can I use the slug from a different urls.py file?
I'm trying to access a slug field from a different urls.py file, and I'm getting this error FieldError at /new-api/tournaments/fifa-world-cup/teams/ Unsupported lookup 'custom_url' for ForeignKey or join on the field not permitted. I'm wondering if the reason I'm getting this error is because you cant do that or if it's another reason I have 2 files for urls, one includes the other in it, urls.py (tournament) urlpatterns = [ path("", views.getNewTournaments, name="tournaments"), path("<slug:custom_url>/", views.getNewTournament, name="tournament"), path("create/", views.postNewTournament, name="post-tournament"), path("<slug:custom_url>/teams/", include("teams.urls"), name="tournament-teams"), ] urls.py (teams) urlpatterns = [ path("", views.teams.as_view(), name="teams"), ] Here are the views.py files views.py (tournaments) @api_view(["GET"]) def getNewTournaments(request): tournaments = NewTournament.objects.all() serializer = NewTournamentSerializer(tournaments, many=True) return Response(serializer.data) views.py (teams) class teams(APIView): def get(self, request, custom_url): teams = Team.objects.filter(tournament__custom_url=custom_url) serializer = TeamSerializer(teams, many=True) return Response(serializer.data) -
Django JWT authentication TokenObtainPairView issue
I am trying to use CustomTokenObtainPairView to receive my username in token. #views: `if user.check_password(password): # refresh = RefreshToken.for_user(user) # refresh.access_token['username'] = user.username # token = str(refresh.access_token) request.data = { 'username': username, 'password': password } token_response = CustomTokenObtainPairView.post(request=request.data) response = Response() response.set_cookie(key='jwt', value=token_response.data['access'], httponly=True, secure=True) response.data = { 'access': token_response.data['access'] } return response else: return Response({'message': 'Wrong password!'}, status=400)` I tried to generate token and adding username in it but it didnot work.

How to properly assign a value to a Django choice field
I am trying to assign a value to a ChoiceField in a Django form. # forms.py MONTH_CHOICES = ( ("JANUARY", "January"), ("FEBRUARY", "February"), #... ("DECEMBER", "December"), ) class SomeMonthSelectingform(forms.Form): month = forms.ChoiceField(choices=MONTH_CHOICES) def __init__(self, *args, **kwargs): month = kwargs.pop("month") super(SomeMonthSelectingform, self).__init__(*args, **kwargs) self.fields['month'] = month The selected value of the choice field named month should be the actual month (e.g. right now it would be 'JULY') # views.py def month_view(request: HttpRequest): month = datetime.now().month monthIndex = month - 1 monthChoice = MONTH_CHOICES[monthIndex][0] monthForm = SomeMonthSelectingform(month=monthChoice) if request.method == 'POST': filledForm = SomeMonthSelectingform(data=request.POST) if not filledForm.is_valid(): raise Exception("Month form was invalid") monthForm = filledForm args = { 'monthForm': monthForm } return render(request, 'month.html', 'args') <!-- month.html --> {% extends 'base.html' %} {% block content %} <h2>Month</h2> <form action="{% url '...' %}" method="post"> {% csrf_token %} {{ monthForm }} <input type="submit" name="..." value="Show"> </form> {% endblock %} Sadly, I keep getting the error 'str' object has no attribute 'get_bound_field'. I am quite sure it is because, I should not assign 'JULY' to self.fields['month'] inside the constructor of the form. But I can not find another solution. -

How to implement Bootstrap Card Layout in Django: Achieving Desired Design vs. Current Output
I'm working on a Django application. I'm mostly working on the backend because of that in the frontend I'm terrible. I want to create a page that contains a couple of cards.

Why Gemini API function calling response using old function definition even after changing tools in genai.GenerativeModel?
I want to build a django application that uses Google Gemini API at the backend. The challenge I have is that , the function call parameters change ( though very rarely ) based on a database entry. consider I have an enum as input arg to the function and whenever a new row is created I want to add new enum to this function definition. so this change take place quickly. but unfortunately this doesn't happen, instead the Gemini responds with response that looks it doesn't know about the change. Note I have configured the the flow to call genai.GenerativeModel for every new request and verified that self.function_collection.getdef() returns the updated function definition when I update the a row. self.model = genai.GenerativeModel( model_name=config('GEMINI_MODEL_NAME'), generation_config={ "temperature":config('TEMPERATURE',cast=float), "top_p": config('TOP_P',cast=int), "top_k": config('TOP_K',cast=int), "max_output_tokens": config('MAX_OUTPUT_TOKENS',cast=int), "response_mime_type": "text/plain", }, tools=[{ 'function_declarations': self.function_collection.getdef(), }], ) If I restart django development server this change will be quickly considered. but I can't do this in production. Also I have verified this change is available to the model using the following chat_session = self.model.start_chat(history=self.history) print("tools avaialbe",self.model._tools.to_proto()) print("function def",self.function_collection.getdef()) print("tools avaialbe in session before ",chat_session.model._tools.to_proto()) response = chat_session.send_message(query) print("tools avaialbe in session after ",chat_session.model._tools.to_proto()) I verified that the updated function … -
Django send just an alter in response instead of a full template

Django modal window
I have a modal window for deleting comments. It looks like this: <div id="deleteModal" class="modal"> <div class="modal-content"> <img class="modal-image" src="{% static 'img/icon-modal-delete.png' %}" alt="DELETE"> <h1 class="modal-title">Delete comment?</h1> <div class="modal-block"> <form method="POST"> {% csrf_token %} <button class="modal-sucsess" type="submit">Delete</button> </form> <a class="modal-cancel" onclick="closeModal()">Cancel</a> </div> </div> </div> I include it with the include tag in the django template. There is also a js script for opening and closing the modal window, which looks like this: function openModal() { var modal = document.querySelector('.modal'); modal.style.display = 'block'; } function closeModal() { var modal = document.querySelector('.modal'); modal.style.display = 'none'; } In the django template I have a cycle where I display comments to the publication and each comment has a delete button, which on click calls a modal window, it looks like this: <a class="main-row-content-comments-users-info-delete" onclick="openModal()" >Delete</a> I wrote a view to delete a comment, but it needs to pass the comment id. If I were doing this directly via a link in a template tag, I would simply pass comment.pk, but how do I pass the key to the modal so that when I click the delete button in the modal, the delete view is called? I tried to solve this using Ajax requests, but … -
Lightsail deployment logging; Invalid HTTP_HOST header:You may need to add '****' to ALLOWED_HOSTS
I am deploying a containerised application on Lightsail and whilst the deployment itself is successful, logging shows hundreds of these messages from the same ip address, my assumption is this is some sort of automated process that's failing. I have set the allowed_hosts to just the Lightsail generated url (w/o https//.com etc.) and so I have no idea where this extra ip is coming from. I can't find anything which says I need to have an extra ip on allowed_hosts. Tried to deploy containerised application to Lightsail -

Problem with authentication of login in Django
When trying to authenticate a user using the "authenticate" method, it won't let me log in. I don't know if it is because the authentication method no longer works in new versions of django, or if another method is used. I'm new to django, so I'm just learning: def signin(request): if request.method == 'GET': return render(request, 'signin.html', { 'form': AuthenticationForm }) else: # POST user = authenticate(request, username=request.POST['username'],password=request.POST['password']) if user is None: return render(request, 'signin.html', { 'form': AuthenticationForm, 'error': 'Username or password is incorrect' }) else: login(request, user) return redirect('tasks') In the login template, the indicated method is POST, so that is not the problem there.I tried to change the login name to avoid any conflict, and it was not resolved. -
Count by Month in Django Query
Good afternoon, I am struggling with a query. Ultimately, I have some records I want to query and get a count by month. Ultimately, my goal is to come up with a data set that looks like: Month, opened, closed Jan, 2, 3 Feb, 1, 5 Etc... for the past six months. I have been using this as a base: Django: Query Group By Month This works to get each individually: six_months_ago = datetime.now() - timedelta(days = 180) open_six_months = (Rec.objects .annotate(open=Month('open_date')) .values('open') .annotate(rec_opened=Count('status', filter=Q(status__is_open=True))) .order_by()) closed_six_months = (Rec.objects .annotate(closed=Month('close_date')) .values('closed') .annotate(rec_closed=Count('status', filter=Q(status__is_open=False) and Q(close_date__isnull=False) )) .order_by()) Not all records have a closed date yet. This returns the right data when testing, but its in two different queries. I'd like to have one single data set if possible. Is there an easy way to combine this into one query that has a single row with both the count of the open date and the count of the closed date by month? Thank you for your help. BCBB -
Why can't I save the Django FileField with a null value
I want to use a POST request to create an object with file fields. At the same time, at the model level, I declared that fields can be null. But Django does not allow me to save this object with empty values in the file fields. At the same time, through Django admin, I can create an object with without specifying a file. Error: ValueError: The 'image_before' attribute has no file associated with it. What could this be related to? My request: { "type": "Type", "question": "Text", "category": [ 1 ] } My model: class Question(models.Model): class Meta: db_table = 'questions' question_type = models.CharField( max_length=300, ) category = models.ManyToManyField( Category, ) question_text = models.CharField( max_length=300, ) image_before = models.ImageField( upload_to='media/', null=True, blank=True, default=None, ) correct_answer= models.CharField( max_length=300, blank=True ) I tried to redefine save() and change the value of the field to None there. Then the value of the field will be <FileField: None> -
Mutliple JWT generation with different django secrets based on subdomains
I am using simple JWT (django-rest-framework-simplejwt). I have an auth server which authenticates users. Each user can belong to a single or multiple Tenants and each tenant is represented by a subdomain. I am trying to generate django secret for each tenant and when the tenant docker launches it uses the django secret generated by the auth server(i store it in .tenant1.local.env for tenant one) So when a user tries to connect to a domain, system will create auth token using the secret generated for that tenant. Since that tenant will have an access to .tenant.local.env (same secret that was used to generate the token for that tenant) it ll be able authenticate the users using the secret. The issue is I can not find a simple way to inherit or overwrite a class in django-rest-framework-simplejwt so that I can specify the secret to use to create the token. There is APISettings(which you specify which secrets to use) in the package but there is no example of how to use it. IS there a way to specify which secrets to use per access token generation request instead of initializing the whole API for each request. -

Heroku DB Connection Limit hit when using Python ThreadPoolExecutor
I have a Django app hosted on Heroku. Some user requests to this app require making long-running queries to external resources. In order to get around the Heroku 30 request timeout, I created a system where these long running queries are given unique IDs and handed to a Python ThreadPoolExecutor so as not to hold off the query. The original query returns immediately and the font end JS code periodically checks in for a results. This system is working great but since deploying that change I routinely get "FATAL: too many connections" errors from my app. It appears as though the automatic connection management Django provides doesn't work when ThreadPoolExecutors are in use. Unfortunately I have to have access to the DB from the spawned thread in order to save the results of the long-running query. Any recommendation as to how I can fix this so DB connections are managed correctly? -
