Django admin site is not showing default permissions of models
|
<p>My Django admin site does not show any default permissions of any models. Actually, I checked the database and I can't find any model permission in the <code>auth_permissions</code> table.</p>
<p>I've already run <code>python manage.py makemigrations</code> and <code>python manage.py migrate</code>. I also tried deleting the database and migration files and run two above command again but doesn't work. I've already registered my models in admin.py.</p>
<p>Any other solutions I can try ?</p>
<p>admin.py</p>

# Register your models here.

Get a .txt from the Internet, compare it and open a dialog in an AsyncTask
|
<p>I want to check, if there is an update for my app. For this I put up an txt file online with just an integer of the latest app version. This should get compared with the running app version and when there is a newer version, open a dialog for the user to give the choice of open a link to the new .apk in the browser or to cancel it. It's giving me trouble and I don't know what to do. Thanks for helping me out! </p>
<p>The AsyncTask:</p>
<pre><code>public class UpdateCheck extends AsyncTask <Void, Void, Boolean> {

// Read all the text returned by the server
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
while ((str = in.readLine()) != null) {
// str is one line of text; readLine() strips the newline character(s)
}
in.close();
} catch (MalformedURLException e) {
} catch (IOException e) {

<hr>
<p>I just added some Log-Tags to the code and saw, that it is working until the <code>Integer.parseInt(str)</code>. At this time <code>str</code> is <code><html></code>, I don't know where this comes from, because when I look up the source code of my "page" it says just the number...`</p>
<p>I solved it by changing the <code>while</code> loop to <code>while ((str = in.readLine()) != null) { sb.append(str); }</code> and <code>Integer.parseInt(sb.toString())</code>.</p>

Angular: E2E Test via login page

<p>I have an Angular application using an Express.js backend. It features a default address pathway to a login page <code>/avior/login</code>.

Listview taking too long to update C#

<p>I have a problem I have been stuck on for ages, was hopinh you can all help please.</p>
<p>I have a listview which populates with data from my database upon the programs first load.</p>
<p>In my program I have a button which 'Refreshes' this listview by wiping all of the data out of the listview and running the same method which populates the listview upon program load. However, this refresh button is taking far too long (about 10 seconds) to refresh. </p>
<p>How is it that the program can load in 2 seconds with the listview populated however when running the method again it takes much longer.</p>
<p>Please see my attached code and suggest any changes, I apologise for the length. Thank you.</p>

<p>I am trying to solve this system of SDEs in R, dX = (-X*a + (Y-X)<em>b + h)dt + g dW and dY = (-Y</em>a + (X-Y)*b)dt for time [0,200], a=0.30, b=0.2, g=1 and h is 1 for time [50,70] and 0 otherwise. I have the following code for the system for constant h=1:</p>
<pre><code>library(diffeqr) ##for solving ODEs SDEs DDEs..
library(deSolve)
library(Julia) ##used for the sde
library(JuliaCall)

#u0 is the starting value for the vector
#func1 is the ODE TO SOLVE
#f is the drift part in the sde

</code></pre>
<p>I am not sure how to include the time dependence of <code>h</code>, I tried to do it by including a <a href="https://stackoverflow.com/questions/69843063/how-to-solve-a-system-of-ode-with-time-dependent-parameters-in-r/69846444#69846444">forcing variable</a> but I got a lengthy Julia error (stating that <code>h</code> is not defined- code below) . So perhaps thats not the way to go. I'd appreciate any help regarding this.</p>
<p>The chunk of the code I changed to include the time dependent parameters is this (the new or changes lines have an arrow to their right):</p>
<pre><code>## drift part in the SDE
f <- JuliaCall::julia_eval("
function f(dy,y,p,t)
MU <- signal(t) # <-
dy[1] = -y[1]*p[1] + (y[2]-y[1])*p[2] + MU # <-
dy[2] = -y[2]*p[1] + (y[1]-y[2])*p[2]
end")
signal <- approxfun(x = c(0, 35, 125, 200), # <-
y = c(0, 1, 0, 0),
method = "constant", rule = 2)
## diffusion part in the SDE
g <- JuliaCall::julia_eval("
function g(dy,y,p,t)
dy[1,1] = p[3]
dy[2,1] = 0
end")
## matrix associated to the noise
noise_rate_prototype <- matrix(rep(1,2), nrow = 2, ncol = 1)
tspan <- c(0,200)
JuliaCall::julia_assign("u0", u0); ## initial value
JuliaCall::julia_assign("tspan", tspan); ## grid

## call the SDE problem
prob <- JuliaCall::julia_eval("SDEProblem(f, g, u0,tspan,p, noise_rate_prototype=noise_rate_prototype, signal=signal)"); # <-

Reload <ul> with event handler function
|
<p>I am extremely new to JavaScript/HTML/CSS. As a first website project I am working on my online shop using Shopify.</p>
<p><a href="https://tpvm5oi54gjh03pr-51451003036.shopifypreview.com/collections/lo-mas-popular/products/cilindro" rel="nofollow noreferrer">This is My Website</a></p>
<p>I am trying to update the list of images (thumbnails below the main picture) after one of the options is changed (size or color).</p>
<p>I have managed to display the correct images when the page first loads by using the alt_text of each figure. For example, if you change the options and reload the website, you will see the appropriate figures. I did that as follows:</p>
<pre><code>{% assign wanted_alts = product.selected_or_first_available_variant.options %}
<ul>
{% for media in product.media %}
{% if wanted_alts contains media.alt or media.alt == "All" %}
<li>
...
</li>
{% endif %}
{% endfor %}
</ul>
</code></pre>
<p>Basically, I just load the images that have an alt_text equal to the selected options.</p>
<p>I now want to change all the thumbnails when an option is selected e.g. you select a different color. At the moment it only works if you</p>
<ol>
<li>First select the options.</li>
<li>Then you refresh the page.</li>
</ol>
<p>I want the list to update automatically. I was able to find that the event of choosing another option is handled by this function:</p>
<pre><code>_onSelectChange: function() {
var variant = this._getVariantFromOptions();
this.container.dispatchEvent(
new CustomEvent('variantChange', {
detail: {
variant: variant
},
bubbles: true,
cancelable: true
})
);
if (!variant) {
return;
}
this._updateMasterSelect(variant);
this._updateImages(variant);
this._updatePrice(variant);
this._updateSKU(variant);
this.currentVariant = variant;
if (this.enableHistoryState) {
this._updateHistoryState(variant);
}
}
</code></pre>
<p>I want to achieve something like (forgive my ignorance):</p>
<pre><code>_onSelectChange: function() {
...
/* Reload the <ul> tag that sets which figures to display */
}
</code></pre>
<p>Can someone point me into the right direction?</p>
<p><strong>EDIT:</strong>
I have been able to get the desired behaviour (in a non-optimal way) with the following:</p>
<pre><code>_onSelectChange: function() {
...
location.reload();
}
</code></pre>
<p>Which reloads the entire page.</p>
<p>I have tried to reload just the <code><ul></code>, but I don't know how to do it. I have tried the following, but it didn't work:</p>
<pre><code><div id="myID">
{% assign wanted_alts = product.selected_or_first_available_variant.options %}
<ul>
{% for media in product.media %}
{% if wanted_alts contains media.alt or media.alt == "All" %}
<li>
...
</li>
{% endif %}
{% endfor %}
</ul>
</div>
</code></pre>
<p>And:</p>
<pre><code>_onSelectChange: function() {
...
$('#myID').load(document.URL + ' #myID');
}
</code></pre>
<p>Any help is appreciated.</p>

Xamarin Essentials MediaPicker not working on iOS
|
<p>I'm using Xamarin Essentials MediaPicker (v1.7.3) on my Xamarin Forms 5 app and it just freezes and eventually crashes the app on iOS but works perfectly fine on Android.</p>
<p>My app uses the <code>MVVM</code> pattern so I have an <code>ImageButton</code> that's wired to a method in my view model and the code for that method looks like this:</p>
<pre><code>async Task Add_Image_Tapped()
{
try
{
var photosPermission = await Permissions.CheckStatusAsync<Permissions.Photos>();
var cameraPermission = await Permissions.CheckStatusAsync<Permissions.Camera>();
if (photosPermission != PermissionStatus.Granted || photosPermission != PermissionStatus.Restricted)
photosPermission = await Permissions.RequestAsync<Permissions.Photos>();
if (cameraPermission != PermissionStatus.Granted || cameraPermission != PermissionStatus.Restricted)
cameraPermission = await Permissions.RequestAsync<Permissions.Camera>();
if ((photosPermission == PermissionStatus.Granted
|| photosPermission == PermissionStatus.Restricted)
&& (cameraPermission == PermissionStatus.Granted
|| cameraPermission == PermissionStatus.Restricted))
await HandleImagePicker();
}
catch(Exception e)
{
throw new Exception(e.Message);
}
}
</code></pre>
<p>And if the permissions check out fine, here's the method that handles the image pick up:</p>
<pre><code>private async Task HandleImagePicker()
{
try
{
var filePath = string.Empty;
var fileName = string.Empty;
MainThread.BeginInvokeOnMainThread(() => {
var result = MediaPicker.PickPhotoAsync(new MediaPickerOptions
{
Title = "Pick Image"
}).Result;
if (result == null)
return;
filePath = result.FullPath;
fileName = result.FileName;
});
if (!string.IsNullOrEmpty(filePath) && !string.IsNullOrEmpty(fileName))
{
// Do something with the image
}
}
catch(Exception e)
{
throw new Exception(e.Message);
}
}
</code></pre>
<p>I'm using <code>Xamarin Forms 5.0.0.2401</code>, <code>Xamarin Community Toolkit 2.0.2</code> and <code>Xamarin Essentials 1.7.3</code>. I also have the following permissions in my <code>Info.plist</code>:</p>
<pre><code><key>NSCameraUsageDescription</key>
<string>MyApp would like to access your camera</string>
<key>NSMicrophoneUsageDescription</key>
<string>MyApp would like to access your microphone</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>MyApp would like to access your photo library</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>MyApp would like to access your photo library</string>
</code></pre>
<p>I also initialize Xamarin Essentials in <code>AppDelegate</code> <code>FinishedLaunching()</code> method as below:</p>
<pre><code>Xamarin.Essentials.Platform.Init(() => new UIViewController());
</code></pre>
<p>Any idea what maybe the issue here?</p>
<p>UPDATE:</p>
<p>The above code reflects the current code I have after making changes based on suggestions such as using the main thread.</p>
<p>Currently, if I run the app on iOS Simulator on a Mac, it literally hangs forever. Never throws an exception or crashes.</p>
<p>If I run it on a real device i.e. iPhone Xs, it will hang for quite a while and eventually crash the whole app.</p>
<p>As mentioned earlier, it all works perfectly fine on Android.</p>

Firebase Crashlogs leads me astray (iOS crash log)
|
<p>I have a bug in my app which I am not able to reproduce on my own device and the firebase crash log doesn't really help me. Or maybe I am not able to understand it correctly. What is really weird is that it tells me lines of code where the crash happens which is in the millions.</p>
<pre><code>Crashed: com.apple.main-thread
</code></pre>
<p>0 Flax 0x102359394 CategoriesViewController.loadPosts(more:) + 4338652052 (CategoriesViewController.swift:4338652052)</p>

<p>14 libdyld.dylib 0x186ea0cf8 start + 4</p>
<p>The crash happens rarely. The two lines which make sense (361 (CategoriesViewController.swift:361) and PostsAPI.loadPostsOrdered(start:order:limit:category:controller:onSuccess:) + 342 (PostAPI.swift:342) are actually empty lines which makes it even more confusing.</p>
<p>Like I said those functions are called thousands of times a day and crash maybe every 1000th time.</p>
<p>Any idea how to understand this crash log?</p>
<p>edit: The HashtagTableviewCell</p>
<pre><code>import Foundation
import KILabel
class HashtagTableViewCell: UITableViewCell {
@IBOutlet weak var hashtagCounter: UILabel!
@IBOutlet weak var HashTagLabel: UILabel!
var hashtag: Hashtag!

<pre><code>var u = SessionManager.Session.QueryOver<User>().Where(x => x.Id == 1).
SelectList(list => list.
Select(x => x.Login).WithAlias(() => result.CreateUser))
.TransformUsing(Transformers.AliasToBean<ExpenseDetailsItemVm>())
.List<ExpenseDetailsItemVm>();
</code></pre>
<p>And this also works fine.</p>
<p>In my <code>Expenditure</code> table, the column <code>CreateUser_Id</code> everywhere has a value</p>

Django images uploaded by admin will not display in production or development
|
<p>I have Django 1.10 and whitenoise 3.3 and the website is deployed on Heroku. My static files are fine in development and production. My media files, however do not load in production and development. </p>
<p>When debug = True, the media files render properly in both production and development. What I really want is for the media files to render properly even when debug = False. </p>
<p>Everything was fine and dandy until I realized I deployed my site with debug = True. So, I changed it to debug = False. Now the static and media files failed. I did some research and went to whitenoise docs to follow setup. Then the static files worked. However, the media files still failed. I read the docs on media and static files on Django, but unfortunately only saw some samples with nginx and the doc says there are many ways to do this and can only provide structure. </p>
<p>I am seeking a solution that will allow me to continue to add things to my site in production via admin and still allow my to run my website with heroku. </p>

I am interested in what we are able to learn from data. I am looking to join a data science team that shares this interest and satisfaction gained when making predictions that would otherwise not be possible without analyzing data. Statistics, machine learning, artificial intelligence, computer vision, and computational geometry are my fields of interest.

Adding items to VB.NET ListView and having them shown in the order they were added
|
<p>I am creating an app launcher - that is basically a ListView with a "group" of shortcuts files ( ie images associated with a shortcut and the text is the name of the shortcut ) in it. It's all been working fine and dandy, except this last thing that I want to do. The apps that appear in the listview are stored in an xml file and what I'm trying to do is add the apps into the listview in the order they appear in the xml file i.e. this probably won't be alphabetical.</p>
<p>So I read an app name from the xml file, find it's shortcut lnk file, extract the icon from the file and add it to the Listview; using:</p>
<pre><code>lvPrograms.LargeImageList = ProgramIcons
Dim item As ListViewItem
Dim FileName = Path.GetFileNameWithoutExtension(shortcutFile.Name)
item = New ListViewItem(FileName, 1)
item.ImageKey = FileName
iconFile = System.Drawing.Icon.ExtractAssociatedIcon(shortcutFile.FullName)
ProgramIcons.Images.Add(FileName, iconFile)
lvPrograms.Items.Add(item)
</code></pre>
<p>I also set the Sorting property of the listView to None</p>
<p>When the code has added all the apps, I was hoping for them to appear in the order I added them, but it just seems to add them in a random order ie.. not my order or ascending or descending ?!</p>
<p>If I check the contents of lvPrograms.Items(X).Text in the debug window, then (0) is not the first one I added and (6) is not the seventh one I added ?!</p>
<p>Hope this makes sense and someone could help me get the apps listed in the order that I added them ?</p>
<p>Cheers,</p>
<p>Chris.</p>
<p>Extra Info asked for my Plutonix:</p>
<p>Basically my xml is read into an object called UserAppSettings which has a collection of Application objects and their Name property if the name of the app. Also the ProgramDetails is a structure that holds various properties about a shortcut - name, working folder etc </p>
<p>The image lists (in case relevant are 32bit & 16bit in depth )</p>
<pre><code> lvPrograms.Clear()
ProgramIcons.Images.Clear()
ProgramIconsSmall.Images.Clear()
lvPrograms.LargeImageList = ProgramIcons
lvPrograms.SmallImageList = ProgramIconsSmall
Dim dir As New System.IO.DirectoryInfo(userShortcutsFolder)
lvPrograms.BeginUpdate()
lvPrograms.Sorting = SortOrder.None
Dim shortcutFile As FileInfo
For Each AppToShow As Application In UserAppSettings.Applications
shortcutFile = New FileInfo(userShortcutsFolder + AppToShow.Name + ".lnk")
addShortcutToListView(shortcutFile)
Next
Private Sub addShortcutToListView(shortcutFile As FileInfo)
Dim CurrentProgram As ProgramDetails
Dim item As ListViewItem
CurrentProgram = New ProgramDetails
With CurrentProgram
.FullName = shortcutFile.FullName
.Name = shortcutFile.Name
.NameWithoutExtension = Path.GetFileNameWithoutExtension(shortcutFile.Name)
item = New ListViewItem(.NameWithoutExtension, 1)
.Icon = System.Drawing.Icon.ExtractAssociatedIcon(.FullName)
getShortcutProperties(CurrentProgram)
ProgramIcons.Images.Add(.NameWithoutExtension, .Icon)
ProgramIconsSmall.Images.Add(.NameWithoutExtension, .Icon)
item.ImageKey = .NameWithoutExtension
End With
item.Tag = CurrentProgram
lvPrograms.Items.Add(item)
' MsgBox(item.Text + vbNewLine + lvPrograms.Items(lvPrograms.Items.Count - 1).Text)
End Sub

how do I output the filtered todo list in React TypeScript

<p>It is console logging the right array out all the time, but the point here is that it should be outputting that in the 'TodoList.tsx'. Not sure how to get that fixed in this case. Anyone who could help me with this. To see the bigger picture, please click on this link:</p>

Azure DevOps WorkItem Tracking not working when code generated
|
<p>I have a problem with azure devops workitem tracking.
So we want to use WorkItem tracking for work items, that do not need changes in our source code.</p>
<p>Currently we are tracking Builds and Releases with C# and the <code>Microsoft.TeamFoundation.WorkItemTracking</code> NuGet packages.</p>
<p>The visualization for the build tracking is ok, but the deployments won´t show in the details pane of a ticket.</p>
<p>OK</p>
<p><img src="https://i.stack.imgur.com/tAlfN.png" alt="Ticket related with code" /></p>
<p>Not OK</p>
<p><img src="https://i.stack.imgur.com/dhM7c.png" alt="Ticket related with CI/CD" /></p>
<p>The relations both in azure devops and as shown in the debugger seem to be the same:</p>
<p><img src="https://i.stack.imgur.com/AIpMN.png" alt="Ticket Links from ticket related in code" /></p>
<p>This is our patch operation:</p>
<pre><code>new JsonPatchOperation()
{
Operation = Operation.Add,
Path = "/relations/-",
Value = new
{
rel = "ArtifactLink",
url = "vstfs:///ReleaseManagement/ReleaseEnvironment/" + temp.Href.Split('/')[4] + ":"+ release.Id + ":" + environment.Id,
attributes = new
{
authorizedDate = DateTime.Now,
//comment = "This build was automatically linked to this work item based on the Tool",
resourceCreatedDate = DateTime.Now,
resourceModifiedDate = DateTime.Now,
name = "Integrated in release environment",
revisedDate = new DateTime(9999, 1, 1, 0, 0, 0, 0)
}
}
}
</code></pre>
<p>What should I do, to have the related Release displayed in the details pane of the ticket?
I compared every attribute while debugging with a sample ticket I created with CI/CD, every link and relation is OK. Builds are shown, releases not.</p>

Visual Studio Online Build and Release - Copy files to another project
|
<p>In a solution, I have three projects (for the sake of this example):</p>
<h3>- MyWebJob</h3>
<h3>- MyFrontendWebsite</h3>
<h3>- MyBackendWebsite</h3>
<ul>
<li>/Views/EmailTemplates/SomeEmailTemplate.cshtml (file in MyBackendWebsite)</li>
</ul>
<p>When deployed, <strong>MyWebJob</strong> runs as we webjob below <strong>MyFrontendWebsite</strong>.</p>
<p>However, it needs the email templates from the <strong>MyBackendWebsite</strong> Emailtemplates folder.</p>
<hr />
<p>I think the solution could be...:</p>
<ol>
<li>Publish the EmailTemplates as an artifact.</li>
</ol>
<p><a href="https://i.stack.imgur.com/Vbbcc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Vbbcc.png" alt="enter image description here" /></a></p>
<ol start="2">
<li>During release, copy that artifact to the webjob folder, using a "Copy Files" task.</li>
</ol>
<p><a href="https://i.stack.imgur.com/l9QUL.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/l9QUL.png" alt="enter image description here" /></a></p>
<p>The problem is, I don't know what to enter in the Target Folder.</p>
<p>Using KUDU, I know that the webjob is stored in<br />
D:\home\site\wwwroot\app_data\jobs\continuous\MyWebJob, but setting that as the target folder does not copy anything, despite the release log file telling me it did copy the file to that folder...</p>

</code></pre>
<p>What am I missing here? How do I copy that email template to where the webjob can get to it?</p>
<p>Pre-empting what I myself would have asked...:</p>
<p>Q: Why not just put the templates in the webjob project in the first place?</p>
<p>A: Because the template is actually used in the MyBackendWebsite as well, to preview emails.</p>

Client not receiving new message sent from Controller after save

Firebase Database Get All Value In Order Cloud Functions
|
<p>I develop for Firebase Cloud Functions. I have a Firebase Realtime Database like this:</p>
<pre><code>----- myData
-------eqewrwrepere (this one is a device token)
---------Lta+sde-fer (this one is a firebase id)
firstvalue : "a"
secondvalue : "b"
----------Qrgd+ad-qdda (this one is second firebase id)
firstvalue : "c"
secondvalue : "d"
-------eqwerSAsdqe (this one is another device token)
---------Lta+sde-fer (this one is a firebase id)
firstvalue : "x"
secondvalue : "y"
----------Qrgd+ad-qdda (this one is second firebase id)
firstvalue : "z"
secondvalue : "t"
</code></pre>
<p>I fetch these data by this code. With this code i fetch all data and put them an array. And when fetching done, i loop this array for finding items. I am an iOS developer, so i am a newbie for NodeJS. Here is what i want to do:</p>
<ol>
<li>Get <code>firstvalue</code> for each database data.</li>
<li>Make a api request with firstvalue of each database data.</li>
<li>Api returns an image.</li>
<li>Write image temp directory.</li>
<li>Process this image for visionApi.</li>
<li>Extract text.</li>
<li>Update database.</li>
<li>Send notification for deviceToken</li>
</ol>
<p>Now i am able to retrieve database items in my array. When i make a request in for loop, request called async. So for loop continues, but request response or writing file and vision processing executed only once. </p>
<p>In for loop, get databasearray[0], make request, write file, process it with vision api, update database and go for next databasearray[1] item.</p>
<p>I read about <code>Promises</code> on different pages. But i did not understand.</p>
<p>Thank you.</p>

Draggable text box scales more than expected
|
<p>I made a text box and boxes on the corners for resizing. The first time I drag, it works perfectly fine, but after the 1st time, the dragging amount seems to multiply. (Don't mind the position of the dragging nodes). If you drag once, it scales fine with the mouse. It seems as if every time after that, when you drag, it scales farther and farther from the user's mouse, causing an 'uncontrollable' scale. I reset the values of the prevX and prevY values at the end of the move function. I'm not sure if that's the issue though. The issue, I believe, is with the scaling with getBoundingClientRect() in the resize portion. Moving the textbox, however, works perfectly fine. Here is my code:</p>

Prevent related records being updated in Entity Framework
|
<p>I have an entity (Skill) which has a relationship to another entity (Game):</p>
<pre><code> public class Skill
{
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Key]
public Guid Id { get; set; }
public virtual Game Game { get; set; }
public virtual IdentityUser TeamMember { get; set; }
public int SkillPoints1 { get; set; }
public int SkillPoints2 { get; set; }
public int SkillPoints3 { get; set; }
public int SkillPoints4 { get; set; }
public int SkillPoints5 { get; set; }
public bool Spectator { get; set; }
public Skillset SelectedSkillNumber { get; set; }
}
</code></pre>
<p>The Game entity also has related entities:</p>
<pre><code> public class Game
{
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Key]
public Guid Id { get; set; }
public string GameTitle { set; get; }
public DateTime Created { get; set; }
public GameState GameState { get; set; }
public virtual Team GameTeamMembers { get; set; }
public virtual IdentityUser GameOwner { get; set; }
public virtual ICollection<Backlog> ProductBacklog { get; set; }
</code></pre>
<p>At some point, I'm loading in the "Skills" for a particular Game, so I have to include the game record in order to return the Skill records:</p>
<pre><code>List<Skill> allSkillsets = _context.Skills.Include(x => x.Game).Where(x => x.Game.Id == gameId).Include(x => x.TeamMember).ToList();
</code></pre>
<p>However, when I'm looping through these records to update some of the properties, EF tries to update the "Game" record as well:</p>
<pre><code> foreach (Skill player in allSkillsets)
{
try
{
player.SkillPoints1 = player.SelectedSkillNumber == Skillset.Skill1 ? 5 : boost_skillset1_by + 1;
player.SkillPoints2 = player.SelectedSkillNumber == Skillset.Skill2 ? 5 : boost_skillset2_by + 1;
player.SkillPoints3 = player.SelectedSkillNumber == Skillset.Skill3 ? 5 : boost_skillset3_by + 1;
player.SkillPoints4 = player.SelectedSkillNumber == Skillset.Skill4 ? 5 : boost_skillset4_by + 1;
player.SkillPoints5 = player.SelectedSkillNumber == Skillset.Skill5 ? 5 : boost_skillset5_by + 1;
//_context.Entry(player.Game).State = EntityState.Detached;
_context.Entry(player.Game).State = EntityState.Unchanged;
_context.Skills.Attach(player);
_context.Entry(player).Property(x => x.SkillPoints1).IsModified = true;
_context.Entry(player).Property(x => x.SkillPoints2).IsModified = true;
_context.Entry(player).Property(x => x.SkillPoints3).IsModified = true;
_context.Entry(player).Property(x => x.SkillPoints4).IsModified = true;
_context.Entry(player).Property(x => x.SkillPoints5).IsModified = true;
await _context.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
_logger.LogErrorWithObject("Could not write backlog item to database", "UpdatePlayerSkills", player);
throw;
}
</code></pre>
<p>Because the "Game" entity doesn't have all of it's related entities loaded in (e.g. ProductBacklog), the update wipes out all of these records.
Is there a way I can just update the 5 properties in the Skill record, without also updating it's related Game record?</p>
<p>I've also tried setting Game to null, but then this removes the Id in the foreign key column</p>

How to make a selector of extended state from a entity feature inside ngrx?
|
<p><strong>Problem:</strong>
This selector <code>entity.selectAll</code> will not include the extended state.</p>
<h2><strong>Question:</strong></h2>
<p><strong>How do I include my extend state inside selectAll OR how can I create a custom selector for my selected state?</strong></p>
<p>My UxeGallery Model is: </p>
<pre><code>export interface UxeGallery {
id: string;
imgSrc: string;
name: string;
details?: string;
}
</code></pre>
<p>Here I have my EntityState and I have added some state to it:</p>
<pre><code>export interface State extends EntityState<UxeGallery> {
selectedItem: string | null;
hiddenItem: string | null;
bottombarTemplate: boolean;
topbarTemplate: boolean;
topbarTemplateType: string;
modalTemplate: boolean;
canvasTemplate: boolean;
canvasImg: string | null;
}
</code></pre>
<p>I create the adapter:</p>
<pre><code>export const adapter: EntityAdapter<UxeGallery> = createEntityAdapter<UxeGallery>();
</code></pre>
<p>Set the init state:</p>
<pre><code>export const initialState: State = adapter.getInitialState({
ids: ['0'],
entities: {
'0': {
imgSrc: 'url',
name: 'dog',
details: 'some dog',
}
},
selectedItem: null,
hiddenItem: null,
topbarTemplateType: TopbarType.WHITE,
topbarTemplate: false,
bottombarTemplate: false,
modalTemplate: false,
canvasTemplate: false,
canvasImg: null,
});
</code></pre>
<p>Create my featureSelector:</p>
<pre><code>export const getState = createFeatureSelector<any>('uxeGallery');
</code></pre>
<p>Export adapter selectors:</p>
<pre><code>export const {
selectIds,
selectEntities,
selectAll,
selectTotal,
} = adapter.getSelectors(getState);
</code></pre>
<p>From my app component I selectAll from my entity:</p>
<pre><code>import * as fromUxeGallery from '../../reducers/uxe-gallery.reducer';
import { UxeGallery } from '../../uxe-gallery.model';
export class UxeGalleryMasterComponent implements OnInit {
private obs: Observable<UxeGallery[]>;
private obsExtended: Observable<any>;
constructor(private store: Store<fromUxeGallery.State>) { }
ngOnInit() {
this.obs = this.store.pipe(select(fromUxeGallery.selectAll));
this.obs.subscribe(console.log);
/**
This will return
[
{
details:"some dog",
imgSrc:"url",
name:"dog"
}
]
*/
}
}
</code></pre>
<p><strong>How can I make a selector that will grab the extended state from my Entity model?</strong></p>
<p>e.g</p>
<pre><code> selectedItem: null,
hiddenItem: null,
topbarTemplateType: TopbarType.WHITE,
topbarTemplate: false,
bottombarTemplate: false,
modalTemplate: false,
canvasTemplate: false,
canvasImg: null,
</code></pre>
<p>UPDATE:</p>
<p>I added this:</p>
<pre><code>export const getState = createFeatureSelector<any>('uxeGallery');
export const selectFeatureExtended = createSelector(getState, (state: State) => {
return {
selectedItem: state.selectedItem,
hiddenItem: state.hiddenItem,
bottombarTemplate: state.bottombarTemplate,
topbarTemplate: state.topbarTemplate,
topbarTemplateType: state.topbarTemplateType,
modalTemplate: state.modalTemplate,
canvasTemplate: state.canvasTemplate,
canvasImg: state.canvasImg,
};
});
</code></pre>
<p>It feels pretty verbose but if theres no other solution it works as intended :(</p>

How to avoid reading data from R environment within Rcpp function
|
<p>Even though <code>MyCppFunction(NumericVector x)</code> returns the desired output, I am not sure of a proper/efficient way to avoid reading the data on variable <code>myY</code> withou passing it as a function argument.</p>
<p>The reason I do not pass the data as an argument is that I will eventually pass the C++ function as an objective function to minimize and the minimization routine accepts a function of one argument only, namely <code>myX</code>. <s>Just as an example: in R, I would pass <code>myY</code> to <code>optim(...)</code> in the following way : <code>optim(par,fn=MyRFunction,y=myY)</code>.</s></p>
<p>Any advice on how to properly access <code>myY</code> from within the C++ function is appreciated, here's a minimal example of what I am afraid is a really wrong way to do it:</p>
<p><strong>Update</strong> : I've modified the code to better reflect the context as well as what has been proposed in the answers. Just in case, the focus of my question lies on this line : <code>NumericVector y = env["myY"]; // How to avoid this?</code></p>
<pre><code>#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export]]
double MyCppFunction(NumericVector x) {
Environment env = Environment::global_env();
NumericVector y = env["myY"]; // How to avoid this?
double res = 0;
for (int i = 0; i < x.size(); i++) res = res + (x(i) * y(i));
return res;
}
double MyCppFunctionNoExport(NumericVector x) {
Environment env = Environment::global_env();
NumericVector y = env["myY"]; // How to avoid this?
double res = 0;
for (int i = 0; i < x.size(); i++) res = res + (x(i) * y(i));
return res;
}
// [[Rcpp::export]]
double MyCppFunction2(NumericVector x, NumericVector y) {
double res = 0;
for (int i = 0; i < x.size(); i++) res = res + (x(i) * y(i));
return res;
}
// [[Rcpp::export]]
double MyRoutine(NumericVector x, Function fn) {
for (int i = 0; i < x.size(); i++) fn(x);
return 0;
}
// [[Rcpp::export]]
double MyRoutineNoExport(NumericVector x) {
for (int i = 0; i < x.size(); i++) MyCppFunctionNoExport(x);
return 0;
}
/*** R
MyRFunction <- function(x, y=myY) {
res = 0
for(i in 1:length(x)) res = res + (x[i]*y[i])
return (res)
}
callMyCppFunction2 <- function(x) {
MyCppFunction2(x, myY)
}
set.seed(123456)
myY = rnorm(1e3)

Panning in SharpGL distorts image
|
<p>I have this code in SharpGL where zoom and pan were implemented. This is de draw method:</p>
<pre><code>private void OpenGLDraw(object sender, SharpGL.WPF.OpenGLRoutedEventArgs args)
{
// Enable finish button
if (openFileOk && dispCBOk) { finish_btn.IsEnabled = true; }
else { finish_btn.IsEnabled = false; }
// Get the OpenGL object
OpenGL gl = GLControl.OpenGL;
// Set The Material Color
float[] glfMaterialColor = new float[] { 0.4f, 0.2f, 0.8f, 1.0f };
float w = (float)GLControl.ActualWidth;
float h = (float)GLControl.ActualHeight;
// Perspective projection
gl.Viewport(0, 0, (int)w, (int)h);
gl.Ortho(0, w, 0, h, -100, 100);
// Clear The Screen And The Depth Buffer
gl.Clear(OpenGL.GL_COLOR_BUFFER_BIT | OpenGL.GL_DEPTH_BUFFER_BIT);
gl.Material(OpenGL.GL_FRONT_AND_BACK, OpenGL.GL_AMBIENT_AND_DIFFUSE, glfMaterialColor);
gl.MatrixMode(MatrixMode.Modelview);
gl.LoadIdentity();
gl.Scale(scale,scale,1);
// Camera Position
gl.LookAt(_position[0], _position[1], _position[2],
_viewPoint[0], _viewPoint[1], _viewPoint[2],
_upVector[0], _upVector[1], _upVector[2]);
// Draw the helix
float[][] points = vertexes.ToArray();
Helix(points.Length, points);
}
</code></pre>
<p>What I have here is a perspective projection using Viewport (the ortho projection and scale are used for zooming).
This is the code for panning whatever is drawn on the screen:</p>
<pre><code>// pan
// y axis
// Up
if (keyCode == 1)
{
_viewPoint[1] += _moveDistance;
_position[1] += _moveDistance;
}
// Down
else if (keyCode == 2)
{
_viewPoint[1] += -_moveDistance;
_position[1] += -_moveDistance;
}
// x axis
// Left
else if (keyCode == 3)
{
_viewPoint[2] += _moveDistance;
_position[2] += _moveDistance;
}
// Right
else if (keyCode == 4)
{
_viewPoint[2] += -_moveDistance;
_position[2] += -_moveDistance;
}
</code></pre>
<p>The thing is that when I move too much to any one of the sides (up, down, left, right), the drawing gets really distorted. I didn't notice it at first because I was working with the image very zoomed in and couldn't see the difference, but now I see that the distortion always happens, it's just more intense the more you move away from the image.
All I want to know is why this happens, and if possible, a solution for it, thank you.</p>
<p>Here is an example of what happens:</p>
<p><a href="https://i.stack.imgur.com/DvmRr.png" rel="nofollow noreferrer">Normal view</a><br />
<a href="https://i.stack.imgur.com/DvmRr.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DvmRr.png" alt="" /></a></p>
<p><a href="https://i.stack.imgur.com/1PezI.png" rel="nofollow noreferrer">Distorted view</a>

Analog clock app state stopping when submitting form
|
<p>I am working on this React app to make an Analog Clock with optional Inputs available to the user to change the color of the clock hands, clock border, etc.</p>
<p>But when I try to press the submit button sometimes, the second hand stops moving all of a sudden and seems like the 'time' states are not changing. The colors however do always change as intended so color states do change.</p>
<p>I tried to incorporate preventDefault() but it's a no go...</p>
<p>The first code snippet is defining the hooks, second is the form and third is the main App js file. I didn't include the JS/CSS files that include the transform and styling info.</p>

How to make the filtering queries more efficient using flask sqlalchemy?
|
<p>I have a following table in a flask app</p>
<pre><code>class Price(db.Model):
__tablename__ = "prices"
id = db.Column(db.Integer, primary_key=True)
country_code = db.Column(db.String(2), nullable=False)

start = db.Column(db.DateTime(timezone=True), nullable=False)
end = db.Column(db.DateTime(timezone=True), nullable=False)
price_type = db.Column(db.String(32), nullable=False)

<p>The following parameters are being taken as input to the <code>get</code> method</p>
<pre><code>from flask_restx import Resource, reqparse, inputs

parser.add_argument("country_code", default=None, type=str,

def get(self):
args = parser.parse_args()
return DatabaseService.read_list(**args)
</code></pre>
<p>where <code>ns</code> is a namespace I am using</p>
<p>I am currently working on enabling filtering on the table and I have the following code:</p>
<pre><code>class DatabaseService:
@staticmethod
def read_list(**filters):
page = filters.pop('page')
limit = filters.pop('limit')
direction = filters.pop('dir')
sort = filters.pop('sort')
start_date = filters.pop('start')
end_date = filters.pop('end')
value_from = filters.pop('value_from')
value_to = filters.pop('value_to')
if all(filters[c] is not None for c in ('country_code', 'price_type')):
print('Both are not none')
items = Price.query.filter_by(**filters)
elif all(filters[c] is None for c in ('country_code', 'price_type')):
print('Both are none')
items = Price.query
elif filters['country_code'] is None:
filters.pop('country_code')
items = Price.query.filter_by(**filters)
elif filters['price_type'] is None:
filters.pop('price_type')
items = Price.query.filter_by(**filters)
</code></pre>
<p>The code shown above works perfectly fine, but I was wondering if there is more efficient way of filtering the data. For example, if there is a way to combine the last 2 <code>elif</code> statements into one and do the filtering using <code>filter_by</code> or <code>filter</code></p>
<p><strong>Sample Data</strong></p>
<pre><code>{
"items": [
{
"id": 1,
"value": 21.4,

Changing cursor when rendering a JList
|
<p>I've achieved what I'm trying to do, but I can't help but to think there is a more efficient way...allow me to illustrate.</p>
<p>In short, the question I'm asking is if there's a way to determine when a component has finished it's initial rendering.</p>
<p>I have a JList, which is hooked up to a DefaultListModel and getting painted by a custom renderer which extends the DefaultListCellRenderer.</p>
<p>This intention of the JList is to "page" through a log file, populating 2500 elements every time a new page is loaded. On my machine it usually takes a couple seconds to fully render the JList, which is not really a problem because changing the cursor to a wait cursor would be acceptable because it would give the user immediate feedback. Unfortunately, I cannot figure out an elegant way to know when the initial rendering has completed.</p>
<p>Below is the code of my renderer, in it you'll see I'm counting the number of iterations on the renderer. If that is between 0 and N-20, the cursor changes to a wait cursor. Once N-20 has been reached, it reverts back to a default cursor. Like I previously mentioned, this works just fine, but the solution really feels like a hack. I've implemented the ListDataListener of the DefaultListModel and the PropertyChangeListener of the JList, but neither produce the functionality I'm looking for.</p>
<pre><code>/**

Is there something wrong with my CMakeLists?

<p>The following is my CMakeLists file. By default, I expect it to define the symbol ALLEGRO_STATICLINK in the agui_allegro5 library, but it does not, however when I check off WANT_SHARED it defines it, which it shouldnt, but does not define AGUI_BACKEND_BUILD as it should. Is my logic flawed or something?</p>

Should I use LinearLayout or RelativeLayout to have 4 objects fill a screen?
|
<p>I am learning about the difference between <code>LinearLayout</code> and <code>RelativeLayout</code> and am confused about the best way to solve my specific problem. I want to have 4 buttons fill a screen, each with some different action. After having trouble with <code>RelativeLayout</code>, I was recommended to switch to <code>LinearLayout</code> by <a href="https://stackoverflow.com/questions/6982395/set-two-buttons-to-same-width-regardless-of-screen-size">this</a> SO thread. Using a nested <code>LinearLayout</code> and the <code>android:weight</code> value, I got a solution that does work properly. However, now I get the warning: "Nested weights are bad for performance." I propmtly looked that up on SO and found <a href="https://stackoverflow.com/questions/9430764/why-are-nested-weights-bad-for-performance-alternatives">this</a> article, telling me to switch back to <code>RelativeLayout</code>. </p>
<p>What's the right answer? Is there a good way to have objects fill an area like this in <code>RelativeLayout</code>? </p>
<p>This is my current code. Excuse the extra stuff, not sure what to leave in and what to just take out.</p>

Cross browser support for get and set properties

What is the correct foreign key constraint syntax for a database migration in Laravel 8.X Eloquent?
|
<p>I am a Laravel and Eloquent noob.</p>
<p>I'm trying to do a simple foreign key in a "checklist items" table that takes the primary ID from the "users" table as a foreign key.</p>
<p>Here are my two database migrations:</p>
<p>users:</p>
<pre><code><?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
</code></pre>
<p>items:</p>
<pre><code><?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateItemsTable extends Migration
{
/**
* Run the migrations.
*

*/
public function up()
{
Schema::create('items', function (Blueprint $table) {
$table->id();
$table->integer('user_id')->unsigned();
$table->string('itemName');
$table->string('itemDescription');
$table->timestamps();
});
Schema::table('items', function($table) {
$table->foreign('user_id')->references('id')->on('users');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('items');
}
}

<p>It should be noted that I can achieve what I need fine in the PHPMyAdmin GUI directly, or using basic PHP PDOs, but I don't understand Eloquent and need to understand what I am doing wrong.</p>
<p>I have a feeling that it's to do with a mismatch in the attribute definitions between the two table migrations, but the few things I tried caused alternate errors.</p>

<p>There are more than one Batch Report with same procedures in my project, thats why I want to use DefaultBatchReportService to handle every BatchReport by passing different class to it. (RT001..., RT002..., RT003..) Then, developers can focus on drawing the 'single' report.</p>

Show specific text from a php loop of database results using jquery
|
<p>I have selected data from my database and I have looped through the results to display them on my page. I have 3 results which are shown. Each result has a button with an id called decrease. When I click this button, an alert with the name of the item containing the alert button should be displayed. I am using jQuery to achieve this. </p>
<p>My problem is that whenever I click the button, the name of only the first item in the results array is displayed. The buttons in the other two results don't seem to work. What am I doing wrong?</p>
<p>The code that loops through the result and displays the items in the database table:</p>
<pre><code>if(mysqli_num_rows($run) >= 1){
while($row = mysqli_fetch_assoc($run)) {
$name = $row['name'];
$quantity = $row['quantity'];
$price = $row['price'];
$image = $row['image'];
$category = $row['category'];
$total = $price * $quantity;
echo "<div class=\"post-container\">\n";
echo "<div class=\"post-thumb\">\n";
echo "<img src='$image'>\n";
echo "</div>\n";
echo "<div class=\"post-title\">\n";
echo "<h4 style=\"font-weight:bold;\">\n";
echo "<a href=\"view.php?name=$name&category=$category\" class=\"links\" target=\"_blank\">$name</a>\n";
echo "<span id=\"deletion\">Delete</span>\n";
echo "</h4>\n";
echo "</div>\n";
echo "<div class=\"post-content\">\n";
echo "<ul style=\"list-style-type:none;\">\n";
echo "<li>Cost Per Item: <span id=\"cost\">$price</span>/=</li>\n";
echo "<li>\n";
echo "Quantity: \n";
echo "<button type=\"submit\" id=\"decrease\" class=\"glyphicon glyphicon-minus\" title=\"Decrease Quantity\"></button>\n";
echo "\n";
echo "<span id=\"cost\" class=\"quantity\">&nbsp$quantity&nbsp</span>\n";
echo "\n";
echo "<button type=\"submit\" id=\"increase\" class=\"glyphicon glyphicon-plus\" title=\"Increase Quantity\"></button>\n";
echo "</li>\n";
echo "<li>Total Cost: <span id=\"cost\">$total</span>/=</li>\n";
echo "</ul>\n";
echo "</div>\n";
echo "</div>";
}
}
</code></pre>
<p>And here's the jquery:</p>
<pre><code>$("#decrease").click(function(){
var name = $(this).parent("li").parent("ul").parent("div.post-content").siblings("div.post-title").find("a").text();
alert(name);
});

Could this publish / check-for-update class for a single writer + reader use memory_order_relaxed or acquire/release for efficiency?
|
<h1>Introduction</h1>
<p>I have a small class which make use of std::atomic for a lock free operation. Since this class is being called massively, it's affecting the performance and I'm having trouble.</p>
<h1>Class description</h1>
<p>The class similar to a LIFO, but once the pop() function is called, it only return the last written element of its ring-buffer (only if there are new elements since last pop()). </p>
<p>A single thread is calling push(), and another single thread is calling pop(). </p>
<h1>Source I've read</h1>
<p>Since this is using too much time of my computer time, I decided to study a bit further the std::atomic class and its memory_order. I've read a lot of memory_order post avaliable in StackOverflow and other sources and books, but I'm not able to get a clear idea about the different modes. Specially, I'm struggling between acquire and release modes: I fail too see why they are different to memory_order_seq_cst.</p>
<h1>What I <strong>think</strong> each memory order do using my words, from my own research</h1>
<p><strong>memory_order_relaxed:</strong> In the same thread, the atomic operations are instant, but other threads may fail to see the lastest values instantly, they will need some time until they are updated. The code can be re-ordered freely by the compiler or OS.</p>
<p><strong>memory_order_acquire / release:</strong> Used by atomic::load. It prevents the lines of code there are before this from being reordered (the compiler/OS may reorder after this line all it want), and reads the lastest value that was stored on this atomic using <strong>memory_order_release</strong> or <strong>memory_order_seq_cst</strong> in this thread or another thread. <strong>memory_order_release</strong> also prevents that code after it may be reordered. So, in an acquire/release, all the code between both can be shuffled by the OS. I'm not sure if that's between same thread, or different threads. </p>
<p><strong>memory_order_seq_cst:</strong> Easiest to use because it's like the natural writting we are used with variables, instantly refreshing the values of other threads load functions.</p>
<h1>The LockFreeEx class</h1>
<pre class="lang-cpp prettyprint-override"><code>template<typename T>
class LockFreeEx
{
public:
void push(const T& element)
{
const int wPos = m_position.load(std::memory_order_seq_cst);
const int nextPos = getNextPos(wPos);
m_buffer[nextPos] = element;
m_position.store(nextPos, std::memory_order_seq_cst);
}
const bool pop(T& returnedElement)
{
const int wPos = m_position.exchange(-1, std::memory_order_seq_cst);
if (wPos != -1)
{
returnedElement = m_buffer[wPos];
return true;
}
else
{
return false;
}
}
private:
static constexpr int maxElements = 8;
static constexpr int getNextPos(int pos) noexcept {return (++pos == maxElements)? 0 : pos;}
std::array<T, maxElements> m_buffer;
std::atomic<int> m_position {-1};
};
</code></pre>
<h1>How I expect it could be improved</h1>
<p>So, my first idea was using memory_order_relaxed in all atomic operations, since the pop() thread is in a loop looking for avaliable updates in pop function each 10-15 ms, then it's allowed to fail in the firsts pop() functions to realize later that there is a new update. It's only a bunch of milliseconds.</p>
<p>Another option would be using release/acquire - but I'm not sure about them. Using release in <strong>all</strong> store() and acquire in <strong>all</strong> load() functions.</p>
<p>Unfortunately, <em>all the memory_order I described seems to work</em>, and I'm not sure when will they fail, if they are supposed to fail.</p>
<h1>Final</h1>
<p>Please, could you tell me if you see some problem using relaxed memory order here? Or should I use release/acquire (maybe a further explanation on these could help me)? why?</p>
<p>I think that <em>relaxed</em> is the best for this class, in all its store() or load(). But I'm not sure!</p>
<p>Thanks for reading.</p>
<h1>EDIT: EXTRA EXPLANATION:</h1>
<p>Since I see everyone is asking for the 'char', I've changed it to int, problem solved! But it doesn't it the one I want to solve. </p>
<p>The class, as I stated before, is something likely to a LIFO but where only matters the last element pushed, if there is any.</p>
<p>I have a big struct T (copiable and asignable), that I must share between two threads in a lock-free way. So, the only way I know to do it is using a circular buffer that writes the last known value for T, and a atomic which know the index of the last value written. When there isn't any, the index would be -1.</p>
<p>Notice that my push thread must know when there is a "new T" avaliable, that's why pop() returns a bool.</p>
<p>Thanks again to everyone trying to assist me with memory orders! :)</p>
<h1>AFTER READING SOLUTIONS:</h1>
<pre><code>template<typename T>

Cant display values from a bean method into <table>

<p>I have this problem. i implemented this table in my xhtml:</p>
<pre><code> <table id="tbResult" class="table table-bordered table-striped">
<thead>

<th>#{msg.Sgc001tbcod}</th>
<th>Browser</th>
</tr>

<p>And this select on my BEAN:</p>
<pre><code>public void select(int first, int pageSize, String sortField, Object filterValue) throws SQLException, ClassNotFoundException, NamingException {
//System.out.println("entre al metodo SELECT");

How to add empty value from gridview cell to list?
|
<p>I want to enter guest details(Title,Firstname,midname lastname) in a <code>list<string></code> ,the guest details can be empty.I'm using LINQ for inserting in the list.I had referred this question for the LINQ code <a href="https://stackoverflow.com/questions/21314109/datagridview-write-all-values-from-a-column-to-list">DataGridView write all values from a column to list</a></p>
<p>All I want to do is enter the text into the list if it has or insert empty string if it doesn't have.Right now if I leave textboxes blank it will throw <code>object reference not set to instance of an object exception</code></p>
<pre><code>private string SaveGuestDetails()
{
string strRet = string.Empty;
Reservation obj = new Reservation();
FinalReservationDetails f = new FinalReservationDetails();
try

C Pthread taking much longer than single threaded

<p>I've made a matrix multiplier piece of code designed to quantify how much faster threading is for each size of matrix. The code where threads are made and executed is below. I'm new to threading but whenever I use threading it seems to take about 12 times longer, am I doing something wrong or does anyone know why it's so much slower?</p>

EJB, JPA/Hibernate. I cannot make an insert in a database
|
<p>I am using Glassfish, EJB, JPA and Hibernate as a JPA implementation. I can get a select from a database via JPA but an insert does not work. Looks like a problem with JTA(may be a transaction was not completed or I use an another transaction) Persistence content does not flush to a database. The same code works properly when I use eclipselink as JPA implementation but I have to use hibernate.</p>
<pre>
<code>
@Stateless
@LocalBean
public class BeanISManagedByContainer
{
@PersistenceContext(unitName = "com.company_JPATest2-ejb_ejb_1.0PU")
EntityManager entityManager;
public String getMessage(int id)
{
return entityManager.find(Message.class, id).getText();
}
public void addMessaage(String txt)
{
Message message = new Message();
message.setText(txt);
entityManager.persist(message);
}
}
</code>
</pre>
<p>getMessage() method is works properly, but addMessaage() does not insert any data to a database and there are not any logs. Persistence context was not flushed to a database. I have tried to manage a transaction manually but the same result. I do not know what is wrong with a hibernate configuration. Please advise.</p>
<pre>
<code>
@Stateless
@LocalBean
@TransactionManagement(TransactionManagementType.BEAN)
public class ManualTransactions
{
@PersistenceContext(unitName = "com.company_JPATest2-ejb_ejb_1.0PU")

@Resource
private UserTransaction transaction;
public void addMessaage(String txt) throws Exception
{
Message message = new Message();
message.setText(txt);
transaction.begin();
Logger.getLogger(ManualTransactions.class.getName())
.info("transaction status: " + transaction.getStatus());
entityManager.persist(message);
Logger.getLogger(ManualTransactions.class.getName())
.info("transaction status: " + transaction.getStatus());

Creating user accounts for pre-registered users in Django
|
<p>I have a website that has a registration system and a blog with some registered users. Yesterday, I added a new app that creates dedicated profile pages for each one of those users. </p>
<p>The issue being, the profile pages aren't getting created for the users that have already registered. This is, I guess because the user profile creation logic allows for profile creations only after the user has registered.</p>
<p>Below is the code in my <strong><em>models.py</em></strong></p>
<pre><code>from django.db.models.signals import post_save
from django.dispatch import receiver
@receiver(post_save, sender=User)
def create_account(sender, instance, created, *args, **kwargs):
if created:
profile, new = UserAccount.objects.get_or_create(user=instance)
post_save.connect(create_account, sender=settings.AUTH_USER_MODEL)
</code></pre>
<p>So, what can I do to create those profile pages?</p>
<p>I tried the following:<br>
1. Manually creating a profile page against each registered users' username. (But this isn't the way I want to lean on. This is just a temporary arrangement)</p>
<p>Issue with this, when the superuser who creates these profile pages calls for his private profile page [at /u/], the code looks towards all the users created by the superuser instead of his own. </p>
<p>This is the error that's shown:</p>
<pre><code>MultipleObjectsReturned at /u/
get() returned more than one UserAccount -- it returned 2!
.
.
.
instance = get_object_or_404(UserAccount)
</code></pre>
<p>So, what's the issue in code here? [my views.py]</p>
<pre><code># public user profile

Adding TextView into another layout programatically
|
<p>I am strugling with one problem. I have got one main view with two layouts inside it:</p>
<pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".TestMainActivity" >
<HorizontalScrollView
android:id="@+id/menuView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal" >
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add2" />
</LinearLayout>
</HorizontalScrollView>
<com.test.board.Board
android:id="@+id/boardView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/menuView"
android:layout_centerHorizontal="true"
android:layout_marginTop="30dp" />
</RelativeLayout>
</code></pre>
<p>Board layout is my class which is inhariting from ViewGroup. What I want to achive is to add TextView (or any other Layout elent like Image, button, another layout) into my canvas (borad).</p>
<p>This is how am I doing it now:</p>
<pre><code>Button textBold = (Button) findViewById(R.id.button1);
textBold.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
TextView txt1 = new TextView(TestMainActivity.this);
txt1.setText("Sample text");
txt1.setTextColor(Color.BLUE);
txt1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
myView.addView(txt1);
}
});
</code></pre>
<p>myView is object of class Board.</p>
<p>When I am checking the number of child elements is increasing each time, but I don't see this TextView.</p>
<p>Can someone please tell me, what I have to do to make this text visible?</p>
<p><strong>EDIT</strong></p>
<p>It might be a mistake that I didn't put whole onCreat method, where I initialize myView. So there it is:</p>
<pre><code>protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myView = (Board) findViewById(R.id.boardView1);
myView.setBackgroundColor(Color.WHITE);
myView.refreshView(); //function below
Button textBold = (Button) findViewById(R.id.button1);
textBold.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
TextView txt1 = new TextView(TestMainActivity.this);
txt1.setText("Sample text");
txt1.setTextColor(Color.BLUE);
txt1.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
myView.addView(txt1);
}
});
</code></pre>
<p>there is refreshView() function just for extra:</p>
<pre><code>public void refreshView() {
// redraw the view
invalidate();
requestLayout();
}
</code></pre>

vba - saving file to my personal desktop code
|
<p>I have the following code which is designed so I can quick save to my desktop and then put the file into a folder. This code works fine if the file is already saved in an .xls, .csv, .xlsx or .xlsm file extension, however, when the file IS NOT saved, I only get the pop-up message boxes, and nothing happens. I was thinking about re-structuring using a CASE STATEMENT with right(activeworkbook.name, 4), but didn't know how to structure as I am not familiar with these statements. Thank you.</p>

Problems building a flooding script that uses sockets

<p>I'm trying to improve 2 projects of flooders (not mine) making my own script that these 2 ones. Doing that, I've almost finished but I'm stuck in a point where the script does nothing.

<p>As you can see, this script uses a list of proxies to send request (using socket library) to target. But when I arrive at "Enter the proxy list" and after typed "proxy.txt", the script gets stuck! What did I do wrong? Can you help me?</p>

Floating div's left or right depending on variable WITHOUT columns
|
<p>I'm modifying my current build of one of my pages where there are X amount of boxes with varying content in each box, some float to the left, some float to the right and some fill the whole column space. The way this is currently done is like this:</p>
<p><strong>HTML</strong></p>
<pre><code><div class="doubleColumn">
<div class="contentBox"></div>
<div class="contentBox"></div>
<div class="singleColumn left">
<div class="contentBox"></div>
</div>
<div class="singleColumn right">
<div class="contentBox"></div>
</div>
</div>
</code></pre>
<p><strong>CSS</strong></p>
<pre><code>.doubleColumn {
float: left;
width: 100%;
}
.singleColumn {
width: 49%;
}
.contentBox {
border: 1px solid RGB(0, 0, 0);
box-sizing: border-box;
-moz-box-sizing: border-box;
margin-bottom: 20px;
padding: 10px;
width: 100%;
}
.left {
float: left;
}
.right {
float: right;
}
</code></pre>
<p>For the current solution there is no issues as the layout works perfectly and if below the left and right columns i wanted to add another 2 wider content boxes, i simply add those, then perhaps another 2 inside a left column below that. The issue comes when i try to assign variables to determine which box goes where, because i'm trying to make it so we can adjust each box to be either at the top, bottom or middle or wherever else we wish it to be, and also adjust whether it sits on the left, right or fills the whole box. I got a "half-working" solution in which i use the to run a check that if a boxes position equals one, it fills the space, if it equals 2 it floats left and if it equals 3 it floats right. I'll demonstrate once again below:</p>
<p><strong>HTML</strong></p>
<pre><code><cfquery datasource="datasource" name="boxes">
Select *
From boxes
Order by box_order
</cfquery>
<div class="doubleColumn">
<cfoutput query="boxes">
<cfif box_position eq 1>
<div class="contentBox"></div>
<cfelseif box_position eq 2>
<div style="clear: left; float: left; width: 49%;">
<div class="contentBox"></div>
</div>
<cfelseif box_position eq 3>
<div style="clear: right; float: right; width: 49%;">
<div class="contentBox"></div>
</div>
</cfif>
</cfoutput>
</div>
</code></pre>
<p>But if I have two in a row that float left, then one that float right it (as it would) floats next to the second one on the left rather than the first one because of using clear, but if i don't use clear then the second left will sit alongside the first left. I'm stuck and don't know how to solve this issue.</p>

how to programmatically show a colored disk behind a UIImageView, in swift on an iOS device

National Communications Director Alex Brynner said the Trump administration needs to help then-Secretary of State Rex Tillerson learn from him.
"The Cabinet, like any other government job, has to be attentive to the needs of an individual that might challenge his or her position," Brynner said. "This is especially true in times of renewed volatility."
Brynner said Tillerson has not "failed at vetting

<p>There are slight delays during video recording, because I print information from sensors on video, can this affect the concatenation of video with audio? (Saved video is accelerated? that's why at the beginning I used slowing video down.)</p>

How to create a “sessionId” column using timestamps and userid in PySpark?
|
<p>I have a data set which contains fields such as: userId, event, pageName, and timestamp, while lacking of the sessionId. I want to create a sessionId for each record based on the timestamp and a pre-defined value "finish" (which indicates after how many minutes of inactivity a session ends). Only users with the same UserId can be in the same session.</p>
<p>If the "finish" value is 30 minutes (1800 difference in timestamp), and a sample DataFrame is:</p>
<pre><code>from pyspark.sql import functions as F
from pyspark.sql.window import Window
df = spark.createDataFrame([
("blue", "view", 1610494094750, 11),
("green", "add to bag", 1510593114350, 21),
("red", "close", 1610493115350, 41),
("blue", "view", 1610494094350, 11),
("blue", "close", 1510593114312, 21),
("red", "view", 1610493114350, 41),
("red", "view", 1610593114350, 41),
("green", "purchase", 1610494094350, 31)
], ["item", "event", "timestamp", "userId"])

|green| purchase|1610494094350| 31|
+-----+----------+-------------+------+

<p>The end result should be something like this:</p>
<pre><code>+--------+----------+-------------+------+---------+

How can I get the current value from a variable when passing it to an event?
|
<p>I have the following problem. I'm making an ajax request to an API which returns a <strong>json</strong>. I iterate through the json object and list the results in li tags the tricky part comes here when I make the <em>li.OnClick()</em> event I need to pass the current index of the selected item but i always get the last one. I think it's because it is passed by reference not by value. How can I cope with this problem?</p>

Why does interp1d throw LinAlgError("SVD did not converge")?
|
<p>I have a sequence of 2 dimensional points (so: (x,y) coordinates) and I want to fit a cubic spline through it. So I split the sequence in two sequences <code>xs</code>, <code>ys</code> with the following properties:</p>
<ul>
<li><code>len(xs) = len(ys) > 4</code></li>
<li><code>xs</code> is strictly increasing</li>
</ul>
<p>So there should be a cubic spline through those points. But I still get an error:</p>

Put Json/Jsonp data to a form using ajax
|
<p>The chinese map service "Tencent map" provides a Json/Jsonp URL to get the location information, the URL is like:</p>
<p><a href="http://apis.map.qq.com/ws/geocoder/v1/?location=39.984154,116.307490&key=OB4BZ-D4W3U-B7VVO-4PJWW-6TKDJ-WPB77&get_poi=1" rel="nofollow">http://apis.map.qq.com/ws/geocoder/v1/?location=39.984154,116.307490&key=OB4BZ-D4W3U-B7VVO-4PJWW-6TKDJ-WPB77&get_poi=1</a></p>
<p>Assume that I fill the latitude and longitude into a form, how to use JS/JQ to get the Json date and fill the "pois"(which in the json-> result -> pois ) data to a drop-down menu in the form?</p>
<p>The html I wrote is like:</p>
<pre><code><from>
<lable>Oraginal GPS coordinates</lable></br>
<input type="text" id="geo_latitude" name="geo_latitude" value="39.86343486063931">
<input type="text" id="geo_longitude" name="geo_longitude" value="116.37321682380312">
<button onclick="getLocation()">GET it</button>
<select id="geo_spot" name="geo_spot">
<option></option>
</select>
</form>
</code></pre>
<p>The Js is:(to make it jsonp I added "?output=jsonp" in the url to make it Jsonp to avoid Cross domain error)</p>
<pre><code> jQuery(document).ready(function(){
var lat = parseFloat(document.getElementById("geo_latitude").value);
var lng = parseFloat(document.getElementById("geo_longitude").value);
var url='http://apis.map.qq.com/ws/geocoder/v1/?output=jsonp&location='+lat+','+lng+'&key=OB4BZ-D4W3U-B7VVO-4PJWW-6TKDJ-WPB77&get_poi=1&callback=?';
jQuery.ajax({
url:url,
dataType:'jsonp',
processData: true,
type:'get',
jsonp: "callback",
contentType: "application/jsonp; charset=utf-8",
success:function(data){
alert(jsonp.result.pois);
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
alert(textStatus);
}});
});
</code></pre>
<p>My target is to add up all Pois date in Jsonp into that drop down options, but after tried and tried, I can't even get the date....</p>
<p>Can you point out the mistake of my code? That would be very helpful!</p>
<p>I put a sample here so you can test my MISTAKE <a href="http://fireso.com/geo.html" rel="nofollow">http://fireso.com/geo.html</a> </p>
<p>PS, I can't modify the server part code, and have to use the api in a different domain, so the only way is working with the html js part.</p>
<p>Thank you for any help!</p>

Unable to implement CustomAuthenticationProvider with Spring Security: BeanCreationException while autowiring
|
<p>I am implementing CustomAuthenticationProvider in Spring Security. I have created the CustomAuthenticationProvider class which implements AuthenticationProvider. However, when I define this CustomAuthenticationProvider in my SecurityConfiguration class and autowire it, the application throws following error:</p>
<pre><code>2020-03-08 19:27:42 [main] ERROR o.s.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.highrise.isimwebapp.config.customauth.CustomAuthenticationProvider com.highrise.isimwebapp.config.SecurityConfiguration.authProvider; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.highrise.isimwebapp.config.customauth.CustomAuthenticationProvider] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
</code></pre>
<p>I have included the @Component annotation in my CustomAuthenticationProvider class. Also, the package under which this class is defined, is included in the @ComponentScan. The context is not picking up CustomAuthenticationProvider bean. The other defined classes are successfully getting picked up by the context as defined in the @ComponentScan and no such error is received on their autowired objects. What could be wrong from my side? Any help regarding how this can be fixed would be highly appreciated.</p>

React and Axios Post payload formatting
|
<p>I'm really new to this so forgive me if I word things wrong.
So right now I have a simple web UI with a text box for a Name, and then a checkmark selection box for a type, along with a submit button.</p>
<p>Test code looks something like this:</p>
<pre><code>value = "val7";
key = "63";
typeID = 103;
name = "testname";
const onSubmitClick = (event) => {
axiosPost('testurl',
{
Message: {
Type: typeID,
Payload: {
title: null,
messagebody: null,
data: {
value,
key,
},
},
Delivery: {
Name: [{"Name": name}]
}
}
})
}
</code></pre>
<p>and when I press submit, the Payload looks like this:</p>
<pre><code>{
"Message": {
"Type": 103,
"Payload": {
"title": null,
"messagebody": null,
"data": {
"value": "val17",
"key": "63"
}
},
"Delivery": {
"Name": [{
"Name": "testname"
}]
}
}
}
</code></pre>
<p>However, I need the data portion of the payload to look more like this:</p>
<pre><code>{
"Message": {
"Type": 103,
"Payload": {
"title": null,
"messagebody": null,
"data": {
"val17": "63"
}
},
"Delivery": {
"Name": [{
"Name": "testname"
}]
}
}
}
</code></pre>
<p>How do I go about doing this?</p>

Fading element in the center of window by scrolling
|
<p>I use a script in which elements fade in from the left and right as soon as the respective element has been scrolled completely into view. The problem is, the fade-in remains until the element has completely disappeared from the field of view. I try to implement it in such a way that it fades out as soon as it is no longer completely in sight. Otherwise, all elements are shown at the same time when scrolling.</p>

Swift - Visual format language - how to make multiple rows and columns
|
<p>I just started swift programming and i'm facing difficulties with visual format constraints. I'm trying to make multiple tables of 3 by 6 rows and columns with and header on top of the table. I have added the names of the row and columns but it's not aligned in the expected (by me) order. The problem in below code is: the line</p>
<pre><code>> addConstraintsWithFormat(format: "H:|-40-[v0][v1][v2]-[v3]-[v4]-|",
> views: cashLabel, pinLabel, idealLabel, houseLabel,
> totalPerPayMethodLabel) is placed in between the rows of
> addConstraintsWithFormat(format: "V:|-[v0(30)]-[v1]-[v2]-[v3]-|",
> views: timePeriodLabel, highBtwLabel, lowBtwLabel, totalPerBtwLabel).
</code></pre>
<p>Also the cashLabel has a big gap with the pinLabel. When i remove the (30) from view v0 the line with the cashLabel, pinLabel etc. is placed above the other rows (V:) as expected. Also the cashLabel does not seem to be affected by the H:-40-[v0] etc.</p>

Microsoft Chart size varies on different build server despite defining the fixed height and width
|
<p>I have a problem where I am rendering MS Chart on Pdf on Active Report 6 (Picture control) through memory stream. I have encountered a problem where the size of my chart is varying based on the build server. Not sure which property is causing this issue.
On few build machine the Chart is huge and on few the chart size is reduced.</p>
<p>Any pointer ??</p>
<p>I have a scheduler service built on DotNet framework 3.5 running on my local machine Windows 10.
MS chart version being used - 3.5 Framework
Active Reports - version 6</p>
<p>Where as when actually the service being delivered to QA which is Windows server 2016, the size of chart is being changed .</p>
<p>Below is the code</p>
<p>//*********Chart defining</p>
<pre><code> Chart chart = new Chart();
chart.Height = 100;

Make my MySQL query less verbose
|
<p>The following query was a real challenge for me to build for a Wordpress site using the wordpress wp_post table and the wp_postmeta table and the wp_user table. It works perfectly but it contains a lot of repeated statements. I am not sure how to simplify this (or if it can be). Any tips for simplifying and ridding the repetition would be appreciated.</p>
<p>The tables contain data like this:</p>

How to use spring mvc with thymeleaf to iterate over a list?
|
<p><em>My goal is to cycle through a list of objects, some to be displayed on the screen, others to be passed into a form as an object of which I can define certain aspects and then return to the controller the object and attribute to be modified.</em></p>
<p><em>The problem with the following approach is that the object in the list is not passed correctly to the form and thus gives an error because it is trying to make changes to a non-existent object.</em></p>
<p>If, on the other hand, I try to pass it as an object via ModelAndView it obviously works but does not have all the characteristics of the object I passed via the list.</p>
<p><strong>Controller</strong></p>
<pre><code>@GetMapping("/")
public ModelAndView home() throws IOException {
ModelAndView mv = new ModelAndView();
mv.setViewName("home");
List<Comics> allComics = cs.getAll();
mv.addObject("comics", allComics);
return mv;
}
@PostMapping("/update")
public ModelAndView update(Comics com, @RequestParam("attr") String attr) throws IOException {
ModelAndView mv = new ModelAndView();
com.setLastRead(attr);
cs.updateAttributes(com);
mv.setViewName("home");
List<Comics> allComics = cs.getAll();
mv.addObject("comics", allComics);
return mv;
}
</code></pre>
<p><strong>home.html</strong></p>
<pre><code><html xmlns:th="http://www.thymeleaf.org">
<tr th:each="comic : ${comics}">
<td th:text="${comic.title}"></td>
<td th:text="${comic.lastChapter}"></td>
<td>
<a th:href="${comic.lastChapterLink}" target="_blank"
role="button" class="btn btn-md btn-block btn-info"> Link
</a>
</td>
<td></td>
<td>
<form th:action="@{/update}" th:object="${comic}" method="post">
<input type="text" name="attr" id="attr"/>
<button type="submit">Sub</button>
</form>
</td>
</tr>
</code></pre>
<p>PS: I cut out the head of the html page because it was full of non-relevant CDNs</p>
<p><em>How can I integrate Spring MVC with Thymeleaf to achieve the result whereby passing a list of objects can be displayed on the screen and used for other purposes within the html page without throwing errors?</em></p>
<p>Obviously if you know of more efficient methods to achieve the result I'm listening; I only used this method because I didn't know of any others.</p>
<p>Thank you</p>
<p><strong>Answer to @RafaeldaSilva:</strong></p>
<p>I agree, but that does not solve the problem.
Let me explain: the attribute I am going to modify through the form already has its name to allow what you wrote.
But the object iterated through:</p>
<pre><code>tr th:each="comic : ${comics}">
</code></pre>
<p>cannot be passed directly as input, as it is a value that is taken from a list and exists individually only in the html page.
One might think of passing it as hidden input, but in this case the result would be the same (I have tried):</p>
<pre><code><form th:action="@{/update}" th:object="${comic}" method="post">
<input type="hidden" value="${comic}" name="com"/>
<input type="text" name="attr" id="attr"/>
<button type="submit">Sub</button>
</form>
@PostMapping("/update")
public ModelAndView update(@RequestParam("com") Comics com, @RequestParam("attr") String attr) throws IOException {
ModelAndView mv = new ModelAndView();
com.setLastRead(attr);
System.out.println("Comic: " + com);
cs.updateAttributes(com);
mv.setViewName("home");
List<Comics> allComics = cs.getAll();
mv.addObject("comics", allComics);
return mv;
}
</code></pre>
<p><strong>Error:</strong>
[org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter 'com' for method parameter type Comics is present but converted to null]</p>

Python3: GUI later cannot display output properly?
|
<p>I'm designing a GUI application that converts between celsius and fahrenheit. For now, there're primarily two problems that I'm not able to tackle:</p>
<p><strong>1)</strong> When I enter an integer that needs to be converted based on the given conversion formula, the Label from <code>tkinter</code> cannot display the output properly. In fact, it shows something like this: </p>
<pre><code><conversionModel.Conversion object at 0x1057b11d0>
</code></pre>
<p>which made it really difficult for debug to a beginner like me.</p>
<p><strong>2)</strong> There's a <code>quitButton</code>, thought which we can <code>destroy()</code> the GUI application. The problem is that when I close the GUI by clicking the red cross of the window, the Shell says: </p>
<p><code>_tkinter.TclError: can't invoke "destroy" command: application has been destroyed</code></p>
<p>I checked answers to other questions regarding the same problem, it turned out that it was because this GUI application was destroyed before closing. I had no idea how to address this particular problem.</p>
<p>Below are three pieces of code written in Model/View/Controller form:</p>
<p><strong>The Model in conversionModel.py:</strong></p>
<pre><code>class Conversion:
"""
class Conversion is the Model for a celsius-fahrenheit conversion
application. It converts celsius into fahrenheit and fahrenheit into
celsius.
"""
def toCelsius(self, temp):
return (5 / 9) * (temp - 32)
def toFahrenheit(self, temp):
return ((9 / 5) * temp) + 32
</code></pre>
<p><strong>The View in conversionView.py:</strong></p>
<pre><code>import tkinter
class MyFrame(tkinter.Frame):
def __init__(self, controller):
tkinter.Frame.__init__(self)
self.pack()
self.controller = controller
self.tempEntry = tkinter.Entry()
self.tempEntry.insert(0, "0")
self.tempEntry.pack({"side": "left"})
self.celsiusButton = tkinter.Button(self)
self.celsiusButton["text"] = "Celsius"

self.quitButton = tkinter.Button(self)
self.quitButton["text"] = "Quit"
self.quitButton["command"] = self.quit
self.quitButton.pack({"side": "left"})
</code></pre>
<p><strong>The Controller in controller.py:</strong></p>
<pre><code>import tkinter
import conversionView
import conversionModel
class Controller:
def __init__(self):
root = tkinter.Tk()
self.model = conversionModel.Conversion()
self.view = conversionView.MyFrame(self)

self.view.mainloop()
root.destroy()
def buttonToC(self):

def buttonToF(self):

self.view.labelForOutput["text"] = str(self.model) + " °F"
if __name__ == "__main__":

How do I make a box that i can move. I am new to wxwidgets and wondering if there is a way to move a box
|
<p>The Image is what I currently have made, I plan to make an Elevator that can go up and down. I am unsure of how I would move a box such that it stays at the same x cords but changes the y cords. Any help is appreciated.</p>
<p>This is for a project I am doing. The specifications state</p>
<pre><code> "In this project, the group is required to
develop a programme that simulates the operation of arrays (columns) of elevators
running over a multi‐storey building. The program (application) should be able to cope
with user defined number of elevators and number of storeys along with an ability for a
user to simulate or represent elevator passengers making request for elevator service to
particular floors. The program should have a user interface that displays the elevators’
states allows user input and ideally shows (simulates) the vertical movement of each
elevator. "
</code></pre>
<p><a href="https://i.stack.imgur.com/rnte7.png" rel="nofollow noreferrer">Simulation Plane</a></p>
<p>I am looking for something that will move the "Elevator A" box with the buttons up or down, along with a box inside the elevator shaft, both move up and down in unison. The code should do this automatically hopefully without having to drag the boxes and buttons with a mouse.</p>

How to setup CMake to build code which contains path-includes like #include <libdir/lib>?
|
<p>I am trying to migrate an old C/C++ sunstudio project to visual studio 2019. I need to build targets on a remote linux machine, so I cannot use the visual studio solution to build. After some unsuccessful attempts to use the old sunstudio makefiles, I have decided to use <strong>cmake</strong> to build the project.</p>
<p>The problem is that the code references includes with relative paths, like this:</p>
<pre><code>(tkamain.cxx):
#include <ukernel/inc/U.h>
#include <monitor/inc/monitor.h>
</code></pre>
<p>I don't want to touch the code, so how can I setup CMake to build this project properly with these specific include statements?</p>
<p>The project structure looks like this.</p>
<pre><code>tka
|-mod
||-monitor
||'-inc
||-feedutils
||'-inc
|'-ukernel
| '-inc
|-inc
||-foo.hxx
|'-bar.hxx
|-src
||-foo.cxx
||-bar.cxx
||-tkamain.cxx
|'-CMakeLists.txt (CMakeB)
'-CMakeLists.txt (CMakeA)
</code></pre>
<p>The CMakeLists.txt are newly created by me and are probably not correctly set up yet.</p>
<p>The CMakeA file contains this:</p>
<pre><code>project(tka)
add_subdirectory(src)
</code></pre>
<p>The CMakeB file contains this:</p>
<pre><code>include_directories(${PROJECT_SOURCE_DIR}/inc)
include_directories(${PROJECT_SOURCE_DIR}/mod)
add_executable(tkamain tkamain.cxx)
</code></pre>
<p>The commands in CMakeB seem not to be sufficient for my purposes, what am I missing? Or do I need more CMakeLists.txt files? </p>
<p>The errors I am getting look like this:</p>
<pre><code>[ 50%] Building CXX object src/CMakeFiles/tkamain.dir/tkamain.cxx.o

finding next/previous tv show from MySQL database
|
<p>I've become rather stuck with a situation I have. I have a database with fields id, showid, season, episode and some other arbitrary data. I have a php page to display information about episodes of shows which works by having the id as a get variable. What I wish to achieve is to have a link to the next episode and previous episode of this tv program however the shows aren't necessarily in order and so simply incrementing or decrementing the id will not help.
So I would fetch the episodes and store then in <code>$rows</code> with the following <code>MySQL</code> query:</p>
<p><code>SELECT id FROM episodes WHERE showid = $id ORDER BY season, episode;</code></p>
<p>Now without having to loop through the array (which could be rather large for some shows) is there an easy way for me to find the next and previous episode? I'm sure there is I just can't think of it.</p>
<p><strong>Edit:</strong>
I have been thinking about this myself and nothing all that helpful has come through yet (although thanks for the help, its much appreciated). What I have thought of is to make a query to see if a higher episode exists of the same season, if not make another query to find the lowest episode of then next lowest season - or something along those lines - and then repeat for previous. What do you think?</p>
<p><strong>Edit 2:</strong>
I thought I would post my final code for future reference.
Here I find the id's of the nex and previous shows (if they exist).</p>
<p>Find the next episode:</p>
<pre><code>try {
// First check for a show of the same season but the next lowest episode number
$stmt = $dbh->prepare("SELECT id FROM episodes WHERE showid = :show AND season = :s AND episode > :e ORDER BY episode LIMIT 1;");
$stmt->execute($pars);
$rows = $stmt->fetchAll();
if(count($rows) > 0) { // If there is one this is our next id
$nextid = $rows[0]['id'];
} else {
// Otherwise check for an episode of a higher season number
$stmt = $dbh->prepare("SELECT id FROM episodes WHERE showid = :show AND season > :s ORDER BY season, episode LIMIT 1;");
$stmt->execute($pars);
$rows = $stmt->fetchAll();
if(count($rows) > 0) { // If there is one this is our next id.
$nextid = $rows[0]['id'];
} // Otherwise no next id is set and so no next link will be created.
}
} catch(PDOException $e) {
die("Error: " . $e->getMessage());
}
</code></pre>
<p>Find the previous episode:</p>
<pre><code>try {
// First check for an episode in same season of the next highest episode number.
$stmt = $dbh->prepare("SELECT id FROM episodes WHERE showid = :show AND season = :s AND episode < :e ORDER BY episode DESC LIMIT 1;");
$stmt->execute($pars);
$rows = $stmt->fetchAll();
if(count($rows) > 0) { // If one is found then this is our prev id.
$previd = $rows[0]['id'];
} else {
// Otherwise check for an episode of a lower season number.
$stmt = $dbh->prepare("SELECT id FROM episodes WHERE showid = :show AND season < :s ORDER BY season DESC, episode DESC LIMIT 1;");
$stmt->execute($pars);
$rows = $stmt->fetchAll();
if(count($rows) > 0) { // If there is one this is our prev id.
$previd = $rows[0]['id'];
} // Otherwise no prev id is set and so no prev link will be created.
}
} catch(PDOException $e) {
die("Error: " . $e->getMessage());
}
</code></pre>
<p>Then I have the following links:</p>
<pre><code>if($previd) echo "<a href=\"/tv/view/" . $previd . "/\">Previous Episode</a>";
if($nextid) echo "<a href=\"/tv/view/" . $nextid . "/\">Next Episode</a>";
</code></pre>

Struts2 Dispatcher FilterMapping Cannot be Found
|
<p>I'm using the Tuckey URL re-write filter which works fine. However I'm trying to use Struts2 to implement a login system for my web app. So far I've been able to bypass my other service calls so they pass through struts (they are webservlets and I don't want to use struts for them). I can hit them, however I can't access my Login.jsp. I've tried all kinds of mixing and matching with no luck. Ultimately I want to be able to use my existing webservlets but route the user to the login page if there is not a valid session and not allow access to two pages if the user hasn't logged in. But right now I'm just trying to get the login screen to show up. I get them both working separately but can't messh them to work together.</p>
<p>Any idea on how to make the login page show up?</p>

Why doesn't nth:child work on my site when it worked on my boilerplate?
|
<p>I'm a web development student and I'm trying to use nth:child in order to code a section of a site that has images on the left and text on the right, and then the next section has text on the left and images on the right etc. Maybe it's a really simple mistake but I'm not sure why it's not working because my boilerplate worked. I'm new to stackoverflow so I'm not really sure how to format a post, so the CSS is under the HTML. I appreciate the help, thanks.</p>

Updating notifications after being added
|
<p>I want to update the content for a reminder after it has been added before being received by the user. After setting a reminder through AlarmManager using the data stored in sqlite database, the notification from the reminder set only shows the data, title and description, that was first added, not any updated data stored corresponding to the ID as primary key.</p>
<p>Things I have tried:</p>
<ul>
<li>cancelling the pending intent for the reminder then setting it again after updating the data stored in the database but it still displays the same result.</li>
<li>using an activity for adding data to be stored in the database to set a reminder and using another activity for updating this data as an attempt to update the reminder content with the same ID issued. One result shows two notifications received, one with initial title and description, and the other with updated information.</li>
</ul>
<p>Currently, the methods I use to set and cancel a reminder is in my Adapter class for Recyclerview. I am stuck on updating although adding and cancel works fine.</p>
<p>Update: Now I use two separate activities for the add and update reminder functions.</p>
<p>For adding a reminder:</p>
<pre><code>databaseManager.addReminder(titlePicked, descriptionPicked, timePicked, datePicked, dateTimePicked);
startActivity(new Intent(getApplicationContext(), MainActivity.class));
setAlarm();
private void setAlarm() {
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), ReminderReceiver.class);
intent.putExtra("DateTime", dateTimePicked);
intent.putExtra("NotifID", remId);
intent.putExtra("Title", titlePicked);
intent.putExtra("Description", descriptionPicked);
PendingIntent addIntent = PendingIntent.getBroadcast(this, remId, intent, 0);
alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, Date.parse(dateTimePicked), addIntent);
}
</code></pre>
<p>For updating a reminder:</p>
<pre><code>databaseManager.updateReminder(remindId, titlePicked2, descriptionPicked2, timePicked, datePicked, dateTimePicked);
startActivity(new Intent(getApplicationContext(), MainActivity.class));
updateAlarm();
private void updateAlarm() {
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), ReminderReceiver.class);
intent.putExtra("DateTime", dateTimePicked);
intent.putExtra("NotifID", remindId);
intent.putExtra("Title", titlePicked2);
intent.putExtra("Description", descriptionPicked2);
PendingIntent updateIntent = PendingIntent.getBroadcast(this, remindId, intent, 0);
alarmManager.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, Date.parse(dateTimePicked), updateIntent);
}
</code></pre>
<p>Receiver class:</p>
<pre><code>public class ReminderReceiver extends BroadcastReceiver {
private static final String CHANNEL_ID = "CHANNEL_REMIND";
String DateTimeChoice, TitleChoice, DescriptionChoice;
int notificationID;
@Override
public void onReceive(Context context, Intent intent) {
DateTimeChoice = intent.getStringExtra("DateTime");
notificationID = intent.getIntExtra("NotifID", 0);
TitleChoice = intent.getStringExtra("Title");
DescriptionChoice = intent.getStringExtra("Description");
Intent mainIntent = new Intent(context, ViewReminder.class);
mainIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(context, notificationID, mainIntent, 0);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
// For API 26 and above
CharSequence channelName = "My Notification";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, channelName, importance);

}

.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setColor(context.getResources().getColor(R.color.purple_700))
.setAutoCancel(true);
notificationManager.notify(notificationID, builder.build());
}
</code></pre>
<p>Adapter class:</p>
<pre><code>int remindId = reminder.getReminderId();

How to print ALL columns of MySQL table in Python?
|
<p>Here I want to print every column present in the MySQL table <strong>(PASSENGER)</strong>, but this code only gives 4-5 columns.</p>
<p>The code:</p>
<pre><code>import pandas as pd
import mysql.connector as myq
d = myq.connect(host="localhost", user="root", passwd="admin", database="air")
df = pd.read_sql("select * from Passengers", d)
print(df)
</code></pre>
<p>Output:</p>
<pre><code> Ticket_Number Date Passenger ... Class Stat Announcement
0 1 1 1 ... 1 1 1
1 184784 1 1 ... 1 1 1
2 184785 1 1 ... 1 1 None

4 184789 9:12:2020 Jeet ... FIRST CLASS CONFIRMED None
5 184790 9:12:2021 Jeet ... FIRST CLASS CONFIRMED None
</code></pre>
<p>This is what Python is returning to my code. Here I want all 12 columns.</p>

Kivy - Draw Rectangle Around Text
|
<p>I'm brand new to Kivy and trying to make a UI for a project. I'm trying to develop an understanding for how everything gets sized in the different layouts.</p>
<p>I'm having an issue where I have two labels side by side in a box layout (nested in another box layout). I want the 2nd label to have a rectangle drawn behind only the text. I can get 90% of the way there, but I'm stumbling over positioning the rectangle behind the text, since there is no "self.texture_pos" like there is "self.texture_size".</p>
<p>How can I dynamically draw a rectangle at the size and position of a label string, or am I doing this a really dumb way?</p>

Why can threads change instance data if it is blocked in another thread?
|
<p>I began to study lock and immediately a question arose.</p>
<p>It <a href="https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/statements/lock" rel="nofollow noreferrer">docs.microsoft</a> says here:</p>
<blockquote>
<p>The lock statement acquires the mutual-exclusion lock for a given
object, executes a statement block, and then releases the lock. While
a lock is held, the thread that holds the lock can again acquire and
release the lock. <strong>Any other thread is blocked from acquiring the lock
and waits until the lock is released</strong>.</p>
</blockquote>
<p>I made a simple example proving that another thread with a method without the lock keyword can easily change the data of an instance while that instance is occupied by a method using the lock from the first thread. It is worth removing the comment from the blocking and the work is done as expected. I thought that a lock would block access to an instance from other threads, even if they don't use a lock on that instance in their methods.</p>
<p><strong>Questions</strong>:</p>
<ol>
<li><p>Do I understand correctly that locking an instance on one thread allows data from another thread to be modified on that instance, unless that other thread also uses that instance's lock? If so, what then does such a blocking generally give and why is it done this way?</p>
</li>
<li><p>What does this mean in simpler terms? <strong>While a lock is held, the thread that holds the lock can again acquire and release the lock</strong>.</p>
</li>
</ol>

<p>So code formatting works well.</p>

Error : You are trying to load a weight file containing 1 layers into a model with 14 layers
|
<p>Since due to having not enough of resources like GPU and Ram we are using Google Colab for training the model but still there are some limitations in it for example maximum time limit for Google Colab's GPU is only 12-hours.
Still we trained the model in those 12- hours but the loss doesn't seem to be changing after 1st epoch, due to which we decide to use Auto-Colorize's code and there trained weight's file <strong>"colorize.hdf5"</strong> that is uploaded on GitHub (code available on github link: <a href="https://github.com/hvvashistha/Auto-Colorize" rel="nofollow noreferrer">https://github.com/hvvashistha/Auto-Colorize</a>) , but on loading those weights we are getting an error. </p>

mat-icon doesn't show icon in dialog after closing and re-opening the dialog
|
<p>I have created a dynamic dialog component, which I can pass action buttons to, which then get displayed in the dialog header. By default, the dialog contains a close action button, and I'm passing an edit action to the dialog header.
This edit action contains two buttons:</p>
<ul>
<li>one select button that changes the dialog content to an edit form if it had not been selected and that cancels the editing if it had been selected prior.</li>
<li>a save button that only displays if the select button had been selected.</li>
</ul>
<p>Both of these buttons are mat-icon-buttons using a mat-icon. This works fine when I open the dialog for the first time, however the icons do not get displayed if I close and re-open the dialog. The close button icon is displayed but neither of the edit action buttons are.</p>
<p>This is where I open the dialog:</p>
<pre><code><div id="btn-add">
<button mat-mini-fab
(click)="add()">
<mat-icon>add</mat-icon>
</button>
</div>
<wb-dialog [title]="selectedArea?.title"
[active]="!!selectedArea"
(onClose)="close()">
<div actions>
<wb-tab-button [tab]="dialogStatusEnum.EDIT"
[form]="areaForm"
icon="edit"
[active]="this.dialogStatus === dialogStatusEnum.EDIT"
(onSelect)="this.tab($event)"
(onSubmit)="saveArea()"></wb-tab-button>
</div>
</wb-dialog>
</code></pre>
<p>And its typescript code:</p>
<pre><code>export class AreaComponent {
public readonly dialogStatusEnum: typeof DialogStatus = DialogStatus;
public selectedArea: Area | undefined;
public areaForm: FormGroup;
constructor(formBuilder: FormBuilder) {
this.areaForm = formBuilder.group({});
}
public add(): void {
this.selectedArea = new Area();
this.isDialogLoading = false;
}
public close(): void {
this.selectedArea = undefined;
}
public tab(tab: DialogStatus | undefined) {
this.dialogStatus = tab || this.dialogStatusEnum.EDIT;
}
public saveArea() {
// TODO!
}
}
</code></pre>
<p>This is the dialog:</p>
<pre><code><div class="mat-dialog-wrapper"
[ngClass]="{'mat-hidden': !active}">
<mat-card *ngIf="active">
<mat-card-header>
<mat-card-title *ngIf="title"
[ngClass]="{'mat-placeholder': !!title}">{{title || 'no title'}}</mat-card-title>
<ng-content select="[actions]"></ng-content>
<button mat-icon-button
(click)="close()"
class="mat-card-header-action"><mat-icon>close</mat-icon></button>
</mat-card-header>
<ng-content select="[content]"></ng-content>
</mat-card>
</div>
</code></pre>
<p>And the component code:</p>
<pre><code>export class DialogComponent {
@Input() title: string | undefined;
@Input() active: boolean;
@Output() onClose: EventEmitter<void>;
constructor() {
this.active = false;
this.onClose = new EventEmitter<void>();
}
public close(): void {
this.onClose.emit();
}
}
</code></pre>
<p>And here's the button:</p>
<pre><code><button *ngIf="active"
mat-icon-button
(click)="submit()"
[disabled]="form.invalid"><mat-icon>save</mat-icon></button>
<button mat-icon-button
(click)="select()"
[ngClass]="{'mat-active': active}">
<mat-icon *ngIf="active">block</mat-icon>
<mat-icon *ngIf="!active">{{icon}}</mat-icon>
</button>
</code></pre>
<p>And its component:</p>
<pre><code>export class TabButtonComponent {
@Input() tab!: DialogStatus;
@Input() form!: FormGroup;
@Input() icon: string;
@Input() active!: boolean;
@Output() onSelect: EventEmitter<DialogStatus | undefined>;
@Output() onSubmit: EventEmitter<void>;
constructor() {
this.onSelect = new EventEmitter<DialogStatus | undefined>();
this.onSubmit = new EventEmitter<void>();
}
public select(): void {
this.onSelect.emit(this.active ? undefined : this.tab);
}
public submit(): void {
this.onSubmit.emit();
}
}
</code></pre>
<p>The only similar thing I found is this question <a href="https://stackoverflow.com/questions/55797323/message-wont-display-a-second-time-after-being-closed">message-wont-display-a-second-time-after-being-closed</a>. However, all my bindings work, the click event handlers, the dynamic mat-active CSS class, all of the elements exist in my DOM, the buttons as well as the icons and I couldn't find any difference in the CSS when I compare the first with a subsequent dialog call. The only issue I have is that the icons are not being displayed and I can't figure out why that is or how to fix it.</p>
<p>If I place the tab button directly in the dialog instead of inserting it from the parent this issue does not occur.</p>

How to force CLion using a custom MSVC version?
|
<h1>The problem</h1>
<p>I use CLion 2022.2, Visual Studio 2022, and CMake 3.23. I want to use the toolset of version 14.31.17.1, which is older than the newest one.</p>
<h1>Configure</h1>
<p>I configure the CMake project with a <code>CMakeLists.txt</code> file</p>
<pre><code>project(test_project)
add_executable(test_project main.cpp)
</code></pre>
<p>In CLion, I specify generator Visual Studio 2022 and a toolset 14.31.17.1. The command executed is</p>
<pre><code>"C:\Program Files\CMake\bin\cmake.exe" -G "Visual Studio 17 2022" -T version=14.31.17.1 -S F:\test_project -B F:\test_project\build
</code></pre>
<p>Nevertheless, logs say</p>
<pre><code>-- The C compiler identification is MSVC 19.33.31629.0
-- The CXX compiler identification is MSVC 19.33.31629.0
</code></pre>
<p>When I clear the cache directory and execute the same command in CLion Terminal (copy and paste it with the <code>.</code> or <code>&</code> prefix), I get what I want</p>
<pre><code>-- The C compiler identification is MSVC 19.31.31107.0
-- The CXX compiler identification is MSVC 19.31.31107.0
</code></pre>
<p>Note: toolset 14.31.31103 contains MSVC 19.31.31107.0 while toolset 14.33.31629 contains MSVC 19.33.31629.0. So I conclude that something goes wrong.</p>
<p>After this, I can modify the project and execute the "Reload CMake Project", and CLion does it well because the versions of compilers are already configured.</p>
<p>Specifying C and C++ compilers for the toolchain (File | Settings | Build, Execution, Deployment | Toolchains) doesn't help.</p>
<p>When I remove the latest toolset using Visual Studio Installer, it also automatically removes C++ CMake Tools for Windows, which doesn't allow me to use CMake with Visual Studio.</p>
<h1>Build</h1>
<p>My <code>main.cpp</code> file is</p>
<pre class="lang-cpp prettyprint-override"><code>#include <iostream>
int main() {
std::cout << _MSC_VER << std::endl;
return 0;
}
</code></pre>
<p>When I configure the project (no matter with CLion or manually) and build it using CLion GUI, I get the answer</p>
<pre><code>1933
</code></pre>
<p>Although, if I use the same command as CLion, namely</p>
<pre><code>"C:\Program Files\CMake\bin\cmake.exe" --build F:\test_project\build --target test_project --config Debug
</code></pre>
<p>I get what I need</p>
<pre><code>1931
</code></pre>
<p>The strange part is that I get the correct result using Terminal even after configuring the project using CLion GUI. Also, I can set up the project in Terminal to use the newer toolset (which is the default) and have the <code>1933</code> printed.</p>
<p>Also, when I debug the code using CLion, the Evaluate says that <code>_MSC_VER</code> is <code>1933</code> but the application still prints <code>1931</code>. When I create a variable <code>int x{_MSC_VER};</code>, the debugger shows that <code>x</code> equals <code>1931</code>.</p>
<h1>Summary</h1>
<p>If I use CLion GUI to configure or build the project or to do both things, it uses MSVC 19.33.31629.0.
If I configure and build the project in CLion's Terminal using the same commands CLion shows me when configuring and building the project, I can use MSVC 19.31.31107.0.</p>
<p>Am I missing something? Does CLion specify environment variables I should override? Is it possible to choose the MSVC version I need using CLion?</p>

How to dynamically adjust the number of rows in a table to pad table elements in bootstrap?
|
<p>I currently have a balance sheet table. On the left hand side is all the assets and the right hand is all the liabilities. There are short and long-term assets and short and long term liabilities. Currently my table looks like:</p>
<pre><code>Assets Liabilities
Short-term Long-term
Cash Bond 1
Accounts Receivable Bond 2
Long-term
Plants
</code></pre>
<p>The number of items under short/long-term asset/liabilities will change over time. So I'm looking for a solution to automatically adjust to the number of items I might have under each category. Is there a easy way in bootstrap to dynamically pad the column such that rows of similar qualities are aligned or do I need to pre-process this in Django first before outputting the results? like this?</p>
<pre><code>Assets Liabilities
Short-term
Cash
Accounts Receivable
Long-term Long-term
Plants Bond 1
Bond 2
</code></pre>
<p>Here is the html:</p>
<pre><code><div id="balance_sheet" class="container-fluid">
<div class="container-fluid col-sm-6 right-side">
<table style="width:100%">
<tr>
<th> Assets </th>
</tr>
<tr>
<th>{{ account_receivable_title }}</th>
<th>Balance</th>
</tr>
{% for account_receivable in account_receivables %}
<tr>
<td>{{ account_receivable.name }}</td>
<td>${{ account_receivable.balance }}</td>
</tr>
{% endfor %}
<tr>
<th>{{ account_plant_title }}</th>
<th></th>
</tr>
{% for account_plant in account_plants %}
<tr>
<td>{{ account_plant.name }}</td>
<td>${{ account_plant.value }}</td>
</tr>
{% endfor %}
<tfoot>
<tr>
<td>{{ account_total_name }}</td>
<td>${{ user_asset_total }}</td>
</tr>
</tfoot>
</table>
</div>
<p>
<p>
<div class="container-fluid col-sm-6 left-side">
<table style="width:100%">
<tr>
<th> Liabilities</th>
</tr>
<tr>
<th>{{ account_credit_title }}</th>
<th>Balance</th>
</tr>
{% for account_credit in account_credit %}
<tr>
<td>{{ account_credit.name }}</td>
<td>${{ account_credit.balance }}</td>
</tr>
{% endfor %}
<tr>
<th>{{ account_bond_title }}</th>
<th></th>
</tr>
{% for account_bond in account_bonds %}
<tr>
<td>{{ account_bond.name }}</td>
<td>${{ account_bond.balance }}</td>
</tr>
{% endfor %}
<tfoot>
<tr>
<td>{{ account_total_name }}</td>
