// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row

int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);

Toast.LENGTH_LONG).show();
}
} catch (Exception e) {

<pre><code>$rooms[] = array(array("paxType" => "Adult"), array("paxType" => "Adult"));
</code></pre>
<p>Example 2 rooms ( one room is with two adults and the second room si with 2 adults an
one child</p>
<pre><code>$rooms[] = array(array("paxType" => "Adult"), array("paxType" => "Adult"));
$rooms[] = array(array("paxType" => "Adult"), array("paxType" => "Adult"), array("paxType" =>"Child", "age" => 8));
</code></pre>
<p>The variables that i receive from the form are as below:</p>
<pre><code>$City= $_POST['City']; - text
$CheckIN= $_POST['CheckIN']; - text (date)
$CheckOUT= $_POST['CheckOUT']; - text (date)
$Rooms= $_POST['Rooms']; - selector (1,2,3,4,5,6)
$Adults= $_POST['Adults']; - selector (1,2,3,4,5,6)
$Childs= $_POST['Childs']; - selector (0,1,2,3,4,5)
</code></pre>
<p>Form is workink fine for text and date input fields.
How can i translate the html form request to get into the a bove look like php arrays.
Thank you for your time.</p>
<p>Entire code is:</p>
<pre><code>// create SOAP client object
$client = new SoapClient("http://www.bookingassist.ro/test/book.wsdl", array('trace' => 1));
try {

Django cumulative value displayed in template
|
<p>I’m new to Django and Python and have been plugging through Python Crash Course. I have finished that and now have been making my own Django project, adding some extra bits in.</p>
<p>Currently, I have a table of entries from my model which I am displaying with a template, each entry in the table has a time and some other data. What I would like is the value for the cumulative time in a column, next to each entries time ie</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>Lesson</th>
<th>Lesson time</th>
<th>cumulative time</th>
</tr>
</thead>
<tbody>
<tr>
<td>Lesson1</td>
<td>0.5</td>
<td>0.5</td>
</tr>
<tr>
<td>Lesson2</td>
<td>1</td>
<td>1.5</td>
</tr>
<tr>
<td>Lesson3</td>
<td>1.3</td>
<td>2.8</td>
</tr>
</tbody>
</table>
</div>
<p>I’m just really stuck on how to get this done, I have looked at lot’s of stack overflow and tried various ways that I just can’t get to work correctly. Looking at other examples they use annotate() and cumsum, but I’ve not been able to get that to work. I’ve done count and sum of other values but this has got me stuck. I think I need to loop over it in my view, but not sure how to associate each value to a cumulative time.</p>
<p>Any help would be greatly received.
Also, sorry this isn't very well written or succinct, programming doesn't come naturally to me.</p>

Using Factory with DryIoc and getting object by string
|
<p>I am just testing invertion control using DryIoc library. Please check above to get the picture.</p>
<p>I have that factory class:</p>
<pre><code> 'FactoryConnections using IoC Dry
Public Class FactoryConnections
Private Shared ReadOnly Container As Container
Shared Sub New()
Container = New Container()
With Container
.Register(Of ISftp, Sftp)
.Register(Of ISaop, Soap)
'.Register(Of IFtp, Ftp)
.Register(Of IFtp, Ftp)(serviceKey:= "some string value")
End With
End Sub
Public Shared Function ResolveService(Of T As IProtocol)(value As Iprotocol) As T
Return Container.Resolve(Of T)
End Function
End Class
</code></pre>
<p>Just shortly according to invertion:</p>
<pre><code>A -> Y (A uses Y)
A -> Interface B -> Y (in this case A doesn't know about Y)
</code></pre>
<p>we can read my solution the same:</p>
<pre><code>A -> IFtp -> Ftp
</code></pre>
<p>Therefore instead of getting directly object like: Ftp, Sftp or Soap code should ask factory to get one of them based on the interface therefore calling point doesn't know exactly what concrete object is using but it knows who implements that - that's at elast my understanding. Therefore i could ask calling them via interfaces. This is what i am trying to do however from string value (project related requirment). </p>
<pre><code>Dim myProtocol As String = "IFtp"
</code></pre>
<p>And as mentioned having that i want to get proper object from my factory in this case i should get New instance of Ftp right?</p>
<p><em>Note that parent interface for IFtp, ISoap, ISftp is IProtocol</em> </p>
<p>I was trying like this:</p>
<pre><code>Dim myProtocol As String = "IFtp"
Dim itemprotocol As type = Type.GetType(myProtocol)
Dim realprotocolobject = FactoryConnections.ResolveService(TypeOf(itemprotocol))
</code></pre>
<p>and also tried like this:</p>
<pre><code>Dim myProtocol As String = "IFtp"
Dim realprotocolobject = FactoryConnections.ResolveService(Of IProtocol)(myProtocol)
</code></pre>
<p>What's wrong, What am i doing wrong?</p>
<p>One more thing: what is the diffrence between those lines?
(just saw this serviceKey somwhere..)</p>
<pre><code>.Register(Of IFtp, Ftp)
.Register(Of IFtp, Ftp)(serviceKey:= "some string value")
</code></pre>

Cesar decryption. How to deal with non-alphanumerical chars | JS
|
<p>Build a function which takes an encrypted string as argument. it's a Cesar encryption. Like: encrypted character + 5 (or whatever number).</p>
<p><strong>Problem: The encrypted string contains non-alphanumeric chars like " " or "!".</strong></p>
<p>I build a very verbose function which is attached below for completion. <strong>The main part to solve the above mentioned problem is:</strong></p>
<pre><code> let z = /[^A-^Z]/g;
if (strIn.search(z) !== 0) {
let n = strIn.search(z);
wordArr.splice(n, 0, strIn[n]);
</code></pre>
<p><code>strIn</code> is the uppercase version of the input string (the encrypted string)
<code>wordArr</code> is the decrypted version <strong>without</strong> non alphanumeric chars.</p>
<p>I tried to loop like this:</p>
<pre><code> for (var i = 0; i < strIn.length; i++) {
if (strIn.search(z) !== 0) {
let n = strIn.search(z);
wordArr.splice(n, 0, strIn[n]);
}
}
</code></pre>
<p>I also tried a while loop. Similar successless.
I also tried to map. But than console throws: </p>
<pre><code> strIn.map is not a function
</code></pre>
<p><strong>Could anyone explain this behavior and give me just a hint how to solve this problem.
1.) Using a loop
2.) Using something better if possible</strong></p>
<p>Here my verbose code for reference or whatever:</p>
<pre><code>function rot13(str) {
let upper = str.toUpperCase().split("");
let index = [];
let decode = [];
const alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
for (var i = 0; i < upper.length; i++) {
if (alpha.indexOf(upper[i]) === -1) {
index.push(upper[i]);
} else if (alpha.indexOf(upper[i]) !== -1) {
index.push(alpha.indexOf(upper[i]));
}
}
console.log("index: " + index);
let elem = index.map(function(a, b) {
if (a === 13) {
return a - 13;
} else if (a + 13 <= 26) {
return a + 13;
} else if (a + 13 > 26) {
return a - 13;
}
});
console.log("elem :" + elem);
for (var j = 0; j < elem.length; j++) {
decode.push(alpha[elem[j]]);
}
let word = decode.join("");
let strIn = upper.join("");
console.log("strIn: " + strIn);
let z = /[^A-^Z]/g;
// let z = /[\!]/g;
let wordArr = Array.from(word);
if (strIn.search(z) !== 0) {
let n = strIn.search(z);
wordArr.splice(n, 0, strIn[n]);
}
console.log("wordArr: " + wordArr);
console.log(wordArr.join(""));
console.log(strIn.search(z));
}
rot13("SERR CVMMN!");

React setState not merging all changes
|
<h2>EDIT - I can't vote for my own answer at the moment but this turned out to be a reference/immutability issue - see <a href="https://stackoverflow.com/a/60189228/11602055">https://stackoverflow.com/a/60189228/11602055</a></h2>
<p>this one has me completely stumped!</p>
<p>I'm getting some data from my server and applying it to my state, but some of the properties I'm applying to the state don't migrate to the state after setState has completed...</p>
<p>I've tried everything I can think of regarding this, I'm reading the final state as part of the callback from setState to ensure I'm getting the state after setState has completed so it's nothing to do with setState being Async in nature.</p>
<p>Have attempted the following -</p>
<ul>
<li>use a blank object, save new props to that object and then return that.</li>
<li>apply each property one at a time in separate setState calls inside an outer loop on the keys</li>
<li>return Object.assign({},this.state,data);</li>
<li>return {...data};</li>
<li>return {...this.state,...data};</li>
<li>await setState(...);</li>

Dissolve/combine an Array based on attributes
|
<p>I have an array that i made by combining two other arrays. The new array has all the data from the original arrays joined based on an attribute (id). I would like to make a new array that combines all the attribute (id)values into one string without duplicating the data. The data has many different (Attribute and AttributeValue) pairs but the rest of the data is the same. here is a two examples of the data that come out:</p>
<pre><code> 0:

AccessionID: "UWAR_007_Test"
Attribute: "Object Type"
AttributeValue: "Glass"
BoxNumber: "2000"
CatalogDate: null
Cataloger: "rkirkwo2@uwyo.edu"
FSNumber: null
FreeformValue: null
ProjectNumber: "#154 WAPA"
SiteID: "00ABCD"
Units: null
1:

Python - Newspaper Library - Why is it missing sizable portions of articles?
|
<p>I'm using the newspaper library, V. 2.7 found <a href="http://newspaper.readthedocs.io/en/latest/" rel="nofollow">here</a>. </p>
<p>When I download, parse, and print the text, it gives me a much smaller portion of the article than exists in reality. Why is this? Is there any way to fix this? </p>
<p>Here is my code:</p>
<pre><code>from newspaper import Article
url = "http://www.nytimes.com/2010/10/07/us/politics/07manchin.html"
article_object = Article(url, language = 'en')
article_object.download()
article_object.parse()
article_object.text
</code></pre>
<p>If you look at what it prints out, and <strong><a href="http://www.nytimes.com/2010/10/07/us/politics/07manchin.html" rel="nofollow">compares with the actual article online</a></strong>, one finds that the article.text skips over the first 7-8 paragraphs of the actual article. Any way to make sure the "full" article is captured?</p>
<p>Here's the output of article_object.text:</p>
<blockquote>
<p>u'The national Republican Party has smelled blood and is spending
millions on television ads here as part of its drive to retake the
Senate. One new ad shows men in baseball caps predicting that Mr.
Manchin will transform into \u201cWashington Joe,\u201d declaring,
\u201cWe\u2019ve got to stop Obama.\u201d\n\nPhoto\n\nMr. Manchin
thought he had punched all the right buttons in this state with a
Democratic majority but conservative values. He won his second term as
governor in 2008 with 70 percent of the vote and has garnered praise
for fiscal responsibility; even Mr. Raese calls him a good governor.
He has been endorsed by the Chamber of Commerce, the National Rifle
Association and both the coal industry and the mine workers.\n\nMr.
Manchin is highlighting his conservative credentials and record of
independence and he has accused his opponent of waging a campaign of
\u201cfear and smear.\u201d But the anti-Obama message appears to be
resonating with some residents \u2014 perhaps the same voters who gave
the state to Senator John McCain and President Bush in the last three
presidential elections.\n\n\u201cManchin has been a great governor,
but I\u2019m going to vote for Raese,\u201d said Jeff Whittington, 41,
a tire distributor in Charleston. \u201cI think Manchin will get to
the Senate and be a rubber stamp for Obama,\u201d he said, repeating
Mr. Raese\u2019s message almost word for word.\n\nIn a state where
coal is seen as the fount of prosperity, Mr. Raese has seized on what
he calls ambiguous statements by Mr. Manchin on proposals for a
cap-and-trade system to reduce greenhouse gases. Mr. Manchin now
speaks clearly on the issue: he is firmly against cap-and-trade and a
carbon tax, he emphasized in the interview.\n\nOn Wednesday, Mr.
Manchin had an opportunity to underscore his support for coal and to
distance himself from the president. With the head of the coal
producers\u2019 association at his side in the state Capitol, he
announced that the state was suing two federal agencies, seeking to
reverse the stricter controls on mountain-top coal mining adopted in
2009 by the Obama administration.\n\nAdvertisement Continue reading
the main story\n\nDiscussing the suit against the Environmental
Protection Agency and the Army Corps of Engineers, Mr. Manchin said
that the more stringent procedures were unlawful and had harmed the
state by slowing new mining projects to a trickle, and he accused the
Obama administration of trying \u201cto destroy our coal industry and
way of life.\u201d\n\nThe E.P.A. responded that its actions were
legally and scientifically sound.\n\nMr. Manchin, independent experts
and even the West Virginia Coal Association have taken exception to a
Raese ad accusing Mr. Manchin of passing a state law that
\u201celiminates 25 percent of coal usage in our power
plants.\u201d\n\nIn fact, the law calls for progress in new energy
technologies that include cleaner coal, and it had the support of the
industry.\n\nMr. Raese has also lambasted the governor for past
statements welcoming the Obama health plan; Mr. Manchin says that some
core elements of the plan, like protecting children\u2019s coverage,
are good but that others should be repealed. Mr. Raese calls the
health plan \u201cpure, unadulterated socialism\u201d that should be
discarded entirely, a message that appeals to many small-business
owners.\n\nPhoto\n\nMr. Raese is a brawny and self-confident man who
has run unsuccessfully for the Senate and for governor before and now
feels currents flowing his way. \u201cHow do you put together a
business plan when you have Obamacare facing you, when you\u2019ve got
cap-and-trade facing you?\u201d he asked in an interview at the
Republican office in Morgantown, his home base.\n\nMr. Raese runs
limestone mines and a steel-fabrication company and is part owner of a
radio network and a newspaper. He has at least three homes around the
country, and his wife lives in their home in Palm Beach, Fla., while
he has kept his residence in West Virginia.\n\nWhile Mr. Raese\u2019s
anti-Washington message has wide appeal, his unequivocal support for
Nafta and free trade and his opposition to unions may not help him in
a state with a blue-collar heritage. Mr. Manchin\u2019s campaign has
run ads featuring Mr. Raese boasting about his inherited wealth and
highlighting his opposition to minimum wages and other worker
protections.\n\nIn interviews across the state, some residents said
that while Mr. Raese can seem arrogant, they admired his record of
creating jobs and were ready to send a new face to Washington rather
than elect a man they see as a career politician.\n\nAdvertisement
Continue reading the main story\n\nThe only polls published so far
were automated \u2014 done without personal interviews \u2014 and are
not widely accepted as reliable. But private polling by both camps
indicates an unexpectedly close race.\n\nFord Frances, 53, a lawyer in
Charleston, said he likes Mr. Manchin as governor \u2014 Mr. Manchin
will retain his job if he loses the Senate race \u2014 but that he is
leaning toward voting for Mr. Raese because he worries about a
skyrocketing federal deficit and thinks government has too big a role
in the economy.\n\nOthers, including Cheryl Bonner, 64, of Fairmont,
said they thought it was unfair to paint Mr. Manchin with the excesses
of Washington. \u201cHe\u2019s been for West Virginia, and I\u2019m
leaning toward voting for him,\u201d said Ms. Bonner, who had to start
working again, as a store clerk, because her and her husband\u2019s
Social Security and pension checks did not cover the bills. She hopes
that retirees will be protected, whoever wins, she said.\n\nSome
residents said Mr. Manchin was just unlucky to be running for national
office this year. \u201cProbably at any other time he\u2019d have
gotten my vote,\u201d said a 51-year-old credit analyst in Charleston,
an economic conservative who voted for Mr. Manchin in 2008 but is
troubled by the administration\u2019s economic
policies.\n\n\u201cPutting him in that Senate seat would enhance the
Democrats\u2019 position,\u201d said the man, who declined to give his
name because his company has dealings with the governor\u2019s office.
\u201cWe\u2019d rather keep him here as governor.\u201d'</p>

Using Future with ExecutorService
|
<p>I need to execute two tasks in parallel and wait for them to complete. Also I need the result from the second task, for that I am using <code>Future</code>. </p>
<p>My question is that DO I need <code>executor.awaitTermination</code> to join the tasks or <code>Future.get()</code> will take care of it. Also is there a better way to achieve this with Java 8?</p>
<pre><code>public class Test {
public static void main(String[] args) {
test();
System.out.println("Exiting Main");
}
public static void test() {
System.out.println("In Test");
ExecutorService executor = Executors.newFixedThreadPool(2);
executor.submit(() -> {
for(int i = 0 ; i< 5 ; i++) {
System.out.print("["+i+"]");
try {
Thread.sleep(1000);
} catch (Exception e) {e.printStackTrace();}
}
});
Future<String> result = executor.submit(() -> {
StringBuilder builder = new StringBuilder();
for(int i = 0 ; i< 10 ; i++) {
System.out.print("("+i+")");
try {
Thread.sleep(1000);
} catch (Exception e) {e.printStackTrace();}
builder.append(i);
}
return builder.toString();
});
System.out.println("shutdown");
executor.shutdown();
// DO I need this code : START

try {
executor.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);

PHP for loop stops after the first iteration
|
<p>For a project I am trying to do something in PHP. It requires a <code>for</code> loop and houses one as well. The <code>for</code> loop inside the initial loop functions as expected. It loops through the variables and stops once <code>$i</code> is equal to <code>count($tasks)</code></p>
<p>However, when I copy paste the exact same loop on top of it, now working with <code>$tasklists</code> the loop stops after just one iteration. Mind you that when I tested <code>count($tasklists)</code> does return for example 3 and in the loop when I echo <code>$i</code> it does echo 0 the first time.</p>
<p>Here is the code with a bunch of comments.</p>
<pre><code>// First let's break up all the tasklists the project has
$tasklists = explode('&', $data['proj_tasklists']);
// Now lets get all the tasks for each tasklist
for($i = 0; $i < count($tasklists); $i++) {
// Get list_tasks from the tasklist
$sql_get = "SELECT * FROM tasklists WHERE list_id='".$tasklists[$i]."'";
$result_get = mysqli_query($con, $sql_get);
if($result_get) {
// Now load in the variable
while($results = mysqli_fetch_array($result_get)) {
$data['list_tasks'] = $results['list_tasks'];
};
// Now let's break that up
$tasks = explode('&',$data['list_tasks']);
// Now reset list_tasks
$data['list_tasks'] = '';
// Do something for every task
for($i = 0; $i < count($tasks); $i++) {
// And get the info for the set task
$sql_get = "SELECT * FROM tasks WHERE task_id='".$tasks[$i]."'";
$result_get = mysqli_query($con, $sql_get);
if($result_get) {
// Now load it's task_user in a variable
while($results = mysqli_fetch_array($result_get)) {
$data['task_user'] = $results['task_user'];
};
// Check if that is the same as that of the user whom was deleted
if($data['task_user'] == $data['user_id']) {
// If the Id is the same update it to ''
$sql_update = "UPDATE tasks SET task_user='' WHERE task_id='".$tasks[$i]."'";
if (mysqli_query($con, $sql_update)) {
// If that worked then add this to the list of addjusted IDs
// First check if the variable is empty or not
if($data['adjusted'] == '') {
// Add the ID plainly
$data['adjusted'] = $tasks[$i];
} else {
// Otherwise preceed the ID with an &
$data['adjusted'] = $data['adjusted'].'&'.$tasks[$i];
};
} else {
// Return an error
echo json_encode(array(
'status'=>'unsuccesful',
'where'=>3
));
// Exit the php before it returns an succes state
exit();
};
};
// Now reset task_user
$data['task_user'] = '';
} else {
// Return an error
echo json_encode(array(
'status'=>'unsuccesful',
'where'=>2
));
// Exit the php before it returns an succes state
exit();
};
};
} else {
// Return an error
echo json_encode(array(
'status'=>'unsuccesful',
'where'=>1
));
// Exit the php before it returns an succes state
exit();

Getting data from a input textfield then use it in MySQL statement on the same page
|
<p>sorry for the bulk of code :)</p>
<p>I need to input a client name in the input textfield name clientname then i need to output the client information from my database when i click a button name loadcliinfo. But the problem is <strong> i don't know how will i get the data inputted in clientname? </strong> so I used <strong>$_POST['clientname']</strong>. The code is not working.</p>
<p>the code i pasted below is located on the same file.</p>
<pre><code> <tr>

</tr>
</code></pre>
<p><strong>my php code</strong> </p>
<pre><code> <?php
$name=isset($_POST['clientname'])? $_POST['clientname'] : '';
</code></pre>
<p>I get the data using this statement <strong>isset($_POST['clientname'])? $_POST['clientname'] : '' </strong> and store it in the variable $name but when i output the variable its empty. </p>
<pre><code> $csql="Select address, email, contactperson, contactno from client where name='$name'";
$result=$db->prepare($csql);
$result->execute();
while($resu= $result->fetch(PDO::FETCH_ASSOC))
{

echo '<input type="hidden" id="contactperson" value="'.$resu['contactperson'].'"/>';
echo '<input type="hidden" id="contactno" value="'.$resu['contactno'].'"/>';
}
?>
</code></pre>
<p><strong>My loadclientinfo function</strong></p>
<pre><code> <script>
function loadclientinfo()

var add=document.getElementById("add");
var email=document.getElementById("email");
var contactperson=document.getElementById("contactperson");

<p>I think <strong>getting data from clientname is the problem.</strong> Is there any way i could get the data from clientname on the same page?
thanks :D </p>

Cannot operate on year value of regular expression
|
<p>This is my first question here so please forgive and educate on any formatting errors. I am new to Python and going through automate the boring stuff. Decided to expand the date detection project by using the clipboard and formatting some things also. The problem I have is in any operation taken on the year part of the REGEX.
I have commented out my last attempt to validate the year and gave up and changed the REGEX to only find dates from 1000 to 2999 and skipped code validation of the dates.
I now need to validate leap years but I'm back to having to work with the year variable, but once again no operation has any effect.
Basically the problem is I can extract the year value and display it but I cannot modify it or do checks against it.</p>

Intermittent Stale Element Reference Exception
|
<p>I am writing a python selenium script to scrape data from a website. The script reads the employee identification number, name and date of birth from a CSV file and copies it to a Dictionary & then enters data from each line into a form and then clicks a submit button.
The next page that appears asks for the years of employment history which defaults to one year which is fine for my use case so the only thing the script does on this page is click the search button.
The script works consistently for approximately 20 to 35 employees. But at some point the script will fail with the following stale element reference exception:</p>
<blockquote>
<p>Message: The element reference of <strong></strong> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed</p>
</blockquote>
<p>The relevant HTML for the Search button is:</p>
<pre><code><div data-container="" class="btn-label OSInline">Search</div>
</button>
</div>
</div>
</div><div data-container="" style="text-align: center;" id="b8-ResetFilters2"><a data-link="" href="#" style="width: auto;"><span data-expression="" style="width: auto;">Reset Search</span></a>
</div>
</div>
</div>
<div
</code></pre>
<p>The relevant Python Selenium code is (GO DOWN TO "*****" TO SEE WHERE I THE SEARCH BUTTON IS):</p>
<pre><code># Open MOCemployees.csv as readable file & then convert to a Python Dictionary

Is there a way to only add verified email addresses to Firebase authentication console (React JS)?
|
<p>I'm trying to create a Firebase authentication system in my React web app. I know how to register an account and I know how to send a verification email out. Upon registration it sends the verification email which is fine, but the account gets added to the Firebase console database before the user has even verified it. I want it to be such that only verified accounts are added to the database.</p>
<p>Here is my code:</p>
<pre><code>import React, { useState, useEffect, useRef } from 'react'
import './join.css'
import { Link, useNavigate } from 'react-router-dom'
import { auth } from '../firebase'
import { createUserWithEmailAndPassword, onAuthStateChanged, sendEmailVerification } from "firebase/auth"
export default function Join() {
const [registerEmail, setRegisterEmail] = useState('');
const [registerPassword, setRegisterPassword] = useState('');
const [confirmPassword, setConfirmPassword] = useState('');
const [user, setUser] = useState({});
const verificationMessage = useRef();
useEffect(() => {
onAuthStateChanged(auth, (currentUser) => {
setUser(currentUser);
});
}, [])
const navigate = useNavigate();
const register = async () => {
try {
const user = await createUserWithEmailAndPassword(auth, registerEmail, registerPassword);
console.log(user);
} catch (error) {
console.log(error.message);
}
}
const handleSubmit = event => {
if (registerPassword === confirmPassword) {
sendEmailVerification(auth.currentUser);
verificationMessage.current.style.display = 'block';
register();
event.preventDefault();
}
else {
alert('Passwords do not match, please try again!');
event.preventDefault();
}
}
return (

inline expansion compiles into a function call [c++]
|
<h2>Introduction:</h2>
<p>I have been creating a simple wrapper classes. I randomly found out that <em>(or it appears to be)</em> an inline function still compiled into a function call. I created an example class to test things out and this is what I found:</p>
<p><strong>Consider the following class:</strong> </p>
<pre><code>//compile with MSVC
class InlineTestClass
{
public:
int InternalInt;
int GetInt() {return InternalInt;}
inline int GetInt_Inl() {return InternalInt;}
//__forceinline -Forces the compiler to implement the function as inline
__forceinline int GetInt_ForceInl() {return InternalInt;}
};
</code></pre>
<p><strong>This class has 3 functions for reference.</strong> </p>
<ul>
<li>The <strong>GetInt</strong> function is a standard function. </li>
<li>The <strong>GetInt_Inl</strong> function is an inline function.</li>
<li>The <strong>GetInt_ForceInl</strong> function is an ensured inline function in case of the
compiler deciding not to implement <strong>GetInt_Inl</strong> as inline function</li>
</ul>
<p>Implemented like so:</p>
<pre><code>InlineTestClass itc;
itc.InternalInt = 3;
int myInt;
myInt = itc.InternalInt; //No function
myInt = itc.GetInt(); //Normal function
myInt = itc.GetInt_Inl(); //Inline function
myInt = itc.GetInt_ForceInl(); //Forced inline function
</code></pre>
<p>The resulting assembler code of the setting of myInt (taken from dissassembler):</p>
<pre><code> 451 myInt = itc.InternalInt;
0x7ff6fe0d4cae <+0x003e> mov eax,dword ptr [rsp+20h]
0x7ff6fe0d4cb2 <+0x0042> mov dword ptr [rsp+38h],eax
452 myInt = itc.GetInt();
0x7ff6fe0d4cb6 <+0x0046> lea rcx,[rsp+20h]
0x7ff6fe0d4cbb <+0x004b> call nD_Render!ILT+2125(?GetIntInlineTestClassQEAAHXZ) (00007ff6`fe0d1852)
0x7ff6fe0d4cc0 <+0x0050> mov dword ptr [rsp+38h],eax
453 myInt = itc.GetInt_Inl();
0x7ff6fe0d4cc4 <+0x0054> lea rcx,[rsp+20h]
0x7ff6fe0d4cc9 <+0x0059> call nD_Render!ILT+1885(?GetInt_InlInlineTestClassQEAAHXZ) (00007ff6`fe0d1762)
0x7ff6fe0d4cce <+0x005e> mov dword ptr [rsp+38h],eax
454 myInt = itc.GetInt_ForceInl();
0x7ff6fe0d4cd2 <+0x0062> lea rcx,[rsp+20h]
0x7ff6fe0d4cd7 <+0x0067> call nD_Render!ILT+715(?GetInt_ForceInlInlineTestClassQEAAHXZ) (00007ff6`fe0d12d0)
0x7ff6fe0d4cdc <+0x006c> mov dword ptr [rsp+38h],eax
</code></pre>
<p>As shown above the setting (of myInt) from the <strong>member</strong> of InlineTestClass directly is <em>(as expected)</em> 2 mov instructions long.
Setting from the <strong>GetInt</strong> function results in a function call <em>(as expected)</em>, however both of the <strong>GetInt_Inl</strong> and <strong>GetInt_ForceInl</strong> (inline functions) also result in a function call. </p>
<p>It appears as if the inline function has been compiled as a normal function ignoring the inlining completely <em>(correct me if I am wrong)</em>.</p>
<p>This is strange cause according to <a href="https://msdn.microsoft.com/en-us/library/bw1hbe6y.aspx" rel="nofollow noreferrer">MSVC documentation</a>:</p>
<blockquote>
<p>The inline and __inline specifiers instruct the compiler to insert a
copy of the function body into each place the function is called.</p>
</blockquote>
<p>Which <em>(I think)</em> would result in:</p>
<pre><code>inline int GetInt_Inl() {return InternalInt; //Is the function body}
myInt = itc.GetInt_Inl(); //Call site
//Should result in
myInt = itc.InternalInt; //Identical to setting from the member directly
</code></pre>
<p>Which means that the assembler code should be also identical to the one of setting from the class member directly but it isn't.</p>
<h2>Questions:</h2>
<ol>
<li>Am I missing something or implementing the functions incorrectly?</li>
<li>Am I interpreting the function of the inline keyword? What is it?</li>
<li>Why do these inline functions result in a function call?</li>
</ol>

vue-tables-2 — $emit from custom filter not making it to callback?
|
<p>I'm struggling to get a custom filter in vue-tables-2 to emit an event from a nested, single-page component in Vue. The problem may be that I'm not capturing / handling it correctly upstream.</p>
<p>I have a custom filter <code><filter-brand /></code> inside a custom template for <code>dataTable</code> which emits <code>Event.$emit("vue-tables.filter::filterByBrand", this.brand)</code>.</p>
<p>I want to capture this 'filterByBrand' event in a top-level, router component called <code><Grid /></code> which is where I have my <code><v-client-table /></code> plus the attendant options including my <code>customFilters</code>.</p>
<p>Any thoughts on where I've gotten off course?</p>
<p><strong>Grid.vue</strong></p>
<pre><code>...
customFilters: [
{
name: "filterByBrand",
callback: function(row, query) {
console.log("filter=", query); // nothing?
return row.name[0] === query;
},
},
],
...
</code></pre>
<p><strong>main.js</strong></p>
<pre><code>import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import { ClientTable, Event } from "vue-tables-2";

PFQueryTablViewController queryForTable method with network reachability
|
<p>I am trying to populate a PFQueryTableViewController with Question objects from my Parse backend. How do I implement blocks within this method? </p>
<pre><code>- (PFQuery *)queryForTable // I'm having issues with using the method "findObjectInBackgroundWithBlock" in this method.
{
PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];
[query fromLocalDatastore];
[query orderByDescending:@"createdAt"];
[query findObjectsInBackgroundWithBlock:^(NSArray *parseQuestions, NSError *error) { // Fetch from local datastore
if (parseQuestions != nil) {
NSMutableArray *mutableParseQuestions = [parseQuestions mutableCopy];
self.questions = mutableParseQuestions; // if Set local array to fetched Parse questions
} else {
if ([InternetReachabilityManager isReachable]) {
[query findObjectsInBackgroundWithBlock:^(NSArray *parseQuestions, NSError *error) { // Fetch from Cloud
NSMutableArray *mutableParseQuestions = [parseQuestions mutableCopy];
self.questions = mutableParseQuestions; // if Set local array to fetched Parse questions
[Question pinAllInBackground:parseQuestions]; // Save query results to local datastore
}];
}
}
}];
return query;
}
</code></pre>
<p>When blocks are in this method I get this error.
<a href="https://i.stack.imgur.com/9SJnC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/9SJnC.png" alt="enter image description here"></a></p>
<p>Is this because queryForTable is already a background process? Should I just use </p>
<blockquote>
<p>[query findObjects]</p>
</blockquote>
<p>Also, I'm trying to implement reachability into my fetch. </p>
<ol>
<li>Try fetching from local datastore </li>
<li>Load data into table if they are there else switch to the network </li>
<li>Call block if network is available</li>
<li>Save the results of the network fetch into the local datastore</li>
</ol>
<p>I know that this method is supposed to automatically assign objects it fetches to rows but I don't know how to work with it if we're passing around a PFObject subclass object. This is my explanation for the arrays.</p>
<pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
self.question = [self.questions objectAtIndex:indexPath.row]; // Save one question from row
static NSString *identifier = @"QuestionsCell";
QuestionsCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[QuestionsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
}
[cell setQuestion:self.question]; //
return cell;
}
</code></pre>
<p>This is how I use the fetched array to populate the tableView.</p>
<p>So my questions:</p>
<ol>
<li>Why can't I call a block inside of queryForTable?</li>
<li>Is there any way I can make this simpler by using queryForTable's automatic assigning of objects to rows?</li>
<li>If the internet is unreachable and the local datastore is empty what should I do?</li>
</ol>

HtmlUnit infinite loop when redirect link after the form submit is same as the one containing form
|
<p>I am trying to login to a web page <a href="https://online.firstdata.de/esp/concardis/" rel="nofollow noreferrer">https://online.firstdata.de/esp/concardis/</a> using HTMLunit library in Java. The thing is that this page contains a form inside a couple of iframes. The source of the iframe containing the form is <a href="https://online.firstdata.de/login/postlogin/UserDispatcher" rel="nofollow noreferrer">https://online.firstdata.de/login/postlogin/UserDispatcher</a>
. When a form is submitted then one of the redirect links before the next page is rendered is also the same link as mentioned above.
So, this creates an infinite loop when I use it from Java. However, when the login happens from the browser because the main source of the originating page was the link ending with /concardis the redirect link is not the same as this link and hence there is no infinite loop. How can I simulate this same behaviour from Java? Here is my code :</p>
<pre><code>WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getOptions().setRedirectEnabled(true);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setCssEnabled(false);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
try{
HtmlPage page1 = null;
HtmlPage page2 = null;
HtmlPage page3 = null;
HtmlPage page = webClient.getPage("https://online.firstdata.de/esp/concardis");
List<FrameWindow> frames = page.getFrames();
for (FrameWindow frame : frames) {
if (frame.getFrameElement().getNameAttribute().equals("application")) {
page1 = webClient.getPage(frame.getEnclosedPage().getUrl());
}
}
List<FrameWindow> frames1 = page1.getFrames();
for (FrameWindow frame : frames1) {
if (frame.getFrameElement().getNameAttribute().equals("content")) {
page2 = webClient.getPage(frame.getEnclosedPage().getUrl());
}
}
List<FrameWindow> frames2 = page2.getFrames();
for (FrameWindow frame : frames2) {
if (frame.getFrameElement().getId().equals("loginFrame")) {
page3 = webClient.getPage(frame.getFrameElement().getSrcAttribute());
}
}
HtmlForm form = page3.getFormByName("loginForm");
HtmlTextInput userName = form.getInputByName("j_username");
HtmlPasswordInput password = form.getInputByName("j_password");
userName.setValueAttribute("username");
password.setValueAttribute("password");
HtmlSubmitInput submit = form.getInputByName("Submit");
submit.click();

hashchange event possible bug
|
<p>I think I've found a really unusual bug in Javascript but I'm not sure.</p>
<p>So I have three child divs absolutely positioned inside a parent div (that is position relative).</p>
<p>The three child divs are 1200px wide and are <strong>side by side</strong> inside the parent.</p>
<p>So the first div is left:0px the second is left:1200px and the third is left:2400px.</p>
<p>Now my goal is to click and the divs shift. (The parent div is acting as a 1200px viewport)</p>
<pre><code>$("#blogNav").click(function()
{
$("#blog").css( "left", "0px");
$("#software").css( "left", "1200px");
$("#about").css( "left", "2400px");
});
$("#softwareNav").click(function()
{
$("#blog").css( "left", "-1200px");
$("#software").css( "left", "0px");
$("#about").css( "left", "1200px");
});
$("#aboutNav").click(function()
{
$("#blog").css( "left", "-2400px");
$("#software").css( "left", "-1200px");
$("#about").css( "left", "0px");
});
</code></pre>
<p>THIS WORKS PERFECTLY.</p>
<p>Now here's the issue.</p>
<p>When I do the exact same thing with a hashchange event:</p>
<pre><code>window.onhashchange = function()
{
if(window.location.hash=="#blog")
{
$("#blog").css( "left", "0px");
$("#software").css( "left", "1200px");
$("#about").css( "left", "2400px");
}
if(window.location.hash=="#software")
{
$("#blog").css( "left", "-1200px");
$("#software").css( "left", "0px");
$("#about").css( "left", "1200px");
}
if(window.location.hash=="#about")
{
$("#blog").css( "left", "-2400px");
$("#software").css( "left", "-1200px");
$("#about").css( "left", "0px");
}
};
</code></pre>
<p>THE POSITIONING IS ALL MESSED UP.</p>
<p>The 0px location of the parent div is shifted so that the 0px is no longer the left border of the parent div. Its at some negative margin.</p>
<p>The only thing that has change is the hashevent.</p>
<p>I hope I'm explaining this well enough.</p>
<p>I'll try to upload some examples to my site soon.</p>
<p>It's really strange how the exact same logic works with a click event but not with a hashchange event.</p>

Audio playback using ffmpeg and audiotrack android

<p>I am trying to play mp3 audio in android using ffmpeg and audiotrack. But i'm getting only garbled audio output. Can anyone suggest where could be the problem ?. Here entire player runs in JNI code.
All other ffmpeg and audio track initializations are also done before starting this thread.</p>

php artisan error after repo clone SQLSTATE[42S02]: Base table or view not found:

<p>I made a Laravel project with Jetstream and uploaded it to Github. After my colleague and I tried to execute <code>composer install</code>, we received the following error:</p>

<p>We tried again without the scripts in <code>composer.json</code>, went well, but after each and every artisan-command we try, we get the following exception:</p>

<p>This also happens when we try to execute <code>php artisan migrate</code>, the command which should solve this error.</p>
<p>So, what can we try now?</p>

Cleaning a SQL schema before using SQL Developer Database copy tool
|
<p>I have a database for an application and several environment (development, test and production). I would like to use the option <strong>Database copy</strong> from <strong>SQL Developer</strong> in order to retrieve data from the production and copy them in development. Thus data on both environments will be the same.</p>
<p>With a previous version of the program all was working perfectly. Nevertheless with a new version (SQL Developer 18.2) imposed by our company, I obtain several error with different objects like sequences, existing table, primary key, ...) during the copy.</p>
<p>Thus I would like to use a script for cleaning the objects of the Database before to use the tool in order to see if the problem will be solved. But I don't know how to do that.</p>
<p>I found and updated this script:</p>
<pre><code>BEGIN
FOR cur_rec IN (SELECT object_name, object_type
FROM user_objects
WHERE object_type IN
('TABLE',
'VIEW',
'PACKAGE',
'PROCEDURE',
'FUNCTION',
'SEQUENCE',
'SYNONYM'
))
LOOP
BEGIN
IF cur_rec.object_type = 'TABLE'
THEN
EXECUTE IMMEDIATE 'DROP '
|| cur_rec.object_type
|| ' "'
|| cur_rec.object_name
|| '" CASCADE CONSTRAINTS';
ELSE
EXECUTE IMMEDIATE 'DROP '
|| cur_rec.object_type
|| ' "'
|| cur_rec.object_name
|| '"';
END IF;
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line ( 'FAILED: DROP '
|| cur_rec.object_type
|| ' "'
|| cur_rec.object_name
|| '"'
);
END;
END LOOP;
END;
</code></pre>
<p>Nevertheless this script Cleanup the Schema by DROPPING all objects. I would like to keep the structure and the objects but just empty the conten.</p>
<p>Could you please help me how to do for cleaning the different object without deleting them and importing again?</p>
<p>Thank in advance for your help.</p>
<p>Sebastien</p>

Python - Help me find a better way to extract and join all hashtags into a new dict value for each tweet
|
<p>I am attempting to parse some Twitter data that is from the Twitter Streaming API and is stored in a nested JSON format. I would like to create a new dict key:value pair called <code>'HASHTAGS'</code> that holds all of the hashtags in an array. I do not want to use a regex to extract the values from the tweet text, instead, I want to do this based on the nested JSON metadata field <code>['entities']['hashtags']['text']</code>.</p>
<p>The difficulty comes into the fact that not all tweets have a hashtag, and therefore might not have this field. On top of this, some tweets might have multiple hashtags, and I want to extract all of them, not just the first one. </p>
<p>I think I've found a way to do this, but it seems very clunky, and not ideal. Also, this only creates the dict <code>'HASHTAGS'</code> for tweets that have a hashtag. I want <code>'HASHTAGS'</code> to be created for every record, but only be populated for records that have a hashtag, including multiple hashtags. </p>

<p>I am dealing with experimental measurements of time-correlated gamma-ray emissions with a pair of detectors. I have a long-form dataframe which lists every gamma-ray detected and displays its energy, the timestamp of the event, and the detector channel. Here is the sample structure of this dataframe:</p>
<pre><code>df
Energy Timestamp Channel
0 639 753437128196030 1
1 798 753437128196010 2
2 314 753437131148580 1
3 593 753437131148510 2
4 2341 753437133607800 1
</code></pre>
<p>I must filter these data and according to the following conditions:
Return the energies of all events detected in Channel 1 which occur within one user-selectable <code>timing_window</code> of events detected in Channel 2.
Furthermore, only the events in Channel 2 that are within the energy range <code>[E_lo, E_hi]</code> should be considered when evaluating the timing window conditions.</p>
<p>So far, I have tried the following:</p>
<p>Separate the energy data of each detector into individual dataframes:</p>
<pre><code>d1_all = df[(df["Channel"] == 1)]
d2_all = df[(df["Channel"] == 2)]
</code></pre>
<p>Reset the indices of <code>d1_all</code>:</p>
<pre><code>d1_all = d1_all.reset_index()
d1_all = d1_all.drop(['index'], axis=1)
d1_all.head()
</code></pre>
<p>Retain only the events in <code>d2_all</code> which occur in the range <code>[E_lo=300, E_hi=600]</code></p>
<pre><code>d2_gate = d2_all[(d2_all["Energy"] >= 300) & (d2_all["Energy"] <=600)]
</code></pre>
<p>Reset the indices of <code>d2_all</code>:</p>
<pre><code>d2_gate = d2_gate.reset_index()
d2_gate = d2_gate.drop(['index'], axis=1)
d2_gate.head()
</code></pre>
<p><em>Everything up to this point works fine.</em> <strong>Here is the biggest problem.</strong> The following code evaluates each event in detector 1 to determine if its timestamp is within one <code>timing_window</code> of the timestamp corresponding to ANY event within the energy range E_lo to E_hi in detector 2. The problem is that this dataframe can have on the order of 10's to 100's of thousands of entries for each detector, and the current code takes essentially forever to run. This code uses nested <code>for</code> loops.</p>
<pre><code>for i in range(0, d1_all.shape[0]):
coincidence = False
for j in range(0, d2_gate.shape[0]):
if ((d1_all.iloc[i]["Timestamp"]) >=
(d2_gate.iloc[j]["Timestamp"] - coin_window)) and ((d1_all.iloc[i]
["Timestamp"]) <= (d2_gate.iloc[j]["Timestamp"] + coin_window)):
coincidence = True
break
else:
pass
if coincidence == True:
pass
elif coincidence == False:
d1_all = d1_all.drop([i])
</code></pre>
<p>Any help identifying a faster implementation of evaluating for coincidences would be greatly appreciated! Thank you!</p>

The tmx map is only rendering two blocks into the screen and all the rest is black

<p><a href="https://i.stack.imgur.com/EI5rX.png" rel="nofollow noreferrer">The print from my game</a></p>
<p>I'm learning to develope a game like supermario through a tutorial on youtube (<a href="https://www.youtube.com/watch?v=P8jgD-V5jG8&t=43s" rel="nofollow noreferrer">https://www.youtube.com/watch?v=P8jgD-V5jG8&t=43s</a>), the code that the author of the tutorial makes available in his github is <strong>still working today</strong>, however it is the complete code of the game, and I am still in video class 6, because it was here that his result got different from mine (as you can see from the image).</p>
<p>I would be very grateful if any of you more experienced developers could tell me where I'm wrong to be only showing up 2 blocks of tmx map. I apologize for my english, thanks for trying to help.</p>

INVALID_CLIENT: Invalid redirect URI error when running GitHub pages application. Uses Spotify API
|
<p>I've deployed a React application to GitHub pages that uses the Spotify API to get the currently playing track on Spotify and display it in the web page. This runs great locally and used a local server running on port 8888 to send the api requests and redirect to the app running on localhost:3000. The issue is that the app as is gives the above error when I attempt to request the token from the Spotify API and I'm guessing it's because the redirect uri that I'm using is no longer valid since the app is now on GitHub and can't communicate with localhost:3000.</p>
<p>The following is the code that ran on localhost:8888 and retrieved the access token. I changed my redirect URI to match the location of the hosted version of the app.</p>

Handling processes in C
|
<p>I have a problem when trying to handle a SIGUSR1 signal sent from a father process to all of his child's process. The handler on the child's does nothing. I checked for the result of the kill command and it returns 0 meaning that the message sent was ok . Can anyone help with this? Below is the code of the child process. I use execl to differ the childs code from the father. Note that the handler works well for alarm calls</p>
<pre><code>#include <stdio.h>

int fd[2];
/*Handler for the alarm and SIGUSR1 signal*/
void signal_handler (int sig)
{
printf("******************");

{
printf("Im child with pid:%d im going to die my value is %lf \n",getpid(),result);
alarmflag=1;
}

result=3;
double prosimo=-1;
while(!alarmflag)

AngularJS Modal Service Stops Working
|
<p>I've created a <code>modal</code> service within my Angular app that I can inject into controllers or directives. I'm running into a problem where after opening/closing a modal multiple times, everything within the modal stops workings. The modal works by grabbing content from a hidden div on the page and popping it into the modal. I've been able to determine that at some point, the value of <code>modal.settings</code> changes. If I insert a <code>debugger</code> at the beginning of my <code>modal.open</code> function and save the value of <code>var x = settings</code> in my console, I can see that after a few cycles, <code>x !== settings</code>. I've also tried comparing <code>modal.settings</code>, but the same thing happens. Eventually, after a few cycles, <code>modal.settings</code> changes and things stop working.</p>
<p>I think I need to refactor this service, but I'm not sure where to start and could use some guidance.</p>
<p>Here is the service code:</p>
<pre><code>app.service('modal', ['$compile', function($compile) {
var modal = this;
modal.settings;
modal.contents;
modal.overlay = $('<div id="overlay"></div>');
modal.modal = $('<div id="modal"></div>');
modal.content = $('<div id="content"></div>');
modal.closeBtn = $('<div id="close"><i class="fa fa-times"></div>');
modal.modal.hide();
modal.overlay.hide();
modal.modal.append(modal.content, modal.closeBtn);
$(document).ready(function(){
$('body').append(modal.overlay, modal.modal);
});
modal.open = function (settings) {
if(!modal.settings) {
modal.settings = settings;
}
modal.content.empty().append(modal.settings.content);
if(modal.settings.class) modal.modal.addClass(modal.settings.class);
if(modal.settings.height) modal.modal.css({ height: modal.settings.height });
if(modal.settings.width) modal.modal.css({ width: modal.settings.width });
if(modal.settings.content_height) modal.modal.css({ height: modal.settings.content_height });
if(modal.settings.content_width) modal.modal.css({ width: modal.settings.content_width });
if(modal.settings.fitToWindow) {
modal.settings.width = $(window).width() - 160;
modal.settings.height = $(window).height() - 160;
};
center(modal.settings.top);
$(window).bind('resize.modal', center);
modal.modal.show();
modal.overlay.show();
$(modal.closeBtn).add(modal.overlay).on('click', function(e) {
e.stopPropagation();
modal.close();
});
$(document).on('keyup', function(e) {
if (e.keyCode == 27) {
modal.close();
$(document).unbind('keyup');
}
})
};
modal.close = function() {
debugger;
modal.settings.elem.empty().append(modal.settings.content);
modal.modal.hide();
modal.overlay.hide();
modal.content.empty();
$(window).unbind('resize.modal');
};
function center(top) {
if(!top || !isInt(top)) top = 130;
var mLeft = -1 * modal.modal.width() / 2;
modal.modal.css({
top: top + 'px',
left: '50%',
marginLeft: mLeft
});
function isInt(n) {
return n % 1 === 0;
}
}
}]);
</code></pre>
<p>Here is how the modal is opened from the controller or directive:</p>
<pre><code>modal.open({
content: $('#edit_story_' + story.id),
elem: $('#edit_story_' + story.id + '_container')
});
</code></pre>
<p>I also tried running my <code>elem</code> through the compiler first like so:</p>
<pre><code>modal.open({
content: $compile($('#edit_story_' + story.id))($scope),
elem: $('#edit_story_' + story.id + '_container')
});
</code></pre>
<p>That solved my initial problem, but now after a few cycles my modal contents are duplicated. I get one form stacked upon another.</p>

Global variables between C and C++
|
<p>I'm developing a mixed C/C++ program for an ARM STM32F4, but I have problems in accessing global variables defined in the C part.
Here is a simple test code to reproduce the problem.</p>
<p>test.h:</p>
<pre><code>#ifndef TEST_H_
#define TEST_H_
#ifdef __cplusplus
extern "C" {
#endif
extern const char* strings[];
#ifdef __cplusplus
}
#endif
#endif /* TEST_H_ */
</code></pre>
<p>test.c:</p>
<pre><code>#include <test.h>
const char* strings[] = {"string a", "string b", "string c" };
</code></pre>
<p>main.hpp</p>
<pre><code>#ifndef MAIN_HPP_
#define MAIN_HPP_
#define STM32F4
#include <test.h>
#include <libopencm3/stm32/rcc.h>
#include <libopencm3/stm32/gpio.h>
#endif /* MAIN_HPP_ */
</code></pre>
<p>main.cpp:</p>
<pre><code>#include <main.hpp>
int main(void)
{
char s2[3][9];
rcc_periph_clock_enable(RCC_GPIOD);
gpio_mode_setup(GPIOD, GPIO_MODE_OUTPUT, GPIO_PUPD_NONE,
GPIO12);
while (1) {
for (int i = 0; i < 3; i++) {
for (int j = 0; j < 9; j++) {
s2[i][j] = strings[i][j];
if (s2[i][j] == 'i') {
gpio_toggle(GPIOD, GPIO12);
}
for (int k = 0; k < 1000000; k++) {
__asm__("nop");
}
}
}
}
}
</code></pre>
<p>However, when I run it in the debugger I can see that the memory where strings[0] (for example) is pointing is completely zeroed.</p>
<p>Note: the part in the while loop is not relevant, I've just added it to have some feedback and to avoid that the compiler strips the unused values of strings.</p>
<p>So what am I doing wrong here?</p>
<p><strong>EDIT</strong></p>
<p>I'm working with Eclipse under Linux, gnu-arm-none-eabi.</p>

</code></pre>
<p><strong>EDIT</strong></p>
<p>I'm looking into the problem but I'm a bit puzzled.</p>
<p>The startup code includes the following:</p>
<pre><code>for (src = &_data_loadaddr, dest = &_data;
dest < &_edata;
src++, dest++) {
*dest = *src;
}
</code></pre>
<p>So it seems ok to me.</p>
<p>The .map file gives the following infos:</p>
<pre><code>.data 0x0000000020000000 0xc load address 0x000000000800038c
0x0000000020000000 _data = .
*(.data*)
.data.strings 0x0000000020000000 0xc ./src/test.o
0x0000000020000000 strings
0x000000002000000c . = ALIGN (0x4)
0x000000002000000c _edata = .
0x000000002000000c _data = .
*(.data*)
0x000000002000000c . = ALIGN (0x4)
0x000000002000000c _edata = .
0x000000000800038c _data_loadaddr = LOADADDR (.data)
.igot.plt 0x000000002000000c 0x0 load address 0x0000000008000398
</code></pre>
<p>Now, when I run the debugger I see that right from the start &_data==&_edata==0x2000000c , and I notice also that _data is present two times in the .map file.</p>
<p>So, is there an error in the linker script?</p>

Get the average of the values of one column for the values in another
|
<p>I was not so sure how to ask this question. i am trying to answer what is the average tone when an initiative is mentioned and additionally when a topic, and a goal( or achievement) are mentioned. My dataframe (df) has many mentions of 70 initiatives (rows). meaning my df has 500+ rows of data, but only 70 Initiatives.</p>
<p>My data looks like this</p>
<pre><code>> tabmean
Initiative Topic Goals Achievements Tone
1 52 44 2 2 2
2 294 42 2 2 2
3 103 31 2 2 2
4 52 41 2 2 2
5 87 26 2 1 1
6 52 87 2 2 2
7 136 81 2 2 2
8 19 7 2 2 1
9 19 4 2 2 2
10 0 63 2 2 2
11 0 25 2 2 2
12 19 51 2 2 2
13 52 51 2 2 2
14 108 94 2 2 1
15 52 89 2 2 2
16 110 37 2 2 2
17 247 25 2 2 2
18 66 95 2 2 2
19 24 49 2 2 2
20 24 110 2 2 2
</code></pre>
<p>I want to find what is the mean or average Tone when an Initiative is mentioned. as well as what is the Tone when an Initiative, a Topic and a Goal are mentioned at the same time. The code options for Tone are : positive(coded: 1), neutral(2), negative (coded:3), and both positive and negative(4). Goals and Achievements are coded yes(1) and no(2).</p>
<p>I have used this code:</p>
<pre><code>GoalMeanTone <- tabmean %>%
group_by(Initiative,Topic,Goals,Tone) %>%
summarize(averagetone = mean(Tone))
</code></pre>
<p>With Solution output :</p>
<pre><code>GoalMeanTone
# A tibble: 454 x 5
# Groups: Initiative, Topic, Goals [424]
Initiative Topic Goals Tone averagetone
<chr> <chr> <chr> <chr> <dbl>
1 0 104 2 0 NA
2 0 105 2 0 NA
3 0 22 2 0 NA
4 0 25 2 0 NA
5 0 29 2 0 NA
6 0 30 2 1 NA
7 0 31 1 1 NA
8 0 42 1 0 NA
9 0 44 2 0 NA
10 0 44 NA 0 NA
# ... with 444 more rows
</code></pre>
<p>note that for Initiative Value 0 means "other initiative".</p>
<p>and I've also tried this code</p>
<pre><code>library(plyr)
GoalMeanTone2 <- ddply( tabmean, .(Initiative), function(x) mean(tabmean$Tone) )
</code></pre>
<p>with solution output</p>
<pre><code>> GoalMeanTone2
Initiative V1
1 0 NA
2 1 NA
3 101 NA
4 102 NA
5 103 NA
6 104 NA
7 105 NA
8 107 NA
9 108 NA
10 110 NA
</code></pre>
<p>Note that in both instances, I do not get an average for Tone but instead get NA's</p>
<p>I have removed the NAs in the df from the column "Tone" also have tried to remove all the other mission values in the df ( its only about 30 values that i deleted).
and I have also re-coded the values for Tone :</p>
<pre><code>tabmean<-Meantable %>% mutate(Tone=recode(Tone,
`1`="1",
`2`="0",
`3`="-1",
`4`="2"))
</code></pre>
<p>I still cannot manage to get the average tone for an initiative. Maybe the solution is more obvious than i think, but have gotten stuck and have no idea how to proceed or solve this.</p>
<p>i'd be super grateful for a better code to get this. Thanks!</p>

Virtual keyboard in TASM
|
<p>I know it's quite a long-shot but I'm stuck in the middle of a school assembly project and as I'm pretty new to programming, I'm having a hard time tracking down the problem(s) in my code.</p>
<p>I'm trying to make an virtual (on-screen) keyboard. The values of the location of each button is found in 2 arrays, one for the X value of the center of the button, other for the Y.</p>
<p>Example arrays keyboard's top row:</p>
<pre><code>x_arr dw 13,37,61,85,109,133,157,181,205,229
y_arr dw 113,113,113,113,113,113,113,113,113,113
</code></pre>
<p>The computer waits for a mouse click from the user and using an algorithm finds if or which button was pressed, then matches that button with an array of ascii values of each letter:</p>
<pre><code>letter_arr db 81,87,68,82,84,89,85,73,79,80 ;QWERTYUIOP
</code></pre>
<p>My program doesn't seem to work. I'll add the full code and a picture of the keyboard itself.</p>
<p>Sorry if anything was bit messy. Thanks in advance!</p>

how to solve overlay2 make du report wrong disk size and make shell give no space left on disk error

<p>I use the same docker image to launch many containers, now, the /var/lib/docker/overlay2 take up all my disk space, when I login into the shell, it tells me that no space left on the disk, and features like tab completion is disabled.</p>
<p>But, ncdu show that I have a lot of space on disk.</p>
<p>So, what should I do to make the system report the right disk usage?</p>

Laravel query returns unexpected order
|
<p>I'm using Laravel Query Builder to get a set of rows, ordering them by 2 columns, <code>ticket_id</code> then <code>id</code> (previously <code>created_at</code>). However the result orders them by <code>ticket_id</code> (correct), but the <code>id</code> (or <code>created_at</code>) secondary order is incorrect. Am I approaching this wrong, misunderstanding ordering?</p>
<p>Here's my query:</p>
<pre><code>$responses = Response::where('status', '=', 'closed');
->select('id', 'ticket_id', 'created_at', 'author_id')
->orderBy('ticket_id', 'id')
->get();
</code></pre>
<p>Which in turn, returns:</p>
<pre><code> 0 => array:3 [
"ticket_id" => 14
"id" => 71
"time" => "2018-05-25 08:55:03"
]
1 => array:3 [
"ticket_id" => 14
"id" => 75
"time" => "2018-05-25 12:48:45"
]
2 => array:3 [
"ticket_id" => 14
"id" => 72
"time" => "2018-05-25 08:55:53"
]
3 => array:3 [
"ticket_id" => 13
"id" => 70
"time" => "2018-05-25 08:53:50"
]
4 => array:3 [
"ticket_id" => 13
"id" => 76
"time" => "2018-05-29 12:30:46"
]
5 => array:3 [
"ticket_id" => 13
"id" => 74
"time" => "2018-05-25 11:30:36"
]
</code></pre>
<p>You see for ticket 14, the order is 71, 75, 72, rather than 71, 72, 75.</p>
<p>Here's the table structure too:</p>
<pre><code>+------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+------------------+------+-----+---------+----------------+
| id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| ticket_id | int(11) | NO | | NULL | |
| author_id | int(11) | NO | | NULL | |
| status | int(11) | NO | | 0 | |
| content | text | NO | | NULL | |
| created_at | timestamp | YES | | NULL | |
| updated_at | timestamp | YES | | NULL | |
| assets | text | YES | | NULL | |
+------------+------------------+------+-----+---------+----------------+

Making a sidebar collapsable on mobile
|
<p>I have a row of two columns. The left column has a sidebar that stacks on top of the column on the right column on and below the iPad's width. I want it to be collapsible, show active link on as the title and dropdown to show the menu when clicked.</p>
<p>I have tried a few ways to achieve this but I cannot get it to work.</p>
<p>Here's the HTML:</p>
<pre><code><div class="col-lg-3 customer-portal-base">
<ul class="side-bar">
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">Account</a>
</li>
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">Orders</a>
</li>
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">Order details</a>
</li>
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">My details</a>
</li>
<li class="side-bar__item side-bar__item--is-active">
<a href="#" class="side-bar__item-link side-bar__item-link--is-active">Account settings</a>
</li>
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">Contact</a>
</li>
<li class="side-bar__item">
<a href="#" class="side-bar__item-link">Logout</a>
</li>
</ul>
</div>
</code></pre>
<p>And here's the SCSS:</p>
<pre><code>.side-bar {
padding: 0;
background-color: white;
list-style: none;
margin-top: 0;
width: 97%;
&__item {
&-link {
font-weight: lighter;
transition: all 0.5s;
&--is-active {
color: blue;
font-weight: 600;
&::after {
background-image: url("");
content: "";
display: inline-block;
background-repeat: no-repeat;
background-position: center center;
width: 1.8rem;
height: 1rem;
margin-left: 3rem;
transform: translateY(0.2rem);
@include sidebar-breakpoint {
display: none;
}
}
}

color: blue;
}
}

Triggers and Actions for Creature AI
|
<p>Despite my creature AI working (for the most part), I feel like the way I've set it up is terribly inefficient and likely committing some programming sins. I want to rewrite it to be more clean, efficient, and easier to maintain but I'm not exactly sure where to begin. </p>
<p>In my creature AI, I have a list of triggers, such as OnSpawn, OnDeath, or OnCollisionEnter. Within each trigger is a list of actions such as "Cast a Spell" or "Play an Animation". When a trigger's conditions are met, its list of actions are processed to check if it's not already in our processing list, adds it, and then plays their associated actions. When the trigger's conditions are not met, the list of actions are removed from this process list, and similarly processes through some remove functions to clean up behavior.</p>
<p>Some code that I've simplified:</p>
<pre><code> void Update()
{
if (canAct && !dead)
{
CheckTriggers();
PlayAllActions();
}
}
private void CheckTriggers()
{
for (int i = 0; i < actions.Length; i++)
{
switch (actions[i].trigger)
{
case ActionTrigger.Trigger.OnCollisionEnter:
if (isColliding)
AddActionList(actions[i].actionSetList);
else
RemoveActionList(actions[i].actionSetList);
break;
case ActionTrigger.Trigger.UponBeingAttacked:
if (hasBeenAttacked)
AddActionList(actions[i].actionSetList);
break;
}
}
}
public void AddActionList(ActionSetList actionSetList)
{
bool containsItem = existingActionsList.Any(item => item == actionSetList);
if (containsItem)
return;
existingActionsList.Add(actionSetList);
}
private void PlayAllActions()
{
if (existingActionsList.Count > 0)
for (int i = 0; i < existingActionsList.Count; i++)
ActionPlayEffect(existingActionsList[i]);
}
public void ActionPlayEffect(ActionSetList actionSetList)
{
for (int i = 0; i < actionSetList.Length; i++)
{
switch (actionSetList[i].type)
{
case ActionSet.Type.CastSpell:
if (spellRoutine == null && actionSetList[i].cooldownTimeRemaining <= 0)
spellRoutine = StartCoroutine(Cast(actionSetList[i]));
break;
case ActionSet.Type.PlayAnim:
if (!isInActionPose)
{
animator.SetTrigger("ActionTrigger");
animator.SetInteger("Action", (int)actionSetList[i].animToPlay+1);
isInActionPose = true;
}
break;
}
}
}
public void RemoveActionList(ActionSetList actionSetList)
{
bool containsItem = existingActionsList.Any(item => item == actionSetList);
if (containsItem)
{
ActionRemoveEffect(actionSetList);
existingActionsList.Remove(actionSetList);
}
}
public void ActionRemoveEffect(ActionSetList actionSetList)
{
for (int i = 0; i < actionSetList.Length; i++)
{
switch (actionSetList[i].type)
{
case ActionSet.Type.CastSpell:
CancelCast();
break;
case ActionSet.Type.PlayAnim:
animator.SetTrigger("ActionTrigger");
animator.SetInteger("Action", 0);
isInActionPose = false;
break;
}
}
}

<p>What can I do to build a more efficient creature AI?</p>

jQuery get() php button submit

<p>I have the following jquery code</p>
<pre><code>$(document).ready(function() {

}, 9000);
$("#responsecontainer2").load("testing.php?console=1");
var refreshId = setInterval(function() {
$("#responsecontainer2").load('testing.php?console=1');
}, 9000);
$('#chat_btn').click(function(event) {
event.preventDefault();
var say = jQuery('input[name="say"]').val()
if (say) {
jQuery.get('testing.php?action=chatsay', { say_input: say} );

});
});
</code></pre>
<p>Sample Form</p>
<pre><code> <form id=\"kick_player\" action=\"\">
<input type=\"hidden\" name=\"player\" value=\"$pdata[name]\">
<input type=\"submit\" id=\"kick_btn\" value=\"Kick Player\"></form>
</code></pre>
<p>And the handler code</p>
<pre><code>if ($_GET['action'] == 'chatsay') {
$name = USERNAME;
$chatsay = array($_GET['say_input'],$name);
$api->call("broadcastWithName",$chatsay);
die("type: ".$_GET['type']." ".$_GET['say_input']);
}
if ($_GET['action'] == 'consolesay') {
$consolesay = "§4[§f*§4]Broadcast: §f".$_GET['sayc_input'];
$say = array($consolesay);

$kickarray = array($kick);
$api->call("runConsoleCommand", $kickarray);
die("type: ".$_GET['type']." ".$_GET['player_input']);
}
</code></pre>
<p>When I click the button, it reloads the page for starters, and isn't supposed to, it also isn't processing my handler code. I've been messing with this for what seems like hours and I'm sure it's something stupid.</p>
<p>What I'm trying to do is have a single button (0 visible form fields) fire an event. If I have to have these on a seperate file, I can, but for simplicity I have it all on the same file. The die command to stop rest of file from loading. What could I possibly overlooking? </p>
<p>I added more code.. the chat_btn and console_btn code all work, which kick is setup identically (using a hidden field rather than a text field). I cant place whats wrong on why its not working :(</p>

My recyclerview data keeps getting doubled when i switch to some other fragment and return to that fragment which has the recyclerview
|
<p>I have a MainActivity where I replace the fragments in a FrameLayout using getSupportFragmentManager().beginTransaction.replace() and the PositionsFragment as given below. </p>
<p>When I open PositionFragment initially, data is perfectly displayed, but when I switch to dashboard and then again switch to PositionsFragment, the cards in the recyclerview get doubled. </p>
<p>They get doubled every time I switch. I tried clearing the arrayList using productList.clear(); but didn't work. </p>
<p>MainActivity where I replace the fragments.</p>
<pre><code>case R.id.nav_dashboard: getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new DashboardFragment()).commit();
toolbar.setTitle("Dashboard");
break;
case R.id.nav_positions:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new PositionsFragment()).commit();
toolbar.setTitle("Positions");
break;
</code></pre>
<p>PositionsFragment </p>
<pre><code>public class PositionsFragment extends Fragment{
public static Spinner spinner;
RecyclerView recyclerView;
ProgressBar progressBar;
ArrayList<Products> productList=new ArrayList<>();
ArrayList<String> positionsArray;
FloatingActionButton fab;

Validations pass but when merge() is called a validation error is thrown
|
<p>Sorry for asking here but I can't for the life of me understand what is going on. Been looking for answers all around the web for hours with no luck.</p>
<p>I have a simple Quiz modelled in JPA, using <a href="http://www.vraptor.org/" rel="nofollow">VRaptor</a> (an MVC framework) running in a WildFly 10.0.0.Final server which uses Hibernate 5.0.7.Final. A Quiz have many Questions which have <strong>2-10</strong> Alternatives each.</p>
<p>I'm currently implementing a method for users to add/remove Questions on a Quiz. Before calling <code>merge(quiz)</code> I run the validations to make sure everything is valid. It passes. I get no errors.</p>
<p>Since there are no validation errors, I call <code>merge(quiz)</code> and finally I'm greeted with the following exception:</p>
<pre><code>javax.validation.ConstraintViolationException: Validation failed for classes [game.Question] during persist time for groups [javax.validation.groups.Default, ]
List of constraint violations:[
ConstraintViolationImpl{interpolatedMessage='Cannot be empty', propertyPath=alternatives, rootBeanClass=class game.Question, messageTemplate='{org.hibernate.validator.constraints.NotEmpty.message}'}
]
</code></pre>
<p>[Edit] If I deliberately leave something blank it does show the validation error and doesn't try to <code>merge()</code>, so validations are being run as expected.</p>
<p>I've checked the whole thing manually and there really are no errors. Used this "alternative" method to check and print validation errors:</p>
<pre><code>private void val(final Object obj, final String s) {
final ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
final javax.validation.Validator validator = factory.getValidator();
final Set<ConstraintViolation<Object>> constraintViolations = validator.validate(obj);
for (final ConstraintViolation cv : constraintViolations) {

<p>This is roughly what my add/remove Questions method do:</p>
<pre><code>@Transactional
public void updateQuestions(final String quizId, final List<Question> questions) {
// Quizzes might have slugs (/quiz-name)
final Quiz quiz = findQuizByIdString(quizId);
if (quiz != null) {
for (final Question question : questions) {
question.setQuiz(quiz);
if (question.getAlternatives() != null) {
for (final Alternative alt : question.getAlternatives()) {
alt.setQuestion(question);
}
}
if (question.getId() != null) {
final Question old = (Question) ps.createQuery("FROM Question WHERE id = :id AND quiz = :quiz").setParameter("id", question.getId()).setParameter("quiz", quiz).getSingleResult();
// Making sure the Question do belong to the this Quiz
if (old == null) {
question.setId(null);
}
}
if (question.getId() == null) {
// Set the new question up (who created, timestamp, etc.)
}
}
quiz.setQuestions(questions);
if (!validator.validate(quiz).hasErrors()) {
try {
entityManager.merge(quiz);
} catch (final Exception e) {
if (log.isErrorEnabled()) { log.error("Error while updating Quiz Questions", e); }
}
}
}
else {
// Send an error to the user
}
}
</code></pre>
<p>And finally these are the (what I think) relevant parts of my entities:</p>
<pre><code>@Entity
public class Quiz {

@OneToMany(mappedBy = "quiz", cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = true)

StructureFareRulesRQ Parse Failure - Visual Studio Web Reference Naming Convention Error?
|
<p>I'm trying to call the StructureFareRulesRQ API from Sabre but its seems as though this API is different than the rest of the Sabre APIs. After adding the wsdl file to my project, I am expecting the Web Service call method to be named something like StructureFareRulesRQService but that doesn't exist. Instead I get StructureFareRulesRQ as the actual service and StructureFareRulesRQ1 as the wrapper class for the XML message. As the wrapper class has the wrong name, when it gets serialized, it creates a bogus XML message (see below).</p>
<p>I know I can probably dig through the reference.cs file and do a find/replace, but I'm concerned that doing that will require me to do the same thing whenever a new version comes online. Has anyone else run into this, or am I going nuts? </p>
<p>Example XML Payload which returns a "Error ErrorCode="009400" ErrorMessage="PARSE FAILURE - INVALID REQUEST" response from Sabre:</p>

Apache James Mail Server: Where to put custom Mailets?
|
<p>I want to wite a custom Mailet for the Apache James Mail Server.</p>
<p>I'm running James through Docker via the <code>linagora/james-project</code> image. The setup works (only locally of course, but that's enough for the moment), as I can set up accounts and connect to them with Thunderbird via IMAP and I can send mails between those accounts.</p>
<p>Now I want to deploy my custom Mailet to this setup. I have tried it using this tutorial: <a href="https://james.apache.org/server/3/dev-extend-mailet.html" rel="nofollow noreferrer">https://james.apache.org/server/3/dev-extend-mailet.html</a>
(I had to create the folder /conf/lib/ since it didn't exist) but it won't work. In the Log I see errors like this one:</p>
<pre><code>james | [main] INFO org.apache.james.mailetcontainer.lib.AbstractStateMailetProcessor - Matcher All instantiated.
james | [main] ERROR org.apache.james.mailetcontainer.lib.AbstractStateMailetProcessor - Unable to init mailet com.jeremiaslubberger.mailets.TestMailet: javax.mail.MessagingException: Can not load mailet com.jeremiaslubberger.mailets.TestMailet;
james | nested exception is:

james | javax.mail.MessagingException: Can not load mailet com.jeremiaslubberger.mailets.TestMailet;
james | nested exception is:
james | java.lang.ClassNotFoundException: com.jeremiaslubberger.mailets.TestMailet
</code></pre>
<p>By searching the source code, I found the file <code>ExtendedClassLoader.java</code> where there is a line
<code>public static final String EXTENSIONS_JARS_FOLDER_NAME = "extensions-jars/";</code>
So I tried creating this folder (in the James root folder) and putting the JAR containing the custom Mailet there.</p>
<p>This still produces errors and doesn't work, however the Log now looks like this:</p>
<pre><code>james | [main] INFO org.apache.james.mailetcontainer.lib.AbstractStateMailetProcessor - Matcher All instantiated.

</code></pre>
<p>My custom Mailet does extend GenericMailet, but so do all other (default) Mailets. Also, I exported my mailet including all resources, so there should be nothing missing there. Now I'm out of ideas.</p>
<p>Can anyone please help? Where do I need to put the JAR containing my custom Mailet?</p>

@PostConstuct does not appear to work and @autowire gives an error
|
<p>I am new to spring and am creating a spring web application.
The application I'm writing has a <code>Class PreLoadService</code>. In this class is a method defined with <code>@PostConstruct</code> that calls a DAO to load the data. The DAO instance is declared in the class with the <code>@autowired</code>.</p>
<p>The Controller for the JSP then declares an instance of the <code>PreLoadService</code> and calls the getter to retrieve the data that should have been loaded in the <code>@PostConstruct</code>. The data is never loaded and an exception is also thrown on the <code>@autowired</code>.</p>
<p>Since this did not work I tried a simple Hello World version to write a message and received the same issue. I will post this. In the WEB_INF folder I have a <code>web.xml</code> and a <code>spring3-servlet.xml</code>. In the SRC folder I have an <code>applicationContext.xml</code>. I am running on Tomcat 7.</p>

Is there an other way to include Jquery lib to communicate between Angular and this library?
|
<p>I had to include a kind of library called RappidJS and a lot of Jquery files into an Angular 7 Project.
I used an homemade fonction to do it in my component :</p>
<pre><code>ngOnInit() {
this.loadScript('./app/assets/node_modules/jquery/dist/jquery.js');
this.loadScript('./app/assets/node_modules/lodash/index.js');
this.loadScript('./app/assets/node_modules/backbone/backbone.js');
this.loadScript('./app/assets/build/rappid.min.js');
this.loadScript('./app/assets/src/joint.ui.inspector.min.js');
this.loadScript('./app/assets/src/joint.shapes.qad.js');
this.loadScript('./app/assets/src/selection.js');
this.loadScript('./app/assets/src/factory.js');
this.loadScript('./app/assets/src/snippet.js');
this.loadScript('./app/assets/src/app.js');
this.loadScript('./app/assets/src/index.js');
}
public loadScript(url: string) {
const body = <HTMLDivElement>document.body;
const script = document.createElement('script');
script.innerHTML = '';
script.src = url;
script.async = false;
script.defer = true;
body.appendChild(script);
}
</code></pre>
<p>The JS execute fine and my app shows up without any problem. However i need to communicate with some functions in "app.js" to retrieve some json and use it into my angular app.</p>
<p>In my component.html i have a toolbar :</p>
<pre><code> <div id="toolbar">
<button class="btn btn-secondary add-question">Ajouter Question</button>
<button class="btn btn-secondary add-answer">Ajouter Réponse</button>
<button class="btn btn-secondary add-API">Ajouter module API</button>
<button class="btn btn-success add-APIEX">Ajouter module Ping</button>
<button class="btn send-json">Envoyer JSON</button>
<button class="btn btn-secondary preview-dialog">Lancer dialogue</button>
<button class="btn btn-secondary code-snippet">Code Snippet</button>
<button class="btn btn-secondary clear">Effacer Tableau</button>
<button class="btn btn-secondary load-example">Charger le JSON</button>
</div>
and in app.js i have this :
events: {
'click #toolbar .add-question': 'addQuestion',
'click #toolbar .add-API': 'addAPI',
'click #toolbar .add-APIEX': 'addAPIEX',
'click #toolbar .add-answer': 'addAnswer',
'click #toolbar .send-json': 'sendJson',
'click #toolbar .preview-dialog': 'previewDialog',
'click #toolbar .code-snippet': 'showCodeSnippet',
'click #toolbar .load-example': 'loadExample',
'click #toolbar .clear': 'clear'
},
</code></pre>
<p>sendJson: function() {}</p>
<p>I really would like to know is there is a way to communicate between these ?</p>
<p>Thanks </p>

How to add significance of Tukey's test to ggplot2 figure with multiple facet?
|
<p>I generated a plot using a long format table, ggplot() and facet_wrap() functions in Rstudio. I want to add values of Tukey's tests applied to different levels of data and annotated with a system of stars (or letters) for significance.</p>
<p>Here is the example code :</p>
<pre><code># create a df for example
a <- paste0("Sample_", rep(1:100, 1))
b <- c(rep("Dubai", 30), rep("London", 35), rep("Bucarest", 35))
c <- c(rep("Sun", 16), rep("Rain", 16), rep("Cloud", 17), rep("Thunder", 16), rep("Star", 35))
d <- runif(n = 100, min = 0.5, max = 50)
e <- runif(n = 100, min = 0.5, max = 50)
f <- runif(n = 100, min = 0.1, max = 3)
df <- data.frame("Sample"= a, "Location"=b, "Obs"=c, "Measure1"=d, "Measure2"=e, "Measure3"=f)
# convert df to long format
long <- reshape2::melt(df, id.vars = c("Sample", "Location", "Obs"), measure.vars = c("Measure1", "Measure2", "Measure3"))
# make a plot
p <- ggplot(long,aes(Location,value, color=Obs)) +
facet_wrap(~ variable, drop=T, scale="free")+
geom_boxplot(outlier.colour = NA, alpha=0.8, position = position_dodge2(width=1, preserve="single"))+
geom_point(size=1.2, aes(shape=Obs), position=position_dodge(width=0.7, preserve='total'))+
scale_shape_manual("Obs", values = c(16,17,17,16,16),
labels = c("Sun",
"Rain",
"Cloud",
"Thunder",
"Star"))+
scale_color_manual("Obs",
values=c("#00BF7D", "#5B6BF7", "#00B0F6", "#A3A500", "#F8766D"),
labels = c("Sun",
"Rain",

labs(x="Location", y = "Measure")+

React Router v6 Redirects
|
<p>thank you for taking the time to review this question in advance. I have experience with v5 but since changed pretty significantly in v6 I'm quite confused on how to setup a redirect within a nested page.</p>
<p>For example my page structure is as follows:</p>
<pre><code>- /auth
- /client
- dashboard
- settings
- profile
- password
</code></pre>
<p>In my <code>/client</code> route i have a redirect set as follows (where <code>APP_URL = /client</code>:</p>
<pre><code><Route path="/*" element={<Navigate to={`${APP_URL}/dashboard`} />} />
</code></pre>
<p>However, within my <code>/settings</code> route i would like to have it so that <code>/settings</code> redirects to <code>/settings/profile</code>. When setting a redirect within a nested route that also has a redirect it appears to cause an endless loop or redirect to the redirect set within the parent.</p>
<p><strong>App.tsx</strong></p>
<pre><code>function App() {
return (
<div className="App">
<Router>
<Routes>
<Route path="*" element={<Views />}/>
</Routes>
</Router>
</div>
);
}
</code></pre>
<p><strong>Views</strong></p>
<pre><code>export const Views = () => {
return (
<Routes>
<Route path="*" element={<Navigate to={APP_URL} />} />
<Route path={`${APP_URL}/*`} element={<AppLayout />} />
</Routes>
)
}
</code></pre>
<p><strong>AppLayout</strong></p>
<pre><code>export const AppLayout = () => {
return (
<Content>
<AppViews />
</Content>
)
}
</code></pre>
<p><strong>AppViews</strong></p>
<pre><code>export const AppViews = () => {
return (
<Routes>
<Route
path="/*"
element={<Navigate to={`${APP_URL}/dashboard`} />}
/>
<Route path={`/dashboard`} element={<Dashboard />} />
<Route path={`/settings/*`} element={<Settings />} />
</Routes>
)
}
</code></pre>
<p><strong>Settings</strong></p>
<pre><code>const Settings = () => {
return (
<>
<Routes>
<Route
path="/*"
element={<Navigate to={`${APP_URL}/settings/profile`} />}
/>
<Route path={`/profile`} element={<Profile />} />
<Route path={`/password`} element={<Password />} />
</Routes>
</>
)
}
</code></pre>
<p>Does anyone have any experience with this?</p>

Integrate nodejs into existing docker lamp container
|
<p>I'm currently learning how to use docker. And i have a lamp stack container, including php7.4, apache, mariadb, phpmyadmin. All is working fine. I installed Laravel into this container. It includes all needed php extensions.
(I'm aware of Laravel Sail, for docker learning purposes i prefer not to use Sail. I prefer to use my own container).
One problem i'm facing now is i try to install Laravel Breeze and i need to use npm commands at some point. But i couldn't manage to install nodejs into my container and i can use some help.</p>
<p>This is docker-compose.yml</p>

<p>I'm pulling some variables from .env file and others from several Dockerfiles.</p>
<p>I want to integrate nodejs but not for serious nodejs programming. Only for some Laravel based situations like running 'npm install', 'npm run dev' etc. I won't be needing extra details. And i guess it should run on the same volume with the php image.</p>

custom template with v-if is giving error while using inside li item - vue js
|
<p>I have to display menus in navigation bar. There are multiple menu items(Home, About etc). Some menu items are having submenus(2nd -3rd level). So, i created one directive to show up submenus while hovering over the menu in navigation bar.</p>
<p><strong>Here is my code(old code)</strong> - v-show-sub-menu is the directive</p>
<pre><code><ul class="main__menus">
<li v-show-sub-menu v-if="m.displayMenu==='Y'" v-for="(m, idx) in Menus" class="main__menu" :key="idx"
:class="{'main__menu--selected':chkMenu(m)}" @click="screen.moveMenu(m)">
<div class="main__menu-name">{{getMenuName(m)}}</div>
<ul class="main__menu__second" v-show="!hideSubMenu" :class="secondMenuClasses(m)" @click.stop>
// 2nd - 3rd level menu
</ul>
</li>
</ul>
</code></pre>
<p>It is working fine but as per vue standard i refactored code and remove the v-if from v-for in same li tag. I used custom template syntax to check the menu will be displayed in Navigation bar or not like this below.</p>
<pre><code><ul class="main__menus">
<li v-for="(m, idx) in Menus"
:key="idx"
v-show-menu
class="main__menu"
:class="{'main__menu--selected':chkMenu(m)}"
@click="screen.moveMenu(m)"
>
<template v-if="m.displayMenu ==='Y'">
<div class="main__menu-name">
{{ getMenuName(m) }}
</div>
<ul v-show="!hideSubMenu" class="main__menu__second" :class="secondMenuClasses(m)" @click.stop>
// 2nd - 3rd level children
</ul>
</template>
</li>
</ul>
</code></pre>
<p>Directive</p>
<pre><code>showSubMenu: { // It is showing sub menus while hovering over menus in navigation bar
inserted(el) {
const menu = el.querySelector('.main__menu__second');
el.addEventListener('mouseenter', () => {
const { left, height } = el.getBoundingClientRect();
if (document.querySelector('#menu-area')) {
document.querySelector('#menu-area').appendChild(menu);
}
menu.style.display = 'block';
menu.style.top = `${height}px`;
menu.style.left = `${left}px`;
});
menu.addEventListener('mouseenter', () => {
const { left, height } = el.getBoundingClientRect();
menu.style.display = 'block';
menu.style.top = `${height}px`;
menu.style.left = `${left}px`;
});
el.addEventListener('mouseleave', () => {
menu.style.display = 'none';
});
menu.addEventListener('mouseleave', () => {
menu.style.display = 'none';
});
}
}
</code></pre>
<p>But, It is breaking some where and directive is giving null error and there are css issues also visible. I am using computed property to solve this issue.</p>

I need to make these clouds extend to the left and right and go on forever. (Hard to explain so images are provided with further detail)
|
<p>So I am trying to make a cloud generation script that when going forward, left, or right it generates clouds infinitely.</p>
<p>Here is an example of how it currently is, I would like it to generate clouds when moving left or right infinitely but currently it only generates clouds moving forwards infinitely. Arrows are provided in the example for better understanding. I apologize for not adding a image directly but I am unable to as I am a new user:</p>

Why are HTML links not loading until audio file has been played
|
<p>I am coding a website that has a navigation bar at the top of the page, containing normal, generic HTML5 link elements (using the "a" element):</p>
<pre><code><table id="menuButtonTable">
<tr>
<td>
<a href="/home" class="menuButton">
Home
</a>
</td>
<td>
<a href="/play" class="menuButton">
Play
</a>
</td>
<td>
<a href="/help" class="menuButton">
Help
</a>
</td>
<td>
<a href="/contacts" class="menuButton">
Contacts
</a>
</td>
<td>
</td>
</tr>
</table>
</code></pre>
<p>I also am loading multiple audio files in javascript:</p>
<pre><code>const masterVolume = 0.4;
const breakingSound = new Audio("Sound-Effects/breaking.mp3");
breakingSound.volume = masterVolume;
const buildingSound = new Audio("Sound-Effects/building.mp3");
buildingSound.volume = masterVolume;
const choppingSound = new Audio("Sound-Effects/chopping.mp3");
choppingSound.volume = masterVolume;
const diggingSound = new Audio("Sound-Effects/digging.mp3");
diggingSound.volume = masterVolume;
const diggingSong = new Audio("Sound-Effects/digging-song.mp3");

const waterSound = new Audio("Sound-Effects/water.mp3");
waterSound.volume = masterVolume;
const windSound = new Audio("Sound-Effects/wind.mp3");
windSound.volume = masterVolume;
</code></pre>
<p>For some reason, whenever I click on one of the links at the top of the page, they never load and I am just left with the swirling circle, showing that the page is trying to load, at the top left. However, the links do load after the audio 'windSound' has been played. I have absolutely no clue why this is happening, does anyone know how to fix this strange problem?</p>
<p>Thanks</p>

Webpack + eslint replace source change on linting
|
<p>Running on webpack dev server with a string replacement plugin that does a replacement based <a href="https://github.com/jamesandersen/string-replace-webpack-plugin/blob/master/loader.js#L19" rel="nofollow">on a function</a>. I am finding the value of the replacement overwritten my source file .</p>
<p>My Dev server configuration is this:</p>
<pre><code>const devServer = (options) => {
return {
devServer: {
hot: true,
inline: true,
stats: 'errors-only',
host: options.host,
port: options.port,
historyApiFallback: true
},
plugins: [
new webpack.HotModuleReplacementPlugin({
multiStep: true
})
]
}
}
</code></pre>
<p>The string replacement plugin configuration is:</p>
<pre><code> const constants = (data) => {
return {
module: {
loaders: [
{
test: /\.jsx?$/,
loader: StringReplacePlugin.replace({
replacements:[
{
pattern:/\`CONSTANT_(.*)\`/g,
replacement:(match,p1,offset,string)=>{
console.log('MATCH '+p1)
const keys = p1.split('.')
let current = data
keys.forEach((key)=>{
current = current[key]
})
console.log('Replacing '+p1+' with '+current)
return `'${current}'`
}
}
]
})
}
]
},
plugins: [
new StringReplacePlugin()
]
}
}
</code></pre>
<p>The entry/ouptut values are:</p>
<pre><code>const base = {
entry: {
app: path.resolve(PATHS.app, './index.jsx')
},
output: {
path: PATHS.build,
filename: 'app.js',
publicPath: '/'
},
resolve: {
extensions: ['', '.js', '.jsx', '.json']
}
}
</code></pre>
<p>Is there any reason why webpack dev server would be changing files on source?</p>
<p><strong>EDIT: 1</strong> Added JS part:</p>
<pre><code>const js = (paths) => {
const cacheDir = (process.env.CACHE_DIRECTORY ? process.env.CACHE_DIRECTORY : 'true')
return {
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/,
loaders: [
`babel?cacheDirectory=${cacheDir}`, // presets on .babelrc
'eslint-loader?fix'
],
include: paths
}
]
}
}
}
</code></pre>
<p><strong>Edit 2</strong> The cause seesm to be the eslint-loader?fix, when removed the appropriate behaviour is achieved. Now I am seeking how to prevent that</p>

C# Customising MailAddress.From field not working
|
<p>I am trying to send Emails from my custom address to users using C# and googles smtp service. My problem is that when the when the user receives the message it is displayed <code>admin@customDomain.co.uk <myAddress@gmail.com></code> in the from section of the email.</p>
<p>My problem is that I want the user to see <code>admin@customDomain.co.uk <admin@customDomain.co.uk></code>. Is this possible using the google service? Or should I look at some other option? If so what?</p>
<p>I have tried the answers on <a href="https://stackoverflow.com/questions/2737699/sending-emails-in-asp-net-with-specific-name-instead-of-sender-email">this</a> thread but non worked and I also found this <a href="https://gmail.googleblog.com/2009/07/send-mail-from-another-address-without.html" rel="nofollow noreferrer">google blog post</a> but I cant work out how it can solve my issue</p>
<p><strong>My Code</strong></p>
<pre><code> string SmtpAddress = "smtp.gmail.com";

CodeIgniter News Tutorial - Parse Error
|
<p>I'm following the CodeIgniter tutorial (<a href="http://www.codeigniter.com/user_guide/tutorial/news_section.html" rel="nofollow">http://www.codeigniter.com/user_guide/tutorial/news_section.html</a>), when I get to '<a href="http://www.codeigniter.com/user_guide/tutorial/news_section.html#display-the-news" rel="nofollow">Display the news</a>' it isn't made clear where to add the second code block:</p>
<pre><code>public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
</code></pre>
<p>the only way I can interpret the tutorial, is to add it to the News.php controller.</p>
<pre><code><?php
class News extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['news'] = $this->news_model->get_news();
}
public function view($slug = NULL)
{
$data['news_item'] = $this->news_model->get_news($slug);
if (empty($data['news_item']))
{
show_404();
}
$data['title'] = $data['news_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
}
</code></pre>
<p>when I add it at the end of application/controllers/News.php I get a parse error:</p>
<pre><code>Parse error: parse error in /server/application/controllers/News.php on line 33

<p>if I include it within the News class, I get two PHP errors & a fatal error:</p>

How to convert GA API JSON to Pandas DataFrame

<p>I want to include in df the following params: query info, profileInfo and rows.</p>
<p>So far I've tried accessing json through json_normalize function, but it doesn't convert the response properly :( </p>
<pre class="lang-py prettyprint-override"><code> df_test=json_normalize(traffic_results)
</code></pre>
<p>It produces df with nested dicts</p>
<p>Then I've tried to pass record_path and meta info:</p>
<pre class="lang-py prettyprint-override"><code>df_example=json_normalize(traffic_results, record_path=['rows'], meta=[['query', 'dimensions'], ['query', 'metrics']])
</code></pre>
<p>Get rows and then dimensions and metrics, but it produces an error: </p>
<p>ValueError: Length of values does not match length of index.</p>
<p>But when I pass these args: </p>
<pre class="lang-py prettyprint-override"><code>response_ga_report=json_normalize(traffic_results, record_path=['rows'], meta=[['query' , 'ids'], ['query' , 'dimensions']])

<p>It works ok:</p>

</code></pre>
<p>I'm deeply stuck, have no idea how it can be converted. It's not mandatory to convert the response in DF.</p>

Binding instances during Caliper benchmarks
|
<p>I've recently been tasked with benchmarking some features of our API, and I've been using Caliper to do so. It seems fairly straightforward and is actually quite powerful, I've been following the tutorials here:</p>
<p><a href="https://stackoverflow.com/questions/21341505/how-to-use-caliper-for-benchmarking">How to use caliper</a></p>
<p><a href="https://www.youtube.com/watch?feature=player_embedded&v=Rbx0HUCnF24" rel="nofollow noreferrer">Tutorial from the creator</a></p>
<p>I'm working with Guice in our current app, so when I try to run the benchmark, I make sure to inject the services I need</p>
<p>Provided below is my code. I've tried setting the variables with their own <code>@injected</code> annotation, I've tried initiating them directly (although there's too many dependencies to deal with, and I'd have to initiate them as well). <code>@Parms</code> annotation won't work because I need to have a string type to iterate through (the parms only takes strings, there's documentation of what to do if it's another type, but it needs a <code>.toString</code> type method)</p>
<pre><code>package com.~~~.~~~.api.benchmark;

<p>The question is: at what point should I be doing injections, and how do I go about that? Should I have a wrapper class setup?</p>
<p><strong>Quick Update</strong></p>
<p>I forgot to mention that is part of a DropWizard (0.7.1) application. We use resources and inject them into the environment</p>
<p>Ex:</p>
<pre><code>environment.jersey().register(injector.getInstance(CampaignManagementResource.class));
</code></pre>
<p>These resources contain the services needed to run them, and they are included as @Inject, though we never actually specify a binding anywhere else.</p>
<pre><code>@Inject
private CampaignMetadataService apiCampaignMetadataService;
</code></pre>
<p>Is there something I should adjust for DropWizard, or should I just mock up the services?</p>

<p>UPDATE:</p>
<p>This is the order it goes through the methods:</p>
<pre><code>onRmsChanged
onReadyForSpeech
onError
</code></pre>
<p>onError I get the error code 2, that means Network Error, but I already set the Google Text To speech, I put <code>INTERNET</code> and <code>RECORD_AUDIO</code> permissions in Manifest and I am connected to the internet. I do not understand what is wrong?</p>

Preventing td from getting smaller when content is empty
|
<p>I have the following table structure. I have a table inside a table here.</p>
<p><a href="https://i.stack.imgur.com/NCb3V.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NCb3V.png" alt="enter image description here"></a></p>
<p>My issue is, if the td doesnt contain any text, the full-height gets removed for some reason:</p>
<p><a href="https://i.stack.imgur.com/TxgwF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TxgwF.png" alt="enter image description here"></a></p>
<p>This is my HTML: (mixed with some Razor which isnt really relevant here)</p>
<pre><code><td style="padding:0;margin:0;"class="border border-dark border-dark">
<table class=" table-borderless justify-content-center " cellspacing="20" style="height:100%!important;padding:0;margin:0;">

</td>
}
<td>
</tr>
</table>
</td>
</code></pre>
<p>How can I prevent it from shrinking and keep it at full height if td is empty?</p>

What does Relay use to decide which outputFields to include in a mutation response?
|
<p>I am creating my first React/Relay application by modifying the TODO example. I am to the point where I am adding my own mutation for an object Distributor that has a parameter bookCount. The mutation is called AddBook and simply increases book count by 1. At this point, the mutation executes without error, optimistically increases the bookCount by 1 correctly, but then reverts the model change when it receives the response from the server. I believe this to be because the response from the server mysteriously does not contain any of my specified outputFields.</p>
<p>Here is my mutation:</p>
<pre><code>var GraphQLAddBookMutation = mutationWithClientMutationId({
name: 'AddBook',
inputFields: {
},
outputFields: {
distributor: {
type: GraphQlDistributor,
resolve: () => getDistributor(),
},
},
mutateAndGetPayload: () => {
console.log("Trying to mutate.");
addBook();
return {};
},
});
</code></pre>
<p>It contains the field 'distributor' in outputFields but no 'distributor' data is included in the graphql response.</p>
<p>The graphql response is:</p>
<pre><code>{
"data": {
"addBook": {
"clientMutationId": "0"
}
}
}
</code></pre>
<p>I have verified that the mutateAndGetPayload function DOES get called but the distributor resolve function DOES NOT get called. </p>
<p>I would have expected every field in outputFields to be included in the graphql response, and every resolve function within outputFields to be called to populate the appropriate parameters in the response but this is not the case</p>
<p>This is particularly confusing to me because the generated schema.json DOES include any outputFields that I specify in the AddBookPayload:</p>
<pre><code>{
"kind": "OBJECT",
"name": "AddBookPayload",
"description": null,
"fields": [
{
"name": "distributor",
"description": null,
"args": [],
"type": {

}
},
"isDeprecated": false,
"deprecationReason": null
}
],

How to place buttons correctly in a layout - android
|
<p>In my android app I have three buttons below. The problem I have is that these buttons are too close together and if I try to move one of them away then they all follow.

Nested cfloops with less records than outer loop cause "array index out of range" error
|
<p>I'm very curious why this is happening. I've run into it twice now, and after a ton of googling/so'ing, I haven't found any reason I actually understand. The gist of it:</p>
<p>Query 1: selectContent (6 records; no blanks/nulls etc)</p>
<p>Query 2: selectPricing (5 records; no blanks/nulls etc)</p>
<p>Output: </p>
<pre><code><cfloop query="selectContent">
<section>
#selectContent.h2#
<cfif selectContent.id eq 3>
<cfloop query="selectPricing" group="groupCol">
<table class="pricing">
<thead>
<tr>
<th>#description#</th>
<th>Price</th>
</tr>
</thead>
<tbody>
<cfloop>
<tr>
<td>#selectPricing.description#</td>
<td>#selectPricing.price#</td>
</tr>
</cfloop>
</tbody>
</table>
</cfloop>
</cfif>
#selectContent.content#
</section>
</cfloop>
</code></pre>
<p>This will give the following error: <em>Array index out of range: 5</em></p>
<p>The error only occurs when the second query has less records than the first. Essentially it feels like that first cfloop takes over the loop iteration from that second one and this causes the issue, but also only if you have that third grouped cfloop in there. The entire inner cfloop runs, as is there in the source.</p>
<p>I've come up with two ways to resolve this:</p>
<ul>
<li>do this with cfoutput/group, but that's relatively ugly as it means lots of closing of cfoutputs from other parts of the page. </li>
<li>stick a cfbreak on that third cfloop if the currentRow matches the recordcount.</li>
</ul>
<p><strong>So, two questions:</strong> </p>
<ul>
<li><p>Why is this even happening? </p></li>
<li><p>Should I be using a totally different approach here (the fact that googling/so'ing isn't finding others with this issue certainly seems to imply that...)?</p></li>
</ul>
<p><strong>EDIT</strong>
I've filed this as a Coldfusion bug based on Adam Cameron's feedback below. <a href="https://bugbase.adobe.com/index.cfm?event=bug&id=3820049">Bug #3820049</a> </p>

Set initial values in form passing parameters (kwargs) with view
|
<p>I want to prefill a form with values taken in a table.
First I pass the PK relative to the line where I wan't to get values and build the kwargs list:</p>
<p><strong>views.py</strong></p>
<pre><code>def NavetteToFicheCreateView(request, pk):
navette = Navette.objects.get(id=pk)
ref = navette.id
attribute_set = navette.famille.pk
cost = navette.cost
qty = navette.qty
etat = navette.etat
etat_ebay = navette.etat.etat_ebay
ean = get_last_ean()
form = NavetteToFicheForm(
request.POST,
ref=ref,
attribute_set=attribute_set,
cost=cost,
qty=qty,
etat=etat,
etat_ebay=etat_ebay,
ean=ean,
)
[...]
</code></pre>
<p>then I retrieve the kwargs in the <strong>form.py</strong> and setup my initial values</p>
<p>class NavetteToFicheForm(forms.ModelForm):</p>
<pre><code>def __init__(self, *args, **kwargs):
self.ref = kwargs.pop('ref', 'noref')
self.attribute_set = kwargs.pop('attribute_set', 9999)
self.cost = kwargs.pop('cost', 0)
self.qty = kwargs.pop('qty', 0)
self.etat = kwargs.pop('etat', 0)
self.etat_ebay = kwargs.pop('etat_ebay', 9999)
self.ean = kwargs.pop('ean', 9999)
super(NavetteToFicheForm, self).__init__(*args, **kwargs)
self.fields['ref'].initial = self.ref
self.fields['attribute_set'].initial = self.attribute_set
self.fields['cost'].initial = self.cost
self.fields['qty'].initial = self.qty
self.fields['etat'].initial = self.etat
self.fields['etat_ebay'].initial = self.etat_ebay
self.fields['ean'].initial = self.ean
[...]
</code></pre>
<p>My problem : some fields like "ref" or "attribute_set" are foreignKeys and are not transmitted when i display the form.</p>
<p>For checking my values :</p>
<pre><code>print(self.ref)
print(self.attribute_set)
</code></pre>
<p><strong>output</strong></p>
<pre><code>34
2
noref
9999
</code></pre>
<p>questions :</p>
<ol>
<li><p>Why does the "print" displays 2 couples of values ? This looks like as if the "noref" and "999" are taken in account.</p>
</li>
<li><p>Why if i set manually 34 and 2 values, it works ?</p>
<p>self.fields['ref'].initial = 34
self.fields['attribute_set'].initial = 2</p>
</li>
</ol>
<p>There's maybe a better way of doing this but I don't know it yet .</p>

Self overwriting object tab
|
<p>I'd like to ask you for help. At my current Java programming skills, that are rather basic this problem is magic for me. Let me explain first what was my intention:
I wanted to load data from database to object tab called airportList, and this is tab of Airport objects initialized here:</p>
<pre><code> public void init()
{
System.out.println("Applet inicialization ...");
mysqllink = new MySQLlink();
try {
mysqllink.getConnection();
} catch (SQLException e) {
System.out.println("Not connected!");
e.printStackTrace();
}
allAirportAmount = mysqllink.getNumerOfRows(tabela_lotnisk);
allAirlineAmount = mysqllink.getNumerOfRows(tabela_linii);
allAirplanesAmount = mysqllink.getNumerOfRows(tabela_samolotow);
allConnectionsAmount = mysqllink.getNumerOfRows(tabela_tras);
airportList = new Airport[allAirportAmount]; //Airport object tab
airportList2 = new String[allAirportAmount]; //as a test i put only Airport name from database over here to String tab
airlineList = new String[allAirlineAmount];
airplaneList = new String[allAirplanesAmount];
FlightConnectionFrame frame = new FlightConnectionFrame();
//frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(frameWidth,frameHeight);
frame.setVisible(true);
add(frame);
}
public static MySQLlink mysqllink = new MySQLlink();
public static int allAirportAmount;
public static int allAirlineAmount;
public static int allAirplanesAmount;
public static int allConnectionsAmount;
public static Airport airportList[]; // declaration over here
public static String airportList2[]; // and here as a test
public static String airlineList[];
public static String airplaneList[];
</code></pre>
<p>Ok, and as you can see I have 2x tables, the airportList of Airport objects and airportList2 of String type. In the next piece of code I load data from database into those two tabs at the same time:</p>
<pre><code>public void viewAirportList()
{
String query = "select id_lotniska, nazwa, lokalizacja, oplaty_lotniskowe from " + databaseName + "." + tabela_lotnisk;
Statement stmt = null;
try {
stmt = databaseConnection.createStatement();
ResultSet rs = stmt.executeQuery(query);
int j = 0;
while (rs.next()) {
int id_l = rs.getInt("id_lotniska");
String name = rs.getString("nazwa");
String loc = rs.getString("lokalizacja");
double tax = rs.getDouble("oplaty_lotniskowe");
flight_connections.FCApletCore.airportList[j] = new Airport(id_l, name, loc, tax); // this is where the Airport object is created and put into the AirportList tab
flight_connections.FCApletCore.airportList2[j] = name; // here, as a test - i put only String value of name to AirportList2 tab
j++;
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
if (stmt != null) { try {
stmt.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
</code></pre>
<p>This is how Airport class looks like:</p>
<pre><code>public class Airport {
public Airport(int i, String n, String l, double o)
{
airport_id = i;
airport_name = n;
airport_localization = l;
airport_tax = o;
System.out.println(" > new object created:" + airport_name);
}
public int getAirportId(){return airport_id;}
public String getAirportName(){return airport_name;}
public String getAirportLocalization(){return airport_localization;}
public double getAirportTax(){return airport_tax;}
public static int airport_id;
public static String airport_name;
public static String airport_localization;
public static double airport_tax;
</code></pre>
<p>}</p>
<p>And using 2x FOR's to get what's inside of both tabs in console:</p>
<pre><code>System.out.println("*** Airport objects tab: airportList ***");
for (int i=0; i<flight_connections.FCApletCore.allAirportAmount; i++)
{
System.out.println("airportList[" + i + "]: " + flight_connections.FCApletCore.airportList[i].getAirportName());
}
System.out.println("*** String values tab: airportList2 ***");
for (int i=0; i<flight_connections.FCApletCore.allAirportAmount; i++)
{
System.out.println("airportList2[" + i + "]: " + flight_connections.FCApletCore.airportList2[i]);
}
</code></pre>
<p>result is:</p>
<pre><code>Applet inicialization ...
Connecting database...
Database connected!
loading number of records from database table: lotniska ...

loading number of records from database table: samoloty ...

airportList2[5]: Port lotniczy Berlin-Brandenburg
airportList2[6]: Port lotniczy San Francisco
airportList2[7]: Port lotniczy Tokio-Haneda
</code></pre>
<p>And if you take a look at this, the String tab is OK, and the Airport tab is not since it's loaded only with one - the last of the records from database and both of the tabs are loaded in the two lines of code next to each other, I do not have any code that can somehow change the values of the first tab. To test if the Airport objects are created correctly I added <code>System.out.println</code> with name of object created, and that you can see in results as a correct values. I'll add that I'm running this as the applet, what <code>init()</code> can suggest. </p>
<p>I changed code a little bit to English names but the database values and tables names are Polish, like in the console you can see "Port lotniczy" what means Airport.</p>
