Django ERROR: there is no unique constraint matching given keys for referenced table
There are many similar questions on Stackoverflow, but none of the answers has helped me. So, when running migrations, Django throws this error: django.db.utils.ProgrammingError: there is no unique constraint matching given keys for referenced table "catalogues_movieslist" I have this BlackWhiteCartoon model I am trying to create with the migration: class BlackWhiteCartoon(BaseMovie, BaseList): authors = JSONField(default=list, blank=True, null=True) publisher = CharField(max_length=250, blank=True) year = PositiveSmallIntegerField(blank=True, null=True) This model inherits from the BaseList model that has only one field, a foreign key: class BaseList(Model): belongs_to_movies_list = ForeignKey(MoviesList, on_delete=CASCADE, null=True) The referenced MoviesList model is the following: class MoviesList(Model): creation_date = DateTimeField(auto_now_add=True) id = AutoField(primary_key=True) uid = UUIDField(default=uuid.uuid4, editable=False) user = ForeignKey(User, on_delete=CASCADE, null=True, blank=True) Also, the BaseMovie model is the following: class BaseMovie(BaseObject): language = CharField(max_length=2, blank=True) note = CharField(max_length=700, blank=True) And the BaseObject model: class BaseObject(Model): id = BigAutoField(primary_key=True) uid = UUIDField(default=uuid.uuid4, editable=False, db_index=True) date_added = DateTimeField(null=True) So, what I have tried: Migrating everything together: this throws the above error. Migrating BlackWhiteCartoon without inheriting BaseList first. This migration applies, but as soon as I add BaseList, it crashes with the same error. Adding unique=True to the id field of MoviesList (both together with all other migrations and before adding BaseList to … -
Specific Fields for Specific User types in Django
I'm trying to come up with a better structure for handling user data in a django app. Currently, There are two kinds of users in the app, individual and organization. There is data specific to an individual and data specific to an organization. For example, an individual can have a first and last name while a organization only has their organization name. This is how the model currently looks class CustomUser(AbstractUser): first_name = models.CharField(_('first name'), max_length=30, blank=True) # from AbstractUser last_name = models.CharField(_('last name'), max_length=150, blank=True) # from AbstractUser organization_name = models.CharField(_('organization name'), max_length=180, blank=True) is_individual = models.BooleanField(default=False) is_organization = models.BooleanField(default=False) Is there a way specific fields can be set up for specific user types? Something like: Individual -- first_name -- last_name # more data concerning individuals Organization -- organization_name # more data concerning organizations -

Django Rest Framework: use create with primary key in URL
I can't apply the @action decorator to create function within a standard views.Viewset subclass. @action(detail=True) # This fails. def create(self, request, pk=None): return Response(etc...) On other methods, adding that decorator allows me to create URLs easily with <pk> within the URL. For example, I can send a POST request to http://main_url.com/do_something_to_user_with_id/7/, with do_something_to_user_with_id being some random function within the viewset and 7 being the user id/primary key. Is there any way I can do this with create? -

How do link a file user uploaded to Database?

Authentication problem while login with Custom User Model in Django
I created a custom user Model, that uses the Email field as the username. Also I had to create a Custom backend to validate as Case Insensitive the email field. The Registration page works perfectly fine, but when I try to login with a user that is not created I get this error: Environment: Request Method: POST Request URL: http://localhost:8000/members/login/ Django Version: 3.1.4 Python Version: 3.8.6 Installed Applications: ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'home', 'projects', 'about', 'blog', 'contact', 'members', 'ckeditor', 'django_bleach'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware'] Traceback (most recent call last): File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/DeveloperRoad/members/backends.py", line 14, in authenticate user = UserModel._default_manager.get(**{case_insensitive_user_name_field: username}) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/db/models/manager.py", line 85, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/db/models/query.py", line 429, in get raise self.model.DoesNotExist( During handling of the above exception (BlogUser matching query does not exist.), another exception occurred: File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/core/handlers/exception.py", line 47, in inner response = get_response(request) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/core/handlers/base.py", line 179, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/views/generic/base.py", line 70, in view return self.dispatch(request, *args, **kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/utils/decorators.py", line 43, in _wrapper return bound_method(*args, **kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/views/decorators/debug.py", line 89, in sensitive_post_parameters_wrapper return view(request, *args, **kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/utils/decorators.py", line 43, in _wrapper return bound_method(*args, **kwargs) File "/home/daniel/MEGA/my-git/github/Developer-Road-Website/Developer-road-website/venv/lib/python3.8/site-packages/django/utils/decorators.py", line … -
Delete User from db Django Rest_framework View function
I am pretty new to the django_restframework. I want to be able to delete users from the database when a DELETE request comes in. Here is my Views: class RetrieveUsersView(generics.ListCreateAPIView): """Retrieves all Users""" serializer_class = UserSerializer authentication_classes = (authentication.TokenAuthentication,) permission_classes = (permissions.IsAuthenticated,) queryset = get_user_model().objects.all() Here is my Serializer: class UserSerializer(serializers.ModelSerializer): """Serializer for the users object""" class Meta: model = get_user_model() fields = ('email', 'password', 'name') extra_kwargs = {'password': {'write_only': True, 'min_length': 5}} def create(self, validated_data): """Create a new user with encrypted password and return it""" return get_user_model().objects.create_user(**validated_data) def update(self, instance, validated_data): """Update a user, setting the password correctly and return it""" password = validated_data.pop('password', None) user = super().update(instance, validated_data) if password: user.set_password(password) user.save() return user Here is my Urls: urlpatterns = [ path('create/', views.CreateUserView.as_view(), name='create'), path('token/', views.CreateTokenView.as_view(), name='token'), path('me/', views.ManageUserView.as_view(), name='me'), path('all_users/', views.RetrieveUsersView.as_view(), name='all_users') ] From my understanding Django rest has built in classes that allow DELETE requests. However when I view the api on the local host I am only able to view all the registered users based on my RetrieveUsersView class. I would expect the url to be something like /api/users/all_users/1 Then delete that one. I am bit confused on how to get that functionality.
