How to create a DjangoModel Form with a model that contains FKs and M2M relationships
I have seen posts that talk about this scenario separately but they seem to be very old, using old documentation. I am here wondering if there is a new fix. Also I'm relatively new to django and they have been quite confusing. I would like to create a Form that takes in the relevant information to be able to create a parking space object. This is the Forms.py class AddParkingSpace(forms.ModelForm): class Meta: model = ParkingSpace fields = [ "__all__"] exclude = ["reviews","seller_account"] # widgets to include all the fields like fields not in the specified model above (explained below) widgets = { } I have excluded the reviews because these will be added to the parking space object as and when a review is submitted. The seller_account will be added to the parking space in the view(backend). Using this form I would like to be able to access each field separately using the Django syntax {{formname.fieldname}} in the template. So I can style/position it how I desire I Models.py class ParkingSpace(models.Model): name = models.CharField(max_length=50,blank=False) # name of a parking space description = models.TextField(blank=False)# the description of a parking space image = models.ImageField(null=True,upload_to="images/parking_spaces") #The image of a parking space price = … -

DRF and FactoryBoy for testing - testing viewset logic - saving factory to database?
I'm currently working on testing a Django Rest Framework (DRF) application using Factory Boy. In my setup, I have a straightforward model, serializer, and viewset (specifically, a ModelViewSet). As part of my testing process, I'm making some modifications to the logic within the ModelViewSet, particularly by customizing the perform_create method. And it is the part what I want to test - viewset logic. However, while using Factory Boy, I've observed that the perform_create method is not being triggered by Factory Boy's default behavior. I'd appreciate any suggestions or insights on how to ensure that perform_create is invoked when using Factory Boy in my tests. Maybe I should call perform_create manually? Alternatively, if you think it might be more appropriate to explore other testing frameworks or methods for this scenario, or if using the simple APIClient for testing would be a better approach, I'd welcome your guidance on that as well. Thank you, and have a wonderful day! -

Why Django DRF Response is not working right on live server with 204 content status?
I have a delete_rider view that works fine with @action(detail=False, methods=['DELETE'], permission_classes=[IsAuthenticated]) def delete_rider(self, request): """Delete the authenticated rider if the user's rider.""" user = request.user # Check if the user is a rider (role 2) if user.role == 2: user.delete() # Delete the user return Response(status=status.HTTP_204_NO_CONTENT) else: return Response({"message": "User is not a rider (role 2)."}, status=status.HTTP_400_BAD_REQUEST) on local server. But on live server it gets stuck in request and after some seconds it times out although delete the user but time out. HttpResponse instead of Response worked.

How can I log in in an API with Python?
Good afternoon, everyone, I have a question about how I can log into an API through Python code. I want to "identify" the API login so that the user can see which invoices are pending, i.e. a user logs in with my Django login, which, at the same time, has to log in to the API. Once logged into the api, I want the api to return the documents that have an id with its assigned tag. I attach below the function that I have made and that connects me to the database. This function does not return any information from the API because of what I said, because first you have to identify which user is logged in. @login_required def f_facturaspendientes(request): # URL de la API a la que deseas conectarte url = 'http://host.docker.internal/api/v4/documents/' try: response = requests.get(url) if response.status_code == 200: # La solicitud fue exitosa, puedes procesar la respuesta aquí data = response.json() # Hacer algo con los datos de la API # Devuelve una respuesta JSON con los datos procesados return JsonResponse({'message': 'Solicitud exitosa', 'data': data}) else: # La solicitud no fue exitosa, maneja el error aquí si es necesario return JsonResponse({'error': 'Error en la solicitud', … -

Celery worker processes django task but does not execute
I am a beginner. I have a django project in which I am trying to add a functionality where I send a welcome email when a user signs up. I am using the django development server on 127.0.0.1:8000, a celery worker, and a docker container running redis on redis://127.0.0.1:6379. When I sign up a test user, no welcome email prints to the console (current email config is EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' so that would be the expected result. Contents of my tasks.py @shared_task def send_welcome_email(user_email): print("send welcome email started") subject = 'Welcome to My Website' message = 'Thank you for registering at My Website!' from_email = 'noreply@mywebsite.com' recipient_list = [user_email] print(f"Sending email to {user_email}") send_mail(subject, message, from_email, recipient_list) print("Email sent") I have done necessary configuration such as adding the celery app to my project's init.py, adding Celery settings (broker URL and result backend), a celery.py file in my django project, and I have also confirmed that Celery is connected to my redis database. When I check the status of the task with Flower, I see that a Celery worker has received the task, and it is listed under 'Processed', but does not move to Failed or Succeeded, and as stated, no … -
Trying to fix a Django error calling a Module that doesn't exist for an SQLite Database
I'm designing a website using Django and SQLite, using Models to parse information between the database and the front-end. I'm encountering errors that are limiting my developmental process, as I'll explain below.

Django Snippets/Updating Primary Key
I have a client that requested (after launch) to start their records at a very large number (3,000,000). The model itself has at least 10 relationships/reverse relationships all through FK, established with "on_delete=CASCADE". Originally I was working with this snippet: https://djangosnippets.org/snippets/10619/, which gave quite a few errors. After some formatting (removing %s formatting for easier to read f-string formatting), the script ran but gave the dreaded: Cannot delete or update a parent row: a foreign key constraint fails. I am looking at any sort of way to get the 100 or so records (and their respective relationships) to update accordingly. I have already updated the MYSQL database to start numbering from the last record + 3,000,000 so that any resulting scripts should not result in a collision keeping the PK restraints. I believe there used to be a way to do this via a simple model.objects.all().update(id=F('id')+3000000), but this also has failed in Django 4.2. Any help is appreciated. d -
