UNIQUE constraint failed: home_profile.user_id - Django
I am just trying to mix my Profile model with my User one. I was following this Django series: https://www.youtube.com/watch?v=KXunlJgeRcU&list=PLCC34OHNcOtoQCR6K4RgBWNi3-7yGgg7b I accidentally deleted one of my users, so I tried recreating them again and got this error: UNIQUE constraint failed: home_profile.user_id I tried solving the issue with this answer: https://stackoverflow.com/a/60282442/19641902 ... but it gave me another error: 'User' object has no attribute 'profile' Also when I create the users in the database manually, it automatically creates three-four profiles in the User section of my database.

can't access to tenant schemas in Django-tenant
I'm having problems accessing tenant schemas. So far I have been able to create schemas and tenants in the database. I'm creating tenants using tenant.localhost (no port) as domain, for localhost testing.

How can I access Property Owner Details in Django
I have a Django View where all users (Landlord, Agent and prospect) can access and on this view, I want to display the name of the property owner on my template but I am only getting None displayed whenever a Prospect user is on the view. Understand that the three users have their Models with a OneToOneField relationship with the User Model. And I also have a Profile Model with the same relationship with the User Model. See the view code below: def property_detail(request, property_id): user = request.user #Check if user is authenticated if user.is_authenticated: #Check if user is Landlord if hasattr(user, 'landlord'): properties = Property.objects.filter(landlord=user.landlord).prefetch_related('agent').order_by('-last_updated')[:4] property_owner = user.landlord.profile if hasattr(user.landlord, 'profile') else None #Check if user is Agent elif hasattr(user, 'agent'): properties = Property.objects.filter(agent=user.agent).prefetch_related('landlord').order_by('-last_updated')[:4] property_owner = user.agent.profile if hasattr(user.agent, 'profile') else None else: properties = Property.objects.order_by('-last_updated')[:4] property_owner = None #Get the Property by its Product key from DB property_instance = get_object_or_404(Property, pk=property_id) #Send Notification to property owner if request.method == 'POST': form = MessageForm(request.POST) if form.is_valid(): content = form.cleaned_data['content'] subject = form.cleaned_data['subject'] Message.objects.create(property=property_instance, sender=user, recipient=property_owner, subject=subject, content=content) messages.success(request, 'Notification sent successfully with your Contact Details.') else: form = MessageForm() context = { 'form':form, 'properties':properties, 'property_owner': property_owner, 'page_title': 'Property Detail', … -

No POST/create form in DRF Browsable API?
I am using Django Rest Framework (Django version=4.0.4, I know I need to upgrade, but I'm still learning the ropes and djangorestframework~=3.14.0) and Viewsets for an API, but I can't get the Browsable API POST form to show up on the list page. I can see the list of ParameterKeys (so I think urls.py and serializers.py are correct) and I'm using a superuser account so I don't think it's a permissions thing. What's wrong with my setup?

CKEditor5Field not displaying correctly in read-only mode for restricted user roles in Django Admin
I'm encountering an issue with the CKEditor5Field in Django Admin when it's set to read-only mode for users with restricted roles. Specifically, when I log in with a user role that has write permissions, the CKEditor5Field works perfectly and displays the formatted text as expected. However, when I log in with a user role that only has read permissions, the CKEditor5Field does not render the HTML content properly. Instead, it displays the raw HTML tags without any formatting. models.py class SalesInfo(models.Model): feature_id = models.OneToOneField( FeatureFilm, on_delete=models.CASCADE, null=True, blank=True, editable=False ) ... sales_info = CKEditor5Field( verbose_name="Vertriebs Notizen", config_name="extends", null=True, blank=True ) ... admin.py class SalesInfoSetInLine(admin.StackedInline): raw_id_fields = [ "feature_id", "tv_movie_id", "tv_serie_season_id", "special_project_id", ] read_only_fields = [ "feature_id", "tv_movie_id", "tv_serie_season_id", "special_project_id", ] model = SalesInfo exclude = ["is_sound_restoration_offer"] classes = ["collapse"] extra = 1 # 1 is here ok formfield_overrides = { models.TextField: {"widget": Textarea(attrs={"rows": 12, "cols": 150})}, } I have also confirmed that I have correctly configured the CKEditor5 static files.

Handling delayed responses from server - Django Web App
I have a situation where a user is filling in a form on a django web app. Under normal circumstances the user will submit the form, the server will store the form in the db and display a success message. But, under the assumption that there are multiple users trying to submit the form at the same time and the server is timing out due to large amount of requests, I want to find and integrate a solution that acts as a queue and stores the data of the users when it is free instead of giving timeouts to the users. I want to do this since I do not want the users to fill in the form again from scratch. So, what is the best solution to this problem apart from increasing the server timeout settings? What package or method do I need to use to avoid the user's request from timing out and to be able to successfully store the user's form regardless of the delays. Note: I want to host my webapp on a single shared server, due to budget limitations I cannot afford a Load Balancer and multiple servers even though adding multiple servers will solve … -
Getting Error In Swagger(drf_yasg library) For Nested Serializers in Django

Is Django Template legacy?
Django, as a backend framework, has the main purpose of returning JSON-format data to the frontend developer. So why do we need templates to render HTML with Django? We can use React for the frontend and Django for the backend to provide data via API. The problem is: is this technology a legacy? Does anyone or the company use templates to render the frontend using Django for now in a real project? Also, I am a noob in backend development, so can anybody tell me what backend developers work on exactly except create APIs and make databases? -
