Override Bootstrap 4 Colors in PyCharm Django Project - Error: Can't find stylesheet to import
I am trying to import Bootstrap 4's bootstrap.scss file as described in Bootstrap's theming documentation. My IDE is PyCharm.

How to execute the content based on dictionary data using if and else condition in django template?

Inline formsets with django viewflow frontend
I can get an inline formset to work fine with django, but when trying to use viewflow and the built-in workflow frontend, I can't seem to get the inline form to work during the workflow. What is the proper way to reference the formset? Since the workflow models inherit from the viewflow.models.Process object, I can't seem to understand how to create the inline related model. Use case: I have a workflow with about 50 various fields and I can run the workflow just fine using the Flow and breaking up the process in logical parts in about 10 steps. However, After the process is started and the first 3 or 4 fields are entered, I want step 2 to be an inline form where various roles are assigned to users for this particular workflow event. I already have a separate table where they are manually assigned to roles and I can have the Flow assign the next task to whomever is assigned to that "steps" role and it works fine, but I want the action of assigning the roles to be part of the actual workflow itself. I suspect I should add the inlineformset as a field of the parent … -

How to create a weekly summary of dated records in model django
I have a model that has entries for each day. I want to create a queryset with a subtotals (annotates) for a selection of fields in the model. This is what i have so far. Here is the model (or some of it!) class Shiftlog(models.Model): date = models.DateField(default=timezone.now) onlinetime = models.DurationField() trips = models.IntegerField(default=0) km = models.IntegerField(default=0) def weekcom(self): weekcom = self.date - timedelta(days=self.date.weekday()) return weekcom Here is the view code that represents what I am trying to achieve. report = Shiftlog.objects.values('weekcom').annotate(Sum('km')) Now this does not work. I see from other posts that the annotate functionality only works with model fields. I appreciate I can create a dictionary of weekcom (weekcommencing rows) and iterate through the model to populate some k,v buckets for each row (weekcom). However, this does not feel right. I also appreciate that this can be done in SQL directly (I have not gone to this option yet so i don't have the code), but I am trying to avoid this option too. Any guidance, much appreciated. Thanks! -
Django ORM: Filtering by array contains OuterRef within a subquery yields zero results
Here's an isolated ORM query: Purpose.objects.annotate( conversation_count=SubqueryCount( Conversation.objects.filter(goal_slugs__contains=[OuterRef("slug")]).values("id") ) ) Where SubqueryCount is: from django.db.models import IntegerField from django.db.models.expressions import Subquery class SubqueryCount(Subquery): template = "(SELECT count(*) FROM (%(subquery)s) _count)" output_field = IntegerField() When that query is run, the following sql is used (via djdt explain): SELECT "taxonomy_purpose"."id", "taxonomy_purpose"."slug", ( SELECT count(*) FROM ( SELECT U0."id" FROM "conversations_conversation" U0 WHERE U0."goal_slugs" @> ARRAY['ResolvedOuterRef(slug)']::varchar(100)[] ) _count ) AS "conversation_count" FROM "taxonomy_purpose" Note the ResolvedOuterRef(slug) injected into the ARRAY lookup as a string. Am I doing something wrong, or should I report this as a bug? If this is a bug, is there a known workaround (maybe creating a custom OuterRef class)? -
RecursionError when uploading certain images
I am attempting to create a model with an image input that is to be resized and hashed along with a thumbnail on save. However, I appear to to have created an infinite recursive call. Some images upload, create thumbnails, and generate hashes without issues, but one image causes the program to call self.thumbnail.save(new_name, img_file) (the last line of generate_thumbnail) endlessly. How can I save the image and avoid the recursive call? Any help is appreciated. This is a slightly different issue than my last question, RecursionError when trying to save image. Below are some properties of the image files I used which may or may not be relevant.

Change between muiltiple databases with Django

Django templates won't load but HttpResponse will

My problem is quite simple: whenever I try to run my homepage with a template, it throws up a 404 error.

Also, whenever I change return render(request, 'dashboard.html') to return HttpResponse('home') in my home function, it decides to show. -

Why doesn't my dynamically generated stylesheet (Django) get applied by my html pages?
I am using Django and have set up a view that returns a dynamically generated stylesheet to allow for user themes. I link the stylesheet in the head section of my pages with, <link href="/theme.css" rel="stylesheet"> I can see the request for /theme.css at the server and a successful response. I can also view the source of the page in the browser and it shows the correct contents for the stylesheet. However, for some reason the styles in theme.css are not applied to the page. If I place the contents of the dynamically created stylesheet into a static file and change the link like so, <link href="/static/rml/css/theme.css" rel="stylesheet"> the styles are correctly applied. I can't see why there is a difference. I have looked for answers and can't find anything relevant. -

I have product cards that each have a player. What is expected: Each player should play its own track when clicked on the play button. What is happening right now: When I click on any of the play buttons it plays the first track only. Here is my code: let isPlaying = false let playBtn = document.querySelectorAll('.playerButton'); for (var i = 0; i < player.length; i++) { if (playBtn != null) { playBtn[i].addEventListener('click', togglePlay); } } // Controls & Sounds Methods // ---------------------------------------------------------- function togglePlay() { let player = document.querySelectorAll('.player') if (player.paused === false) { player.pause(); isPlaying = false; document.querySelector(".fa-pause") .style.display = 'none'; document.querySelector(".fa-play") .style.display = 'block'; } else { player[0].play(); document.querySelector(".fa-play") .style.display = 'none'; document.querySelector(".fa-pause") .style.display = 'block'; isPlaying = true; } } {% for product in products %} <div class="card-trip"> <div class="player-section"> <img src="{{ product.image.url }}" /> <div class="audio-player"> <a class="playerButton"> <span> <i class="fas fa-play"></i> </span> <span> <i class="fas fa-pause"></i> </span> </a> <audio id="player" class="player"> <source src="https://api.coderrocketfuel.com/assets/pomodoro-times-up.mp3"> Your browser does not support the audio element. </audio> </div> </div> <div class="card-trip-infos"> <div> <h2>{{product.name}}</h2> <p>{{product.description}}</p> <button class="btn" type="button">buy now - ${{product.price}}</button> <p>{{product.tag}}</p> </div> </div> </div> {% endfor %} -
Django 3.0.4 brings ASGI. Makes sense continue patching things with gevent?
I've tried run my django project through uvicorn but it led to the following error: DatabaseWrapper objects created in a thread can only be used in that same thread My django project patched things for gevent: the default gevent path_all plus psycogreen patch. Remove these patches makes the uvicorn works. But Why this errors occurs, is ASGI incompatible with gevent? -
How would I create a page fo a tournament that lets the user choose who won the match?
I currently have a page for each tournament on my website and this shows basic info (rules, creator, etc.). I want to create a page (linked to on this page) which shows all the matches for the round of the tournament I have calculated and then lets you pick which team won from the two. For example Team1 vs Team2 Click the winner I have a table called Match class Match(models.Model): team = models.ForeignKey(Team, on_delete=models.CASCADE) score = models.IntegerField(db_column='Score', null=True) tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE) winner = models.BooleanField(db_column='Winner', null=True) How do I create a page that enables me to change the winner field with a button or something else? Please let me know if you need any more information
