Update a field for all instances when a Many-to-many relationship is involved
I have the following: class Customer(model): stores = models.ManyToManyField(Store, related_name = "customers") subscriptions = models.ManyToManyField(Subscription, through = "CustomerSubscription") class CustomerSubscription(model): subscription = models.ForeignKey(Subscription) customer = models.ForeignKey(Customer) class Subscription(model): is_valid = models.BooleanField() For a given store instance: store = Store.objects.get(pk=1) I want to get all the subscriptions for all the customers and set is_valid to False. This is my attempt which appears to work: customers = store.customers.all() for c in customers: c.subscriptions.update(is_valid=False) I then tried using prefect_related: customers = store.customers.prefect_related("subscriptions") for c in customers: c.subscriptions.update(is_valid=False) But I don't believe I am doing this correctly as it resulted in more sql queries than my first attempt. How should I be doing this? -

postgresql - cannot modify default "postgres" user
How to change, alter, postgres default values for my project? I have a django project which I try to deploy to digital ocean on an ubunto instance. In psql I create a new user with new_password and grant it all privileges to the new_db. Yet, these created entries are not connected to my project database. i.e. The values of the databases remain the default ones: Name/User/Password=postgres I note here the commands I run the Docean, ubuntu server: Assunming a new_user created (i.e. none root) and all psql packages are installed. sudo -u postgres psql CREATE DATABASE new_db; #DATABASE created; CREATE USER new_user WITH PASSWORD 'new_psw'; ALTER ROLE new_user SET client_encoding TO 'utf8'; ALTER ROLE new_user SET default_transaction_isolation TO 'read committed'; ALTER ROLE new_user SET timezone TO 'UTC'; GRANT ALL PRIVILEGES ON DATABASE new_db TO new_user; Quitting postgres, I my database value on my shell: The values remain the default ones: DATABASES {‘default’: {‘ENGINE’: ‘django.db.backends.postgresql’, ‘NAME’: ‘postgres’, ‘USER’: ‘postgres’, ‘PASSWORD’: ‘postgres’, ‘HOST’: ‘localhost’, ‘PORT’: 5432, ‘ATOMIC_REQUESTS’: False, ‘AUTOCOMMIT’: True, ‘CONN_MAX_AGE’: 0, ‘CONN_HEALTH_CHECKS’: False, ‘OPTIONS’: {}, ‘TIME_ZONE’: None, ‘TEST’: {‘CHARSET’: None, ‘COLLATION’: None, ‘MIGRATE’: True, ‘MIRROR’: None, ‘NAME’: None}}} I also tried the following: I then declared the new_user as the database … -
Django OneToOne field where one side of the relation is mandatory
Suppose I have these models: class Space(models.Model): item = models.OneToOneField(Item, null=True, on_delete=models.CASCADE) class Item(models.model): ... A Space can contain an Item, but it can be empty too. On the other hand, every Item must have a Space. It cannot exist in a void. I could create a field .space in my Item model (with null=False), but then Space.container can never be empty (raising a RelatedObjectDoesNotExist exception when creating/querying them). Handling these exceptions is cumbersome. I'd rather have Space.container return None (as is the case with my current setup). Is there an easy way to make .space in the Item model mandatory, but not the other way around? -
How to set the redirect URL in Django within the dispatch method with URL parameters
I have a custom Mixin that checks for the total usage of a particular service and based on that allows users to submit the form or redirect to the success_url with an error message of total usage. This works fine for URLs without any dynamic parameters like pk or slug. but with parameters, Django cannot find a URL pattern to redirect to the success_url. urls.py (URL file of Instagram app) # some other urls path('<int:post_id>/image/stock/', InstagramImageStockView.as_view() , name='instagram_image_stock'), path('<int:post_id>/image/stock/generate/', InstagramGenerateStockImageView.as_view(), name='instagram_fetch_stock_image'), # more URLs views.py class InstagramGenerateStockImageView(CustomMixin, FormView): form_class = InstagramStockImageForm success_url = 'instagram:instagram_image_stock' # other code custom mixin class CustomMixin: # other methods def check_generation_status_and_redirect(self, request, *args, **kwargs): if self.able_to_generate: return super().dispatch(request, *args, **kwargs) else: # Set an error message based on conditions. return redirect(self.success_url, kwargs=kwargs) def dispatch(self, request, *args, **kwargs): self.check_daily_count() return self.check_generation_status_and_redirect(request, *args, **kwargs) When a user reaches the limit I am getting NoReverseMatch error while redirecting to the success_url. I also tried by defining the success_url with reverse_lazy but not working. Thanks. -
how can I determine which ORM is the most suitable for my specific Django project requirements?
What are the factors to consider when choosing an ORM for a Django project, and how can I determine which ORM is the most suitable for my specific project requirements? I'm currently working on a new project and I'm looking for advice on the best ORM to use that doesn't require migration. I prefer to work with ORMs that simplify database interactions and reduce the amount of boilerplate code that I have to write. However, I've run into issues with ORMs that require migration for database schema changes. I'm hoping that some of you may have experience with ORMs that don't require migration and can offer recommendations. I'm particularly interested in ORMs that have a robust set of features, good documentation and are easy to use. Any suggestions would be greatly appreciated. Thank you in advance! -

Uploading to MEDIA_URL instead of referencing static image
I have some default images stored in my static folder that we use for migrations. I reference these when deploying new features in order to batch create a large number of icons: # Set Icon icon_path = finders.find(my_path) if icon_path: icon_file = open(icon_path, "rb") icon = File(icon_file) else: raise Exception("Icon file not found.") obj.icon = icon One thing I've noticed with this method is that the saved icon references the static folder URL instead of referencing my S3 MEDIA_URL (configured with django-storages). I'm wondering if there's something I'm missing that could be causing this to happen, because when I upload an image and set it the same way from a DRF serializer it goes to S3 instead. -
Using TailwindCSS in a Django project hosted on Github
I want to use Django together with TailwindCSS in a personal web project and followed two instructions for setting it all up: on the one hand the installation instructions on https://tailwindcss.com/docs/installation on the other hand this Youtube tutorial (because the installation guide was too short for my limited understanding of the topic). https://www.youtube.com/watch?v=lsQVukhwpqQ Since I am not familiar with node.js and npm, i am unsure how to store the resulting project in Github and reproduce it on other computers. The structure of the Django project is no problem, I am familiar with it. I am unsure about the files and folders related to Tailwind and Node. After the tutorial I had a "node_modules" and a "local-cdn" folder as well as "package.json" and "package-lock.json" and a "tailwind.config.js". My question would be: which files present at the end of the two tutorials above should be synced with Github, which should not be synced and what to set up on a second machine (beyond installing node and django obvsly) to continue working on this already existing project there (in contrast to the tutorials above describing how to start a new project)? -

Django : best place to store constants used in view and Celery tasks
I'm looking for advice regarding project structure in my Django app. I want to define a constant that is used both in a view and in a background task (Celery to be specific), but I am not sure where this should be placed. The constant defines the number of records to be shown to the user. My model represents an image, and only the recent 100 records need to be displayed on the page. Older records can be deleted, and there is a separate Celery task that cleans up such records on a weekly basis. I have defined this 100 as NUM_RECORDS_TO_SHOW in my model class, but I am not sure if this is the best place, since I am exposing my model to the business logic. Defining this constant in my view seems also a bad idea, as this could lead to circular imports. -

Overriding the default validation for a Django admin Foreign Key field
I have Django models that inherit from an Archive class in which the default manager (objects) is replaced with a query that does not return archived records. This works well throughout the system. However, in admin, when a record with a foreign key attempts to validate and that foreign key instance is an archived record, the validation attempts to use the new default manager, objects which filters out archived records as opposed to the objects_all manager which returns all records - and since an archived record is not returned using objects, the save fails with "instance does not exist". Here is a simplified example: class Inv(AbstractArchive): item_code = models.CharField(max_length=20, primary_key=True) qty = models.IntegerField() def __str__(self): return f"{self.item_code}" class Txn(AbstractArchive): inv = models.ForeignKey(Inv) date = models.DateField() added = models.IntegerField My admin for Txn looks like this (I defined a form in admin with a queryset that gets all the records, even those marked as archived - I also included a clean method hoping this would override the form's default validation that uses the objects manager) class TxnForm(forms.ModelForm): class Meta: model=Txn def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['inv'].queryset = Inv.objects_all.all() def clean_inv(self): inv= self.cleaned_data['inv'] if not Inv.objects_all.filter(inv=inv).exists(): raise forms.ValidationError("Invalid inventory record selected.") … -
How to update m2m objects with django formsets?
I'm starting this project in which I have an Order class with an m2m relationship with an Item class using the throug argument with an ItemTimes class.

Django unable to submit form, getting error 'Select a valid choice. That choice is not one of the available choices'

Django Serializer to group fields
I want to build a simple endpoint /users/ that returns output like the following: { ids: [ "e3fa5cbe-e89e-4017-bbd3-546019247932", "94c1f979-f122-471b-a694-e748f5d95c25", "30f20792-18d9-4db0-8dde-9ad62d239928", "2ee0399d-881a-43b5-ad53-a741507e12c1", "359b6550-bcfd-4c41-99be-3422cbba3da5" ] } The id's belong to the user objects themselves. I have a model viewset defined as such: class UserIdViewSet( viewsets.ModelViewSet, mixins.ListModelMixin, ): queryset = User.objects.all() permission_classes = [IsAdmin] serializer_class = IdListSerializer filterset_class = UserFilter def get_queryset(self): return User.objects.filter( company=self.request.user.get_company() ) But I am having difficulty writing IdListSerializer. ChatGPT and Copilot suggest variations of the following: class IdListSerializer(serializers.Serializer): ids = serializers.ListField(child=serializers.UUIDField()) def to_representation(self, instance): return {"ids": [str(user.id) for user in self.objects.all()]} But instance is not itterable.

Django Custom API Endpoint with two parameters
I want to build a fairly simple API endpoint in a Django app I inherited. I'm new to python and Django The app uses views.py with classes that extend ModelViewSet. It also uses a urls.py with entries like this: router.register('agent_licenses', views.AgentLicenseViewSet) and this one I came up with: router.register(r'agent_licenses/(?P<agent_id>\d+)/<state_id>\d+/', views.AgentLicenseViewSet) I need to build the fastest-responding endpoint possible and so I plan to use a custom SQL query that returns a True/False. Is there some straightforward way to build an endpoint (hopefully in views.py, although if that's not possible, that's ok.) that will show up in Swagger without having to wrestle with Models, ModelViewSet, urls.py, Serializers, etc? I have managed to get close, using the AgentLicenseViewSet, like this: (Ignore the actual code in the endpoint method - it's just test code at this point) class AgentLicenseViewSet(viewsets.ModelViewSet): """Agent license REST view """ queryset = models.AgentLicense.objects.all() serializer_class = serializers.AgentLicenseSerializer filter_backends = (django_filters.DjangoFilterBackend,) filterset_class = filters.AgentLicenseFilter @action(methods=["GET"], detail=True) # def has_license_in_state(self, agent_id: int, state_id: int) -> Response: def has_license_in_state(self, *_args, **_kwargs ) -> Response: #print(state_id) #print(pk) # return Response(data={'message': False}) return Response(data=False) # return False But - when I run this, I get an endpoint that appears to be ignoring the \d+ in … -
