MUI Select - Change Select size
|
<p>whilst using the selects from MUI, I'm struggling to get them working properly using a height and width with 'vh' and 'vw' appropriately and a text-size using 'vh'.</p>
<p>I end up having a proper size for the boxes, but the label text is not centered anymore due to apparently using a 'transform' to offset itself from the top left corner.</p>
<p>Anyway, here's what I have:

why angularjs ng-repeat not working

<p>I am trying out the basics of AngularJS first time. I am trying out ng-repeat first time. However it is not working. </p>
<p>Here is a non working <a href="http://jsfiddle.net/Mahesha999/XPjNy/1/" rel="nofollow">jsfiddle</a>.</p>
<p>I have written the code in single standalone HTML file as follows and also angular.js file resides in the same directory</p>
<pre><code><html ng-app>
<head>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript">
var users = [
{

Oracle APEX - Saving Shuttle Item selections to a new table
|
<p>I have a project I am working on where I am dealing with PARTS and ORDERS. Each ORDER may contain many PARTS and each PART has the possiblity of being on more than one ORDER over the course of its life (though not more than one ACTIVE ORDER at a time). My tables are currently as follows:</p>
<pre><code> PARTS_TABLE
PART_NUMBER varchar2(20)
ASSIGNED_ORDER_NUMBER number(5)
ASSIGNED_ORDER_STATUS varchar2(20)
ORDER_TABLE
ORDER_NUMBER number (5)
ORDER_STATUS varchar2(20)
ORDER_PARTS_LIST varchar2(4000) //Comma delimited list generated by shuttle item.
</code></pre>
<p>This current set up is working for us atm (with the help of this previous question: <a href="https://stackoverflow.com/questions/9024336/oracle-apex-database-trigger-problems-with-referencing-database-columns">Previous Question</a>) but it requires duplicating lots of data in both tables and it does not really allow for a PART being on multiple ORDERS over the course of its life. </p>
<p>What I would like to do is create a cross-reference table between these two tables:</p>
<pre><code> ORDER_PARTS_TABLE
ORDER_NUMBER number(5) (pk1)
PART_NUMBER varchar2(20) (pk2)
ORDER_STATUS varchar2(20)
</code></pre>
<p>Where PART_NUMBER and ORDER_NUMBER create a joint primary key. </p>
<p>My main issue is creating and editing the rows in ORDER_PARTS_TABLE based on the value of a shuttle item. I am able to effectively edit/update with my current set up but in my current set up I am not trying to create rows, I am just referencing the rows in PARTS_TABLE. When a person, using a shuttle item on a form in APEX, adds PARTS to an ORDER new rows should be created in ORDER_PARTS_TABLE i.e.:</p>
<pre><code> ORDER_TABLE
ORDER_NUMBER ORDER_PARTS_LIST ORDER_STATUS
12345 675:342:871:902 ACTIVE
ORDER_PARTS_TABLE
ORDER_NUMBER PART_NUMBER ORDER_STATUS
12345 675 ACTIVE
12345 342 ACTIVE
12345 871 ACTIVE
12345 902 ACTIVE
</code></pre>
<p>And if that order is later edited where a part is removed then the row pertaining to that relationship should either be removed from the ORDER_PARTS_TABLE or have its ORDER_STATUS set to 'REMOVED'</p>
<pre><code> ORDER_TABLE
ORDER_NUMBER ORDER_PARTS_LIST ORDER_STATUS
12345 675:871:902 ACTIVE
either...
ORDER_PARTS_TABLE
ORDER_NUMBER PART_NUMBER ORDER_STATUS
12345 675 ACTIVE
12345 342 REMOVED
12345 871 ACTIVE
12345 902 ACTIVE
or...
ORDER_PARTS_TABLE
ORDER_NUMBER PART_NUMBER ORDER_STATUS
12345 675 ACTIVE
12345 871 ACTIVE
12345 902 ACTIVE
</code></pre>
<p>Does any of that make sense? My current solution is just using triggers which I have been decently happy with but let me know what the best way to approach this new issue is. Thanks!</p>
<p><strong>EDIT:</strong> I have been doing some continued digging and found something that sounds reasonably promising if it can be adapted. Has anyone here had experience with

PHP: Dynamic Drop down with optgroup
|
<p>I am developing a drop down menu that uses HTML optgroups for group names that employees are a part of. Here is the MySQL query and output:</p>
<pre>
mysql> SELECT employees.emp_id,employees.empname,employees.grp_id,groups.groupname FROM employees left join groups on employees.grp_id = groups.grp_id order by groupname asc;
+--------+------------+--------+-----------+
| emp_id | empname | grp_id | groupname |
+--------+------------+--------+-----------+
| 20 | Employee 2 | 13 | Group 1 |
| 19 | Employee 1 | 13 | Group 1 |
| 21 | Employee 3 | 14 | Group 2 |
+--------+------------+--------+-----------+
3 rows in set (0.00 sec)
</pre>
<p>The only issue is, I'm having the hardest time figuring out how to get the optgroup to work correctly. I've tried countless times, and it's really starting to frustrate me. <strong>The following is pretty much I want the output to be (example):</strong></p>
<pre><code><select name="dropdownmenu">
<optgroup label="Group 1">
<option name="20">Employee 2</option>
<option name="19">Employee 1</option>
</optgroup>
<optgroup label="Group 2">
<option name="21">Employee 3</option>
</optgroup>
</select>
</code></pre>
<p>Basically, the optgroup needs to be the "groupname", the option "name" should be the "emp_id", and the action "option" (drop down item) is the "empname".</p>
<p>I hope this is something that can be done, but really not sure. Here's the function I have, but it doesn't exactly work well:</p>
<pre><code>function getDynGrpList() {
global $db;
// $query = "SELECT * FROM employees ORDER BY grp_id desc;";
$query = "SELECT employees.emp_id,employees.empname,employees.grp_id,groups.groupname FROM employees left join groups on employees.grp_id = groups.grp_id order by groupname asc;";
$employees = $db->GetAll($query);
$groups = array();
while ($qa = $employees->GetRows()) {
$groups[$qa['groupname']][$qa['grp_id']] = $qa['empname'];
}
foreach ($groups as $label => $opt) { ?>
<optgroup label="<?php echo $label; ?>">
<?php }
foreach ($groups[$label] as $id => $name) { ?>
<option value="<?php echo $id; ?>"><?php echo $name; ?></option>
<?php } ?>
</optgroup>
<?php }
</code></pre>
<p><strong>getDynGrpList function as of 3:15AM CST (2/27):</strong></p>
<pre><code>function getDynGrpList() {
global $db;
// $query = "SELECT * FROM employees ORDER BY grp_id desc;";
$query = "SELECT employees.emp_id,employees.empname,employees.grp_id,groups.groupname FROM employees left join groups on employees.grp_id = groups.grp_id order by groupname asc;";
$employees = $db->GetAll($query);
$groups = array();
while ($qa = $employees->GetRows()) {
$groups[$qa['groupname']][$qa['emp_id']] = $qa['empname'];
}
var_export($groups);
foreach($groups as $label => $opt): ?>
<optgroup label="<?php echo $label; ?>">
<?php foreach ($opt as $id => $name): ?>
<option value="<?php echo $id; ?>"><?php echo $name; ?></option>
<?php endforeach; ?>
</optgroup>
<?php endforeach;
}
</code></pre>
<p><strong>Final Solution (with the help of Felix Kling)</strong></p>
<pre><code>function getDynGrpList() {
global $db;
$query = "SELECT employees.emp_id,employees.empname,employees.grp_id,groups.groupname FROM employees left join groups on employees.grp_id = groups.grp_id order by groupname asc;";
$employees = $db->GetAll($query);
$groups = array();
foreach ($employees as $employee) {
$groups[$employee['groupname']][$employee['emp_id']] = $employee['empname'];
}
foreach($groups as $label => $opt): ?>
<optgroup label="<?php echo $label; ?>">
<?php foreach ($opt as $id => $name): ?>
<option value="<?php echo $id; ?>"><?php echo $name; ?></option>
<?php endforeach; ?>
</optgroup>
<?php endforeach;

sliding between route transition angularjs

<p>I've only been working with Angular for about a week, so I apologize if my code is crap.</p>
<p>I'm attempting to create a sliding action between route transitions. I can create the effect in a slideshow but not between route transitions.</p>
<p>Anyway code below:
Nav</p>
<pre><code><li><a ng-click="go('/')" class = "intro currentLink navLinks">Intro</a></li>
<li><a ng-click="go('/why')" class = "why navLinks">Why</a></li>
<li><a ng-click="go('/resume')" class = "resume navLinks">Res</a></li>
<li><a ng-click="go('/qualified')" class = "qualified navLinks">How</a></li>
<li><a ng-click="go('/contact')" class = "contact navLinks">Contact me</a></li>

CSS: 100% font size - 100% of what?
|
<p>There are <a href="http://www.alistapart.com/articles/howtosizetextincss" rel="noreferrer">many</a> <a href="http://www.w3.org/TR/CSS2/fonts.html#font-size-props" rel="noreferrer">articles</a> and <a href="https://stackoverflow.com/questions/132685/font-size-in-css-or-em">questions</a> about <a href="http://kyleschaeffer.com/best-practices/css-font-size-em-vs-px-vs-pt-vs/" rel="noreferrer">percentage-sized vs other-sized</a> fonts. However, I can not find out WHAT the reference of the percent-value is supposed to be. I understand this is 'the same size in all browsers'. I also read this, for instance:</p>
<blockquote>
<p>Percent (%): The percent unit is much like the “em” unit, save for a few fundamental differences. First and foremost, the current font-size is equal to 100% (i.e. 12pt = 100%). While using the percent unit, your text remains fully scalable for mobile devices and for accessibility.</p>
</blockquote>
<p>Source: <a href="http://kyleschaeffer.com/best-practices/css-font-size-em-vs-px-vs-pt-vs/" rel="noreferrer">http://kyleschaeffer.com/best-practices/css-font-size-em-vs-px-vs-pt-vs/</a></p>
<p>But if you say "ie 12 pt = 100%", then it means you first have to define <code>font-size: 12pt</code>. Is that how it works? You first define a size in an absolute measure, and then refer to this as '100%'? Does not make a lot of sense, as many samples say it is useful to put:</p>
<pre><code>body {
font-size: 100%;
}
</code></pre>
<p>So by doing this, <em>WHAT</em> is the font size relative to? I notice that the size I see on my screen differs for every font. Arial looks way bigger than Times New Roman, for instance. Also, if I would just do this, body size = 100%, would <em>that</em> mean that it will be the same on all browsers? Or only if I first define an absolute value? </p>
<p><strong>UPDATE, SAT JUL 23</strong></p>
<p>I am getting there, but please bear with me. </p>
<p>So, the % value relates to the default browser font size, if I understand correctly. Well, that is nice but gives me again several other questions:</p>
<ol>
<li>Is this standard size always the same for every browser version, or do they vary between versions?</li>
<li>I ! found (see image below) the settings for Google Chrome (never looked at this before!), and I see standard "serif", "sans-serif" and "monospace" settings. But how do I interpret this for other fonts? Say I define <code>font: 100% Georgia;</code>, what size will the browser take? Will it look up the standard size for serif, or has the "Georgia" font a standard size for the browser</li>
<li>On several websites I <a href="http://www.alistapart.com/articles/howtosizetextincss" rel="noreferrer">read</a> things like <code>Sizing text and line-height in ems, with a percentage specified on the body [..], was shown to provide **accurate, resizable text across all browsers** in common use today</code>. But from what I am learning now I believe that you should actually choose between either resizable text (using % or em, like what they recommend in this quote), or having 'accurate, consistent font-sizes across browsers' (by using px or pt as a base). Is this correct? </li>
</ol>
<p>Google Settings:</p>
<p><img src="https://i.stack.imgur.com/9dR1N.png" alt="Google Chrome Settinsg"></p>
<p>This is how I <em>think</em> things <em>could</em> look like if you do not define the size in absolute values. </p>

Spring Security logout does not work - does not clear security context and authenticated user still exists
|
<p>I know, there are many articles about this topic, but I have a problem and I can't find any solution.</p>
<p>I have a classic spring security java config:</p>
<pre><code>@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
private AuctionAuthenticationProvider auctionAuthenticationProvider;
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(auctionAuthenticationProvider);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.httpBasic();
ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry authorizeRequest = http.authorizeRequests();
configureAdminPanelAccess(authorizeRequest);
configureFrontApplicationAccess(authorizeRequest);
configureCommonAccess(authorizeRequest);
http.csrf()
.csrfTokenRepository(csrfTokenRepository()).and()
.addFilterAfter(csrfHeaderFilter(), CsrfFilter.class);
http.logout()
.clearAuthentication(true)
.invalidateHttpSession(true);
}
...
}
</code></pre>
<p>Also, I have two controller methods, where I login/logout from my web application by AJAX.</p>
<p>When I would like to logout, I first call this method, which I expect to clear user sessions and clear everything from the security context.</p>
<pre><code>@Override
@RequestMapping(value = "/logout", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<Boolean> logout(final HttpServletRequest request, final HttpServletResponse response) {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (auth != null){
new SecurityContextLogoutHandler().logout(request, response, auth);
}
return new ResponseEntity<>(Boolean.TRUE, HttpStatus.OK);
}
</code></pre>
<p>After this I reload my client web application and each time, when it is reloaded, I check whether the user is authenticated by calling the following controller method:</p>
<pre><code>@Override
@RequestMapping(value = "/user", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<UserDetails> user() {
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
if (principal instanceof UserDetails) {
return new ResponseEntity<>((UserDetails) principal, HttpStatus.OK);
}
return null;
}
</code></pre>
<p>And here I aways receive the last authenticated user. It seems that in the previous logout method, Spring logout doesn't work.</p>
<p>Keep in mind that I tried to logout with the following code, without any success:</p>
<pre><code> @Override
@RequestMapping(value = "/logout", method = GET, produces = APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<Boolean> logout(final HttpServletRequest request) {
try {
request.logout();
return new ResponseEntity<>(Boolean.TRUE, HttpStatus.OK);
} catch (ServletException ex) {
if (LOG.isDebugEnabled()) {
LOG.debug("There is a problem with the logout of the user", ex);
}
}
</code></pre>
<p>Are you have any idea what I miss in my config and the logout process?</p>

Angular get offset of element by id
|
<p>I try to set the navbar li object to active when i currently watch the corresponding section.
In other words: When scrolling through my page (single page with multiple sections), the section i'm watching should be highlighted in the navbar.</p>
<p>I already got the scrolling position via directive. Where I fail is to trigger ng-class on the .nav ul li.</p>
<pre><code><li class="" ng-class="{'active': $parent.scrollPos > document.getElementById('something').offset()}">
<a class="" ng-click="isCollapsed = true" href="#something" du-smooth-scroll>Something</a>
</li>
</code></pre>
<p>I doesn't make any difference when I use </p>
<pre><code>ng-class="{'active': $parent.scrollPos > angular.element('#something').offset()}"
</code></pre>
<p>How do I get the distance from document-top of any element? </p>
<p>Thanks a lot. </p>
<p>PS: I use jQuery (not lite)!</p>
<p><strong>EDIT</strong>
How it works (Thanks to @Sharikov Vladislav):
On body I use the "PageCtrl":</p>
<pre><code><body id="page-top" class="index bg-default" ng-app="previewApp" ng-controller="PageCtrl">
</code></pre>
<p>which looks like that:</p>
<pre><code>angular.module('previewApp')
.controller('PageCtrl', function($scope, $element) {
$scope.scrollPos = 0;
$scope.getOffset = function (elementId) {
var element = $element.find(elementId);
return element.offset().top;
};
});
</code></pre>
<p>Right after the body I use a span </p>
<pre><code><span scroll-position="scrollPos"></span>
</code></pre>
<p>to initialise my "scrollPosition"-directive, which allows me to access the current scroll position over the $scope.scrollPos in PageCtrl.
Directive:</p>
<pre><code>angular.module('previewApp')
.directive('scrollPosition', function ($window) {
return {
scope: {
scrollPos: "=scrollPosition"
},
link: function (scope, element, attrs) {
var windowElement = angular.element($window);
var handler = function () {
scope.scrollPos = windowElement.scrollTop();
}
windowElement.on('scroll', scope.$apply.bind(scope, handler));
handler();
}
};
});
</code></pre>
<p>In my .nav ul li looks like the following. The "- 150" is for a more acurate highlighting. </p>
<pre><code><div class="navbar-collapse" uib-collapse="isCollapsed" id="menu-center">
<ul class="nav navbar-nav navbar-right">
<li class="hidden">
<a href="#page-top"></a>
</li>
<li ng-class="{'active': $parent.scrollPos > $parent.getOffset('#section1') - 150 && $parent.scrollPos < $parent.getOffset('#section2') - 150}">
<a ng-click="isCollapsed = true" href="#section1" du-smooth-scroll>Section1</a>
</li>
<li ng-class="{'active': $parent.scrollPos > $parent.getOffset('#section2') - 150 && $parent.scrollPos < $parent.getOffset('#section3')}">
<a ng-click="isCollapsed = true" href="#section2" du-smooth-scroll>Section2</a>
</li>
</ul>
</div>
</code></pre>
<p>I hope this helps somebody out there who is struggling over the same problem like me. Greets</p>

How to create XML file on server using stored procedure or cursor
|
<p>In my database (<code>GoogleSEOData</code>), I have got one Table (GoogleMarkupList) and below sample data are there in table:</p>
<pre><code>PUBLICATION_ID | PAGEID | URL
-------------------------------------------------------------
233 | 654345 | /english/index.aspx
345 | 654345 | /de/english/index.aspx
432 | 654345 | /ru/russian/index.aspx
533 | 654345 | /ae/arabic/index.aspx
233 | 452323 | /english/offers.aspx
345 | 452323 | /de/english/offers.aspx
432 | 452323 | /ru/russian/offers.aspx
533 | 452323 | /ae/arabic/offers.aspx
233 | 834343 | /english/destinations.aspx
345 | 834343 | /de/english/destinations.aspx
432 | 834343 | /ru/russian/destinations.aspx
533 | 834343 | /ae/arabic/destinations.aspx
</code></pre>
<p>Now I want to write SQL Procedure which will take File Path of the server as input say (D://GoogleMarkup) and would create below type of XML files on server (For above sample data).</p>
<p>Name of XML file for 654345 type of data will be <code>654345.XML</code></p>
<pre><code><ps>
<p n="233" u="/english/index.aspx" />
<p n="345" u="/de/english/index.aspx" />
<p n="432" u="/ru/russian/index.aspx" />
<p n="533" u="/ae/arabic/index.aspx" />
</ps>
</code></pre>
<p>Name of XML file for 452323 type of data will be <code>452323.XML</code></p>
<pre><code><ps>
<p n="233" u="/english/offers.aspx" />
<p n="345" u="/de/english/offers.aspx" />
<p n="432" u="/ru/russian/offers.aspx" />
<p n="533" u="/ae/arabic/offers.aspx" />
</ps>
</code></pre>
<p>Name of XML file for 834343 type of data will be <code>834343.XML</code></p>
<pre><code><ps>
<p n="233" u="/english/destinations.aspx" />
<p n="345" u="/de/english/destinations.aspx" />
<p n="432" u="/ru/russian/destinations.aspx" />
<p n="533" u="/ae/arabic/destinations.aspx" />
</ps>
</code></pre>
<p>I know there is utility </p>
<pre><code>SQLCMD -S Server -d Database -E -v pageid=%pid%
-Q "Select publication_id as [n], url from table as [p] where pageid=$(pageid) for xml auto, root('ps')"
-o D://GoogleMarkup/%pid%.xml
</code></pre>
<p>But how to create all the XMLs in one go, so that it will read pageid one by one and would pass to <code>SQLCMD</code> to create XML, do I need to write cursor for that, please suggest with some good code sample. </p>
<p>Please suggest!! </p>

Convert Linkedlist to ArrayList

How to have Keycloak login page in iframe?

How to click a button through coding?

Get all rows matching a list in a SQL query
|
<p>I have the following SQL query that selects any row matching ANY of the values in the list (9, 10):</p>
<pre><code>SELECT
r.id, r.title,
u.name as 'Created By',
c.name as 'Category',
c.value,
cr.category_id
FROM
category_resource cr
INNER JOIN resource r
ON cr.resource_id = r.id
INNER JOIN user u
ON r.created_by = u.id
INNER JOIN category c
ON cr.category_id = c.id
WHERE cr.category_id IN ('10', '9');
</code></pre>
<p>I have tried finding out how to do the opposite, which I also need, i.e select rows that match ALL values.</p>
<p>I have read about using a statement sort of like this:</p>
<pre><code>SELECT
r.id, r.title
FROM
resource r
WHERE
id IN (
SELECT
resource_id
FROM
category_resource
WHERE
category_id IN (9, 10)
GROUP BY
resource_id
HAVING
COUNT(DISTINCT category_id) = 2
);
</code></pre>
<p>This is my attempt at adapting this answer to my needs:
<a href="https://stackoverflow.com/questions/15977126/sql-server-select-rows-that-match-all-items-in-a-list">SQL Server - select rows that match all items in a list</a></p>
<p>But that doesn't get me as much information back in the results as the first statement does. So how could I do something that is more equivalent? I've tried to put it together, but I'm too new to SQL to figure it out right, I just get errors...</p>
<p>LONG UPDATE: </p>
<p>Gordon Linoff pointed out that this is a strange request. And I know, I feel that it’s strange too, to have a query that returns multiple rows for the same resource. But I don’t know how to do this any other way, maybe I’m on the wrong track altogether, because it just hit me that the original request (the one getting all rows for resources with categories matching ANY in the list) does quite not fulfill my requirement either…</p>
<p>Here’s my requirement as a whole:</p>
<p>First of all, I think the model of this part of the db might be helpful.</p>
<p><img src="https://i.stack.imgur.com/clxX8.png" alt="enter image description here"></p>
<p>(BTW category has a relation with itself also because it is stored as a hierarchy, using the adjacency model, where each category stores its parent id, if anyone was wondering about that arrow...)</p>
<p>1: Find all resources where a category matches ANY of the values in the list. But (this is where that was insufficient) for each of these resources, I need to know the resource along with all of the categories it has…</p>
<p>Let me explain the point of this with a simple example:</p>
<p>This is a many to many relationship as you can see. A resource (e.g let’s say with the title ”Introduction to carpentry in 18th century New England”) can be associated with many categories (e.g category.name = ”subject” value = ”Carpentry”, category.name=”subject” value = ”Wood”, category.name=”subject” value = ”New England”, category.name=”subject” value = ”History”). Note that this example is simplified, but you see the basic idea.</p>
<p>Now, if a user searches for a resource matching ANY of the categories ”Carpentry” and ”Painting”, the resource ”Introduction to carpentry in 18th century New England” should show up in the results, since one of its categories matched. But, here’s the rub, and why Gordon felt my request was strange: in the search result I want to present to the user, I want to list the title ”Introduction to carpentry in 18th century New England” along with a column showing all the categories that title is classified with, even though the user didn’t search for them - in order to give a better overview of the complete subject matter of this resource.</p>
<p>So how can I do that? The only way I could think of was the first statement in my question, but as I said it just hit me that it doesnt’ give me all categories a resource might have, only the ones actually searched for… </p>
<p>Of course I could do a query for the results first, only getting one row for each. And then do a second query, finding all categories for each resource in the results. But if the first query gives me 1000 results (which will be common), then to get the categories for all of these I would have to do 1000 queries to get the categories for each… Sounds like that would give me performance issues… </p>
<p>Am I thinking about this the wrong way? Is there another way to accomplish what I want to do? I.e give me the resources the query selects, along with all of that resource’s associated categories...</p>
<p>2: Well, after that long explanation, the second requirement is simpler to explain: again the same thing about getting all categories back for a resource selected, but this time the selection in the query should only get those resources that match ALL of the provided values. However, just because I provide all of the values in the query again doesn’ mean that I already have all the categories, since each resource in the results may actually have more (and other) categories and I need those too when presenting the results as mentioned in the first (ANY) requirement.</p>

AlertDialog do not show positive and negative button
|
<p>I used AlertDialog to alert user confirm delete. I check on my device (Android 5.1) and it show well</p>
<p><a href="https://i.stack.imgur.com/c6WhP.png" rel="noreferrer"><img src="https://i.stack.imgur.com/c6WhP.png" alt="enter image description here"></a></p>
<p>But on some another device (also run Android 5.1), the dialog missed positive and negative button.</p>
<p><a href="https://i.stack.imgur.com/b5psH.png" rel="noreferrer"><img src="https://i.stack.imgur.com/b5psH.png" alt="enter image description here"></a></p>
<p>I checked and found that devices happen this issue have a medium resolution (960x540, 854x480). </p>
<p>Is resolution relate with this issue ?
If not, can you tell me the reason and how to fix this issue ?</p>
<p>My code for display dialog:</p>
<pre><code> public static final Dialog yesNoDialog(Context context,

AlertDialog.Builder builder = new AlertDialog.Builder(context,R.style.todoDialogLight);
builder.setTitle(context.getString(R.string.app_name))

return builder.create();
}

Counting number of SELECTED rows in Oracle with PHP
|
<p>I'm doing this project for university, which is basically a movie database and for a couple of queries I need to know how many rows were selected. For now, there's 2 situations where I need this:</p>
<ul>
<li>Display a <strong>single movie</strong> information. I want the count of selected rows to know if the database contains the selected movie by the user. <em>Or is there a better solution for this?</em></li>
<li>That selected movie has genres, I need to know how many so that I can construct a string with the genres separated by <code>|</code> without adding one to the end of the string.</li>
</ul>
<p>With MySQL this is easy, I just query the database and use <code>mysql_num_rows()</code> but <code>oci_num_rows()</code> doesn't work quite the same for the SELECT statement.</p>
<p>The only solution I found with OCI/PHP is this:</p>
<pre><code>if(is_numeric($mid) && $mid > 0) {
$stid = oci_parse($db,
'SELECT COUNT(*) AS NUM_ROWS
FROM movies
WHERE mid = '.$mid
);
oci_define_by_name($stid, 'NUM_ROWS', $num_rows);
oci_execute($stid);
oci_fetch($stid);
if($num_rows > 0) {
$stid = oci_parse($db,
'SELECT title, year, synopsis, poster_url
FROM movies
WHERE mid = '.$mid
);
oci_execute($stid);
$info = oci_fetch_assoc($stid);
$stid = oci_parse($db,
'SELECT COUNT(*) AS NUM_ROWS
FROM genres g, movies_genres mg
WHERE mg.mid = '.$mid.' AND g.gid = mg.gid'
);
oci_define_by_name($stid, 'NUM_ROWS', $num_rows);
oci_execute($stid);
oci_fetch($stid);
$stid = oci_parse($db,
'SELECT g.name AS genre
FROM genres g, movies_genres mg
WHERE mg.mid = '.$mid.' AND g.gid = mg.gid');
oci_execute($stid);
$genres_list = null;
while($row = oci_fetch_assoc($stid)) {
$genres_list .= $row['GENRE'];
if($num_rows > 1) {
$genres_list .= ' | ';
$num_rows--;
}
}
$Template->assignReferences(array(
'Index:LinkURI' => $link_uri,
'Movie:Title' => $info['TITLE'],
'Movie:Year' => $info['YEAR'],
'Movie:GenresList' => $genres_list,
'Movie:Synopsis' => $info['SYNOPSIS'],
'Movie:PosterURL' => $info['POSTER_URL'] // FIX: Handle empty poster link
));
$Template->renderTemplate('movieinfo');
} else {
// TODO: How to handle this error?
}
} else {
// TODO: How to handle this error?
}
</code></pre>
<p>But I don't like it. I always need to make 2 queries to count the rows and then select the actual data and there's too many lines of code just to count the rows.</p>
<p>This code doesn't show it (haven't done it yet cause I'm looking for a better solution) but I'll also need to do the same for the movie directors/writers.</p>
<p>Is there any better and <strong>simpler</strong> solution to accomplish this or this is the only way?</p>
<p>I could add separators in the fetch loop until it finishes and then use PHP functions to trim the last separator from the string, but for this project I'm forced to use SEQUENCES, VIEWS, FUNCTIONS, PROCEDURES and TRIGGERS. Do any of these help solving my problem?</p>
<p>I know what SEQUENCES are, I'm using them already but I don't see how can they help.</p>
<p>For VIEWS, they probably wouldn't simplify the code that much (<em>it's basically a stored query right?</em>). For FUNCTIONS, PROCEDURES and TRIGGERS, as far as I understand them, I can't see how can they be of any help either.</p>
<p>Solutions?</p>

Multi-Schema Privileges for a Table Trigger in an Oracle Database
|
<p>I'm trying to write a table trigger which queries another table that is outside the schema where the trigger will reside. Is this possible? It seems like I have no problem querying tables in my schema but I get:</p>
<pre><code>Error: ORA-00942: table or view does not exist
</code></pre>
<p>when trying trying to query tables outside my schema.</p>
<p><strong>EDIT</strong></p>
<p>My apologies for not providing as much information as possible the first time around. I was under the impression this question was more simple.</p>
<p>I'm trying create a trigger on a table that changes some fields on a newly inserted row based on the existence of some data that may or may not be in a table that is in another schema.</p>
<p>The user account that I'm using to create the trigger does have the permissions to run the queries independently. In fact, I've had my trigger print the query I'm trying to run and was able to run it on it's own successfully. </p>
<p>I should also note that I'm building the query dynamically by using the EXECUTE IMMEDIATE statement. Here's an example:</p>
<pre><code>CREATE OR REPLACE TRIGGER MAIN_SCHEMA.EVENTS
BEFORE INSERT
ON MAIN_SCHEMA.EVENTS REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
DECLARE
rtn_count NUMBER := 0;
table_name VARCHAR2(17) := :NEW.SOME_FIELD;
key_field VARCHAR2(20) := :NEW.ANOTHER_FIELD;
BEGIN
CASE
WHEN (key_field = 'condition_a') THEN
EXECUTE IMMEDIATE 'select count(*) from OTHER_SCHEMA_A.'||table_name||' where KEY_FIELD='''||key_field||'''' INTO rtn_count;
WHEN (key_field = 'condition_b') THEN
EXECUTE IMMEDIATE 'select count(*) from OTHER_SCHEMA_B.'||table_name||' where KEY_FIELD='''||key_field||'''' INTO rtn_count;
WHEN (key_field = 'condition_c') THEN
EXECUTE IMMEDIATE 'select count(*) from OTHER_SCHEMA_C.'||table_name||' where KEY_FIELD='''||key_field||'''' INTO rtn_count;
END CASE;
IF (rtn_count > 0) THEN
-- change some fields that are to be inserted
END IF;
END;
</code></pre>
<p>The trigger seams to fail on the EXECUTE IMMEDIATE with the previously mentioned error.</p>
<p><strong>EDIT</strong></p>
<p>I have done some more research and I can offer more clarification.</p>
<p>The user account I'm using to create this trigger is not MAIN_SCHEMA or any one of the OTHER_SCHEMA_Xs. The account I'm using (ME) is given privileges to the involved tables via the schema users themselves. For example (USER_TAB_PRIVS):</p>
<pre><code>GRANTOR GRANTEE TABLE_SCHEMA TABLE_NAME PRIVILEGE GRANTABLE HIERARCHY
MAIN_SCHEMA ME MAIN_SCHEMA EVENTS DELETE NO NO
MAIN_SCHEMA ME MAIN_SCHEMA EVENTS INSERT NO NO
MAIN_SCHEMA ME MAIN_SCHEMA EVENTS SELECT NO NO
MAIN_SCHEMA ME MAIN_SCHEMA EVENTS UPDATE NO NO
OTHER_SCHEMA_X ME OTHER_SCHEMA_X TARGET_TBL SELECT NO NO
</code></pre>
<p>And I have the following system privileges (USER_SYS_PRIVS):</p>
<pre><code>USERNAME PRIVILEGE ADMIN_OPTION
ME ALTER ANY TRIGGER NO
ME CREATE ANY TRIGGER NO
ME UNLIMITED TABLESPACE NO
</code></pre>
<p>And this is what I found in the Oracle documentation:</p>
<blockquote>
<p>To create a trigger in another user's
schema, or to reference a table in
another schema from a trigger in your
schema, you must have the CREATE ANY
TRIGGER system privilege. With this
privilege, the trigger can be created
in any schema and can be associated
with any user's table. In addition,
the user creating the trigger must
also have EXECUTE privilege on the
referenced procedures, functions, or
packages.</p>
</blockquote>
<p>Here: <a href="http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14251/adfns_triggers.htm" rel="nofollow noreferrer">Oracle Doc</a></p>
<p>So it looks to me like this should work, but I'm not sure about the "EXECUTE privilege" it's referring to in the doc.</p>

Django Rest Framework - Missing Static Directory
|
<p>I have recently started a Digital Ocean server with a pre-installed Django image on Ubuntu 14.04. I wanted to create an API, and have decided on the Django Rest Framework. I installed the Django Rest Framework exactly according to <a href="http://www.django-rest-framework.org/" rel="noreferrer">http://www.django-rest-framework.org/</a>.</p>

Disable point-of-interest information window using Google Maps API v3

ERR_TOO_MANY_REDIRECTS in backoffice when running Prestashop in Docker

Why Laravel Vite Directive Not Working in My Project?
|
<p>I installed and configured laravel breeze and blade according to the <a href="https://laravel.com/docs/9.x/starter-kits#breeze-and-blade" rel="noreferrer">documentation</a> given by laravel. By default it uses Vite but somehow @vite directive is not working in my project and I don't know what I miss.</p>
<p><strong>tailwind.config.js</strong></p>
<pre><code>const defaultTheme = require('tailwindcss/defaultTheme');
/** @type {import('tailwindcss').Config} */
module.exports = {
content: [
'./vendor/laravel/framework/src/Illuminate/Pagination/resources/views/*.blade.php',
'./storage/framework/views/*.php',
'./resources/views/**/*.blade.php',
],
theme: {
extend: {
fontFamily: {
sans: ['Nunito', ...defaultTheme.fontFamily.sans],
},
},
},
plugins: [require('@tailwindcss/forms')],
};
</code></pre>
<p><strong>vite.config.js</strong></p>
<pre><code>import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
export default defineConfig({
plugins: [
laravel([
'resources/css/app.css',
'resources/js/app.js',
]),
]
});
</code></pre>
<p>The vite is compiling properly my js and css assets:
<a href="https://i.stack.imgur.com/70E9x.png" rel="noreferrer"><img src="https://i.stack.imgur.com/70E9x.png" alt="enter image description here" /></a></p>
<p>I then created a test blade template with <code>@vite</code> directive:</p>
<pre><code><!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="csrf-token" content="{{ csrf_token() }}">
<title>{{ config('app.name', 'Laravel') }}</title>
<!-- Fonts -->
<link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Nunito:wght@400;600;700&display=swap">
<!-- Scripts -->
@vite(['resources/css/app.css', 'resources/js/app.js'])
</head>
<body>
<div class="font-sans text-gray-900 antialiased">
Hello World
</div>
</body>
</html>
</code></pre>
<p>My test route:</p>
<pre><code>Route::get('/nice', function () {
return view('test');
});
</code></pre>
<p>The output below shows that the <code>@vite</code> is not generating the appropriate script and link assets tag:</p>
<p><a href="https://i.stack.imgur.com/WpI6z.png" rel="noreferrer"><img src="https://i.stack.imgur.com/WpI6z.png" alt="enter image description here" /></a></p>
<p>My development environment is homestead, and I have laravel mix alongside since I am slowly upgrading our front-end to vite. I hope somebody here will be able to help me fix the issues and thank you.</p>

WPF Force rebind
|
<p>I have an object that can't inherit DependencyObject OR use NotifyPropertyChanged, and I've binded it to quite a few controls, so when the properties change, I don't want to go to each control and change it's value on the code, so I'm thinking there must be a way to tell the XAML to "Rebind" all that it's bound to with one or two lines of code, instead of going:</p>
<pre><code>label1.Content = myObject.DontNotifyThis;
label2.Content = myObject.DontNotifyThisEither;
label3.Content = myObject.DontEvenThinkOfNotifyingThis;
label4.Content = myObject.NotSoFastPal;
</code></pre>
<p>So on, so forth...</p>
<p>This is an oversimplified example:</p>
<p>XAML:</p>
<pre><code><Window x:Class="StackOverflowTests.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" x:Name="window1" Height="300" Width="300" Loaded="window1_Loaded">
<Grid x:Name="gridMain">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Label Grid.Row="0" Content="{Binding Status}" ContentStringFormat="Today's weather: {0}" />
<Label Grid.Row="2" Content="{Binding Temperature}" ContentStringFormat="Today's temperature: {0}" />
<Label Grid.Row="1" Content="{Binding Humidity}" ContentStringFormat="Today's humidity: {0}" />
</Grid>
</Window>
</code></pre>
<p>C#:</p>
<pre><code>using System.Windows;
namespace StackOverflowTests
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
Weather weather = new Weather("Cloudy", "60F", "25%");
public Window1()
{
InitializeComponent();
this.DataContext = weather;
}
private void window1_Loaded(object sender, RoutedEventArgs e)
{
weather.Status = "Sunny";
weather.Temperature = "80F";
weather.Humidity = "3%";
}
}
class Weather
{
public string Status { get; set; }
public string Temperature { get; set; }
public string Humidity { get; set; }
public Weather(string status, string temperature, string humidity)
{
this.Status = status;
this.Temperature = temperature;
this.Humidity = humidity;
}
}
}
</code></pre>
<p>I found a way to do it, but it's not elegant at all, and unfortunatelly, I can't just set the DataContext to a new instance of weather, it needs to be the SAME reference (that's why I set it to null so it changes):</p>
<pre><code>private void window1_Loaded(object sender, RoutedEventArgs e)
{
weather.Status = "Sunny";
weather.Temperature = "80F";
weather.Humidity = "3%";
// bad way to do it
Weather w = (Weather)this.DataContext;
this.DataContext = null;
this.DataContext = w;
}
</code></pre>
<p>Thanks in advance!</p>

Access the Repeater.Item.Count value within a codebehind method
|
<p>I have a repeater on my page:</p>
<pre><code><asp:Repeater id="attachmentsRepeater" runat="server">
<HeaderTemplate>
<%
if (attachmentsRepeater.Items.Count > 0) {
if (attachmentsRepeater.Items.Count == 1) {
Response.Write("<h3>Attachment</h3>");
Response.Write("<p>");
} else {
Response.Write("<h3>Attachments</h3>");
Response.Write("<ul>");
}
}
%>
</HeaderTemplate>
<ItemTemplate>
<%# OutputAttachment(Container)%>
</ItemTemplate>
<FooterTemplate>
<%
if (attachmentsRepeater.Items.Count > 0) {
if (attachmentsRepeater.Items.Count == 1) {
Response.Write("</p>");
} else {
Response.Write("</ul>");
}
}
%>
</FooterTemplate>
</asp:Repeater>
</code></pre>
<p>The original ItemTemplate code looked like this:</p>
<pre><code><ItemTemplate>
<%
if (attachmentsRepeater.Items.Count > 0) {
if (attachmentsRepeater.Items.Count > 1) {
Response.Write("<li>");
}
%>
<a href="<%# DataBinder.Eval(Container.DataItem, "location") %>">
<%# DataBinder.Eval(Container.DataItem, "name") %>
</a>
<%
if (attachmentsRepeater.Items.Count > 1) {
Response.Write("<li>");
}
}
%>
</ItemTemplate>
</code></pre>
<p>In the codebehind, I would like to access the number of Items in the Repeater (line 4):</p>
<pre><code>public string OutputAttachment(RepeaterItem Container) {
string returnValue = "";
Repeater ContainerParent = (Repeater)Container.Parent;
if (attachmentsRepeater.Items.Count > 0) {
if (attachmentsRepeater.Items.Count > 1) {
returnValue += "<li>";
}
returnValue += "<a href=\"" + DataBinder.Eval(Container.DataItem, "location");
if (DataBinder.Eval(Container.DataItem, "location").ToString().EndsWith("/")) {
returnValue += DataBinder.Eval(Container.DataItem, "name");
}
returnValue += ">" + DataBinder.Eval(Container.DataItem, "name") + "</a>";
if (attachmentsRepeater.Items.Count > 1) {
returnValue += "</li>";
}
}
return returnValue;
}
</code></pre>
<p>The code that is output is</p>
<pre><code><h3>Attachment</h3>
<p> </p>
</code></pre>
<p>From this output I know that Item.Count == 1 since there is output, the H3 is singular and there is a P tag. If Item.Count > 1, H3 would be plural and there would be a UL tag.</p>
<p>Is this codebehind method being run before the data is bound? Any workarounds for this? Thanks for your help.</p>
<p>This was working for me before, but I had to change it to fulfill a new requirement, which is when it stopped working.</p>

Calling a SQL Server stored procedure with linq service through c#
|
<p>I am new to Linq and trying to convert this SQL Server stored procedure into Linq, I am building a Silverlight business app and need to call on this procedure to return a grid of results. </p>
<p>I have multiple parameters that the users can use to search for particular pieces. They narrow down their search through the UI and when they hit the search button, the code behind takes all the arguments and sends it to my Linq service, which then needs to call on the stored procedure. </p>
<p>Here is the stored procedure.</p>

<p>However, the beginning 'Job' has an error, and says 'could not find an implementation ... 'join' not found' Can anyone help translate? Or offer a better way to call the stored procedure with the code behind? Thanks</p>

Install tesseract/pytesser on Mac OS X
|
<p>I am trying to install this (and additionally pytesser) for osx 10.9 (with anaconda as default python). I have looked around online but I can't get any of the tutorials to work as they all seem to be extinct (homebrew doesn't have a formula for leptonica for instance). I have probably been struggling to install this for the best part of a week with absolutely no luck at all. </p>
<p>Has anyone managed to succeed recently-how did you do it?</p>
<p>Thanks</p>
<p>Edit: Strangely the brew for leptonica has spluttered into life. I have the fairly strange error below.</p>
<pre><code>brew install tesseract
==> Downloading https://bitbucket.org/3togo/python-tesseract/downloads/tesseract
Already downloaded: /Library/Caches/Homebrew/tesseract-3.03-rc1.tar.gz
==> ./configure --prefix=/usr/local/Cellar/tesseract/3.03-rc1
checking for leptonica... yes
checking for pixCreate in -llept... yes
checking leptonica version >= 1.70... configure: error: in `/private/tmp/tesseract- 19Ol/tesseract-3.03':

See `config.log' for more details
READ THIS: https://github.com/Homebrew/homebrew/wiki/troubleshooting
</code></pre>
<p>i.e it is registering the install but still not working. I will check out the config. file as instructed</p>
<p>Edit 2:</p>
<p>Upon trying to import the library in python I get this:</p>
<pre><code>import tesseract
Traceback (most recent call last):

<p>Reason: image not found</p>
<p>To be honest I am a complete amateur with respect to any of this behind the scenes installation and had to google extensively to even get this far. I would be really grateful if someone with a bit of knowledge could shed any light on the obvious things to try, as I feel as though I have exhausted the web looking for solutions and am getting close to considering this library unuseable and attempting to write my own ocr library-100% not a job I am looking forward to. Alternatively, if anyone knows any decent python ocr libraries with decent support/ install mainatenance I would love to know about them (From my google searching I suspect that tesseract is by far the best known, which is why it is so frustrating that the install is so tricky)</p>
<p>I will happily provide any any more info about my system etc to any warrior willing to have a crack at helping with this.</p>
<p>Thanks!</p>

Plot semi transparent contour plot over image file using matplotlib
|
<p>I'd like to plot a transparent contour plot over an image file in matplotlib/pyplot.</p>
<p>Here's what I got so far...</p>
<p>I have a 600x600 pixel square image file <code>test.png</code> that looks like so:</p>
<p><a href="https://i.stack.imgur.com/YTHQg.png" rel="noreferrer"><img src="https://i.stack.imgur.com/YTHQg.png" alt="enter image description here"></a></p>
<p>I would like to plot a contour plot over this image (having the image file be 'below' and a semi-transparent version of the contour plot overlaid) using matplotlib and pyplot. As a bonus, the image would be automatically scaled to fit within the current plotting boundaries. My example plotting script is as follows:</p>
<pre><code>from matplotlib import pyplot

<p>...but I'm not getting the result I want... instead I just see the contour plot part. Something like:</p>
<p><a href="https://i.stack.imgur.com/QXlPf.png" rel="noreferrer"><img src="https://i.stack.imgur.com/QXlPf.png" alt="enter image description here"></a></p>

I can only see TAB2, but no both of them.</p>
<p>It seems that there are no enougth space to show both. So I've tried to get increase the tab height with this </p>
<pre><code>tabs.getTabWidget().getChildAt(1).getLayoutParams().height = 150;

Illegal constructor with EcmaScript 6
|
<p>First of all I would like that say that I don't really know how I can explain what I did on order to get the error mentioned in the title (<code>uncaught TypeError: Illegal constructor</code>). I am using gulpfile in order to compile my Ecmascript 6 to plain Javascript. My gulpfile looks like this:</p>
<pre><code>var gulp = require('gulp');
var concat = require('gulp-concat');
var babel = require('gulp-babel');
gulp.task('compile', function () {
return gulp.src(['resources/assets/js/*.js', 'resources/assets/js/components/*.js'])
.pipe(babel({
presets: ['es2015']
}).on('error', logError))
.pipe(concat('bundle.js'))
.pipe(gulp.dest('public/js'));
});
gulp.task('watch', function () {
gulp.watch('resources/assets/js/**/*', ['compile']);
})
gulp.task('default', ['watch']);
function logError(err) {
console.log(err);
}
</code></pre>
<p>I have a filesystem where all files are concatenated to one file (bundle.js), after being compiled with Babel. </p>
<p>In the browsers console (either Chrome or Firefox), the error appears and it is located in the next line:</p>

}]);
return Dropdown;
}(Node);
</code></pre>
<p>I am not using <code>export default Dropdown</code> because I am not importing modules in other modules (this is not needed because every file is converted to one file, where everything is accessible). </p>
<p>I did some research and the only reason why peoeple got this error was because there was a capital letter where none was allowed. I didn't find anything else about the cause of this error. Does someone have an idea why I get this error? And does someone have a solution?</p>

Angular2 with RequireJS
|
<p>I am having issues getting Angular2 to load correctly when incorporating RequireJS into the application. </p>
<p>For simplicity wise I am using the very simple Hello World Javascript tutorial on the Angular2 located here : <a href="https://angular.io/docs/js/latest/quickstart.html" rel="noreferrer">https://angular.io/docs/js/latest/quickstart.html</a></p>
<p>I have this system working fine using Angular1 but I can't seem to replicate this success using Angular2.</p>
<p>Here is my index.html file:</p>
<pre><code><html>
<head>
<title>Angular 2 QuickStart JS</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 1. Load RequireJS -->
<script type="text/javascript", src="bower_components/requirejs/require.js", data-main="/require.config.js"></script>
</head>
<!-- 3. Display the application -->
<body>
<ireland-product-app>Loading...</ireland-product-app>
</body>
</code></pre>
<p></p>
<p>My require.config.js file:</p>
<pre><code>require([
'assets/requiredPathsAndShim.js'
], function(requirePathsAndShim) {
require.config({
baseUrl: '/',
paths: requirePathsAndShim.paths,
shim: requirePathsAndShim.shim,
/// Kick start app...
deps: ['app/main']
});
</code></pre>
<p>});</p>
<p>I use the requiredPathsAndShim.js file to load all the dependencies I see that are required to start an Angular2 application. Here is the file:</p>
<pre><code>"use strict";
(function(define) {
define([], function() {
return {
waitSeconds : 10000,
paths: {
'shim' : 'node_modules/core-js/client/shim.min',
'zone' : 'node_modules/zone.js/dist/zone',
'Reflect' : 'node_modules/reflect-metadata/Reflect',
'Rx' : 'node_modules/rxjs/bundles/Rx.umd',
'core' : 'node_modules/@angular/core/core.umd',
'common' : 'node_modules/@angular/common/common.umd',
'compiler' : 'node_modules/@angular/compiler/compiler.umd',
'platform-browser' : 'node_modules/@angular/platform-browser/platform-browser.umd',
'platform-dynamic' : 'node_modules/@angular/platform-browser-dynamic/platform-browser-dynamic.umd'
},
shim : {
}
}
});
})(define);
</code></pre>
<p>I then load the 'app/main' file from my 'required.config' file which will load the bootstrap functionality of Angular2:</p>
<pre><code>"use strict";
(function() {
define([
'app/app.component'
], function(app) {
document.addEventListener('DOMContentLoaded', function() {
ng.platformBrowserDynamic.bootstrap(app.AppComponent);
});
});
})();
</code></pre>
<p>The app/app.component file is a file which simply returns my Angular2 component which is passed into the main.js bootstrap function to start the app. this is the file:</p>
<pre><code>"use strict";
(function() {
define([
], function() {
return {
AppComponent : ng.core.Component({
selector : 'ireland-product-app',
template : '<h1>Product App</h1>'
})
.Class({
constructor : function() {}
})
}
});
})();
</code></pre>
<p>I have been playing around with this for a few hours and can't seem to get this working. Can anyone point me in the right direction as to why this isn't working? I have a feeling some shims need to be added into the require.config but I have had no success setting script load dependencies as of yet. </p>
<p>Thanks</p>

Hibernate's 'hbm2ddl.auto' property with value 'create' is not re-creating table
|
<p>I'm working on my <a href="http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html/ch01.html#tutorial-firstapp" rel="nofollow">first simple Hibernate application</a>. The crux of the problem is, I had renamed a member of persistent class (with apt changes to all other parts) and re-run the application. As 'hbm2ddl.auto' property is assigned 'create' value in configuration xml, Hibernate is expected to create new table on every run but, it's not doing so. Following is detailed information:</p>
<p>CLASS: <br></p>
<pre><code> public class Event {
private Long id;
private String title;
private Date date;
public Event() {
// this form used by Hibernate
}
public Event(String title, Date date) {
// for application use, to create new events
this.title = title;
this.date = date;
}
public Long getId() {
return id;
}
private void setId(Long id) {
this.id = id;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
</code></pre>
<p>Event.hbm.xml: <br></p>
<pre><code><hibernate-mapping package="org.hibernate.tutorial.hbm">
<class name="Event" table="EVENTS">
<id name="id" column="EVENT_ID">
<generator class="increment"/>
</id>
<property name="date" type="timestamp" column="EVENT_DATE"/>
<property name="title"/>
</class>
</code></pre>
<p></p>
<p>hibernate.cfg.xml, among others, has following entry: <br></p>
<pre><code><property name="hbm2ddl.auto">create</property>
</code></pre>
<p>MAIN CLASS: <br></p>
<pre><code>public class EventManager {
public static void main(String[] args) {
EventManager mgr = new EventManager();
List events = mgr.listEvents();
for (int i = 0; i < events.size(); i++) {
Event theEvent = (Event) events.get(i);
System.out.println( "Event: " + theEvent.getTitle() + " Time: " + theEvent.getDate() );
}
HibernateUtil.getSessionFactory().close();
}
private List listEvents() {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
List result = session.createQuery("from Event").list();
session.getTransaction().commit();
return result;
} }
</code></pre>
<p>The above code is working as expected. Just to test 'hbm2ddl.auto' property, I had changed 'title' member in Event class to 'title1'. And, updated setter and getter methods and all references (in mapping xml, Event and EventManager class). Complied with no errors. But, when I try to run the application, I see following exception:</p>

JSON schema: Why does "constant" not validate the same way as a single-valued "enum"?
|
<p>I have an object that provides a sort of audit log of versions of an asset. A couple of its properties (<code>versionSource.metadata</code> and <code>versionSource.files</code>) are objects that should validate against one of two schemas, depending on the value of one of their properties. I started off using a constant in my sub-schemas (inside the <code>oneOf</code>, but that was saying that all the the sub-schemas validated (thus breaking the <code>oneOf</code> since more than one validated. Changing it to a single-valued enum worked, though.</p>
<p>Why the difference in validation?</p>
<p>Here's the original schema:</p>
<pre><code>{
"$id": "https://example.com/schemas/asset-version.json",
"title": "Audit log of asset versions",
"$schema": "http://json-schema.org/draft-07/schema",
"type": "object",
"required": [
"assetID",
"version",
"versionSource"
],
"properties": {
"assetID": {
"type": "string"
},
"version": {
"type": "integer",
"minimum": 1
},
"versionSource": {
"type": "object",
"properties": {
"metadata": {
"type": "object",
"oneOf": [
{
"properties": {
"sourceType": { "constant": "client" }
}
},
{
"$ref": "#/definitions/version-source-previous-version"
}
]
},
"files": {
"type": "object",
"oneOf": [
{
"properties": {
"sourceType": { "constant": "upload" },
"sourceID": {

}
}
},

}
}
}
},
"definitions": {
"version-source-previous-version": {
"properties": {
"sourceType": { "constant": "previous-version" },
"sourceID": {
"type": "integer",
"minimum": 1
}
}
}
}
}
</code></pre>
<p>Here's one example document:</p>
<pre><code>{
"assetID": "0150a186-068d-43e7-bb8b-0a389b572379",
"version": 1,
"versionSource": {

"deleted": "2018-09-02T12:10:00.00Z"
}
</code></pre>
<p>And one more:</p>
<pre><code>{
"assetID": "0150a186-068d-43e7-bb8b-0a389b572379",
"version": 2,
"versionSource": {

"lastModified": "2018-09-02T12:10:00.00Z",
"deleted": "2018-09-02T12:10:00.00Z"
}
</code></pre>
<p>Here's the error I get:</p>
<p>Message: JSON is valid against more than one schema from 'oneOf'. Valid schema indexes: 0, 1.
Schema path:
<a href="https://example.com/schemas/asset-version.json#/properties/versionSource/properties/metadata/oneOf" rel="noreferrer">https://example.com/schemas/asset-version.json#/properties/versionSource/properties/metadata/oneOf</a></p>
<p>Since <code>sourceType</code> is a constant in both schemas inside the <code>oneOf</code>, I'm really not sure how my object could possibly be valid against both schemas.</p>
<p>Changing the schema to the following, though, worked:</p>
<pre><code>{

How to get session array data CodeIgniter
|
<p>I'm not quite sure why the username didn't appear on view page if i change the session data into array (i'm new in CodeIgniter). I have <strong><code>auth</code> controller</strong> to make login process:</p>
<pre><code>function index() {
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'username', 'required|trim|xss_clean');
$this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');
if ($this->form_validation->run() == FALSE) {
$this->load->view('Login');
# code...
}
else {
$username = $this->input->post('username');
$password = $this->input->post('password');
$check = $this->M_login->check($username, $password);
// session data
if ($check->num_rows() == TRUE) {
foreach ($check->result() as $value) {
$sess_data['id'] = $value->id;
$sess_data['name'] = $value->name;
$sess_data['username'] = $value->username;
$sess_data['password'] = $value->password;
$sess_data['description'] = $value->description;
$this->session->set_userdata($sess_data);
}
redirect('Dashboard');
}
else {
$this->session->set_flashdata('result_login', '<br>Invalid username or password, try again.');
redirect('Login');
}
</code></pre>
<p>And here is my <strong>dashboard controller</strong>:</p>
<pre><code>public function __construct() {
parent::__construct();
if(!$this->session->userdata('id')){
redirect('login');
}
}
public function index() {
// Dashboard view
$username = $this->session->userdata('username');
$data['username']=$username;
$this->load->view('Dashboard', $data);
}
function logout() {
$this->session->sess_destroy('id');
redirect('login');
}
</code></pre>
<p>With above code, i can get the username on my dashboard view by <code>echo $username</code>. But when i change the session data like this:</p>
<pre><code>if ($check->num_rows() == TRUE) {
foreach ($check->result() as $value) {
// session data
$sess_data = array(
'id' => $value->id,
'username' => $value->username,
'password' => $value->password,
'name' => $value->name,
'description' => $value->description
);
$this->session->set_userdata('log',$sess_data);
}
}
</code></pre>
<p>And <strong>Dashboard controller</strong> changed like this:</p>
<pre><code>if(!$this->session->userdata('id')) {
$getdata= $this->session->userdata('log');
$data['username'] = $getdata['username'];
}
$this->load->view('Dashboard', $data);
</code></pre>
<p>Then the username disappeared from view page. How can i store username in session array and call it in view page. Please share your better suggestions or your experience guys.</p>
<p>Thanks.</p>

Merging Memory Streams to create a http PDF response in c#

<p>I am trying to merge 2 crystal reports into single pdf file and I'm using Itextsharp v5.1.1. But it says the document cannot be opened. It might be corrupted. There are no build errors. but the pdf is malformed and cant be opened. Here is the order I chose to accomplish this.</p>
<ol>
<li>Export the Crystal report to MemoryStream1 in pdf format</li>
<li>Export the second report into MemoryStream2.</li>
<li>Merge the Memory Streams</li>
<li>Send the Streams to Http Output Response as PDF.</li>
</ol>
<p>Here is the Code for each step in the order.</p>
<pre><code> /// Get the Dataset from Stored Procedure for the CSSource Report
dsCS = CSData.GetUSSourceXML(ds_input);
/// Create the Report of type CSsource
rptCS = ReportFactory.GetReport(typeof(CSsource));

Yii2 - Bad Request (#400) Unable to verify your data submission
|
<p>My yii2 application was working fine till yesterday however today on submiting form it is showing error. "Bad Request (#400) Unable to verify your data submission.".</p>

Why is StringBuilder#append(int) faster in Java 7 than in Java 8?
|
<p>While investigating for a <a href="https://stackoverflow.com/q/23748186/507519">little debate</a> w.r.t. using <code>"" + n</code> and <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#toString%28int%29" rel="nofollow noreferrer"><code>Integer.toString(int)</code></a> to convert an integer primitive to a string I wrote this <a href="http://openjdk.java.net/projects/code-tools/jmh/" rel="nofollow noreferrer">JMH</a> microbenchmark:</p>
<pre><code>@Fork(1)
@OutputTimeUnit(TimeUnit.MILLISECONDS)
@State(Scope.Benchmark)
public class IntStr {
protected int counter;
@GenerateMicroBenchmark
public String integerToString() {
return Integer.toString(this.counter++);
}
@GenerateMicroBenchmark
public String stringBuilder0() {
return new StringBuilder().append(this.counter++).toString();
}
@GenerateMicroBenchmark
public String stringBuilder1() {
return new StringBuilder().append("").append(this.counter++).toString();
}
@GenerateMicroBenchmark
public String stringBuilder2() {
return new StringBuilder().append("").append(Integer.toString(this.counter++)).toString();
}
@GenerateMicroBenchmark
public String stringFormat() {
return String.format("%d", this.counter++);
}
@Setup(Level.Iteration)
public void prepareIteration() {
this.counter = 0;
}
}
</code></pre>
<p>I ran it with the default JMH options with both Java VMs that exist on my Linux machine (up-to-date Mageia 4 64-bit, Intel i7-3770 CPU, 32GB RAM). The first JVM was the one supplied with Oracle JDK
8u5 64-bit:</p>
<pre><code>java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
</code></pre>
<p>With this JVM I got pretty much what I expected:</p>
<pre><code>Benchmark Mode Samples Mean Mean error Units
b.IntStr.integerToString thrpt 20 32317.048 698.703 ops/ms
b.IntStr.stringBuilder0 thrpt 20 28129.499 421.520 ops/ms
b.IntStr.stringBuilder1 thrpt 20 28106.692 1117.958 ops/ms
b.IntStr.stringBuilder2 thrpt 20 20066.939 1052.937 ops/ms
b.IntStr.stringFormat thrpt 20 2346.452 37.422 ops/ms
</code></pre>
<p>I.e. using the <code>StringBuilder</code> class is slower due to the additional overhead of creating the <code>StringBuilder</code> object and appending an empty string. Using <code>String.format(String, ...)</code> is even slower, by an order of magnitude or so.</p>
<p>The distribution-provided compiler, on the other hand, is based on OpenJDK 1.7:</p>
<pre><code>java version "1.7.0_55"
OpenJDK Runtime Environment (mageia-2.4.7.1.mga4-x86_64 u55-b13)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)
</code></pre>
<p>The results here were <em>interesting</em>:</p>
<pre><code>Benchmark Mode Samples Mean Mean error Units
b.IntStr.integerToString thrpt 20 31249.306 881.125 ops/ms
b.IntStr.stringBuilder0 thrpt 20 39486.857 663.766 ops/ms
b.IntStr.stringBuilder1 thrpt 20 41072.058 484.353 ops/ms
b.IntStr.stringBuilder2 thrpt 20 20513.913 466.130 ops/ms
b.IntStr.stringFormat thrpt 20 2068.471 44.964 ops/ms
</code></pre>
<p>Why does <code>StringBuilder.append(int)</code> appear so much faster with this JVM? Looking at the <code>StringBuilder</code> class source code revealed nothing particularly interesting - the method in question is almost identical to <code>Integer#toString(int)</code>. Interestingly enough, appending the result of <code>Integer.toString(int)</code> (the <code>stringBuilder2</code> microbenchmark) does not appear to be faster.</p>
<p>Is this performance discrepancy an issue with the testing harness? Or does my OpenJDK JVM contain optimizations that would affect this particular code (anti)-pattern?</p>
<p><strong>EDIT:</strong></p>
<p>For a more straight-forward comparison, I installed Oracle JDK 1.7u55:</p>
<pre><code>java version "1.7.0_55"
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
</code></pre>
<p>The results are similar to those of OpenJDK:</p>
<pre><code>Benchmark Mode Samples Mean Mean error Units
b.IntStr.integerToString thrpt 20 32502.493 501.928 ops/ms
b.IntStr.stringBuilder0 thrpt 20 39592.174 428.967 ops/ms
b.IntStr.stringBuilder1 thrpt 20 40978.633 544.236 ops/ms
</code></pre>
<p>It seems that this is a more general Java 7 vs Java 8 issue. Perhaps Java 7 had more aggressive string optimizations?</p>
<p><strong>EDIT 2</strong>:</p>
<p>For completeness, here are the string-related VM options for both of these JVMs:</p>
<p>For Oracle JDK 8u5:</p>
<pre><code>$ /usr/java/default/bin/java -XX:+PrintFlagsFinal 2>/dev/null | grep String
bool OptimizeStringConcat = true {C2 product}
intx PerfMaxStringConstLength = 1024 {product}
bool PrintStringTableStatistics = false {product}
uintx StringTableSize = 60013 {product}
</code></pre>
<p>For OpenJDK 1.7:</p>
<pre><code>$ java -XX:+PrintFlagsFinal 2>/dev/null | grep String
bool OptimizeStringConcat = true {C2 product}
intx PerfMaxStringConstLength = 1024 {product}
bool PrintStringTableStatistics = false {product}
uintx StringTableSize = 60013 {product}
bool UseStringCache = false {product}
</code></pre>
<p>The <code>UseStringCache</code> option was removed in Java 8 with no replacement, so I doubt that makes any difference. The rest of the options appear to have the same settings.</p>
<p><strong>EDIT 3:</strong></p>
<p>A side-by-side comparison of the source code of the <code>AbstractStringBuilder</code>, <code>StringBuilder</code> and <code>Integer</code> classes from the <code>src.zip</code> file of reveals nothing noteworty. Apart from a whole lot of cosmetic and documentation changes, <code>Integer</code> now has some support for unsigned integers and <code>StringBuilder</code> has been slightly refactored to share more code with <code>StringBuffer</code>. None of these changes seem to affect the code paths used by <code>StringBuilder#append(int)</code>, although I may have missed something.</p>
<p>A comparison of the assembly code generated for <code>IntStr#integerToString()</code> and <code>IntStr#stringBuilder0()</code> is far more interesting. The basic layout of the code generated for <code>IntStr#integerToString()</code> was similar for both JVMs, although Oracle JDK 8u5 seemed to be more aggressive w.r.t. inlining some calls within the <code>Integer#toString(int)</code> code. There was a clear correspondence with the Java source code, even for someone with minimal assembly experience.</p>
<p>The assembly code for <code>IntStr#stringBuilder0()</code>, however, was radically different. The code generated by Oracle JDK 8u5 was once again directly related to the Java source code - I could easily recognise the same layout. On the contrary, the code generated by OpenJDK 7 was almost unrecognisable to the untrained eye (like mine). The <code>new StringBuilder()</code> call was seemingly removed, as was the creation of the array in the <code>StringBuilder</code> constructor. Additionaly, the disassembler plugin was not able to provide as many references to the source code as it did in JDK 8.</p>
<p>I assume that this is either the result of a much more aggressive optimization pass in OpenJDK 7, or more probably the result of inserting hand-written low-level code for certain <code>StringBuilder</code> operations. I am unsure why this optimization does not happen in my JVM 8 implementation or why the same optimizations were not implemented for <code>Integer#toString(int)</code> in JVM 7. I guess someone familiar with the related parts of the JRE source code would have to answer these questions...</p>

Link to specific tab Bootstrap
|
<p>I'm developing a site with Django Framework and I'm trying to create a way for when a user access a link like <a href="http://www.example.com/site/#users_rating">http://www.example.com/site/#users_rating</a> it opens a specific tab in the page.</p>
<p>I tried the following code that I found on the Internet (I'm new in JavaScript/JQuery), it isn't working:</p>
<pre><code><script type="text/javascript">
$(function() {
// Javascript to enable link to tab
var url = document.location.toString();
if (url.match('#')) {
$('.nav-tabs a[href=#'+url.split('#')[1]+']').tab('show') ;
}
// Change hash for page-reload
$('a[data-toggle="tab"]').on('show.bs.tab', function (e) {
window.location.hash = e.target.hash;
});
});
</script>
</code></pre>
<p>My template uses BootStrap 3, here is the HTML code (with some Django tags):</p>
<pre><code><div class="col-md-12" style="margin: 0 auto;">
<section class="panel">
<header class="panel-heading tab-bg-dark-navy-blue">
<ul class="nav nav-tabs nav-justified ">

</li>
<li class="">

</a>
</li>
<li class="">

Setting Global Variables in VBA
|
<p>I'm currently making an "OS" in PowerPoint and I need to know how to set global variables for the settings.</p>
<p>I made a module called "Settings" containing:</p>
<pre><code>Public Sub Settings()
Option Explicit
Public UserName, UserIcon, Background, BrowserHomePage As String
Public SetupComplete As Boolean
SetupComplete = False
UserName = "Administrator"
UserIcon = Nothing
Background = Nothing
BrowserHomePage = Nothing
'Set the variables
UserName.Text = UserName
End Sub
</code></pre>
<p>Now on the "log in" screen, I have a text box named "UserName". I then made a button just to test out the variables. The button does this:</p>
<pre><code>Private Sub CommandButton1_Click()
UserName.Value = UserName
End Sub
</code></pre>
<p>The text box has no value when I click the button. I'm super new at VBA, and would like to know how to do this. Also, if anyone knows how to automatically execute codes when starting the PowerPoint, that would be fantastic.</p>
<p>EDIT: I'm trying to make a module containing only the settings. Can someone point out how to change the values from slides? Like if I click a button in slide 1, I want it to change the "UserName" value in module "Settings" to whatever I want.</p>
<p><strong>Solution</strong>: Okay, I found the one solution. I have to write the settings to a text file and retrieve it for reading.</p>
<p>My settings module:</p>
<pre><code>Public UserName As String, Password As String, UserIcon As String, DesktopBackground As String, LogInBackground As String, BrowserHomePage As String
Public InitialSetupCompleted As Boolean
Public Sub ReadSettings()
'Delcaring variables
TempDir = Environ("Temp")
SettingsFileName = "\OpenOSSettings.txt"
SettingsFile = TempDir & SettingsFileName
ReadFile = FreeFile()
'Read all settings from file
Open SettingsFile For Input As #ReadFile
Do While Not EOF(ReadFile)
Line Input #ReadFile, Read
If Read Like "UserName = *" Then
UserName = Replace(Read, "UserName = ", "")
End If
If Read Like "Password = *" Then
Password = Replace(Read, "Password = ", "")
End If
If Read Like "UserIcon = *" Then
UserIcon = Replace(Read, "UserIcon = ", "")
End If
If Read Like "DesktopBackground = *" Then
DesktopBackground = Replace(Read, "DesktopBackground = ", "")
End If
If Read Like "LogInBackground = *" Then
LogInBackground = Replace(Read, "LogInBackground = ", "")
End If
If Read Like "BrowserHomePage = *" Then
BrowserHomePage = Replace(Read, "BrowserHomePage = ", "")
End If
If Read Like "InitialSetupCompleted = *" Then
InitialSetupCompleted = Replace(Read, "InitialSetupCompleted = ", "")
End If
Loop
Close #ReadFile
'Applying settings to all elements
Slide5.UserName.Caption = UserName
End Sub
Public Sub SaveSettings()
'Declaring variables
TempDir = Environ("Temp")
SettingsFileName = "\OpenOSSettings.txt"
SettingsFile = TempDir & SettingsFileName
WriteFile = FreeFile()
'Write all settings to file
Open SettingsFile For Output As #WriteFile
Print #WriteFile, "UserName = " & UserName
Print #WriteFile, "Password = " & Password
Print #WriteFile, "UserIcon = " & UserIcon
Print #WriteFile, "DesktopBackground = " & DesktopBackground
Print #WriteFile, "LogInBackground = " & LogInBackground
Print #WriteFile, "BrowserHomePage = " & BrowserHomePage
Print #WriteFile, "InitialSetupCompleted = " & InitialSetupCompleted
Close #WriteFile
End Sub
</code></pre>
<p>Now to save the settings, I just use a textbox and a button.
Saving the value of TextBox1 to UserName in the file:</p>
<pre><code>Private Sub CommandButton1_Click()
UserName = TextBox1.Value
Settings.SaveSettings
End Sub
</code></pre>
<p>Reading the value of UserName and put it into TextBox1:</p>
<pre><code>Private Sub CommandButton2_Click()
Settings.ReadSettings
TextBox2.Value = UserName
End Sub
</code></pre>
<p>Very long code, but it works well. Thanks everyone!</p>

Running Jupyter Notebook from cmd raises ModuleNotFoundError: No module named pysqlite2

<p><strong>The problem:</strong></p>
<p>After reinstalling <a href="https://www.anaconda.com/download/#windows" rel="noreferrer">Anaconda</a> I can no longer navigate to a folder using the command window where I've got some <code>.pynb</code> files, type <code>jupyter notebook</code> and get things up and running. I'm getting these errors:</p>

<hr>
<p><strong>What I've tried:</strong></p>
<hr>
<p>I've checked the fresh Anaconda folders, and everything seems to be where it should wrt <code>sqlite</code>, <code>sqlite3</code> and <code>pysqlite2</code>.</p>
<p>Since last time I downloaded Anaconda, it seems they've changed the default install folders, so I was sure everything would be OK after editing my user and system environment variables according to the post <a href="https://stackoverflow.com/questions/47318033/jupyter-notebook-will-not-open-from-command-prompt">Jupyter notebook will not open from command prompt</a> just in case checking the <code>Add to Path</code> option upon reinstalling Anaconda was not enough. But I'm still getting the same error messages.</p>
<p>When I launch Jupyter from the Anaconda Navigator, everything runs fine. </p>
<p>A similar question has been asked, but not answered, for Ubuntu here: <a href="https://stackoverflow.com/questions/47771364/2x-modulenotfounderror-jupyter-notebook">2x ModuleNotFoundError Jupyter notebook</a></p>
<hr>
<p><strong>Edit:</strong></p>
<hr>
<p>When I use and Anaconda Prompt, jupyter also starts running just fine when entering <code>jupyter notebook</code>. So why bother with the command window? The anaconda prompt command does not open ipynb files automatically in the deafault web browser. My earlier setup with the windows command window (and a batch file) did that and I think it was very useful.</p>

Put javascript on page from code behind
|
<p>I have some other javascript functions that are being set on the onfocus and onblur events of the textbox that I am using. In these functions it calls a generic javascript function that is not related to any controls. I want to know how to just simply spit this function out to the html of the page from the code behind. Something like this...</p>
<pre><code>Page.ClientScript.RegisterStartupScript(this.GetType(), "?????", getCounter);
</code></pre>
<p>EDIT: Here is what I mean</p>
<pre><code>public class MVADTextBox : TextBox
{
protected override void OnLoad(EventArgs e)
{
var getCounter = "<script language=\"javascript\">" +
"function GetCounter(input) {" +
//this function gets the number of special characters taht are in a row.
//it is only the grouping of characters that are right after your current position
"var textbox = document.getElementById(input.id);" +
"var mask = textbox.getAttribute('Mask');" +
"var inputCharacters = textbox.getAttribute('InputCharacters');" +
"var tbid = \"#\" + input.id;" +
"var position = $(tbid).caret().start;" +
"var counter = 0;" +
"for (var i = position; i < mask.length; i++) {" +
" if (mask[i] != '#') {" +
" counter++;" +
" if (mask[i + 1] == '#') {" +
" break;" +
" }" +
" }" +
"}" +
"return counter;" +
" }" +
"</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "OnFocus", onFocus);
Page.ClientScript.RegisterStartupScript(this.GetType(), "GetCounter(input)", getCounter);
var onBlur = "<script language=\"javascript\"> function PopulateField(input) {if (input.value == \"\") {input.value = input.defaultValue; input.className = 'sampleText'; } } </script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "OnFocus", onFocus);
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "OnBlur", onBlur);

<p>The on blur method is getting sent to the page.</p>

Cannot create JDBC driver of class '' for connect URL 'null' : Tomcat & SQL Server JDBC driver

<p>I've tried just about everything I can find out there, if someone is able to help me out, I will be eternally grateful (and a lot more free in my time).</p>

<p>The Context tab does have a closing tab, eventually.</p>
<p>Please help! If you need any more information, please let me know. Also, I'm not sure which context.xml ought to be modified, there are 2 in the Tomcat directories, one in the /conf folder, and one in the webapps/appname/META-INF folder. Sorry if it sounds like I'm a bit of a rookie, that's because I am!</p>
<p>Also, I've seen many different examples of the url="..." part of the context.xml, some including port numbers. I have tried several things out online, but nothing seems to work (doesn't help nothing online is my exact data environment, also I suppose it's challenging that this app queries two different DBs at given times).</p>
<p>Thoughts?</p>

</code></pre>
<p>So this works in most of the cases, but sometimes I get the following error:</p>
<pre><code>unprocessed continuation reference(s); remaining name "/"
</code></pre>
<p>I've searched a lot about this, and I explicitly set</p>
<pre><code>DefaultSpringSecurityContextSource ctxSrc = new DefaultSpringSecurityContextSource(ldapUrl);
ctxSrc.setReferral("follow");
</code></pre>
<p>Some more info:</p>
<ul>
<li>Search-query "admin_a" works, but "admin_ah" does not</li>
<li>Spring version is 4.2.5.RELEASE</li>
<li>Spring ldap-core version is 2.0.2.RELEASE</li>
</ul>
<p>I think it strange that the remaining name is the root directory... Does someone has any ideas how to fix this, or even where to start looking?</p>
<p>Thanks in advance!</p>

PrimeNG Form Validation

<p>I am using a mix of primeNG controls and html controls. The issue is the primeNG controls don't work properly for the phone mask and for he auto-complete the style is different .</p>
<p>for example:
<strong>html</strong> (phone is never showing as red if the user set focus on the control then just tab to the next control)</p>
<pre><code> <div class="form-group col-xs-3 col-md-3"

'has-error':(ersaForm.get('phone').touched || ersaForm.get('phone').dirty ) &&

}">
<label for="phoneId" class="control-label">Phone</label><br />
<!--<input type="tel" class="form-control" id="phone" placeholder="Phone">-->
<p-inputMask mask="(999) 999-9999" formControlName="phone" id="nameId" required placeholder="Phone (required)"></p-inputMask>
<span class="help-block" *ngIf="(ersaForm.get('phone').touched || ersaForm.get('phone').dirty ) &&

<p>I would like that the title in the menu will change by the fragment name that was click. for the code below what i get is that, the actual title in each fragment is "Home" and its does not change. but i found that when i click on an item in the menu the title changing for a second and return back to the "Home" title. i implemented the ondrawer but still i don't know what could cause that.</p>

Glide : How to find if the image is already cached and use the cached version?
|
<p><strong>Scenario</strong>: </p>
<p>I have a large GIF image which I want to cache the first time user opens the app using <a href="https://github.com/bumptech/glide" rel="noreferrer">Glide</a> - Image Loading and Caching library. After that whenever user opens the app, I want to show the cached version if present. This GIF URL will expire after a given interval. When it expires, I fetch the new GIF URL and display/cache that for future use.</p>
<p><strong>What I tried:</strong></p>
<p>I went through <a href="https://github.com/bumptech/glide/wiki/Caching-and-Cache-Invalidation" rel="noreferrer">Caching and Cache Invalidation</a> on Glide's github page. I also went though the Google Group thread <a href="https://groups.google.com/forum/#!topic/glidelibrary/TcFOy0tcxXA" rel="noreferrer">Ensuring That Images Loaded Only Come From Disk Cache</a>, which shows how to get the image form cache. I also went through <a href="https://stackoverflow.com/questions/31537669/how-to-invalidate-glide-cache-for-some-specific-images">How to invalidate Glide cache for some specific images</a> question.</p>
<p>From the links above I see the following code sniplet which shows how to load the image from cache. However this only tries to get the image from cache. If its not present in cache, it doesn't try to get from the network and fails:</p>
<pre><code>Glide.with(TheActivity.this)
.using(new StreamModelLoader<String>() {
@Override
public DataFetcher<InputStream> getResourceFetcher(final String model, int i, int i1) {
return new DataFetcher<InputStream>() {
@Override
public InputStream loadData(Priority priority) throws Exception {
throw new IOException();
}
@Override
public void cleanup() {
}
@Override
public String getId() {
return model;
}
@Override
public void cancel() {
}
};
}
})
.load("http://sampleurl.com/sample.gif")
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(theImageView);
</code></pre>
<p><strong>Questions:</strong></p>
<ol>
<li><p>Is there a cleaner way to achieve the following: Show the GIF image from the cache if present else download the GIF, cache it for later use and show it in the <code>ImageView</code>.</p></li>
<li><p>The caching article above mentions the following: </p>
<blockquote>
<p>In practice, the best way to invalidate a cache file is to change
your identifier when the content changes (url, uri, file path etc)</p>
</blockquote>
<p>The server sends a different URL to the app when the previous one expires. In this case, I believe the old image will eventually be Garbage Collected? Is there a way to force remove the image from the cache?</p></li>
<li><p>On a similar note, is there a way to prevent the Garbage Collection of an image with specific key (to prevent downloading the large file again) and then later instruct to delete the old image from cache when the URL changes?</p></li>
</ol>

Symfony2 UniqueConstraint and UniqueEntity (Integrity Violation)
|
<p>I've got a little problem with a Doctrine entity for a few days now. I've defined it with a UniqueConstraint on two fields with a UniqueEntity Validation on these two fields after that. But after validating of my form with a adding of an entity already in base, no way to obtain my error message in my form.</p>
<p>Just an error message from Symfony : </p>
<blockquote>
<p>SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '339057986-00012' for key 'SIRET'</p>

Problems with createImage(int width, int height)
|
<p>I have the following code, which is run every 10ms as part of a game:</p>
<pre><code>private void gameRender()
{
if(dbImage == null)
{
//createImage() returns null if GraphicsEnvironment.isHeadless()
//returns true. (java.awt.GraphicsEnvironment)
dbImage = createImage(PWIDTH, PHEIGHT);
if(dbImage == null)
{
System.out.println("dbImage is null"); //Error recieved
return;
}
else
dbg = dbImage.getGraphics();
}
//clear the background
dbg.setColor(Color.white);
dbg.fillRect(0, 0, PWIDTH, PHEIGHT);
//draw game elements...
if(gameOver)
{
gameOverMessage(dbg);
}
}
</code></pre>
<p>The problem is that it enters the if statement which checks for the Image being null, even after I attempt to define the image. I looked around, and it seems that createImage() will return null if GraphicsEnvironment.isHeadless() returns true.</p>
<p>I don't understand exactly what the isHeadless() method's purpose is, but I thought it might have something to do with the compiler or IDE, so I tried on two, both of which get the same error (Eclipse, and BlueJ). Anyone have any idea what the source of the error is, and how I might fix it?</p>
<p>Thanks in advance</p>
<p>Jonathan</p>
<p>...................................................................</p>
<p>EDIT:
I am using java.awt.Component.createImage(int width, int height). The purpose of this method is to ensure the creation of, and edit an Image that will contain the view of the player of the game, that will later be drawn to the screen by means of a JPanel.
Here is some more code if this helps at all:</p>

{

requestFocus(); //Sim2D now recieves key events
readyForTermination();
addMouseListener( new MouseAdapter() {

{ testPress(e.getX(), e.getY()); }
});
} //end of constructor

}
}
});

beforeTime = System.nanoTime();

paintScreen(); //paints rendered image to screen
timeDiff = (System.nanoTime() - beforeTime) / 1000000;
sleepTime = 10 - timeDiff;
if(sleepTime <= 0) //if took longer than 10ms
{

}

How to enable code hinting using codemirror?

<p>I am using codemirror to allow the user to type anycode like css/html/js.</p>
<p>I need to enable if the user type something like in css mode</p>
<pre><code>div {
padding-

<pre><code>div {
padding-top
padding-left
padding-right
padding-bottom
}

JAXB not available on Tomcat 9 and Java 9/10
|
<p><strong>TLDR</strong>: On Java 9/10, a web app in Tomcat has no access to JAXB even though its reference implementation is present on the class path.</p>
<p><strong>Edit</strong>: No, this is not a duplicate of <a href="https://stackoverflow.com/q/43574426/2525313">How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException in Java 9</a> - as you can tell by the <em>What I tried</em> section, I already tried the proposed solutions.</p>
<h1>The Situation</h1>
<p>We have a web app that runs on Tomcat and depends on JAXB. During our migration to Java 9 we opted for adding <a href="https://stackoverflow.com/a/48204154/2525313">the JAXB reference implementation as a regular dependency</a>.</p>
<p>Everything worked when launching the app from the IDE <a href="https://tomcat.apache.org/tomcat-9.0-doc/api/org/apache/catalina/startup/Tomcat.html" rel="noreferrer">with embedded Tomcat</a>, but when running it on a real Tomcat instance, I get this error:</p>
<pre><code>Caused by: java.lang.RuntimeException: javax.xml.bind.JAXBException:

<p>That's clearly the same class, so apparently it has been loaded by two class loaders. I suspect <a href="https://tomcat.apache.org/tomcat-9.0-doc/class-loader-howto.html#Class_Loader_Definitions" rel="noreferrer">the system class loader and the app's class loader</a>, but why would loading <code>JAXBContext</code> be delegated to the system class loader once but not always? It almost looks as if the delegation behavior of the app's class loader changes while the program runs.</p>
<h2>Adding the module</h2>
<p>I don't really want to add <em>java.xml.bind</em>, but I tried it anyways by adding this to <code>catalina.sh</code>:</p>
<pre><code>JDK_JAVA_OPTIONS="$JDK_JAVA_OPTIONS --add-modules=java.xml.bind"
</code></pre>
<p>Doesn't work either, though:</p>
<pre><code>Caused by: java.lang.ClassCastException:
java.xml.bind/com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl
cannot be cast to com.sun.xml.bind.v2.runtime.JAXBContextImpl
at [... our-code ...]
</code></pre>
<p>Apart from the different class and stack trace, this is in line with what happened earlier: The class <code>JAXBContextImpl</code> was loaded twice, once from <em>java.xml.bind</em> (must have been the system class loader) and one other time (I assume by the app's loader from the JAR).</p>
<h2>Searching for bugs</h2>
<p><a href="https://bz.apache.org/bugzilla/query.cgi" rel="noreferrer">Searching Tomcat's bug database</a> I found <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=62559" rel="noreferrer">#62559</a>. Could that be the same error?</p>
<h2>Adding JAR's to Tomcat's <code>lib</code></h2>
<p>Following <a href="http://mail-archives.apache.org/mod_mbox/tomcat-users/201807.mbox/%3cb1ca948e-f8d3-5c5e-9aaf-0c8c6c9f84d0@christopherschultz.net%3e" rel="noreferrer">advice given on the Tomcat user mailing list</a>, I added the JAXB JARs to Tomcat's <code>CATALINA_BASE/lib</code> directory, but got the same error as in the application's lib folder.</p>

Eject USB device via C#

<p>I was looking for a short way to eject USB-devices via C#-code, so I coded a little class myself, yet it simply doesn't work. Since there's no popup that says "Lock success!" I assume that the problem relies within the "LockVolume"-function, but I don't know where.</p>

Record Audio on Website that works on all browsers and iOS
|
<p>I have wasted a ton of time implementing multiple audio recording options in a website I'm building but each one either only works in Chrome, only in Firefox, both but not Safari, and none work on iOS. </p>
<p>The website needs to allows the user to record their message and save it in a form state for submission. </p>
<p>All the current articles I am reading are a few months old and mention that iOS doesn't/will support it soon. I've tried mobile Chrome on iOS and it still didn't work. </p>
<p>Has anyone found a way to simply record audio in a browser as well as mobile website??</p>
<p>Things I've tried:</p>
<ul>
<li>Francium Voice (An abandoned javascript project, works for Chrome. Records and saves and I am able to send the audio file through the form data. <a href="https://subinsb.com/html5-record-mic-voice/" rel="noreferrer">https://subinsb.com/html5-record-mic-voice/</a>. But this uses the < audio > tag which shows as "error" and doesn't allow you to record. </li>
<li>I started trying getUserMedia() as that seems to be the new standard and says it's supported on more devices/browsers but the mic wouldn't work on iOS either. <a href="https://www.html5rocks.com/en/tutorials/getusermedia/intro/" rel="noreferrer">https://www.html5rocks.com/en/tutorials/getusermedia/intro/</a></li>
<li>Many articles say to use the Record.js, <a href="https://github.com/mattdiamond/Recorderjs" rel="noreferrer">https://github.com/mattdiamond/Recorderjs</a>, but that is also an abandoned project. I could only get the audio to record, but it wasn't saving it. Again not working in Safari or iOS. </li>
<li>I tried using the audio/* technique but couldn't get it to work right. It would only show an upload button, couldn't get the mic option to show. Based on the documentation it seems like the one that "should" work though. <a href="https://developers.google.com/web/fundamentals/media/recording-audio/" rel="noreferrer">https://developers.google.com/web/fundamentals/media/recording-audio/</a></li>
</ul>
<p>Currently using the following code which works, for Chrome and Firefox.</p>
<p>HTML</p>
<p><code><audio controls src="" id="audio"></audio>
<a class="button" id="record">Record</a>
<input type="hidden" id="audiofile" name="audiofile" value="" aria-hidden="true"/></code></p>
<p>Using the Francium Voice library:</p>
<p>Javascript</p>
<pre><code> // Audio Recording for Phone Calls
$(document).on("click", "#record:not(.stop)", function(){
elem = $(this);
$("#audio").attr("src","");
$("#audiofile").val("");
Fr.voice.record($("#live").is(":checked"), function(){
elem.addClass("stop");
});
elem.html("Stop <label id='minutes'>00</label>:<label id='seconds'>00</label>");
var minutesLabel = document.getElementById("minutes");
var secondsLabel = document.getElementById("seconds");
var totalSeconds = 0;
setInterval(setTime, 1000);
function setTime() {
++totalSeconds;
secondsLabel.innerHTML = pad(totalSeconds % 60);
minutesLabel.innerHTML = pad(parseInt(totalSeconds / 60));
}
function pad(val) {
var valString = val + "";
if (valString.length < 2) {
return "0" + valString;
} else {
return valString;
}
}
});
$(document).on("click", ".stop", function(){
elem = $(this);
elem.html("Record");
elem.removeClass("stop");
Fr.voice.export(function(base64){
$("#audio").attr("src", base64);
$("#audiofile").val(base64);
$("#audio")[0].play();
}, "base64");
Fr.voice.stop();
});

JavaFx USE_COMPUTED_SIZE for Stage without using FXML
|
<p>In the JavaFX Scene Builder, I can select a value for the minimum, maximum and preferred width and height of a <code>Control</code> or <code>Container</code>. There are predefined values like <code>USE_COMPUTED_SIZE</code>.</p>
<p>I came to the conclusion, that I don't like to use FXML for my current project, for several reasons and now I am wondering how to set those values when not using FXML.</p>
<p>How do I do this?</p>
<p>I've tried the following code:</p>
<pre><code>initializeControls();
addControls();
setMinHeight(Control.USE_COMPUTED_SIZE);
setMinWidth(Control.USE_COMPUTED_SIZE);
addActionListeners();
addFocusChangeListeners();
</code></pre>
<p>However, that results in an Exception when trying to create the Stage:</p>
<pre><code>Exception in thread "JavaFX Application Thread" java.lang.IllegalArgumentException: The width and height must be >= 0. Got: width=-1; height=-1

<p>I guess, that I took the <code>USE_COMPUTED_SIZE</code> value from the wrong class or something, but where do I get the correct value from? Or is this whole approach somehow wrong?</p>
<p>My ultimate goal is to make the stage take as much space as is needed to display all the controls and containers in it, but not more.</p>
<p>EDIT#1:
Correction: It should take as much space as needed as a <em>Minimum</em> width and height, so that the window is still resizeable but cannot be made so small that controls are not displayed any more.</p>
<p>EDIT#2:
Result of trying to set the minimum width + height on a smaller example app:

How to fix: Data path "" should have required property 'browserTarget' error in Angular 8 when running ng serve or npm start
|
<p>I'm trying to run either 'ng serve' or 'npm start' to run my angular 8 server on localhost:4200 in cmd on a windows machine. I get a Schema error I think I know where the problem is but no idea how to fix it.</p>
<p>Another point to note is this was working perfectly fine until windows restarted my computer to do an update.</p>
<p>I'm also running tailwind through a webpack.</p>
<p>The main part of the error is: Data path "" should have required property 'browserTarget'</p>
<pre><code>"serve": {
"builder": "@angular-builders/custom-webpack:dev-server",
"options": {
"customWebpackConfig": {
"path": "./webpack.config.js"
}
}
},
</code></pre>
<p>I assume I need to add browserTarget in the options here, when I do that I get an error saying I need main in there too.</p>
<p>Am I on the right track?
If I am, what are the values that should be attributed to these properties?</p>
<p>Any help would be greatly appreciated. </p>
<p>I've tried:</p>
<ul>
<li><p>Upgrading my packages.</p></li>
<li><p>Upgrading Angular</p></li>
<li><p>Deleting the node modules folder and npm installing</p></li>

Execute a string of PHP code on the command line
|
<p>I'd like to be able to run a line of PHP code on the command line similar to how the following options work:</p>
<pre><code>perl -e "print 'hi';"
python -c "print 'hi'"
ruby -e "puts 'hi'"
</code></pre>
<p>I'd like to be able to do:</p>
<pre><code>php "echo 'hi';"
</code></pre>
<p>I've read that there is a <code>-r</code> option that can do what I need for php, however it doesn't appear to be available when I try to use it. I've tried using PHP 5.2.13 and PHP 4.4.9 and neither have an <code>-r</code> option available.</p>
<p>I wrote this script (that I called run_php.php) - which works, but I'm not a huge fan of it just because I feel like there should be a more "correct" way to do it.</p>
<pre><code>#!/usr/bin/php5 -q
<?php echo eval($argv[1]); ?>
</code></pre>
<p>Is there a <code>-r</code> option? If so, why is it not available when I run <code>--help</code>? If there is no <code>-r</code> option, what is the best way to do this (without writing an intermediary script if possible)?</p>
<hr/>
<p>Because I don't think it was very clear above, the <code>-r</code> option is <em>not</em> available to me. Here is the <code>php -h</code> output for both versions of PHP that I'm running.</p>
<p>PHP 4.4.9</p>
<pre class="lang-none prettyprint-override"><code>Usage: php [-q] [-h] [-s] [-v] [-i] [-f <file>]

How to return Observable inside a subscription
|
<p>I want to call http request inside a observable which makes select operation from database. I made two services, <strong>DbService</strong> and <strong>BackendService</strong>. </p>
<p>BackendService makes http post requests and returns response data. In my design BackendService should subscribe to DbService for getting url, after that make http post request then return response data. </p>
<p>BackendService can take url from DbService and try to make http request but couldn't. response data is (Json format)</p>
<pre><code>{"_isScalar":false,"source":{"_isScalar":false},"operator":{}}

Angular JS table with ng-repeat and radio buttons
|
<p>I am trying to make a table using ng-repeat that has a radio button selector at the start of each row. The table looks like this:</p>
<pre><code><table>
<tbody>
<tr ng-repeat="model in modelList">
<td>
<input type="radio" ng-model="model.select"></input>
</td>
<td>{{ model.NDPName }}</td>
<td>{{ model.OEM }}</td>
<td>{{ model.version }}</td>
<td>{{ model.dateAdded }}</td>
<td>{{ model.validUntil }}</td>
</tr>
</tbody>
</table>
</code></pre>
<p>The ng-repeat is taking from a modelList that looks like:</p>
<pre><code> $scope.modelList =
[
{
select: false,
NDPName: "NDP1",
OEM: "CHOAM Inc.",
version: "01",
dateAdded: "Jan 1, 2013",
validUntil: "Jan 1, 2014",
},
{
select: false,
NDPName: "NDP2",
OEM: "Tyrell Corp.",
version: "01",
dateAdded: "Jan 1, 2014",
validUntil: "Jan 1, 2015",
},
{
select: false,
NDPName: "NDP3",
OEM: "Stark Industries",
version: "01",
dateAdded: "Jan 1, 2015",
validUntil: "Jan 1, 2016",
},
{
select: false,
NDPName: "NDP4",
OEM: "Monsters Inc.",
version: "01",
dateAdded: "Jan 1, 2016",
validUntil: "Jan 1, 2017",
},
{
select: false,
NDPName: "NDP5",
OEM: "ACME Corp",
version: "01",
dateAdded: "Jan 1, 2017",
validUntil: "Jan 1, 2018",
}
];
</code></pre>
<p>The problem I am running into is that the radio buttons are not behaving like radio buttons. They are each in a separate scope and will therefore allow multiple rows in the table to be selected. How can I fix this?</p>

Spark and Java: Exception thrown in awaitResult
|
<p>I am trying to connect a Spark cluster running within a virtual machine with IP <code>10.20.30.50</code> and port <code>7077</code> from within a Java application and run the word count example:</p>
<pre><code>SparkConf conf = new SparkConf().setMaster("spark://10.20.30.50:7077").setAppName("wordCount");
JavaSparkContext sc = new JavaSparkContext(conf);
JavaRDD<String> textFile = sc.textFile("hdfs://localhost:8020/README.md");
String result = Long.toString(textFile.count());
JavaRDD<String> words = textFile.flatMap((FlatMapFunction<String, String>) s -> Arrays.asList(s.split(" ")).iterator());
JavaPairRDD<String, Integer> pairs = words.mapToPair((PairFunction<String, String, Integer>) s -> new Tuple2<>(s, 1));
JavaPairRDD<String, Integer> counts = pairs.reduceByKey((Function2<Integer, Integer, Integer>) (a, b) -> a + b);
counts.saveAsTextFile("hdfs://localhost:8020/tmp/output");
sc.stop();
return result;
</code></pre>
<p>The Java application shows the following stack trace:</p>

Remove node from TreeView
|
<p>I want to create this simple example of javaFX TreeView with context menu which can remove nodes from the tree:</p>
<pre><code>public class TreeViewSample extends Application {
private final Node rootIcon = new ImageView(
new Image(getClass().getResourceAsStream("folder_16.png"))
);
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Tree View Sample");
TreeItem<String> rootItem = new TreeItem<String> ("Inbox", rootIcon);
rootItem.setExpanded(true);
for (int i = 1; i < 6; i++) {
TreeItem<String> item = new TreeItem<String> ("Message" + i);
rootItem.getChildren().add(item);
}
TreeView<String> tree = new TreeView<String> (rootItem);
StackPane root = new StackPane();
root.getChildren().add(tree);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
</code></pre>
<p>I tested this context menu to remove right click selected node:</p>
<pre><code>final ContextMenu contextMenu = new ContextMenu();
MenuItem item1 = new MenuItem("About");
item1.setOnAction(new EventHandler<ActionEvent>()
{
@Override
public void handle(ActionEvent e)
{
System.out.println("About");
}
});
MenuItem item2 = new MenuItem("Preferences");
item2.setOnAction(new EventHandler<ActionEvent>()
{
@Override
public void handle(ActionEvent e)
{
System.out.println("Preferences");
}
});
MenuItem item3 = new MenuItem("Remove");
item3.setOnAction(new EventHandler<ActionEvent>()
{
@Override
public void handle(ActionEvent e)
{
DynamicTreeNodeModel c = treeView.getSelectionModel().getSelectedItem().getValue();
boolean remove = treeView.getSelectionModel().getSelectedItem().getChildren().remove(c);
System.out.println("Remove");
}
});
contextMenu.getItems().addAll(item1, item2, item3);
treeView.setContextMenu(contextMenu);
</code></pre>
<p>For some reason the code is not working. Can you help me to fix this issue?</p>

Shared x and y axis labels ggplot2 with ggarrange
|
<p>I have a number off ggplot objects created based off dichotomous count data. I have combined them together using ggarrange. In this function, there is an option to create a shared legend, but as far as I can see no way to create shared x and y axis labels. In addition, the spacing of the figures is very weird - there is a huge gap between the two figure columns, and in addition a large amount of vertical space before the shared legend. So in sum I would like to be able to create shared x and y axes and minimise the unnecessary vertical and horizontal space.</p>
<p>I checked out the following threads:
<a href="https://stackoverflow.com/questions/46201091/ggplot2-grid-arrange-shared-legend-share-axis-labels">ggplot2 grid_arrange_shared_legend share axis labels</a></p>
<p><a href="https://stackoverflow.com/questions/39011020/ggplot-align-plots-together-and-add-common-labels-and-legend">ggplot: align plots together and add common labels and legend</a></p>
<p><a href="https://stackoverflow.com/questions/57812266/add-common-axis-titles-with-lines-arrows-for-multiple-plots-in-ggplot">Add common axis titles with lines/arrows for multiple plots in ggplot</a></p>
<p><a href="https://stackoverflow.com/questions/39008773/ggplot-how-to-add-common-x-and-y-labels-to-a-grid-of-plots">ggplot: how to add common x and y labels to a grid of plots</a></p>
<p>But I think what I want to do is quite a bit simpler, and I don't know how to combine ggarrange with facet.grid which was suggested a few times.</p>
<p>I have copied a reproducible example below.</p>

How to define max_queue_size, workers and use_multiprocessing in keras fit_generator()?
|
<p>I am applying transfer-learning on a pre-trained network using the GPU version of keras. I don't understand how to define the parameters <strong><code>max_queue_size</code></strong>, <strong><code>workers</code></strong>, and <strong><code>use_multiprocessing</code></strong>. If I change these parameters (primarily to speed-up learning), I am unsure whether all data is still seen per epoch.</p>
<p><strong><code>max_queue_size</code></strong>:</p>
<ul>
<li><p>maximum size of the internal training queue which is used to "precache" samples from the generator </p></li>
<li><p><em>Question:</em> Does this refer to how many batches are prepared on CPU? How is it related to <code>workers</code>? How to define it optimally?</p></li>
</ul>
<p><strong><code>workers</code></strong>: </p>
<ul>
<li><p>number of threads generating batches in parallel. Batches are computed in parallel on the CPU and passed on the fly onto the GPU for neural network computations </p></li>
<li><p><em>Question:</em> How do I find out how many batches my CPU can/should generate in parallel?</p></li>
</ul>
<p><strong><code>use_multiprocessing</code></strong>: </p>
<ul>
<li><p>whether to use process-based threading</p></li>
<li><p><em>Question:</em> Do I have to set this parameter to true if I change <code>workers</code>? Does it relate to CPU usage?</p></li>
</ul>

class_weight=classWeights, # optional dictionary mapping class indices (integers) to a weight (float) value, used for weighting the loss function
max_queue_size=10, # maximum size for the generator queue
workers=1, # maximum number of processes to spin up when using process-based threading

In ReactJS, why does `setState` behave differently when called synchronously?
|
<p>I am trying to understand the underlying cause for some somewhat "magical" behavior I am seeing that I cannot fully explain, and which is not apparent from reading the ReactJS source code.</p>
<p>When calling the <code>setState</code> method synchronously in response to an <code>onChange</code> event on an input, everything works as expected. The "new" value of the input is already present, and so the DOM is not actually updated. This is highly desirable because it means the cursor will not jump to the end of the input box.</p>
<p>However, when running a component with exactly the same structure but that calls <code>setState</code> <em>asynchronously</em>, the "new" value of the input does not appear to be present, causing ReactJS to actually touch the DOM, which causes the cursor to jump to the end of the input.</p>
<p>Apparently, something is intervening to "reset" the input back to its prior <code>value</code> in the asynchronous case, which it is not doing in the synchronous case. What is this mechanic?</p>
<p><strong>Synchronous Example</strong></p>
<pre class="lang-js prettyprint-override"><code>var synchronouslyUpdatingComponent =
React.createFactory(React.createClass({
getInitialState: function () {
return {value: "Hello"};
},
changeHandler: function (e) {
this.setState({value: e.target.value});
},
render: function () {
var valueToSet = this.state.value;
console.log("Rendering...");
console.log("Setting value:" + valueToSet);
if(this.isMounted()) {
console.log("Current value:" + this.getDOMNode().value);
}
return React.DOM.input({value: valueToSet,
onChange: this.changeHandler});
}
}));
</code></pre>
<p>Note that the code will log in the <code>render</code> method, printing out the current <code>value</code> of the actual DOM node.</p>
<p>When typing an "X" between the two Ls of "Hello", we see the following console output, and the cursor stays where expected:</p>
<pre class="lang-none prettyprint-override"><code>Rendering...
Setting value:HelXlo
Current value:HelXlo
</code></pre>
<p><strong>Asynchronous Example</strong></p>
<pre class="lang-js prettyprint-override"><code>var asynchronouslyUpdatingComponent =
React.createFactory(React.createClass({
getInitialState: function () {
return {value: "Hello"};
},
changeHandler: function (e) {
var component = this;
var value = e.target.value;
window.setTimeout(function() {
component.setState({value: value});
});
},
render: function () {
var valueToSet = this.state.value;
console.log("Rendering...");
console.log("Setting value:" + valueToSet);
if(this.isMounted()) {
console.log("Current value:" + this.getDOMNode().value);
}
return React.DOM.input({value: valueToSet,
onChange: this.changeHandler});
}
}));
</code></pre>
<p>This is precisely the same as the above, except that the call to <code>setState</code> is in a <code>setTimeout</code> callback.</p>
<p>In this case, typing an X between the two Ls yields the following console output, and the cursor jumps to the end of the input:</p>
<pre class="lang-none prettyprint-override"><code>Rendering...
Setting value:HelXlo
Current value:Hello
</code></pre>
<hr>
<p><strong>Why is this?</strong></p>
<p>I understand React's concept of a <a href="http://facebook.github.io/react/docs/forms.html#controlled-components">Controlled Component</a>, and so it makes sense that user changes to the <code>value</code> are ignored. But it looks like the <code>value</code> is in fact changed, and then explicitly reset. </p>
<p>Apparently, calling <code>setState</code> synchronously ensures that it takes effect <em>before</em> the reset, while calling <code>setState</code> at any other time happens <em>after</em> the reset, forcing a re-render.</p>
<p>Is this in fact what's happening?</p>

Get footer row cell values of gridview

<p>I have a gridview with two textboxes in the footer. What's required is get the textbox values, store it to a datatable and then bind the same to the gridview.
I am unable to get the textbox values. They show up empty (as you can see). Where am I going wrong.</p>

Symfony - How to access entity's repository
|
<p>There are several ways that we can access the entity's repository in Symfony2 controllers or services which each has its advantage and disadvantage. First I list them here and then asking if there is any better solution or these are the only options that we have and we should choose one or some based on our preferences. I also want to know if method 5 (which I've started to use it recently) can be good and doesn't break any rule or having any side effects.</p>
<p><strong>Basic Method:</strong> Use entity manager in the controller or Inject it to a service and then accessing any repository that I want. This is the basic way of accessing a Repository in controller or service.</p>
<pre><code>class DummyController
{
public function dummyAction($id)
{
$em = $this->getDoctrine()->getManager();
$em->getRepository('ProductBundle:Product')->loadProduct($id);
}
}
</code></pre>
<p>But there are some problems related to this method. The first problem is that I cannot do Ctrl + click on for example loadProduct function and go directly to its implementation (Unless there is a way that I don't know). The other problem is that I will end up repeating this part of code over and over.</p>
<p><strong>Method 2:</strong> The other method is just to define a getter in my service or controller to access my repository.</p>
<pre><code>class DummyService
{
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
public function dummyFunction($id)
{
$this->getProductRepository()->loadProduct($id);
}
/**
* @return \ProductBundle\Entity\Repository\ProductRepository
*/
public function getProductRepository()
{
return $this->em->getRepository('ProductBundle:Product');
}
}
</code></pre>
<p>This method solves the first problem and somehow the second but still, I have
to repeat all getters that I need in my service or controller, also I will have several getters in my services and controllers just for accessing to repositories</p>
<p><strong>Method 3:</strong> Another way is to inject a repository to my service, it is nice especially if we have a good control on our code and we are not involved with other developers who inject the entire Container into your service.</p>
<pre><code>class DummyService
{
protected $productRepository;
public function __construct(ProductRepository $productRepository)
{
$this->productRepository = $productRepository;
}
public function dummyFunction($id)
{
$this->productRepository->loadProduct($id);
}
}
</code></pre>
<p>This method solves the first and second problem, but if my service is big
and it needs to deal with a lot of repositories then it is not a nice idea to
inject for example 10 repository to my service.</p>
<p><strong>Method 4:</strong> Another way is to have a service to wrap all of my repositories and inject this service to other services.</p>
<pre><code>class DummyService
{
protected $repositoryService;
public function __construct(RepositoryService $repositoryService)
{
$this->repositoryService = $repositoryService;
}
public function dummyFunction($id)
{
$this->repositoryService->getProductRepository()->loadProduct($id);
}
}
</code></pre>
<p>RepositoryService:</p>
<pre><code>class RepositoryService
{
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
/**
* @return \ProductBundle\Entity\Repository\ProductRepository
*/
public function getProductRepository()
{
return $this->em->getRepository('ProductBundle:Product');
}
/**
* @return \CmsBundle\Entity\Repository\PageRepository
*/
public function getPageRepository()
{
return $this->em->getRepository('CmsBundle:Page');
}
}
</code></pre>
<p>This method also solves the first and second problem. But RepositoryService can become so big when we have for example 200 entities.</p>
<p><strong>Method 5:</strong> Finally I can define a static method in each entity which returns its repository.</p>
<pre><code>class DummyService
{
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
public function dummyFunction($id)
{
Product::getRepository($this->em)->loadProduct($id);
}
}
</code></pre>
<p>My Entity:</p>
<pre><code>/**
* Product
*
* @ORM\Table(name="saman_product")
* @ORM\Entity(repositoryClass="ProductBundle\Entity\ProductRepository")
*/
class Product
{
/**
*
* @param \Doctrine\ORM\EntityManagerInterface $em
* @return \ProductBundle\Entity\ProductRepository
*/
public static function getRepository(EntityManagerInterface $em)
{
return $em->getRepository(__CLASS__);
}
}
</code></pre>
<p>This method solves the first and second problem also I do not need to define a
service to access repositories. I've used it recently and so far its the best method for me. I don’t think this method will break the rule of entities since it's defined in the class scope and also is so thine. But still I am not sure about it and whether or not it has any side effects.</p>

How to stop all the running threads, if one of those throws an Exception?
|
<p>In one of my application I'm using the <code>ExecutorService</code> class to create a fixed thread pool and <code>CountDownLatch</code> to wait for the threads to complete. This is working fine if the process didn't throw any exception . If there is an exception occurred in any of the threads, I need to stop all the running thread and report the error to the main thread. Can any one please help me to solve this? </p>
<p>This is the sample code I'm using for executing multiple threads.</p>
<pre><code> private void executeThreads()
{
int noOfThreads = 10;
ExecutorService executor = Executors.newFixedThreadPool(noOfThreads);
try
{
CountDownLatch latch = new CountDownLatch(noOfThreads);
for(int i=0; i< noOfThreads; i++){
executor.submit(new ThreadExecutor(latch));
}
latch.await();
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
executor.shutDown();
}
}
</code></pre>
<p>This is the Executor Class</p>
<pre><code> public class ThreadExecutor implements Callable<String> {
CountDownLatch latch ;
public ThreadExecutor(CountDownLatch latch){
this.latch = latch;
}
@Override
public String call() throws Exception
{
doMyTask(); // process logic goes here!
this.latch.countDown();
return "Success";
}
</code></pre>
<p>=============================================================================</p>
<p>Thank you all :)</p>
<p>I have corrected my class as given below and that is working now.</p>
<pre><code>private void executeThreads()
{
int noOfThreads = 10;
ExecutorService executor = Executors.newFixedThreadPool(noOfThreads);
ArrayList<Future<Object>> futureList = new ArrayList<Future<Object>>(noOfThreads );
try
{
userContext = BSF.getMyContext();
CountDownLatch latch = new CountDownLatch(noOfComponentsToImport);
for(ImportContent artifact:artifactList){
futureList.add(executor.submit(new ThreadExecutor(latch)));
}
latch.await();
for(Future<Object> future : futureList)
{
try
{
future.get();
}
catch(ExecutionException e)
{ //handle it
}
}
}
catch (Exception e) {
//handle it
}
finally
{
executor.shutdown();
try
{
executor.awaitTermination(90000, TimeUnit.MILLISECONDS);
}
catch (InterruptedException e)
{
//handle it
}
}
}
</code></pre>
<p>Executor Class :</p>

SASS/CSS: :first-child selector not working
|
<p>I'm trying to style a certain <code><div></code> in my markup with CSS/SASS, and I'm clueless as to why it's not applying the rules. This is my markup:</p>
<pre><code><div class="row addon-header">
<div class="col-sm-3">
// something here
</div>
<div class="col-sm-9">
<h2>Title</h2>
<h6><em>Slogan</em></h6>
<div class="col-xs-1">
// I want to access this
</div>
<div class="col-xs-1"></div>
<div class="col-xs-1"></div>
<div class="col-xs-1"></div>
</div>
</div>
</code></pre>
<p>And this is the SASS I'm trying to use for it:</p>
<pre><code>div.addon-header {
color: white;
> div.col-sm-9 > div.col-xs-1:first-child {
background-color: black;
padding-left: 0px !important;
}
}
</code></pre>
<p>If I remove the <code>:first-child</code> selector in my SASS, it's working, but obvious for every <code><div class="col-xs-1"></code> not just the first one, which is not what I want.</p>
<p>I also tried playing around and doing something like</p>
<pre><code>div.addon-header {
color: white;
> div.col-sm-9 > div.col-xs-1 {
&:first-child {
background-color: black;
padding-left: 0px !important;
}
}
}
</code></pre>
<p>or</p>
<pre><code>div.addon-header {
color: white;
> div.col-sm-9 {
> div.col-xs-1:first-child {
background-color: black;
padding-left: 0px !important;
}
}
}
</code></pre>
<p>or using <code>:nth-child(1)</code> instead. Nothing works. I'm clueless. Somewhere else in my SASS, I have the following:</p>
<pre><code>.tab-content {
>.tab-pane:first-child > form > div.row > div {
// rules here
> div.picture-container {
// rules here
}
}
>.tab-pane {
// rules here
}
>.tab-pane:nth-child(4) > form {
// rules here
}
}
</code></pre>
<p>Which is working just fine. So I really don't get what I'm doing wrong in the first example. Anyone able to help?</p>

Redirect child process's stdin and stdout to pipes
|
<hr>
<p>EDIT:
The solution is </p>
<pre><code> int c1=dup2(pipes[0][1],STDOUT_FILENO);
int c2=dup2(pipes[1][0],STDIN_FILENO);
setvbuf(stdout,NULL,_IONBF,0);
</code></pre>
<p>It is SETVBUF to set stdout to be non-buffered. Even though I was printing the newline character if the destination is not an actual screen, I guess, it becomes buffered. </p>
<hr>
<hr>
<p>EDIT:
When I put <strong>fflush(stdout)</strong> after LINE 1 and <strong>fflush(fout)</strong> after LINE 4 it works as expected. However, it does not work without the <strong>fflush(stdout)</strong> after LINE 1. The problem is that I would not be able to put <strong>fflush</strong> in the program which I am planning to run.</p>
<hr>
<p>I am trying to start another program from my process. I don't have access to its code but I know it uses stdin and stdout for user interaction. I am trying to start that program by creating 2 pipes, fork-ing and redirecting the child's stdin/stdout to the proper pipe ends. The points is that the parent should be able communicate with the child via file descriptors, while its stdin/stdout should be intact. The POPEN syscall only opens unidirectional pipe. The following code almost works. </p>
<p>There are 4 lines marked as LINE 1..4.</p>
<p>LINE 1 is child sending to pipe,
LINE 2 is child receiving from pipe,
LINE 3 is parent sending to pipe,
LINE 4 is parent receiving from pipe,</p>
<p>This is just a toy example to make sure things work. The issue is that is all 4 lines LINE1..4 are uncommented the output I see on the terminal is </p>
<pre><code>PARENT1: -1
FD: 1 0 4 5 0 1
DEBUG1: 0
DEBUG2: 0
</code></pre>
<p>While if LINE 1 and LINE 3 are uncommented only I see a continuous stream of data. Same happens if if only LINE 2 and LINE 4 are uncommented. However, I want a full bidirectional communication. Also adding the commented SLEEP does not change the behavior. </p>
<p>What could be the issue here. I wonder why is there no bidirectional POPEN.</p>
<pre><code>int pid;

<p>When I use this command:</p>
<pre><code># ffmpeg -i "http://example.com/chunklist.m3u8" file.mp4
frame= 582 fps=9.4 q=28.0 size= 1536kB time=00:00:23.21 bitrate= 542.1kbits/s dup=2 drop=4 speed=0.375x
</code></pre>
<p>It works. But It get frame by frame video and very long time needed. (It takes time almost to playback the video.)</p>
<p>But since the path of all the <code>.ts</code> files are known. (<a href="http://example.com/media_0.ts" rel="noreferrer">http://example.com/media_0.ts</a>, <a href="http://example.com/media_1.ts" rel="noreferrer">http://example.com/media_1.ts</a>, ...) There must be a way to get and merge them all at the same time.</p>
<p>But How in <a href="http://ffmpeg.org/" rel="noreferrer"><code>ffmpeg</code></a> directly?!</p>
<h3>EDIT (try a solution):</h3>
<p>For one solution, I know how can concatenation files with ffmpeg.</p>
<pre><code>ffmpeg -i "concat:0.ts|1.ts|2.ts|3.ts|4.ts|5.ts" -c copy output.mp4
</code></pre>
<p>This ffmpeg command was great, and works in less 1 sec time!</p>
<p>So try to download all <code>.ts</code> files with CURL with this command:</p>
<pre><code>curl \
http://example.com/media_0.ts -o 0.ts \
http://example.com/media_1.ts -o 1.ts \
http://example.com/media_2.ts -o 2.ts \
http://example.com/media_3.ts -o 3.ts \
http://example.com/media_4.ts -o 4.ts \
http://example.com/media_5.ts -o 5.ts
</code></pre>
<p>But you can see result:</p>
<pre><code> % Total % Received % Xferd Average Speed Time Time Time Current

</code></pre>
<p>See, total download time was 72 sec, while the total duration of all parts is 59 sec! that this time is very long!</p>
<p>So sorry, download all parts and then concat that, was not good solution.</p>
<h3>EDIT 2</h3>
<p>I try for another <code>.m3u8</code> file on the another server with difference URL:</p>
<p>Download and concat together:</p>
<pre><code>ffmpeg -i "concat:\

</code></pre>
<p>Another command with <code>input.txt</code> URLs file.</p>
<pre><code>ffmpeg -f "concat" -i "input.txt" -c copy -y output.ts
</code></pre>
<p>input.txt file:</p>
<pre><code>file 'http://184.72.239.149/vod/smil:BigBuckBunny.smil/media_w442897525_b560000_0.ts'

<p>Or this command some time if needed:</p>
<pre><code>ffmpeg -f "concat" -safe "0" -protocol_whitelist "file,http,https,tcp,tls" -i "input.txt" -c copy -y output.ts
</code></pre>
<p>Finally, for that download speed was good, <strong>MAYBE my server target has limited bandwidth. :-(</strong></p>

Get the current array key inside foreach
|
<p>Ok so, I am building something for my employer for them to input products, they have very specific requirements. I have a form with dynamically generated fields like so...
(obviously not the exact code to follow but the examples are identical conceptually)</p>
<pre><code><input type="text" name="attribute[20]"> inputted value = height
<input type="text" name="attribute[27]"> inputted value = width
</code></pre>
<p>the numbers are generated based on things in the database, so 20 would correlate to "width" 27 would correlate to "height" for example.</p>
<p>So once the user enters the values I need those values to go into a database...or in the test, echo out.</p>
<pre><code>foreach ($_POST['attribute'] as $attributes){
echo key($attributes).' '.$attributes.'<br>';
}
</code></pre>
<p>So that should output...</p>
<pre><code>20 height value<br>
27 width value
</code></pre>
<p>but instead it outputs</p>
<pre><code>&nbsp;height value<br>
&nbsp;width value
</code></pre>
<p>What is going on? I have something similar...but slightly different as the defined numbers can have more than one input....which works perfectly.</p>
<pre><code><input type="text" name="option[][20]"> inputted value = option 1
<input type="text" name="option[][20]"> inputted value = option 2
<input type="text" name="option[][27]"> inputted value = option 1
foreach ($_POST['option'] as $options){
echo key($options).' ';
foreach ($options as $option){
echo $option.'<br>';
}
</code></pre>
<p>which outputs perfectly...</p>
<pre><code>20 option 1<br>
20 option 2<br>
27 option 1
</code></pre>
<p>I don't understand why the more complex one works and the simpler one doesn't, am I missing something obvious? I am aware I have a somewhat unorthodox method of coding in comparison to some, but it is what it is lol. Any help would be greatly appreciated.</p>
<p>EDIT: Var dump as requested</p>
<p>array(22) { ["pID"]=> string(12) "test product" ["pPrice"]=> string(0) "" ["pName"]=> string(0) "" ["pRRP"]=> string(0) "" ["pPostSize"]=> string(0) "" ["pOurPrice"]=> string(0) "" ["pEstDelivery"]=> string(0) "" ["pWeight"]=> string(0) "" ["pEAN"]=> string(0) "" ["pOrder"]=> string(0) "" ["pStock"]=> string(0) "" ["pManufacturer"]=> string(0) "" ["pType"]=> string(13) "Shower Valves" ["pRange"]=> string(0) "" ["cat"]=> array(2) { [0]=> string(2) "72" [1]=> string(2) "23" } ["attribute"]=> array(2) { [<strong><em>0</em></strong>]=> string(5) "<strong><em>width</em></strong>" [1]=> string(6) "height" } ["option"]=> array(3) { [0]=> array(1) { [<strong>11</strong>]=> string(6) "<strong>works1</strong>" } [1]=> array(1) { [<strong>10</strong>]=> string(6) "<strong>works1</strong>" } [2]=> array(1) { [<strong>10</strong>]=> string(6) "<strong>works2</strong>" } } ["pLongdescription"]=> string(0) "" ["meta_description"]=> string(0) "" ["meta_keyword"]=> string(0) "" ["meta_title"]=> string(0) "" ["action"]=> string(6) "create" }</p>
<p>the bold parts, are the parts that successfully come out in my second example. but the bold italic as you can see, returns 0 instead of the 20 that is actually in the form name value.</p>

`TypeError` when calling create(). You may need to make the field read-only, or override the create() method
|
<p>Not sure what's going on here. I'm trying to perform create a new instance via Django-rest-framework. <strong>What am I doing wrong?</strong></p>
<p>There are a few read-only fields being submitted back.
I've tried marking them as read-only via <code>read_only_fields</code> in the serializer, as well as specifying them as <code>editable=False</code> within the model's fields.</p>
<p>Note: I would prefer to avoid specifying my own create method if possible. This should work via standard functionality as documented <a href="http://www.django-rest-framework.org/api-guide/serializers/#specifying-read-only-fields" rel="noreferrer">here</a></p>
<p>when POSTing the following:</p>
<pre><code>{
"displayName": "New test",
"backgroundColour": "#4d3567",
"foregroundColour": "#FFFFFF",
"helpText": "test",
"description": "test",
"comment": "test."
}
</code></pre>
<p>i'm getting:</p>
<pre><code>TypeError at /api/v1/classifications/
Got a `TypeError` when calling `ClassificationLabel.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `ClassificationLabel.objects.create()`. You may need to make the field read-only, or override the ClassificationLabelListSerializer.create() method to handle this correctly.
