. But when I downloaded it to localhost - the problem reappeared.</p>
<p>Finally I've discovered, that whenever I access my website locally using <a href="http://localhost" rel="nofollow noreferrer">http://localhost</a> - it somewhat crashes the styles. Changing to <a href="http://127.0.0.1" rel="nofollow noreferrer">http://127.0.0.1</a> fixed the problem - or rather appeared to be a workaround.</p>

<p>Each data set has a unique datetime value (<code>Trigger Time</code>) that is treated as a comment. Each data set also has a <code>Time</code> variable indicating the time that has passed since the datetime in <code>Trigger Time</code>. What I want to do is calculate the datetime for each observation so that I can graph the data as a time series using <strong>R</strong> Statistics. Is there a way to accomplish this? Merging the datasets and appending the comments does not necessarily have to be done in <strong>R</strong>. </p>
<p>I have imported the data from all files in <strong>R</strong> Statistics using the <code>list.files</code> and <code>llply</code> functions, <a href="http://econometricsense.blogspot.no/2011/01/merging-multiple-data-frames-in-r.html" rel="nofollow noreferrer">as suggested by Matt Bogard in this blog post</a>. Here is a <a href="https://dl.dropboxusercontent.com/u/616262/data-test.zip" rel="nofollow noreferrer">link</a> to the data sets I use in the example below. </p>
<pre><code>require(plyr)
filenames <- list.files(path = "C:/Users/bys/Desktop/log-trykk-vinkelrett/data-test/", full.names = TRUE)
import.list <- llply(filenames, read.csv)
</code></pre>
<p>Here is a <a href="https://dl.dropboxusercontent.com/u/616262/importlist.txt" rel="nofollow noreferrer">link the output from <code>import.list</code></a> using <code>dput</code>.</p>
<p>I think I then need to do something similar to what <a href="https://stackoverflow.com/questions/1562124/merge-many-data-frames-from-csv-files">learnr is suggesting here</a>, but so far my attempts at extracting <code>Trigger Time</code> and adding a new variable with <code>Trigger Time</code> for each observation have been unsuccessful.</p>
<p>Solving the problem with Open Refine causes the program to crash every time I try to load all the data sets. <strong>R</strong> may not be the best tool for processing text files, but I don't have any experience with Python, Ruby or similar languages. </p>

Android Fragment Interface Unresponsive
|
<p>I am having a strange issue with my program that I cannot explain and I have thus far not been able to find a solution. I have a simple activity that will switch between fragments and run the user through an initial setup of the app. The first fragment is just a text view at the top, with a button on the bottom with an onClickListener set to call a method on the parent activity, however in testing, when I click on the button, nothing happens. It does not change color like a normal button would, and no click seems to be registered.</p>
<p>Here is the XML for the layout:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:text="@string/setup_intro" />
<Button
android:id="@+id/next_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:clickable="true"
android:width="72dp"
android:text="@string/next_button" />
</RelativeLayout>
</code></pre>
<p>And this is the fragment code where I implement the onClickListener</p>
<pre><code>public class SetupFragmentInitialScreen extends SherlockFragment
{
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState)
{
View parentView = null;
parentView = inflater.inflate(R.layout.setup_fragment_initial_screen,
container,
false);
Button nextButton = (Button)parentView.findViewById(R.id.next_button);
nextButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
Log.v("ButtonPressed", "You Pressed the button!");
((InitialActivity)getActivity()).onInitialScreenNextPress();
}
});
return parentView;
}
}
</code></pre>
<p>And lastly, here is my code for my activity so far</p>
<pre><code>public class InitialActivity extends SherlockFragmentActivity
{
private SetupFragmentInitialScreen initialScreen;
private SetupFragmentPreferenceOneScreen preferenceOneScreen;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
initialScreen = new SetupFragmentInitialScreen();
preferenceOneScreen = new SetupFragmentPreferenceOneScreen();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
fragmentTransaction.replace(android.R.id.content,
initialScreen);
fragmentTransaction.commit();
}
public void onInitialScreenNextPress()
{
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
android.R.anim.fade_out);
fragmentTransaction.replace(android.R.id.content,
preferenceOneScreen);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
}
</code></pre>
<p>So far the code to me seems correct, but as I said, there is no reaction from the interface when I try to press the button.</p>
<p>Edit: I have added the following code to my Activity to check for touch events</p>
<pre><code>@Override
public boolean onTouchEvent(MotionEvent event)
{
super.onTouchEvent(event);
Log.v("Touch Detected", "You are touching the screen.");
return false;
}
</code></pre>
<p>It logs events all over the screen, except for when I'm touching the button, so the activity is receiving touch events, but the UI itself is not. I also tried loading another interface which has a pair of radio buttons, and they too were unresponsive. Is there something I'm doing wrong with initializing the fragments?</p>

</blockquote>
<p>I would be very happy for any help - thanks a lot in advance !
Elain</p>
<p>Here are my python/proto modules - to reproduce the error:</p>
<p>I have a django (4.0.3) model with a JSON field:</p>
<pre><code># models.py
class Data(models.Model):
data_id = models.AutoField(primary_key=True)
data_JSON = models.JSONField(blank=True, null=True, help_text="JSON representation of the data")
</code></pre>
<p>My serializer.py looks like this:</p>
<pre><code>from my_data.models import Data
from django_grpc_framework import proto_serializers
from rest_framework import serializers
import my_data.my_data_pb2
class DataProtoSerializer(proto_serializers.ModelProtoSerializer):
class Meta:
model = Data
proto_class = my_data.my_data_pb2.Data
fields = ['data_id', 'data_JSON']
</code></pre>
<p>The auto generated protofile file (I used the django framework proto generator) my_data.proto:</p>
<pre><code>
syntax = "proto3";
package my_data;
import "google/protobuf/empty.proto";
service DataController {
rpc List(DataListRequest) returns (stream Data) {}
rpc Create(Data) returns (Data) {}
rpc Retrieve(DataRetrieveRequest) returns (Data) {}
rpc Update(Data) returns (Data) {}
rpc Destroy(Data) returns (google.protobuf.Empty) {}
}
message Data {
int32 data_id = 1;
string data_JSON = 2;
}
message DataListRequest {
}
message DataRetrieveRequest {
int32 data_id = 1;
}
</code></pre>
<p>My service description - services.py :</p>
<pre><code>
from my_data.models import Data
from django_grpc_framework import generics
from my_data.serializers import DataProtoSerializer
class DataService(generics.ModelService):
"""
gRPC service that allows users to be retrieved or updated.
"""
queryset = Data.objects.all().order_by('data_id')
serializer_class = DataProtoSerializer
</code></pre>
<p>And finally the client: data_grpc_client.py:</p>
<pre><code>
import grpc
import my_data.my_data_pb2
import my_data.my_data_pb2_grpc
with grpc.insecure_channel('localhost:50051') as channel:
stub = my_data.my_data_pb2_grpc.DataControllerStub(channel)
for datum in stub.List(my_data.my_data_pb2.DataRequest()):
print("datum:",datum.name, end='')

Appearance customized segmentcontrol odd behavior
|
<p>I have a <code>UISegmentedControl</code> with a customized appearance, and I believe I have all of the necessary assets to have the correct appearance, and in most cases the appearance is as desired, however when I tap on one of the segments, before releasing, the edges of the segment, right about where the divider image is supposed to be, the appearance suddenly becomes incorrect. Attached are some screenshots, and here is my code for setting the different images:</p>
<pre><code> UIImage *segmentUnselectedBG = [[UIImage imageNamed:@"SegmentUnselectedBG"] resizableImageWithCapInsets:UIEdgeInsetsMake(3, 3, 3, 3)];
UIImage *segmentSelectedBG = [[UIImage imageNamed:@"SegmentSelectedBG"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 4, 4)];
UIImage *segmentDividerNoSelect = [[UIImage imageNamed:@"SegmentDividerNoSelect"] resizableImageWithCapInsets:UIEdgeInsetsMake(3, 3, 3, 3)];
UIImage *segmentDividerLeftSelect = [[UIImage imageNamed:@"SegmentDividerLeftSelect"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 4, 3)];
UIImage *segmentDividerRightSelect = [[UIImage imageNamed:@"SegmentDividerRightSelect"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 3, 4, 4)];
UIImage *segmentDividerBothSelect = [[UIImage imageNamed:@"SegmentDividerBothSelect"] resizableImageWithCapInsets:UIEdgeInsetsMake(4, 4, 4, 4)];
[self.programControlsSegment setBackgroundImage:segmentUnselectedBG forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[self.programControlsSegment setBackgroundImage:segmentSelectedBG forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
[self.programControlsSegment setDividerImage:segmentDividerNoSelect forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[self.programControlsSegment setDividerImage:segmentDividerLeftSelect forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[self.programControlsSegment setDividerImage:segmentDividerRightSelect forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
[self.programControlsSegment setDividerImage:segmentDividerBothSelect forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
</code></pre>
<p>Neither segment selected, appearance is correct:</p>
<p><img src="https://i.stack.imgur.com/WVbc9.png" alt="Neither selected - Correct"></p>
<p>Left Segment selected, appearance is correct:</p>
<p><img src="https://i.stack.imgur.com/ATbos.png" alt="Left selected - Correct"></p>
<p>Left segment selected, and user pressing on the left segment, appearance is incorrect</p>
<p><img src="https://i.stack.imgur.com/2Ff2v.png" alt="Left selected and highlighted - Incorrect"></p>
<p>Left segment selected, and user pressing on right segment, appearance is incorrect</p>
<p><img src="https://i.stack.imgur.com/1vHSg.png" alt="Left selected, right highlighted - Incorrect"></p>
<p>Right segment is selected, and user is pressing on left segment, appearance is incorrect</p>
<p><img src="https://i.stack.imgur.com/jZVCw.png" alt="Left highlighted, right selected - Incorrect"></p>
<p>Are there other segment states that I should be setting the divider image for?</p>
<p>EDIT:</p>
<p>This issue seems to be isolated to behavior only in iOS 7. Prior to this version, there did not seem to be a different state for the segments for when the user is actively pressing down on the segment</p>

Question about maven
|
<p>I read some useful posts here on SO about previous maven questions, I'm currently very interested in learning maven(cause I like it and because my boss requires me to). I'm currently reading [this][1] book and I'm working my way trough examples. Its a straightforward book but its has some errors inside(trivial ones), yet for a newbie like me can be hard to spot, once spotted it can be easily fixed. Is there any other book better to understand maven from top to bottom?</p>
<p>Second part of the question is relating an example in this book, maybe a simple explanations would resolve my doubts. </p>
<p>Here is the thing, I made a <code>simple-weather</code> project in java which retrieves the weather conditions from yahoo weather server, given the particular zip code it returns weather information. </p>
<p>Then I made an 'simple-webapp'(with maven as well as the one above I forgot to mention that), which is basicaly a web project which has some default servlet already there with maven and it does nothing.</p>
<p>And I have some <code>parent-project</code> I wanna merge those two projects into one, so I made a pom.xml which has 2 modules , 1 to retrieve info(java project) and other to display it on the web (web app). </p>
<p>I made everything work at the end, but here is the odd thing .. if I make webapp display any string "name" lets say then build it independently, it does exactly print that string. But when I put the webapp in the "parent-project" and change this string to "name1" and build it as sa partent-project sub module.. nothing changes ..</p>
<p>So I go back to the point, because simple-webapp is dependent on simple-weather I can't build it anymore on its own, so now if I wanna make some changes to the webapp.. modify the webapp outside the "parent-project" build it there then paste it back to the parent-project and then the changes will apply, why is that, why can't I directly change the servlet content/or add another one in the webapp as the part of the "parent-project"?</p>
<p>Thank you.. I know its a long and boring question, but I'm just trying to learn things and there is no better place to ask than here :D</p>

Deleting image problem with unlink function

Having an issue with modularization, can't get my program to run correctly
|
<p>I am creating a histogram which shows me the word and the frequency of each word within a text file.</p>
<p>I went through my previous code which worked and attempted to make it modular. This was practice for class, as we will be creating a Tweet Generator in the future.
Somewhere I am doing something wrong, but I can't see what it is for the life of me.</p>
<p>I were to create from the plain-text file:</p>

Split density plot in 4 groups and add the groups to data table
|
<p>I'm creating a density plot with <code>ggplot()</code> in <code>R</code>, where I specify the <code>median</code>, <code>5%</code> and <code>95%</code> quantiles with a vertical line (<code>geom_vline()</code>). Here is my plot construction:</p>
<pre><code>probs <- c(0.05, 0.95)
quantiles <- quantile(dt.all2018$Qeff, prob = probs)
q5 <- as.numeric(quantiles[1])
q95 <- as.numeric(quantiles[2])
median <- median(dt.all2018$Qeff)
p <- (ggplot(dt.all2018) +
geom_density(aes(x = Qeff, y = ..scaled..), colour = "#007d3c") +
ggtitle("Qeff 2018") +
geom_vline(aes(xintercept = median, color = "median"), linetype = "dashed") +
geom_vline(aes(xintercept = q5, color = "5%"), linetype = "dashed") +
geom_vline(aes(xintercept = q95, color = "95%"), linetype = "dashed") +
scale_color_manual(name = "statistics", values = c('5%' = "#0000FF", '95%' = "red", median = "#007d3c")) +
theme(panel.background = element_blank(), axis.line = element_line(colour = "black"),
plot.title = element_text(lineheight = .8, hjust = 0.5, face = "bold"),
legend.box.background = element_rect(colour = "black"), legend.box.margin = margin(t = 1, l = 1),
legend.title = element_blank()))%>%
ggplotly()
</code></pre>
<p>Then my plot looks like this (without my self-painted parts):</p>
<p><a href="https://i.stack.imgur.com/DFbeZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DFbeZ.png" alt="enter image description here" /></a></p>
<p>Now I want to create a new column <code>group</code> that contains the group number of my data, i.e. add the group to which it falls to the respective <code>Qeff</code>. Group 1 is everything up to <code>5%</code>, group two is everything between <code>5%</code> and <code>median</code>, group 3 is everything between <code>median</code> and <code>95%</code> and group 4 is everything after <code>95%</code>. The <code>group</code> column should only contain the numbers 1 to 4.</p>
<p>How can I do this?</p>
<p>Here is a short snippet of my data table:</p>

TransactionException on mariadb get

<p>Apologies for bit-misleading title.</p>
<p>I have a <code>device-id</code> application, which basically saves any new <code>deviceId</code> sent to system or return details of any <code>deviceId</code> as per request.</p>
<p>This issue is not very frequent but it does pop up <em>now-and-then</em> and google is not helping solve it!</p>
<p>Datastore is on <a href="https://mariadb.com/kb/en/library/mariadb-10135-release-notes/" rel="nofollow noreferrer">MariaDB-10.1.35</a>. Service has a QPS activity of ~2.5k, couple of google links suggested to increase <code>wait_timeout</code> but given the QPS, a wait_timeout of 600seconds is a safe bet.</p>
<p>prod config has:</p>
<pre><code>validationQuery: "/* Health Check */ SELECT 1"
wait_timeout: 600

Interstitial ad with load delay

<p>I'm trying to implement an interstitial ad, and I'd like it to load before, in the application it's happening to load along with the action which causes delay and makes the ad appear well after. I want to make the ad appear right after pressing "adicionar" as shown in the image below:

Why does my url spits out the two // at the end?
|
<p>I am very new to React so bear with me here. I have this button here:</p>
<pre><code>let showButton
if (schema.type === 'belongs_to') {
showButton = (
<Link to={['collections', 'locks', this.props.collectionName]}>
<button>Visa</button>
</Link>
)
}
</code></pre>
<p>This button will redirect to this URL: <code>http://localhost:3000/#/collections/locks/</code> and there is nothing wrong with that, but when I'm adding this: <code>this.props.id</code> which is a legit prop, but the url I get is this: <code>http://localhost:3000/#/collections/locks//</code>. Notice the two <strong>//</strong> at the end.</p>
<h3>My Question</h3>
<p>Why does my url spits out the two <strong>//</strong> at the end? Is it because <code>this.props.id</code> is empty? As I said, I am very new to this. Thankful for all the support!</p>
<h3>Code:</h3>
<p>I just want to say that I'm maintaining this project, so all of the code is not written by me, therefor I might not know <strong>every</strong> little line.</p>
<p>However.. The <code>this.props.id</code> if from here:</p>
<pre><code>class DeleteDocument extends Component {
constructor(props) {
super(props)
this.state = { confirmed: false }
}
render() {
return (
<div className="DeleteDocument">
<div className="box">
<div className="title">
รr du sรคker pรฅ att du vill ta bort dokumentet?
</div>
<label>
<input
type="checkbox"
value={this.state.confirmed}
onChange={e =>
this.setState({ confirmed: !this.state.confirmed })}
/>
Ja, jag รคr sรคker
</label>
<div className="box" />
</div>
<div style={{ marginTop: '20px' }}>
<button
disabled={!this.state.confirmed}
onClick={this.props.deleteDocument}
>
Ta bort
</button>
<div style={{ padding: '15px', borderBottom: '1px solid #ccc' }}>
<Link to={'/collections/locks/${this.props.id}'}> HERE IT IS
<button>Avbryt</button>
</Link>
</div>
</div>
</div>
)
}
}
</code></pre>
<p>So I made a decision to use the same props because it's working here and the naming of it seemed to suit my use for it (don't know if this makes sense).</p>

Reselect checkboxes after Post in included file
|
<p>I have page Search.asp (code below). And Filtered.asp which include Search.asp.</p>
<pre><code> <%
Dim CheckForCheckboxes
CheckForCheckboxes = Request.form("chkBoxes")
response.write "CheckForCheckboxes" & CheckForCheckboxes
%>
<div id="ExSearch" name="ExSearch" >
<script>
// on page load check if this page called from POST and have passed checkboxes to select
var str = '<%=CheckForCheckboxes%>'; // {"Make[]":["AIXAM","CADILLAC","JEEP"],"selCountry[]":["5","4","8"]}
if (!str || str.length === 0) {} else {
var Checked = JSON.parse(str);
// alert works here
// This one not work
$("#ExSearch").find('div.list input[type=radio], input[type=checkbox],div.selector select').each(function () {
// alert do not work here
var $el = $(this);
var name = $el.attr('name');
var value = $el.attr('value');
if (Checked[name] && Checked[name].indexOf(value) !== -1 ) {$el.prop('checked', true);}
});
};
// from here function which select checkboxes and hold them in hidden input field before submit, on submit pass this object with form
$(function() {
$('div.list input[type=checkbox], input[type=radio]').on('change',onValueChange);
$('div.selector select').on('change', onValueChange);
function onValueChange() {
var Checked = {};
var Selected = {};
// Hold all checkboxes
$('div.list input[type=radio]:checked, input[type=checkbox]:checked').each(function () {
var $el = $(this);
var name = $el.attr('name');
if (typeof (Checked[name]) === 'undefined') {Checked[name] = [];}
Checked[name].push($el.val());
});
// Hold all dropdowns
$('div.list select').each(function () {
var $el = $(this);
var name = $el.attr('name');
if (!!$el.val()) {Selected[name] = $el.val();}
});
// Put all together to POST
$.ajax({
url: '/Search.asp',
type: 'POST',
data: $.param(Selected) + "&" + $.param(Checked),
dataType: 'text',
success: function (data) {
// Put response data to page and reselect checkboxes, this works good
$("#ExSearch").html(data).find('div.list input[type=radio], input[type=checkbox],div.selector select').each(function () {
var $el = $(this);
var name = $el.attr('name');
var value = $el.attr('value');
if (Checked[name] && Checked[name].indexOf(value) !== -1 ) {$el.prop('checked', true);}
if (Selected[name]) {$el.val(Selected[name]);}
});
// Hold converted object to string values
$("<input type='hidden' value='' />").attr("id", "chkBoxes").attr("name", "chkBoxes").attr("value", JSON.stringify(Checked)).prependTo("#ajaxform");
}
});
};
});
</script>
<form name="ajaxform" id="ajaxform" action="Filtered.asp" method="POST">
</form>
</div>
</code></pre>
<p>So If page Search.asp starting I check if object passed via form post method, and if passed I need to select checkboxes which is in this object.
So I create object, then I convert it to string with Json.stringify and then catch form post string and convert back to object with JSON.parse</p>
<p>So everything look ok but checkboxes is not selecting and no errors appears.</p>
<p>What now is wrong?</p>

Issue setting up a django database migration for an app with a model that has a relationship to another app in the same project
|
<p>I'm trying to setup two related apps in a django project, where one app's model references the other in a foreign key relationship. This is normally a simple thing, but I'm running into some collisions with app names (one of my apps is called 'account' and that's not unique in my installation) and my subsequent fix to that by adding in specific name/label definitions in a custom AppConfig may also be contributing to the problem.</p>
<p>A little background on my environment:</p>
<ul>
<li>Django 1.8.3</li>
<li>Python 2.7.6</li>
<li>Postgres 9.4.0</li>
<li>using this template for my project structure: <a href="https://github.com/pydanny/cookiecutter-django" rel="nofollow">https://github.com/pydanny/cookiecutter-django</a>. Thanks pydanny!</li>
</ul>
<p>I setup a simple project using this template to demonstrate the problem: <a href="https://github.com/rishikumar/django_test_model" rel="nofollow">https://github.com/rishikumar/django_test_model</a></p>
<p>Here are the relevant parts to the tree:</p>
<pre><code>test/ (project app)
/config ()
/test (main django app)
/account
__init__.py
apps.py
models.py (Has a model called "Account")
/schedule
__init__.py
apps.py
models.py (Has a model called "Schedule" which has a ForeignKey relationship to the Account table)
</code></pre>
<p>Here is the first model class, under the test/account app</p>
<pre><code>class Account(models.Model):
class Meta:
db_table = 'test_account'
</code></pre>
<p>After putting this in place, I added this project to the INSTALLED_APPS as "test.account". I ran makemigrations next.</p>
<pre><code>./manage.py makemigrations test.account
</code></pre>
<p>I was expecting this to uniquely identify the account package underneath the test project, but its only looking for the "account" part of the name. (I couldn't find any documentation explaining why this is the case)</p>
<pre><code>django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: account
</code></pre>
<p>To work around this problem I setup a custom AppConfig for this. in test/test/account/<strong>init</strong>.py I added the following: </p>
<pre><code>default_app_config = 'test.account.apps.AppConfig'
</code></pre>
<p>And to test/test/account/apps.py I added: </p>
<pre><code>class AppConfig(apps.AppConfig):
name = 'test.account'
label = 'test.account'
</code></pre>
<p>Now I can run make migrations as I originally intended and it works as expected. </p>
<pre><code>./manage.py makemigrations test.account
</code></pre>
<p>Incidentally, I gave the model a specific table name because it was specifying "test.account_account" by default and that causes some headaches in the postgres CLI - I have to quote the entire table name to reference it.</p>
<p>I setup the second app the same way - added a default app config and setup the name and label of the app config to be "test.schedule"</p>
<p>Here is the models.py in the schedule app:</p>
<pre><code>from test.account.models import Account
class Schedule(models.Model):
class Meta:
db_table = 'test_schedule'
account = models.ForeignKey(Account)
</code></pre>
<p>Now I run makemigrations on this app:</p>
<pre><code>./manage.py makemigrations test.schedule
</code></pre>
<p>I get the following error:</p>
<pre><code>ValueError: Lookup failed for model referenced by field test.schedule.Schedule.account: test.schedule.test.account.Account
</code></pre>
<p>Notice that the Account class that its trying to access says "test.schedule.test.account.Account" when it should referencing "test.account.Account"</p>
<p>I'm not sure if my solution for the AppConfig entry was the right choice - perhaps there is a better way to uniquely identify an app within the django installation? </p>
<p>I'm guessing that I'm making a bad decision about how to name things in my AppConfig, but I'm not sure how to reconcile the fact that I need to specify an AppConfig to avoid having duplicate application labels while still being able to avoid confusing the lookup for the foreign key reference that the migration tool is using. </p>

Parsing javascript dumped array using Qt into list of points
|
<p>I need to convert a dumped array of points to a list of points in qt using c++ so that I can further debug my application. I use chrome to copy the array object to a file and it will end up like this:</p>
<pre><code>[
{
"x": 0,
"y": 266.48351648351644
},
{
"x": 2.3095238095238093,
"y": 274.3003663003663
},
{
"x": 3.3754578754578755,
"y": 277.6758241758242
}
]
</code></pre>
<p>My strategy is to open the file and find lines that have the character x or y in them and save each consecutive x,y in a point object:</p>
<pre><code>void MainWindow::on_btnOpenFile_clicked()
{
auto path = QFileDialog::getOpenFileName(this, "Browse for a array object file...");
QFile file(path); // works fine
if(file.exists(path) && file.open(QIODevice::ReadOnly)) {
QTextStream stream(&file);
QVector<QPointF> points;
QString currentLine;
qreal x;
qreal y;
// Regex rules for x and y
QRegExp rX(":.*,");
rX.setMinimal(true);
QRegExp rY(":.*");
rY.setMinimal(true);
while(!stream.atEnd()) {
bool xFound = false, yFound = false;
currentLine = stream.readLine();
// Get X value
if(currentLine.contains("x", Qt::CaseInsensitive)) {
auto pos = rX.indexIn(currentLine);
if(pos == 0) {
x = rX.capturedTexts()[0].toDouble();
xFound = true;
}
} else if(currentLine.contains("y", Qt::CaseInsensitive)) { // Get Y value
auto pos = rY.indexIn(currentLine);
if(pos == 0) {
y = rY.capturedTexts()[0].toDouble();
yFound = true;
}
}
if(xFound)
points.push_back({x,y});
}
}
}
</code></pre>
<p>I just noticed that my approach will not work because I only evaluate one line in each iteration of the while loop...and that will never work.</p>
<p>Second is my regex that even matches the <code>[</code> character!</p>
<p>Is there any smarter way of doing this parsing? the dumped file looks like a JSON to me but maybe not? if it is compatible with JSON is there an automated way of converting it?</p>

CSV to XML using XSLT-1.0 group by first 0 value
|
<p>I would like to use the XSLT 1.0 engine to transform a CSV file to an XML document. The CSV file contains documents for each customer with a flexible amount of document lines. Each new document starts with 0.</p>
<p><strong>CSV example:</strong></p>
<pre><code><root>
0;15-01-2022;Customer1
1;Dual monitors;50
2;Laser mouse;10.50
0;21-1-2022;Customer5
1;Multi-jet printer;100
0;30-1-2022;Customer8
1;Goods returned;-200
2;Basic keyboard;300
</root>
</code></pre>
<p>Here's the result <strong>XML document</strong> I would like to get:</p>
<pre><code><Documents>
<Document>

A dataset with Int64, Float64 and datetime64[ns] gets converted to object after applying Pandas fillna method
|
<p>I am using Kaggle's dataset (<a href="https://www.kaggle.com/datasets/claytonmiller/lbnl-automated-fault-detection-for-buildings-data" rel="nofollow noreferrer">https://www.kaggle.com/datasets/claytonmiller/lbnl-automated-fault-detection-for-buildings-data</a>)</p>
<p>I have A dataset with Int64, Float64, and datetime64[ns] datatypes; after using the pandas fillna method, however, all of my data type changes to object datatype.</p>
<p>Could anyone assist me with what I need to do to retain the original data types after the Pandas conversion?</p>
<p>The following is the code I use:</p>
<pre><code>import pandas as pd

<p>If I do a <code>df.dtypes</code> I can see the correct datatypes however, after the following lines of code, it changes to object datatype.</p>

Microsoft Access Report - Sub Report carries over 2 pages, but access thinks it is one?
|
<p>I've reworded the title and this description because the last one didn't make much sense.</p>
<p>Basically, I have a report that displays business details. Some of these details include:</p>
<ul>
<li><strong>Business Name</strong></li>
<li><strong>Address</strong></li>
<li><strong>Documents</strong></li>
<li><strong>Clients</strong></li>
</ul>
<p>When the report is formatted (Print View), the business name and it's corresponding page number are added to a table(<strong>BusinessPage</strong>). The code for this is placed in the 'On Format' event of the first group header, I have listed the code below:</p>
<pre><code>Dim RST As DAO.Recordset
Set RST = CurrentDb.OpenRecordset("BusinessPage", dbOpenTable)
RST.AddNew
RST![Business Name] = BUSName
RST![Business Page] = Me.Page
RST.Update
RST.Close
CurrentDb.Execute "SELECT DISTINCT * INTO t_temp FROM BusinessPage"
CurrentDb.Execute "DELETE FROM BusinessPage"
CurrentDb.Execute "INSERT INTO BusinessPage SELECT * FROM t_temp"
CurrentDb.Execute "DROP TABLE t_temp"
</code></pre>
<p>The table will look something like this:</p>
<pre><code>Business Name Page No
Business 1 3
Business 2 4
Business 3 6 'This indicates that Business 2 spans over two pages as page 5 is skipped'
Business 4 7
</code></pre>
<p>In the report header, I have two things:</p>
<ul>
<li><strong>A cover page</strong></li>
<li><strong>An Index Sub Report/Page</strong></li>
</ul>
<p>The index page (Sub Report) takes the information from the table(<strong>BusinessPage</strong>) and lists all of the businesses in the report, along with the page numbers that they start on.</p>
<p>Now that you have an idea of how this works, here is my problem:
The sub report works fine if it only takes up one page. The issue I have is when the sub report lists too many records and it carries over onto the second page. For some reason, access still thinks that the sub report is on one page, even though it's created another page. Despite it thinking that, the footer that contains the code ([Page]) displays correctly. However, the code that displays the total amount of pages ([Pages]) is wrong. At the end of the report, the footer will say something like this:
Page 50 of 49
<br></p>
<p>The other issue I have is that the information that is added to the table is wrong when the sub report exceeds one page. The information added is in assumption that the sub report is still on one page.
<br></p>
<p>For example, when the sub report takes up one page:</p>
<pre><code>Page 1: Cover Page
Page 2: Sub Report/Index
Page 3: Business 1
</code></pre>
<p>Sub report will correctly display:</p>
<pre><code>Business 1 Page 3
</code></pre>
<p><br></p>
<p>When the sub report takes up 2 pages:</p>
<pre><code>Page 1: Cover Page
Page 2: Sub Report/Index
Page 3: Sub Report/Index
Page 4: Business 1
</code></pre>
<p>The sub report/index page will still display:</p>
<pre><code>Business 1 Page 3
</code></pre>
<p>Whereas it should be displaying it as:</p>
<pre><code>Business 1 Page 4
</code></pre>
<p><br>
<br></p>
<p>Does anybody have any idea of how I can correct this? I have a feeling it may be because the sub report is in the report header (But I need it there because it will only ever be displayed once at the start of the report). Is there another way to create a secondary report header to test this theory?</p>
<p>Let me know if anybody thinks of any other solutions!</p>
<p><strong>Edit:</strong>
I moved the sub report into it's own group/header, away from the Report Header.
This didn't change anything, access still thinks it's displaying on one page even though it's not. I have another hunch that access thinks it's on one page due to the size of the sub report in design view? The sub report in design view will fit on one page before bringing in the data, could this be the issue? How would I go about fixing that?
<br></p>
<p>I was thinking, maybe an if statement to decide how big the sub report turns out, if it's the length of 2 pages, then alter the code to become:</p>
<pre><code>RST![Business page] = Me.Page + 1
</code></pre>
<p>This is still quite a shoddy fix though, and I'm not sure how I'd go about writing the if statement to calculate the length of the page</p>

How can I pass character strings as independent parameters after a `+`?
|
<p>Before you mark as dup, I know about <a href="https://stackoverflow.com/questions/7836972/use-character-string-as-function-argument?noredirect=1&lq=1">Use character string as function argument</a>, but my use case is slightly different. I don't need to pass a parameter INSIDE the function, I would like to pass a dynamic number of parameters after a <code>+</code> (think <code>ggplot2</code>).</p>
<p>(Note: Please don't format and remove the extra-looking ####, I have left them in so people can copy paste the code into R for simplicity).</p>
<p>This has been my process:</p>
<p>#### So let's reproduce this example:</p>
<pre><code>library(condformat)
condformat(iris[c(1:5,70:75, 120:125),]) +
rule_fill_discrete(Species) +
rule_fill_discrete(Petal.Width)
</code></pre>
<p><a href="https://i.stack.imgur.com/x1FRR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/x1FRR.png" alt="enter image description here"></a></p>
<p>#### I would like to be able to pass the two <code>rule_fill_discrete()</code> functions dynamically (in my real use-case I have a variable number of possible inputs and it's not possible to hardcode these in).</p>
<p>#### First, create a function to generalize:</p>
<pre><code>PlotSeries <- function(x){
b=NULL
for (i in 1:length(x)){
a <- paste('rule_fill_discrete(',x[i],')',sep="")
b <- paste(paste(b,a,sep="+"))
}
b <- gsub("^\\+","",b)
eval(parse(text = b))
}
</code></pre>
<p>#### Which works with one argument</p>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) +
PlotSeries("Species")
</code></pre>
<p>#### But not if we pass two arguments:</p>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) +
PlotSeries(c("Species","Petal.Width"))
</code></pre>
<blockquote>
<p>Error in rule_fill_discrete(Species) + rule_fill_discrete(Petal.Width) :
non-numeric argument to binary operator</p>
</blockquote>
<p>#### It will work if we call each individually</p>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) +
PlotSeries("Species") +
PlotSeries("Petal.Width")
</code></pre>
<p>#### Which gives us an indication as to what the problem is... the fact that it doesn't like when the <code>rule_fill_discrete</code> statements are passed in as <strong>one</strong> statement. Let's test this:</p>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) +
eval(rule_fill_discrete(Species) +
rule_fill_discrete(Petal.Width) )
</code></pre>
<blockquote>
<p>Error in rule_fill_discrete(Species) + rule_fill_discrete(Petal.Width) :
non-numeric argument to binary operator</p>
</blockquote>
<p>#### Fails. But:</p>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) +
eval(rule_fill_discrete(Species)) +
eval(rule_fill_discrete(Petal.Width) )
</code></pre>
<p>#### This works. But we <strong>need</strong> to be able to pass in a GROUP of statements (that's kinda the whole point). So let's try to get the eval statements in:</p>
<pre><code>Nasty <- "eval(rule_fill_discrete(Species)) eval(rule_fill_discrete(Petal.Width))"
condformat(iris[c(1:5,70:75, 120:125),]) + Nasty #### FAIL
</code></pre>
<blockquote>
<p>Error in <code>+.default</code>(condformat(iris[c(1:5, 70:75, 120:125), ]), Nasty) :
non-numeric argument to binary operator</p>
</blockquote>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) + eval(Nasty) #### FAIL
</code></pre>
<blockquote>
<p>Error in <code>+.default</code>(condformat(iris[c(1:5, 70:75, 120:125), ]), eval(Nasty)) :
non-numeric argument to binary operator</p>
</blockquote>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) + parse(text=Nasty) #### FAIL
</code></pre>
<blockquote>
<p>Error in <code>+.default</code>(condformat(iris[c(1:5, 70:75, 120:125), ]), parse(text = Nasty)) :
non-numeric argument to binary operator</p>
</blockquote>
<pre><code>condformat(iris[c(1:5,70:75, 120:125),]) + eval(parse(text=Nasty)) #### FAIL
</code></pre>
<blockquote>
<p>Error in eval(rule_fill_discrete(Species)) + eval(rule_fill_discrete(Petal.Width)) :
non-numeric argument to binary operator</p>
</blockquote>
<p>So how can we do it? </p>

gulp plugin - to merge broken js files into one js file?
|
<p>I have read all the answers on the internet that I could find on this subject in last two days. Now I am just searching for gulp plugin that can merge broken js files into one big js file and not to throw error in terminal caused by unclosed function in one js file.</p>
<p>Explanation:</p>
<p>I have created js app built with modules.
At the very beginning I didn't knew that this will become big app and therefore I have wrote js code in one file.</p>
<p>Now I have come to an idea to split app.js file like this:</p>
<p><strong>app-start.js</strong> (Named IIFE function open)</p>
<p>module1.js</p>
<p>module2.js</p>
<p>etc.</p>
<p><strong>app-end.js</strong> (Named IIFE function closed)</p>
<p>I am using gulp as task runner and gulp-concat which works perfectly.</p>
<p>Problem is that when I try to break IIFE function in two files (app-start.js, app-end.js) then gulp doesn't wanna build bundle.js file.
I get error in terminal that I should repair my js code in<br>
app-start.js</p>
<p>So, my question is,<br>
do You maybe know about gulp plugin that will merge multiple js files in given order and never mind the js code errors in those files?</p>
<p>This is my gulp.js code:</p>
<pre><code> var gulp = require('gulp'),
sass = require('gulp-sass'),
uglify = require('gulp-uglify'),

autoprefixer = require('gulp-autoprefixer'),
browserSync = require('browser-sync').create(),
sourceMap = require('gulp-sourcemaps'),
babel = require('gulp-babel');
gulp.task('sass', function() {
gulp.src('resources/sass/config-normalize.sass')
//.pipe(sourceMap.init())
.pipe(sass.sync().on('error', sass.logError))
.pipe(autoprefixer({browsers: ['last 30 versions']}))
.pipe(sass({outputStyle: 'expanded'})) //expanded - compressed
//.pipe(sourceMap.write('.'))
.pipe(gulp.dest('configurator/css'));
gulp.src('resources/sass/config-style.sass')
//.pipe(sourceMap.init())
.pipe(sass.sync().on('error', sass.logError))
.pipe(autoprefixer({browsers: ['last 30 versions']}))
.pipe(sass({outputStyle: 'expanded'})) //expanded - compressed
//.pipe(sourceMap.write('.'))
.pipe(gulp.dest('configurator/css'))
.pipe(browserSync.stream());
});

'resources/js/050-main.js',
'resources/js/100-my-modules.js',
'resources/js/app-end.js'
])
//.pipe(plumber())
.pipe(babel({
presets: ['es2015']
}))
.pipe(concat('all.js'))
//.pipe(uglify())
.pipe(gulp.dest('configurator/js'))
.pipe(browserSync.stream());
});
gulp.task('php', function() {
gulp.src('./**/*.php')
.pipe(browserSync.stream());
});
gulp.task('browser-sync', function() {
browserSync.init({
proxy: "localhost" //Upisi path do projekta na local hostu bez http://
});
});
gulp.task('images', function() {
return gulp.src('assets/images-uncompressed/**/*')
.pipe(imagemin({
progressive: true,
svgoPlugins: [{removeViewBox: false}],
use: [pngquant()]
}))
.pipe(gulp.dest('build/images'));
});
gulp.task('watch', function() {
gulp.watch('./**/*.php', ['php']);
gulp.watch('resources/sass/**', ['sass']);
gulp.watch('resources/js/**', ['scripts']);
//gulp.watch('resources/images-uncompressed/*', ['images']);
});
gulp.task('default', ['sass', 'scripts', 'php', 'browser-sync', 'watch']);

Heroku double '/' problem - node js backend, 404 error
|
<p>I have deployed my backend on heroku and I have a test get request's response on <code>/</code></p>
<pre><code>app.get('/', (req, res) => {
res.send("Hello, World. The app is running!");
});
</code></pre>
<p>On hitting the <code>/</code> end point that is <a href="https://ayush-portfolio-backend.herokuapp.com/" rel="nofollow noreferrer">https://ayush-portfolio-backend.herokuapp.com/</a>, I get the expected <code>GET</code> output.</p>
<p>But, when from the frontend react app, I hit any <code>POST</code> endpoint, e.g.:-</p>
<pre><code>// index.js
app.use('api/portfolios/', (require('./routes/portfolio')));
// portfolio route
router.post('/getportfolios', async (req, res) => {...});
</code></pre>
<p>I am unable to get any response on the frontend.</p>
<p>As suggested by heroku docs, when I do <code>heroku logs</code><br />
I get the following error:-</p>
<pre><code>2022-09-21T07:57:41.743176+00:00 heroku[router]: at=info method=OPTIONS path="//api/portfolios/getportfolios" host=ayush-portfolio-backend.herokuapp.com request_id=0aff16a8-8aee-499e-a69e-4bdf8d583e6d fwd="103.164.24.154" dyno=web.1 connect=0ms service=5ms status=204 bytes=312 protocol=https2022-09-21T07:57:41.808753+00:00 heroku[router]: at=info method=OPTIONS path="//api/portfolios/getportfolios" host=ayush-portfolio-backend.herokuapp.com request_id=3c1974f2-522c-47b8-92d8-2f201bd0e2ab fwd="103.164.24.154" dyno=web.1 connect=0ms service=1ms status=204 bytes=312 protocol=https2022-09-21T07:57:42.054955+00:00 heroku[router]: at=info method=POST path="//api/portfolios/getportfolios" host=ayush-portfolio-backend.herokuapp.com request_id=6092ee53-d98d-4fa0-9fff-abd46554de56 fwd="103.164.24.154" dyno=web.1 connect=0ms service=10ms status=404 bytes=445 protocol=https

</code></pre>
<p>I don't know what is causing the following error. The app works perfectly fine on the local environment, but don't know why the problem has occured.</p>
<p>I am a beginner for heroku and I don't know much about it, also i searched the google and stackoverflow for the error but did not find any relevant solution to the problem.</p>
<p>I just assume that the error can be because of some double / <code>//</code> creating in the path as in the error it is shown e.g. <code>path='//api/portfolios/getportfolios'</code>. So, I also tried removing the / from frontend and everywhere else trying to make it sinbgle / but this didn't solve the problem.</p>
<p>Can someone please guide me to find the solution of the above problem.
Thank you!</p>

Parse Facebook dialog:andParams causes login screen
|
<p>I have been using the Parse Facebook implementation for a while and now I am getting some weird behaviors after updating.</p>
<p>I am logging in a user successfully using</p>
<pre><code>NSArray *permissions = [NSArray arrayWithObjects:@"user_about_me",
@"user_relationships",@"user_birthday",@"user_location",
@"email", nil];
[PFFacebookUtils logInWithPermissions:permissions
block:^(PFUser *user, NSError *error) {
if (!user) {
if (!error) { // The user cancelled the login
NSLog(@"Uh oh. The user cancelled the Facebook login.");
} else { // An error occurred
NSLog(@"Uh oh. An error occurred: %@", error);
}
}
else if (user.isNew) { // Success - a new user was created
NSLog(@"Is New");
}
else { // Success - an existing user logged in
NSLog(@"Existing");
}
}];
</code></pre>
<p>Which works fine. Now when I want to bring up the post dialog to the user I use</p>
<pre><code>NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"MY_APP_ID", @"app_id",
caption, @"name",
link, @"link",
description, @"description",
name, @"caption",
picture, @"picture",
nil];
[[PFFacebookUtils facebook] dialog:@"feed" andParams:params andDelegate:self];
</code></pre>
<p>Which is bringing up the facebook login popup even though the user is already logged on and is using ios6.0 with the facebook settings configured. </p>
<p>Can anyone help me explain what is happening so that I can avoid the user basically having to sign in more than once just to post?</p>

SAS EG (SQL) deleting rows where max value in one column
|
<p>I need to delete all the rows with a max value of <code>duty_perd_id</code> where the <code>rotn_prng_nbr</code> and <code>empl_nbr</code> are the same (not the same to each other, but the max where of all of the rows where those two remain constant). From the table below it should delete rows 3,7 and 9.</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>rotn_prng_nbr</th>
<th>empl_nbr</th>
<th>duty_perd_id</th>
</tr>
</thead>
<tbody>
<tr>
<td>B93</td>
<td>12</td>
<td>1</td>
</tr>
<tr>
<td>B93</td>
<td>12</td>
<td>2</td>
</tr>
<tr>
<td>B93</td>
<td>12</td>
<td>3</td>
</tr>
<tr>
<td>B21</td>
<td>12</td>
<td>1</td>
</tr>
<tr>
<td>B21</td>
<td>12</td>
<td>2</td>
</tr>
<tr>
<td>B21</td>
<td>12</td>
<td>3</td>
</tr>
<tr>
<td>B21</td>
<td>12</td>
<td>4</td>
</tr>
<tr>
<td>B21</td>
<td>18</td>
<td>1</td>
</tr>
<tr>
<td>B21</td>
<td>18</td>
<td>2</td>
</tr>
</tbody>
</table>
</div>
<p>using SAS EG. Right now all have is below:</p>
<p>Option 1:</p>
<pre><code> create table middle_legs as
select t.*
from actual_flt_leg as t
where t.duty_perd_id < (select max(t2.duty_perd_id)
from actual_flt_leg as t2
where t2.rotn_prng_nbr = t.rotn_prng_nbr and
t2.empl_nbr = t.empl_nbr
);
</code></pre>
<p>this works exactly as intended, but is incredibly slow. The other thought that I had but couldnt quite finish was as follows.</p>
<p>Option 2:</p>
<pre><code>create table last_duty_day as
Select * from actual_flt_leg
inner join (
select actual_flt_leg.Rotn_Prng_Nbr,actual_flt_leg.empl_nbr, max(duty_perd_id) as last_duty
from actual_flt_leg
group by actual_flt_leg.Rotn_Prng_Nbr, actual_flt_leg.empl_nbr
) maxtable on
actual_flt_leg.Rotn_Prng_Nbr = maxtable.Rotn_Prng_Nbr
and actual_flt_leg.empl_Nbr = maxtable.empl_Nbr
and actual_flt_leg.duty_perd_id = maxtable.last_duty;
</code></pre>
<p>option 2 finds all the highest <code>duty_perd_id</code> for the given pair, and I was wondering if there was any "reverse join" that could only show the rows from the original table that do not match this new table i created in option 2.</p>
<p>If there is a way to make option 1 faster, finish option 2, or anything else i cant think of id appreciate it. Thanks!</p>

How to create an email template in Gmail that sends a summary of the upcoming week to multiple email addresses
|
<p>I have a Google Calendar set up for industry events for my co-workers, and I'd like to send a weekly email (through Gmail) that summarizes the following week's events in this Google Calendar. I'm comfortable creating the visual template and setting it up to auto-send weekly, but I need help pulling in the Google Calendar info. </p>
<p>I looked into plug-ins for this, but I can't use them on my work email.</p>
<p>I found code for displaying Google Calendar event info on a website, but I haven't used a public apiKey or a web app client Id before. I'm wary about using them for security reasons because this is for my work emailโI'm not confident in setting this up securely.</p>

SQL to JSON - Create a Json Array
|
<p>I have the below data:</p>
<pre><code>CREATE TABLE mytable
(
ID int,
Product nvarchar(50),
Usage nvarchar(255),
);
INSERT INTO mytable VALUES (99346,'Universal light','Art and Culture');
INSERT INTO mytable VALUES (99346,'Universal light','Health and Care');
INSERT INTO mytable VALUES (99346,'Universal light','Hotel and Wellness');
INSERT INTO mytable VALUES (99346,'Universal light','Education and Science');
</code></pre>
<p>And I have created the following code to get my JSON output:</p>
<pre><code>SELECT DISTINCT T1.ID
,T1.Product
,(SELECT T2.Usage
FROM mytable T2
WHERE T1.ID=T2.ID
FOR JSON PATH) as 'Usage'
FROM mytable T1
FOR JSON PATH
</code></pre>
<p>It outputs the following results:</p>
<pre class="lang-json prettyprint-override"><code>[
{
"ID": 99346,
"Product": "Universal light",
"Usage": [
{
"Usage": "Art and Culture"
},
{
"Usage": "Health and Care"
},
{
"Usage": "Hotel and Wellness"
},
{
"Usage": "Education and Science"
}
]
}
]
</code></pre>
<p>I would like to have the results as below, but can't figure out how to change the syntax:</p>
<pre><code>[
{
"ID": 99346,
"Product": "Universal light",
"Usage": [ "Art and Culture" , "Health and Care" , "Hotel and Wellness" , "Education and Science"
]
}
]
</code></pre>
<p>Any help on this much appreciated.</p>
<p>EDIT</p>
<p>If I use this initial data, where at the end of line 3 I have an extra ' ' the solution does not work, no error or warning:</p>
<pre class="lang-sql prettyprint-override"><code>INSERT INTO mytable VALUES (99346,'Universal light','Art and Culture');
INSERT INTO mytable VALUES (99346,'Universal light','Education and Science');
INSERT INTO mytable VALUES (99346,'Universal light','Health and Care ');
INSERT INTO mytable VALUES (99346,'Universal light','Hotel and Wellness');
INSERT INTO mytable VALUES (99346,'Universal light','Offices and Communication');
INSERT INTO mytable VALUES (99346,'Universal light','Presentation and Retail');
</code></pre>
<p>I have tried to use TRIM, as you can see below:</p>
<pre class="lang-sql prettyprint-override"><code>SELECT Distinct ID
,Product
,json_query(QUOTENAME(STRING_AGG('"' + STRING_ESCAPE(TRIM(Usage), 'json') + '"', char(44)))) AS 'Usage'
FROM mytable
GROUP BY ID
,Product
FOR JSON PATH;
</code></pre>
<p>Unfortunately it does not work and the whole array 'Usage' is somehow ignored, see results:</p>
<pre class="lang-json prettyprint-override"><code>[
{
"ID": 99346,
"Product": "Universal light"
}
]

UIManager in Button Action
|
<p>I have one <code>LoginScreen</code> and one <code>MainWindow</code>. When connection attempt succeed to DB, LoginScreen <code>disposed</code> and MainWindow appear.</p>
<p>I have one button has <code>ActionListener</code> for create a <code>JOptionPane</code>. Code succesfully working actually. I have three problems in <code>Painting</code> i think. Let me explain problems one by one;</p>
<p><strong>Problem 1;</strong></p>
<pre><code>UIManager UI=new UIManager();
Object paneBG = UI.get("OptionPane.background");
Object panelBG = UI.get("Panel.background");
UI.put("OptionPane.background", Color.red);
UI.put("Panel.background", Color.red);
String[] buttons2 = { "EXIT", "OK" };
int rc2 = JOptionPane.showOptionDialog(MainWindow.this,
panel,
"User Input",
JOptionPane.INFORMATION_MESSAGE,
JOptionPane.PLAIN_MESSAGE,
icon,
buttons2,
buttons2[1]
);
UI.put("OptionPane.background", paneBG);
UI.put("Panel.background", panelBG);
</code></pre>
<p>I use above code for change <code>background color</code> of <code>OptionPane</code>, show to user and rollback the UI colors to original.</p>
<p>If i directly run the <code>MainWindow</code> and click the button, color changed (<em>sure panel and buttons area keep original colors in OptionPane, but other OptionPane areas turn to red. This is another issue</em>) like this;</p>
<p><a href="https://i.stack.imgur.com/QnCYv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QnCYv.png" alt="enter image description here"></a></p>
<p>But when i come from <code>LoginScreen</code>, login attempt succeed, LoginScreen <code>disposed</code> and MainWindow appear. I click to same button but <code>OptionPane</code> not painted now, like this;</p>
<p><a href="https://i.stack.imgur.com/mxGY0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/mxGY0.png" alt="enter image description here"></a></p>
<p><strong>Problem 2;</strong></p>
<p>I have another button in MainWindow and it create another OptionPane. I directly run the MainWindow and click first button (which has change the UI color and rollback action), close it than click second button (which has another OptinPane) OptionPane still painted so UI colors not rollback to default values.</p>
<p><strong>Problem 3;</strong></p>
<p>If we solve the first and second problem, How can i make <code>transparent</code> these inner panels (which has label and textfield panel one and buttons one)</p>

How to make Xcode display comments below user-defined methods?
|
<p>If we type a method from Apple API, Xcode will display method functions below the auto-complete pop-up list. But typing a user-defined method, it shows nothing.</p>
<p>Is there a way to tell Xcode to display some descriptions that I defined by myself to show how to use the user-defined methods?</p>
<p>Thank you!!!</p>
<hr />
<p>@HAS:</p>
<p>I follow your instruction till Step 12, and create a simple test class in .h file as:</p>

<p>And besides, my Xcode version is 4.5.1 and OS X 10.8.</p>
<p>Xcode is not installed into /Applications folder but simply put at desktop. Does it matter?</p>

<p>@ HAS, again</p>

JSON.NET Serialize as Parent Type
|
<p>I am working on a project where I would like to save the state of an object using human-readable JSON. However, I am running into issues when the originating object of serialization is not the base class. As an example, here is a class and base class:</p>
<pre><code>public class TeaPot
{
public TeaPot()
=> Console.WriteLine("I want this.");
}
public sealed class TeaPotFactory : TeaPot
{
public TeaPotFactory()
: base()
=> Console.WriteLine("I do not want this!");
}
TeaPot greenTea = new TeaPotFactory();
string json = JsonConvert.SerializeObject(greenTea);
</code></pre>
<p>The string <code>json</code> will then contain the following content:</p>
<pre><code> {
"$type": "Project.Factories.TeaPotFactory, TeaShop",
"Name": "Green Tea",
"Price": 5.99,
}
</code></pre>
<p>This means when the JSON is deserialized the factory constructor will run again causing unintended side-effects. Example console output:</p>
<pre><code># I want this.
# I do not want this!
</code></pre>
<p>This happens even if I specify the deserialization type as the base class (<code>JsonConvert.DeserializeObject<TeaPot></code>).</p>
<p>I need and have purposefully turned on explicit types for the JSON output as there are types that come from the same base implementation.</p>
<p>How can I get Newtonsoft.Json (JSON.NET) to define the type of the object as its base class? I know with Newtonsoft you can define your own converter, but this would not be an optimal solution as it adds yet another class and a lot of boilerplate code.</p>
<p>The original code for serialization and deserialization was requested:</p>
<pre><code>[Singleton]
public static class Serializer
{
public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings()
{
TypeNameHandling = TypeNameHandling.Objects,
TypeNameAssemblyFormatHandling = TypeNameAssemblyFormatHandling.Simple,
Formatting = Formatting.Indented,
MissingMemberHandling = MissingMemberHandling.Error,
NullValueHandling = NullValueHandling.Include
};
}
public class Bundle {/* ... */}
public class BundleFactory : Bundle {/* ... */}
public sealed class BundleCollection : ISerializable
{
public Bundle[] Bundles
{ get; set; }
public override string Serialize()
=> JsonConvert.SerializeObject(this, Serializer.Settings);
}
</code></pre>
<p>Here is a segment of the output when I output BundleCollection:</p>
<pre><code>{
"Bundles": [
{
"$type": "Integration.Factories.BundleFactory, IntegrationService",
"Name": "FisherScientific",
"Transporters": [
{
"$type": "Integration.Transport.LocalSftp, IntegrationProvider",

}
],

"Mapping": {
"Customer": "A",

}

]
}

Run Python script over multiple folders
|
<p>Today im working with a Python script, this script takes multiple CSV files that are inside a folder and generate a CSV output file with averages by colums, in addition i also have multiple similar folders.
But what i do, is change manually the name of the folder and the name of the output file, as you can imagine, this process is very hard.
What I am looking for, is to do it for each folder respecting the order and the name of each corresponding folder in name and content of each output file.</p>
<p>I was trying using the next in my python script</p>
<pre><code>scriptname,f1name,f2name = sys.argv
</code></pre>
<p>I also use a bash script to make it, but in this bash script, i can change the python script to run it over multiple files inside a folder, but not for multiple folders</p>
<pre><code>#!/usr/bin/env bash
find ./escen10 -type f -name '*.csv' -print0 |
while IFS= read -r -d $'\0' line; do
nname=$(echo "$line" | sed "s/ecn/encn/")
python3 generator2.py $line $nname
done
</code></pre>
<p>The python script is the next:</p>
<pre><code>import os
import sys
from os import listdir
from csv import DictReader
from os import walk
from os import scandir
import numpy as np
import pandas as pd
scriptname,f1name,f2name = sys.argv
#delimiter = ';'
#dataInFolderPath = './nodes_escen1_1/'
#outputFile = 'results_escen1_1.csv'
delimiter = ';'
dataInFolderPath = f1name
outputFile = f2name
dataInFiles = sorted(listdir(dataInFolderPath),key=lambda x: int(x.split('_')[1]))
#sorted_files = sorted(dataInFolderPath)
lines = []
nodes = {}
for fileName in dataInFiles:
file = open(dataInFolderPath + fileName)
data = DictReader(file, delimiter=delimiter)
for line in data:
if not line['node_code'] in nodes.keys():
nodes[line['node_code']] = []
nodes[line['node_code']].append([
line['node_code'],
line['throughput[Mbps]'],
line['data_packets_sent'],
line['data_packets_lost'],
line['rts_cts_sent'],
line['rts_cts_lost']
])
file.close()
output = ''
maxData = max([len(nodes[n]) for n in nodes])
keys = list(nodes.keys())
keys.sort()
for i in range(maxData):
if i == 0:
output += ';'.join(['node_code;throughput[Mbps];Data packets_sent;Data_packets lost;rts_cts_sent;rts_cts_lost'] * len(keys)) + '\n'
for key in keys:
if key != keys[0]:
output += ';'
if i >= len(nodes[key]):
output += ';;;;;'
continue
output += ';'.join(nodes[key][i])
output += '\n'
f = open(outputFile, 'w')
f.write(output)
f.close()
data = pd.read_csv(outputFile,sep=';')
data = data.append({'node_code':"Promedio"},ignore_index=True)
lenght = len(data["node_code"])
for i in range(len(data.columns)//6):
if i ==0:
data['throughput[Mbps]'].iloc[lenght-1] = np.average(data['throughput[Mbps]'][:-1])
else:
data['throughput[Mbps].%i'%i].iloc[lenght-1] = np.average(data['throughput[Mbps].%i'%i][:-1])
data.to_csv(outputFile,sep=';')
print(outputFile)
</code></pre>
<p>For this reason, i hope you can help me to automate this process, using what I have available or with some other more efficient solution to realize this task, thank you in advance for any useful help, regards!</p>

<p>It seems like the error is about the package I installed, multicast-dns, which uses the <code>os</code> core module. I know that if I had control over the multicast-dns package I could switch <code>os</code> to the browserify os module, but i don't. Is there a way to fix this without having the clone <code>multicast-dns</code>?</p>
<p>Thanks!</p>

<p>In the new Drive Api v3, I didnโt find the methods that allow to preserve the functionality of the program. In one of the examples from Google suggests using SAF. But SAF works through android.net.Uri. It allows to get the name of the file, but it does not provide for the file ID.</p>

Problems with form validation using PHP
|
<p>I have a simple form on my website that I need to do server side validation on. If user enters incorrect data or leaves a field blank, the user should be re-shown the form with their submitted data pre-filled into the fields.</p>
<p>My form code looks like this</p>
<pre><code><!--Contact form-->
<form name="contactform" action="validate.php" method="post">
Name:
<input type="text" name="name" value=""><br>
<span class="error">* <?php echo $nameError; ?></span><br>
Email:
<input type="text" name="email" value="">
<span class="error">* <?php echo $emailError; ?></span><br>
Category:
<select name="category">
<option value="" disabled selected>Select</option>
<option value="shipping">Sales</option>
<option value="returns">Returns</option>
<option value="shipping">Shipping</option>
<option value="other">Other</option>
</select><br>
<textarea rows="10" cols="40" name="message" placeholder = "Send us a message"></textarea><br>
<input type="submit" name="submit" value="Submit" onclick="validate()">
</form>
</code></pre>
<p>At the moment all I'm testing to validate is the name and email fields. My problem is that when I load the page I immediately get errors saying "Notice: Undefined variable: nameError " which has to do with these lines in the code</p>
<pre><code><span class="error">* <?php echo $nameError; ?></span><br>
<span class="error">* <?php echo $emailError; ?></span><br>
</code></pre>
<p>However I know the validations are working because I placed echo statements in my validate.php file to test this. If I submit the form with incorrect or correct data, it will take me to a blank validate.php page that just displays the echo statements </p>
<p>Here is my code for validate.php
<pre><code>## Initialise varialbes to null ##
$nameError ="";
$emailError ="";
$categoryError ="";
$messageError ="";
$name = $_POST['name'];
## On submitting form below function will execute ##
if(isset($_POST['submit'])){
if (empty($_POST["name"])) {
$nameError = "Name is required";
echo "name required";
echo " ";
} else {
//$name = test_input($_POST["name"]);
//check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/", $name)) {
$nameError ="Only letters and white space allowed";
echo "Invalid name";
}
}
if(empty($_POST["email"])) {
$emailError = "Email is required";
echo "email required";
} else {
//$email = test_input($_POST["email"]);
//check if email syntax is valid or not
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]/", $email)) {
$emailError = "You did not enter a vaild email";
echo "invalid email";
}
}
}
?>
</code></pre>
<p>So I know my validations are working, the problem is that they are not displaying on the form itself. Can anyone offer a solution on how to fix this?
I've included a picture of one of the error messages I get when I load up the page <a href="http://i.stack.imgur.com/YgtOd.png" rel="nofollow">Error message on page load</a></p>

C# to Java UTF8 string over TCP
|
<p>I'm unable to send a UTF-8 string from a C# server to a Java client due to an EOF error in the client. How do I properly configure the C# server? I assume the error lies there because this client works with the Java server shown below.</p>
<p>Java client's receive function does this (this also works if I receive from a <em>Java</em> server, shown below):</p>
<pre><code>DataInputStream dataInputStream = new DataInputStream(socket.getInputStream()); //The constructor initialises a field, using the socket object.
StringBuilder inputMessage = new StringBuilder();
inputMessage.append((String) dataInputStream.readUTF());
</code></pre>
<p>Desired C# server:</p>
<pre><code> static async Task Main(string[] args)
{
TcpListener server = new TcpListener(IPAddress.Any, 34567);
server.Start();
byte[] bytes = new byte[4096];
byte[] responseBytes;
using (var client = await server.AcceptTcpClientAsync()){
using(var tcpStream = client.GetStream())
{
await tcpStream.ReadAsync(bytes, 0, bytes.Length);
var playerNumber = Encoding.UTF8.GetString(bytes);
Console.WriteLine("Player " + playerNumber + " connected."); //java client to server works.
StringBuilder outputMessage = new StringBuilder("Some output");
responseBytes = Encoding.UTF8.GetBytes(outputMessage.ToString());
await tcpStream.WriteAsync(responseBytes, 0, responseBytes.Length); //This doesn't work...
}
server.Stop();
}
}
</code></pre>
<p>The error:</p>
<pre><code>java.io.EOFException
at java.base/java.io.DataInputStream.readFully(DataInputStream.java:201)
at java.base/java.io.DataInputStream.readUTF(DataInputStream.java:613)

<p>Interestingly, a <em>Java server</em> doing this works:</p>
<pre><code> DataOutputStream dataOutputStream = new DataOutputStream(socket.getOutputStream());
StringBuilder outputMessage = new StringBuilder("Some output");
dataOutputStream.writeUTF(outputMessage.toString());
dataOutputStream.flush();
</code></pre>
<p>EDIT</p>
<p>This is received from the working Java server. The "bytearr" contains 100 bytes that I am using for my message and 100 bytes that are 0 (they come after my message). The "chararr" correctly sees the first 100 bytes as something meaningful and the last 200 bytes as '\u0000':

<p>This is received form the non-working C# server. It seems to start <strong>two bytes in</strong> compared to the correct version and also it's "chararr" contains only thousands of '\u0000':

D3 join() only renders 'update' while doesn't show 'enter' elements
|
<p>I tried to update an array of circles from the static positions
to dynamic force layout positions.</p>
<p>I tried to apply different colors for the circles within 'update' range
and apply another color to the new circles added from the new data.</p>
<p>however, newly added data nodes are not rendered for some reason.</p>
<p>Can anyone help me?</p>
<p>My update pattern is as below.
<br></p>
<p>1.Initial Data Binding</p>
<pre><code>let svg = d3.select('.graph')
.attr('width',width)
.attr('height',height)
svg.selectAll('circles').data(randoms)
.join('circle')
.attr('cx',d=>Math.random()*600)
.attr('cy',d=>Math.random()*600)
.attr('r',5)
</code></pre>
<p>2.Update Data binding</p>
<pre><code>let simulation = d3.forceSimulation(randoms2)
.force('x', d3.forceX().x(function(d,i) {
if(i%2==0){
return 10;
}
else{
return 20
}
}))
.force('collision', d3.forceCollide().radius(function(d) {
return 1
}))
.on('tick',ticked)
function ticked(){
d3.selectAll('circle')
.data(randoms2)
.join( enter =>enter.append('circle')
.attr("fill", "green")
.attr('cx', function(d) {return d.x})
.attr('cy', function(d) {return d.y})
.attr('r',5),
update => update
.attr("fill", "red"),
exit => exit.remove()
)
.transition().duration(100)
.attr('cx', function(d) {return d.x})
.attr('cy', function(d) {return d.y})
}
</code></pre>
<p>It only shows the updated circles.</p>
<p>the complete code is in the following link.</p>

How to re render sub component on prop change with redux?
|
<p>I have a react native app using redux and immutable js. When i dispatch an action from my main screen, it goes through my actions, to my reducer and then back to my container, however, the view doesn't update and componentWillReceieveProps is never called. Furthermore, the main screen is a list whose items are sub components <strong>Item</strong>. Here's the relevant code for the issue, if you want to see more let me know.</p>
<p>Render the row with the data:</p>
<pre><code>renderRow(rowData) {
return (
<Item item={ rowData } likePostEvent={this.props.likePostEvent} user={ this.props.user } removable={ this.props.connected } />
)
}
</code></pre>
<p>The part of Item.js which dispatches an action, and shows the result:</p>
<pre><code><View style={{flex: 1, justifyContent:'center', alignItems: 'center'}}>
<TouchableOpacity onPress={ this.changeStatus.bind(this, "up") }>
<Image source={require('../img/up-arrow.png')} style={s.upDownArrow} />
</TouchableOpacity>
<Text style={[s.cardText,{fontSize:16,padding:2}]}>
{ this.props.item.starCount }
</Text>
<TouchableOpacity onPress={ this.changeStatus.bind(this, "down") }>
<Image source={require('../img/up-arrow.png')} style={[s.upDownArrow,{transform: [{rotate: '180deg'}]}]} />
</TouchableOpacity>
</View>
</code></pre>
<p>The action dispatched goes to firebase, which has an onChange handler that dispatches another action.</p>
<p>The reducer:</p>
<pre><code>const initialState = Map({
onlineList: [],
offlineList: [],
filteredItems: [],
connectionChecked: false,
user: ''
})
...
...
case ITEM_CHANGED:
list = state.get('onlineList')
if(state.get('onlineList').filter((e) => e.id == action.item.id).length > 0){
let index = state.get('onlineList').findIndex(item => item.id === action.item.id);
list[index] = action.item
list = list.sort((a, b) => b.time_posted - a.time_posted)
}
return state.set('onlineList', list)
.set('offlineList', list)
</code></pre>
<p>The container:</p>
<pre><code>function mapStateToProps(state) {
return {
onlineItems: state.items.get('onlineList'),
offlineItems: state.items.get('offlineList'),
filteredItems: state.items.get('filteredItems'),
connectionChecked: state.items.get('connectionChecked'),
connected: state.items.get('connected'),
user: state.login.user
}
}
</code></pre>
<p>Where I connect the onChange:</p>
<pre><code>export function getInitialState(closure_list) {
itemsRef.on('child_removed', (snapshot) => {
closure_list.removeItem(snapshot.val().id)
})
itemsRef.on('child_added', (snapshot) => {
closure_list.addItem(snapshot.val())
})
itemsRef.on('child_changed', (snapshot) => {
closure_list.itemChanged(snapshot.val())
})
connectedRef.on('value', snap => {
if (snap.val() === true) {
closure_list.goOnline()
} else {
closure_list.goOffline()
}
})
return {
type: GET_INITIAL_STATE,
connected: true
}
}
</code></pre>
<p>Calling get initial state:</p>
<pre><code>this.props.getInitialState({
addItem: this.props.addItem,
removeItem: this.props.removeItem,
goOnline: this.props.goOnline,
goOffline: this.props.goOffline,
itemChanged: this.props.itemChanged
})
</code></pre>
<p>Any suggestions are welcome, thanks so much!</p>

only one database create while using a multi-database setup

<h3>Updated the <code>DATABASE_ROUTER</code> variable in settings.py file</h3>
<pre><code>DATABASE_ROUTERS = [

<p>Now, when i do <code>python manage.py syncdb</code> i see that the tables are created for celery but there is only one database created i.e. <code>devel</code>. Why are the tables being created in the <code>devel</code> database and not in <code>celery</code> database ?</p>

insert new tag create by user into my table(database) by php
|
<p>I'm currently building a blog system and here is my question.</p>
<p>I provide several basic tags(using checkbox) for users to select.</p>
<p>In the same time user can also insert a new tag by clicking the button of NEW TAG!.</p>
<p>here is my code.</p>
<pre><code>$newestTags = 0;
$title = $_POST['blog_title'] ?? '';
$content = $_POST['blog_content'] ?? '';
$tagValue = $_POST['tags'] ?? '';
$newTagFromhtml = $_POST['inserttag'] ?? '';
$totalBlog = $pdo->query("SELECT COUNT(*) from `blog`")->fetch(PDO::FETCH_NUM)[0];
$newestBlog = intval($totalBlog) + 1;
$sql = "INSERT INTO `blog`(`blog_id`,`blog_title`,`blog_content`)
VALUES(?,?,?)";
$stmt = $pdo->prepare($sql);
$stmt->execute([
$newestBlog,
$title,
$content,
]);
$tagsInsert = "INSERT INTO `blog_tagtoblog`(`tags_ID`, `blog_ID`) VALUES (?,?)";
$tags = $pdo->prepare($tagsInsert);
foreach($tagValue as $value){
$tags->execute([
$value,
$newestBlog,
]);
}
</code></pre>
<p>and here is my table for blog and tag</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>blog_tagstoblog</th>
<th>tags_id</th>
<th>blog_id</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>1</td>
<td>22</td>
</tr>
<tr>
<td>2</td>
<td>1</td>
<td>23</td>
</tr>
<tr>
<td>3</td>
<td>2</td>
<td>22</td>
</tr>
</tbody>
</table>
</div><div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>tags_id</th>
<th>tags_desc</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>food</td>
</tr>
<tr>
<td>2</td>
<td>lunch</td>
</tr>
</tbody>
</table>
</div>
<p>also my HTML and Javascript</p>
<pre><code><p>TAGS!</p>
<?php foreach($tags as $t): ?>
<div>
<input type="checkbox" class="checkbox" name="tags[]" value="<?= $t['tags_id']?>" id="<?= $t['tags_id']?>">
<label for="<?= $t['tags_id']?>" class="form-label" id="haha"> <?= $t['tags_desc']?></label>
</div>
<? endforeach; ?>
<button class="insertNewTag">NEW TAG!</button>
</div>
<button type="submit" class="btn btn-primary">submit</button>
// javascript down below
insertNewTag.addEventListener("click", function(e) {
e.preventDefault();
input.type = "text";
input.name = "tags[]"
input.value = input.value;
spaceForNewTag.append(input);
fetch("insertArticle-api.php", {
method: 'POST',
body: fd,
}).then(res => res.json()).then(obj => {
if (obj.success || obj.tagsCheck) {
console.log(obj)
alert("OKAY!")
location.href = "articleList.php";
} else {
alert(`${obj.error}`)
}
})
})
</code></pre>
<p>and now my question is,</p>
<p>it's okay for me to insert tag that I use foreach to loop over
into tagstoblog and insert tags that created by user into table of tag.</p>
<p>But I don't know how to fetch the tags_id of newest tag created by user
and insert it into table of blog_tagstoblog.</p>
<p>It is possible to do that in one go?</p>

Importing JSON data file into graph

<p>I'm fairly new to React. </p>
<p>I am trying to import this following test json data file into my React graph. </p>
<pre><code>{

{"datetime": "", "data": [1,2,3,4]},
{"datetime": "", "data": [1,2,3,4]}

</code></pre>
<p>The x-axis is the time so it should not matter very much.
But I don't know how to read the data into the y-axis. </p>
<p>This is my Graph.js: </p>
<pre><code>import React, { Component } from 'react';

class Graph extends Component {
constructor (props) {

const now = Date.now();
this.state = {
data: []
}
}

//THIS is to add points from json
//Please don't mind the stuff here--------
//This is for another graph
var sensorSerial = this.props.match.params.sensorId

phonegap and android 2.x: Application Error: Is a directory(file:///#/ ... )
|
<p>we're just about to launch our first app and are making pretty good progress as phonegap beginners so far. (At least imho)</p>
<p>We were testing it on Android 4.2+ so far and it's running fine. I was setting up an android emulator this morning to see how it works on 2.2 and 2.3.3 devices and was a bit shocked.
It's not working at all.</p>
<p>We're working with durandal as a SPA framework and as soon as I click on a menu item I'm getting the following error:</p>
<hr />
<h3>Application Error</h3>
<p>Is a directory (file:///#/tasks)</p>
<p>[OK]</p>
<hr />
<p>When I hit ok the app closes and that's it. Here's what I found in the log so far:</p>

Loading page info into array, and cycling page info as URLs
|
<p>I;ve built a CMS that allows users to build static pages of images and text content solely for displaying on television screens throughout our building. I've completed this to the point of viewing the display with it's pages but only if I call it explicitly in the url. The problem is, I want to load by display which is stored in the URL. </p>
<p>For instance, the url now if you click on Display 3 is <code>http://local.CMSTest.com/showDisplay.php?display=3</code></p>
<p>and this calls a function using 3 as the display ID that grabs all pages with that display ID. This works, but in my html where I throw a <code>foreach</code> in there, it loads both pages associated with that display into a crammed page, half and half. So I know it's working but I need to store these pages into an array for javascript as well I believe.</p>
<p>I'm thinking there may be a way where I can load it with the first page on default and append it to the url like <code>http://local.CMSTest.com/showDisplay.php?display=3&page_id = 2</code> and then after the time is up, it can go to the next one and change the URL <code>http://local.CMSTest.com/showDisplay.php?display=3&page_id = 3</code></p>
<p>So the PHP and HTML is working at this moment:</p>
<pre><code> <div class="row top">
<?php include 'banner.php'?>
</div>
<div class="row middle" style="background-image: url(<?php echo $showDisplays['background_img']?>);">
<div class="col-lg-12">
<?if($showDisplays['panel_type_id'] == 1){?>
<div class="fullContent" style=" height: 100%; ">
<?php echo $showDisplays['content']?>
</div>
<?}?>
</div>
</div>
<div class="row bottom">
<?php include 'ticker.php';?>
</div>
<?php }?>
</code></pre>
<p>I want to try some javascript like this that will take each page from the array, replacing the following URLs with page IDs from my previous array. How can I do this properly?</p>
<pre><code><script type="text/javascript">
var Dash = {
nextIndex: 0,
dashboards: [
{url: "http://www.google.com", time: 5},
{url: "http://www.yahoo.com", time: 10},
{url: "http://www.stackoverflow.com", time: 15}
],
display: function()
{
var dashboard = Dash.dashboards[Dash.nextIndex];
frames["displayArea"].location.href = dashboard.url;
Dash.nextIndex = (Dash.nextIndex + 1) % Dash.dashboards.length;
setTimeout(Dash.display, dashboard.time * 1000);
}
};
window.onload = Dash.display;
</script>
</code></pre>
<p>UPDATE:</p>
<p>Current array</p>
<pre><code>Array ( [pageID] => 104 [page_type_id] => 1 [display_id] => 3 [slide_order] => [active] => 1 [background_img] => [panel_id] => 96 [panel_type_id] => 1 [page_id] => 104 [cont_id] => 148 [contID] => 148 [content] =>This is full content)

Problem with accessing values in Request Session that I put into
|
<p>I am fairly new to Laravel. This may have an obvious solution but I can't seem to find it so far. Therefore I am asking for help.</p>
<p><strong>Question In Short:</strong>
I use Illuminate\Http\Request session ($request->session()) to store some data I get from BigCommerce API. But I can't get them when I need the data.</p>
<p><strong>Context:</strong>
I am building a sample app/boilerplate app for BigCommerce platform using Laravel/React. I have built the app using official documentation, semi-official posts released by BigCommerce team and sample codebase provided by them as well.</p>
<p>App works fine with local credentials from a specific store because they are given as environment variables to the app. However I can't read <code>store_hash</code> (which is necessary to fetch data from BigCommerce) and <code>access token</code>. Both I have put in $request->session() object.</p>
<p>I will paste the AppController.php code below, also code is publicly available <a href="https://github.com/afgonullu/bigCommerce-app" rel="nofollow noreferrer">here</a>:</p>
<p>In the <code>makeBigCommerceAPIRequest</code> method below (as you can see my debugging efforts :)) I can get <code>$this->getAppClientId()</code>, but I can't get anything from <code>$request->session()->get('store_hash')</code> or <code>$request->session()->get('access_token')</code> which returns from <code>$this->getAccessToken($request)</code>.</p>
<p>I have tried putting store hash into a global variable, but it didn't work.</p>
<p>From everything I have experienced so far, <code>$request</code> is not working as expected.</p>
<p>Any help appriciated, thanks in advance.</p>

Accessing string from an html template class
|
<p>I'm trying to access a certain variable from another class, however I'm not able to do so. I have two buttons - the first button sets token to an html template file. The second should generate the file. The first button calls the class. The second button should call the string from the class for generation.</p>
<p>My first button is as follows:</p>
<pre><code>private void btnTemplate_Click(object sender, EventArgs e)
{
if ((txtTitle.Text == "") && (txtSku.Text == "") && (txtPrice.Text == "") && (txtDesc.Text == "") && (txtImg.Text == ""))
{
MessageBox.Show("No row selected", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
else
{
OpenFileDialog SetData = new OpenFileDialog();
SetData.Filter = "HTML|*.html;";
GlobalVar.setPath = "C:\\genHtml.html";
var result = SetData.ShowDialog();
DataSet ds = new DataSet();
if (result == DialogResult.OK)
{
string fileName = SetData.FileName;
var template = new HtmlTemplate(@SetData.FileName);
var output = template.Render(new
{
TITLE = txtTitle.Text,
SKU = txtSku.Text,
PRICE = txtPrice.Text,
DESC = txtDesc.Text,
IMAGE = txtImg.Text
});
File.WriteAllText(@GlobalVar.setPath, output);
}
}
}
</code></pre>
<p>My second button:</p>
<pre><code>private void btnGenerate_Click(object sender, EventArgs e)
{
try
{
System.Diagnostics.Process.Start(GlobalVar.setPath);
}
catch
{
MessageBox.Show("Please select a template first", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
</code></pre>
<p>I get an error with the string output. How can I call string 'output' for the second button?</p>
<p>My class is as follows:</p>
<pre><code>class HtmlTemplate
{
private string _html;
public HtmlTemplate(string templatePath)
{
using (var reader = new StreamReader(templatePath))
_html = reader.ReadToEnd();
}
public string Render(object values)
{
string output = _html;
foreach (var p in values.GetType().GetProperties())
output = output.Replace("[" + p.Name + "]", (p.GetValue(values, null) as string) ?? string.Empty);
return output;
}
}

ASHX To Serialize SQL Data To GeoJSON Format
|
<p>I am trying to build a web application that pulls data from SQL Server through an ASHX Handler, convert to a valid GeoJSON format, and display the markers on a leaflet map. I have the query to pull three fields from the SQLServer (Description, LAT, LONG). I have the ability to display GeoJSON data in Leaflet (from website documentation). What I can't figure out is how to successfully build GeoJSON data. Is there an easy way to build a GeoJSON Object using the Javascript Serializer, or is it a process I have to build in the hanlder.</p>
<p>Here is an example GeoJSON file I would like to create:</p>
<pre><code>{
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"properties": {
"name": "Placemarker 1",
"marker-color": "#0000ff",
"marker-symbol": "airport"
},
"geometry": {
"type": "Point",
"coordinates": [
-77.12911152370515,
38.79930767201779
]
}
},
{
"type": "Feature",
"properties": {
"name": "Placemarker 2",
"marker-color": "#FF0000",
"marker-symbol": "hospital"
},
"geometry": {
"type": "Point",
"coordinates": [
-7.12911152370515,
5.79930767201779
]
}
}]
}
</code></pre>
<p>Here is contents of an ASHX file that I have that currently build a simple JSON File:</p>
<pre><code>private class DataSet
{
public string description { get; set; }
public double valueLat { get; set; }
public double valueLong { get; set; }
}
public void ProcessRequest(HttpContext context)
{
List<DataSet> listResults = new List<DataSet>();
int recordCount = 0;
try
{
// Get Connection String From WEB.CONFIG
string connStr = ConfigurationManager.ConnectionStrings["myConnStr"].ConnectionString;
// Connect And Get Data
OdbcConnection sqlConn = new OdbcConnection(connStr.ToString());
OdbcCommand sqlCmd = new OdbcCommand("{call getSampleData}", sqlConn);
sqlConn.Open();
OdbcDataReader rdr = sqlCmd.ExecuteReader();
while (rdr.Read())
{
DataSet results = new DataSet();
results.description = rdr["description"].ToString();
results.valueLat = Convert.ToDouble(rdr["lat"]);
results.valueLong = Convert.ToDouble(rdr["long"]);
listResults.Add(results);
recordCount++;
}
sqlConn.Close();
}
catch (OdbcException o)
{
context.Response.Write(o.Message.ToString());
}
var result = new
{
iTotalRecords = recordCount,
aaData = listResults
};
JavaScriptSerializer js = new JavaScriptSerializer();
context.Response.Write(js.Serialize(result));
}

Parse retrieve objectId from class causes app to stop (not crash)
|
<p>I have already submitted a question on how to retrieve an objectId (<a href="https://stackoverflow.com/questions/28621309/swift-retrieve-objectid-field-causes-fatal-error">swift - retrieve objectId field causes fatal error</a>) but that seems to only apply to objects during a save because I have spent a long time (days) trying to retrieve the objectId from a saved row in a Parse cloud DB with absolutely no luck. I've mimicked the code in the Parse object retrieval documentation (<a href="https://parse.com/docs/ios_guide#objects-retrieving/iOS" rel="nofollow noreferrer">https://parse.com/docs/ios_guide#objects-retrieving/iOS</a>), using the special values provided for objectId's:</p>
<pre><code>let objectId = gameScore.objectId
</code></pre>
<p>I was getting a crash every time but now the app just stops after printing the successful login message. Here is the code and sequence of events.</p>
<p>I signup a new user (let's call him vin). </p>
<p>The signup code: </p>
<pre><code>@IBAction func signUp(sender: AnyObject) {
if countElements(self.userNameTextField.text) > 0 && countElements(self.passWordTextField.text) > 0 {
var megabyker = PFUser()
user.username = self.userNameTextField.text
user.password = self.passWordTextField.text
user.signUpInBackgroundWithBlock{
(succeeded:Bool!, error:NSError!)->Void in
if error == nil {
println("Sign Up successfull")
//associate current user for parse remote push notifications
var installation:PFInstallation = PFInstallation.currentInstallation()
installation.addUniqueObject("goride", forKey: "channels")
installation["user"] = PFUser.currentUser()
installation.saveInBackground()
//default row for allData table
//save default settings row for GUEST user
var alldata:PFObject = PFObject(className: "allData")
alldata["divvy_routes"] = "ON"
alldata["sortBy"] = "distance"
alldata["totalRides"] = 0
alldata["username"] = user.username
//self.useGuestUser = "USER"
alldata["user"] = PFUser.currentUser()
alldata.saveInBackgroundWithBlock{(success:Bool!, error:NSError!) ->Void in
if success != nil {
NSLog("%@","OK-alldata REAL data saved")
self.allDataSignUpObjectId = alldata.objectId
println("printing out objectId var in ALLDATA REAL section: ")
println(self.allDataSignUpObjectId)
self.performSegueWithIdentifier("go-to-main-menu", sender: self)
}
else
{
NSLog("%@",error)
}
}
} else {
let alert = UIAlertView()
alert.title = "Invalid Signup"
alert.message = "Sorry, a username (unique) and a password are required to create a new account."
alert.addButtonWithTitle("OK")
alert.show()
}
}
}
else
{
let alert = UIAlertView()
alert.title = "Invalid Signup"
alert.message = "Sorry, a username (unique) and a password are required to create a new account."
alert.addButtonWithTitle("OK")
alert.show()
}
}
</code></pre>
<p>The signup code works fine. It creates a new user and row in the User table and new default row in the allData table. The allData table has a user pointer column to associate it with the User table. I grab the objectId and assign it to an instance variable because I want to pass it to another viewcontroller to use:</p>
<pre><code>self.allDataSignUpObjectId = alldata.objectId
println(self.allDataSignUpObjectId)
</code></pre>
<p>And here is a screenshot of the ParseDB where you can see the row has been saved in the user table for the new user. His objectId is 9vRF8BvdlZ and the row in the allData table has an objectId of DEaj0iWZ3X. This is the objectId I am trying to get (DEaj0iWZ3X).</p>
<p>allData table:</p>
<p><img src="https://i.stack.imgur.com/pTSvO.png" alt="enter image description here"></p>
<p>Now here is the allData where the new user's default setting row is inserted and it's automatically linked to the Vin's user table:</p>
<p><img src="https://i.stack.imgur.com/qHXhL.png" alt="enter image description here"></p>
<p>I then go to the Settings view controller and Save as the newly created user:</p>
<pre><code> @IBAction func updateSettings(sender: AnyObject) {
var alldata:PFObject = PFObject(className:"allData")
var user = PFUser.currentUser()
var query = PFQuery(className:"allData")
query.whereKey("user", equalTo: user)
var id = allDataPass
println(id)
query.getObjectInBackgroundWithId(id) {
(alldata: PFObject!, error: NSError!) -> Void in
if error != nil {
NSLog("%@", error)
} else {
alldata["routes"] = self.RoutesSetting
alldata.saveInBackground()
}
}
}
</code></pre>
<p>It saves with no problems and the updated time in the row updates. </p>
<p>But when I logback in as Vin (after resetting the contents and settings on the simulator to get a fresh start), I get to LOGIN but it just stops (not crash, just stops and won't get past the login screen).</p>
<p>Here's the console printout:</p>
<pre><code>2015-02-26 22:19:01.732 MegaByke[51906:6996084] Location Services Not Determined, must ask user

<p>Here is my login code:</p>

case NotReachable.value:
var alert = UIAlertView(title: "No Internet Connection", message: "In order to login, you must have internet connection. You can still login as a Guest", delegate: nil, cancelButtonTitle: "Dismiss")
alert.show()
default:
if countElements(self.userNameTextField.text) > 0 && countElements(self.passWordTextField.text) > 0 {

var query = PFQuery(className:"allData")
query.whereKey("user", equalTo: user)
// Retrieve the most recent one
query.orderByDescending("createdAt")
query.limit = 1;
//assign objectId
var alldata = PFObject(className:"allData")
println("objectId preFETCH")
println(alldata.objectId)
//refresh object
alldata.fetch()
let id = alldata.objectId
println("objectId postFETCH")
println(id)
query.getObjectInBackgroundWithId(id) {

if error == nil {

NSLog("%@", alldata)
self.performSegueWithIdentifier("go-to-main-menu", sender: self)
} else {
NSLog("%@", error)
}
}
}
else { // Log details of the failure
NSLog("Error: %@ %@", error, error.userInfo!)
}
}
}
else{
println(user)
let alert = UIAlertView()
alert.title = "Invalid Login"
alert.message = "Sorry, that username and/or password is incorrect. Please enter a valid combination."
alert.addButtonWithTitle("OK")
alert.show()
println("Login failed")
}
}
}
</code></pre>
<p>The println that's supposed to occur after the fetch never gets to the console so I'm assuming I have not successfully retrieved the objectId. I have also checked Parse's user forum and no help there. </p>

Boost.Spirit: combining preparsing with keyword parser and with Nabialek trick
|
<p>I have the input in the json-like form </p>
<pre><code>{
type: "name",
value: <json_value>,
}
</code></pre>
<p>Type name can be one of "int1", "int2a", "int2b" (of course, I simplify the real situation to provide the minimal relevant code). </p>
<p>The value always confirms to JSON syntax but also depends on type name. The possible cases are:</p>
<pre><code>type: int1 => expected value: <number>
type: int2a => expected value: [ <number>, <number> ]
type: int2b => expected value: [ <number>, <number> ]
</code></pre>
<p>I need to parse input into the following data types:</p>
<pre><code>struct int_1 { int i1; };
struct int_2a { int i1, i2; };
struct int_2b { int i1, i2; };
using any_value = boost::variant<int_1, int_2a, int_2b>;
struct data { std::string type; any_value value; };
</code></pre>
<p>I combined keyword parser with Nabialek trick. I create symbols table and store the pointers to the <strong>int_1</strong>, <strong>int_2a</strong> and <strong>int_2b</strong> parsers into it:</p>
<pre><code>using value_rule_type = qi::rule<It, any_value (), Skipper>;
qi::symbols<char, value_rule_type *> value_selector;
qi::rule<It, int_1 (), Skipper> int1_parser;
qi::rule<It, int_2a (), Skipper> int2a_parser;
qi::rule<It, int_2b (), Skipper> int2b_parser;
value_rule_type int1_rule, int2a_rule, int2b_rule;
int1_parser = int_ ;
int2a_parser = '[' >> int_ >> ',' >> int_ >> ']';
int2b_parser = '[' >> int_ >> ',' >> int_ >> ']';
int1_rule = int1_parser;
int2a_rule = int2a_parser;
int2b_rule = int2b_parser;
value_selector.add
( "\"int1\"", &int1_rule )
("\"int2a\"", &int2a_rule )
("\"int2b\"", &int2b_rule )
;
</code></pre>
<p>I use keyword parser to parse the outer <strong>data</strong> structure:</p>
<pre><code>data_
%= eps [ _a = px::val (nullptr) ]
> '{' > (
kwd ( lit ("\"type\"" ) ) [ ':' >> parsed_type_ (_a) >> ',' ]
/ kwd ( lit ("\"value\"") ) [ ':' >> value_ (_a) >> ',' ]
) > '}'
;
</code></pre>
<p>parsed_type_ rule here do a look up into the symbol table for the type name and sets the local variable of <strong>data</strong> rule to the found rule pointer.</p>
<pre><code>parsed_type_ %= raw[value_selector [ _r1 = _1 ]];
</code></pre>
<p>And value_ rule has the usual form for the Nabialek trick:</p>
<pre><code>value_ = lazy (*_r1);
</code></pre>
<p>This parser works just fine (<a href="http://coliru.stacked-crooked.com/a/03622920a1e4f4c7" rel="nofollow">live demo</a>)... except for the case when value is passed before the type name:</p>
<pre><code>{
value: <json_value>,
type: "name",
}
</code></pre>
<p>As we have NULL in the stored pointer to the rule, and the parser for "type" field did not run yet, the program crashes during the parsing the "value" field.</p>
<p>I'd like to fix this case. If the value field follows the type name field, I'd like the current parser logic applied (as in live demo). </p>
<p>If value precedes the type key, I'd like to pre-parse value field with the json parser (just to find the end-boundary of that field) and to store that field in the form of iterator range into some local variable. After the parser got "type" field, I'd like to start the specific parser - int1_rule, int2a_rule or int2b_rule over stored range.</p>
<p>So, the expression </p>
<pre><code>value_ = lazy (*_r1);
</code></pre>
<p>should probably be changed the something like: </p>
<pre><code>if (_r1 == NULL) {
<parse json value>
<store raw range into local variable>
} else {
lazy (*_r1);
}
</code></pre>
<p>and expression</p>
<pre><code>parsed_type_ %= raw[value_selector [ _r1 = _1 ]];
</code></pre>
<p>should be extended with:</p>
<pre><code>if (has stored range) parse it with lazy (*_r1);
</code></pre>
<p>Unfortunately I have no idea how to implement it or it is possible at all.</p>
<p>I include simplified JSON parser found on stackoverflow into my live demo for the convenience.</p>
<p>The question: Is it possible at all with spirit? If yes, how it can be done? </p>

AJAX call not triggered on show.bs.modal
|
<p>I have a button which is supposed to trigger a modal with a contact form. Part of the <code>show.bs.modal</code> function is an AJAX call to my DB to get some file details which are then meant to be shown in the modal-body.</p>
<p>The problem is that the modal does indeed open, but with no <code>modal-body</code> content, which means that the JavaScript code to trigger to the AJAX call is not working. I do not see any network activity in the browser debug menu, no call to the PHP file, and even an <code>alert</code> on top of the JS code telling me that that a button was pressed is not triggered. It seems like the whole JS code is circumvented, yet the modal still shows.</p>
<p>The same code works in another project, anyone has any idea as to why this is happening?</p>
<p>Button:</p>
<pre><code><div class="card-footer bg-light text-center">
<button id="modal_btn" name="modal_btn" type="button" class="btn bg-teal-400" data-toggle="modal" data-target="#modal_contact_form" data-imgid="'.$row['image_id'].'" data-keyboard="true">

<p>Modal:</p>

Theme Files getting include in .ics downloaded file

Im using the idea and ICS.php file from <a href="https://gist.github.com/jakebellacera/635416" rel="nofollow noreferrer">https://gist.github.com/jakebellacera/635416</a> that is a old post.</p>

How to pass Token of the first request response to the second request header, using Axios in an Ionic React app (2 Post Requests)
|
<p>I want to register a user and save his partner's data at the same time. The first axios request creates the user and returns a token. I need the token as a header of the second request.
I have implemented as following 'doCreateAccount' but it is not working. It performs only the first request .post("xx/register", userData)</p>
<p><strong>Can someone tell me how to make two axios requests, where the second one uses the token taken from the response of the first one?</strong></p>
<p>The component:</p>
<pre><code>import React from "react";
import { useHistory } from "react-router-dom";
import { useState } from "react";
import axios from "axios";
const CreateAccount: React.FC = () => {
const history = useHistory();
const doCreateAccount = () => {
const userData = {
eMail: getValues("email"),
password: getValues("password"),
};
const partnerData = {
cardType: "6",
firstName: getValues("partnerFirstName"),
lastName: getValues("partnerLastName"),
};
axios
.post("/xx/register", userData)
.then((firstResponse) => {
localStorage.setItem("user", JSON.stringify(firstResponse.data));
axios
.post("/xx/cards", partnerData, {
headers: firstResponse.data.token,
})
.then((secondResponse) => {
history.push("/homePage");
return secondResponse.data;
})
.catch((error) => {
console.log("sth happened in cards request");
setIserror(true);
});
})
.catch((error) => {
console.log("sth happened in register");
setIserror(true);
});
};

Python 3: How to generate a table from a nested list as input
|
<p>So, I've got the following nested list (which I've parsed from an Nmap XML output file). It's basically a list of IP addresses, and all their open ports:</p>
<pre><code>[['192.168.23.78', ['53', '88', '135', '139', '389', '445', '3389']],
['192.168.27.243', ['135', '139', '445', '3389', '5800', '5900']],
['192.168.99.164', ['135', '139', '445', '3389', '5800', '5900']],
['192.168.228.211', ['80']],
['192.168.171.74', ['135', '139', '445', '3389', '5800', '5900']]]
</code></pre>
<p>I would like to create a table from this data, where each first item (all IP addresses) are printed as rows. I then wish to iterate over each second item (a list of all ports per IP address), and count each unique port number. I wish this new counted unique list of ports to be printed as column headers of my table. My empty table should then roughly look like this:</p>
<pre><code> 53 80 88 135 139 389 445 3389 5800 5900
192.168.23.78
192.168.27.243
192.168.99.164
192.168.228.211
192.168.171.74
</code></pre>
<p>And then I wish to place X's in each correct cell for each IP address that has a given open port, like so:</p>
<pre><code> 53 80 88 135 139 389 445 3389 5800 5900
192.168.23.78 X X X X X X
192.168.27.243 X X X X X X
192.168.99.164 X X X X X X
192.168.228.211 X
192.168.171.74 X X X X X X
</code></pre>
<p>How would I do this with my data set?</p>
<p>I'm a total newbie, but I could likely figure out how to iterate over all the port numbers and get a unique port list. But I have absolutely not clue how to then plot X's on the table, in the correct cells</p>
<p>This is my code so far:</p>
<pre class="lang-py prettyprint-override"><code>#!/usr/bin/env python
from pprint import pprint
import xml.etree.ElementTree as ET
def loopy(item):
for port in host.findall('ports/port'):
if port.get('protocol') == "tcp":
portid = port.get('portid')
for state in port.findall('state'):
if state.get('state') == "open":
if item == "address":
list_addr.append(addr)
return
elif item == "portid":
list_portid.append(portid)
root = ET.parse('scan5.xml').getroot()
result = []
for host in root.findall('host'):
list_portid = []
list_addr = []
address = host.find('address')
addr = address.get('addr')
loopy("address")
loopy("portid")
if list_addr:
result.append([list_addr[0], list_portid])
pprint(result)
</code></pre>
<p>My nested list is in now <code>result</code>, but I have no clue how to create a table from this.</p>
<p>So far my code only produces the raw list:</p>
<pre><code>[['10.133.23.78', ['53', '88', '135', '139', '389', '445', '3389']],
['10.133.27.243', ['135', '139', '445', '3389', '5800', '5900']],
['10.133.99.164', ['135', '139', '445', '3389', '5800', '5900']],
['10.135.228.211', ['80']],
['10.133.171.74', ['135', '139', '445', '3389', '5800', '5900']]]

<p><a href="https://stackoverflow.com/questions/55423493/how-to-get-date-part-query-to-hit-index">How to get date_part query to hit index?</a></p>
<p>When executing the following query, it hits a compound index I created on the datelocal, views, impressions, gender, agegroup fields:</p>
<pre><code>SELECT date_part('hour', datelocal) AS hour
, SUM(views) FILTER (WHERE gender = 'male') AS male
, SUM(views) FILTER (WHERE gender = 'female') AS female
FROM reportimpression
WHERE datelocal >= '2019-02-01' AND datelocal < '2019-03-01'
GROUP BY 1
ORDER BY 1;
</code></pre>
<p>However, I'd like to be able to also filter this query down based on additional clauses in the WHERE, for example:</p>
<pre><code>SELECT date_part('hour', datelocal) AS hour
, SUM(views) FILTER (WHERE gender = 'male') AS male
, SUM(views) FILTER (WHERE gender = 'female') AS female
FROM reportimpression
WHERE datelocal >= '2019-02-01' AND datelocal < '2019-03-01'
AND network LIKE '%'
GROUP BY 1
ORDER BY 1;
</code></pre>
<p>This second query is MUCH slower than the first, although it should be operating on far fewer records, in addition to the fact that it doesn't hit my index.</p>
<p>Table schema:</p>
<pre><code>CREATE TABLE reportimpression (
datelocal timestamp without time zone,
devicename text,
network text,
sitecode text,
advertisername text,
mediafilename text,
gender text,
agegroup text,
views integer,
impressions integer,
dwelltime numeric
);

<p>Do I need to create additional indexes, tweak my SELECT, or something else entirely?</p>

Order of groups in R dplyr group_by function
|
<p>I'm using the <code>dplyr::group_by()</code> function in order to summarise some data. Let's assume the following dataframe:</p>
<pre><code>set.seed(1)
df <- data.frame(ans = sample(c("Yes", "No"), size = 10, replace = TRUE),
sex = factor(sample(c("Male", "Female"), size = 10, replace = TRUE)),
age = sample(c(10, 20, 30), size = 10, replace = TRUE),
res = rnorm(10, mean = 1, sd = 10))
</code></pre>
<p>The output after the summary is as follows:</p>
<pre><code>df %>% dplyr::group_by(ans, sex, age) %>% summarise(mean_ans = mean(res, na.rm = TRUE))
# A tibble: 9 x 4
# Groups: ans, sex [?]
ans sex age mean_ans
<fct> <fct> <dbl> <dbl>
1 No Female 10 8.82
2 No Female 20 6.09
3 No Male 10 9.21
4 No Male 20 10.2
5 No Male 30 -18.9
6 Yes Female 10 6.94
7 Yes Female 20 7.20
8 Yes Male 10 0.838
9 Yes Male 30 0.551
</code></pre>
<p>It seems that <code>group_by()</code> lists the groups alphabetically (conflicts resolved by the next grouping variable). What about the <code>age</code> variable - why isn't it in some order (e.g. 10, 20, 30)?</p>
<p>If I use <code>age</code> as the first grouping variable I get a dataframe that is sorted by all three grouping variables:</p>
<pre><code>dplyr::group_by(age, sex, ans) %>% summarise(mean_ans = mean(res, na.rm = TRUE))
# A tibble: 9 x 4
# Groups: age, sex [?]
age sex ans mean_ans
<dbl> <fct> <fct> <dbl>
1 10 Female No 8.82
2 10 Female Yes 6.94
3 10 Male No 9.21
4 10 Male Yes 0.838
5 20 Female No 6.09
6 20 Female Yes 7.20
7 20 Male No 10.2
8 30 Male No -18.9
9 30 Male Yes 0.551
</code></pre>
<p>Is it always the case that <code>group_by()</code> returns a data frame ordered alphabetically by character and factor variables? According to <a href="https://github.com/tidyverse/dplyr/issues/2159" rel="nofollow noreferrer">this discussion</a> it is the case but since the discussion took place in 2016 I'd like to know whether the conclusions are still valid. </p>
<p><strong>EDIT</strong>: I ran the original data frame with 100 rows so that all 12 groups (2*2*3) are created. It seems obvious that the data frame is sorted (including numerical columns). However, I'm not satisfied with my 'investigation' - is there a general-case proof (my simulation is one out of many). Do you know any counterexamples?</p>
