Can't get csrftoken in Django for ajax recently
I referenced the code provided in the official doc here https://docs.djangoproject.com/en/4.2/howto/csrf/#acquiring-the-token-if-csrf-use-sessions-and-csrf-cookie-httponly-are-false It worked well until recent. I didn't make any modification to the getCookie method. But it suddenly can't work on both Chrome and Firefox. The document.cookie always return "". And CSRF_USE_SESSIONS and CSRF_COOKIE_HTTPONLY are False. How sould I debug? I need the csrftoken to be passed to the ajax request. Thanks. Referenced src is here function getCookie(name) { let cookieValue = null; if (document.cookie && document.cookie !== '') { const cookies = document.cookie.split(';'); for (let i = 0; i < cookies.length; i++) { const cookie = cookies[i].trim(); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue;} const csrftoken = getCookie('csrftoken'); -

Django Pytest Failing In GitHub Workflow - How to mimic production environment?
I'm using GitHub Actions to create a CI/CD pipeline that tests production settings before deploying. The tests pass in my local environment, and all of the code works in production. However, any tests related to views fail in my GitHub workflow. I believe the tests are failing because GitHub's testserver defaults to http protocol, I assume.

How can I add a form to edit Comments to each Instance on a Django DetailView?
I am new to Django and trying to figure out how to build a webapp where I have Assets, attached Instances (of these Assets), and Comments attached to these instances, so basically in terms of simplified models.py models.py class Asset(models.Model) class Instance(models.Model): asset = models.ForeignKey(Asset, on_delete=models.CASCADE, related_name='instances') class Comment(models.Model): instance = models.ForeignKey(Instance, on_delete=models.CASCADE, related_name='comments') I know I will have to use forms based on the Instance class so I prepared this: forms.py class InstanceComment(ModelForm): class Meta: model = Instance fields = '__all__' I use the generic list view to display the list of Assets, when I click on one of them, I then display a list of the Instances attached to it using a Detail view. What I would like, is that on this page, have for each of the Instances, a form to edit the comment (there can be only one comment per Instance). I am struggling to see how to pass multiple forms to the view. I guess this is a very standard question with Django but I could not figure it out so far... Could I get any guidance on this? So far, I do not see how to effectively send a list of forms to the … -
Why am I getting a TypeError when passing HTTP method dictionaries to Django REST Framework's as_view() method in ViewSets?
I created a ViewSet, in which I need to use in two URL Patterns, one is for getting the list of items and other is for getting the detail of single item. The problem is, when I pass {"get": "retrieve"} and {"get": list", "post": "create"} dictionaries in as_view() methods of my ViewSets in URL Patterns, I get the following error: TypeError: APIView.as_view() takes 1 positional argument but 2 were given Below is my ViewSet code: class LungerItemViewSet(mixins.ListModelMixin, mixins.CreateModelMixin, mixins.RetrieveModelMixin, generics.GenericAPIView): permission_classes = [permissions.AllowAny,] def get_queryset(self): """Retrieves and returns all Lunger Items""" return LungerItem.objects.all() def get_serializer_class(self): """Returns serializer class""" return LungerItemSerializer and below are my URL Patterns for this ViewSet: urlpatterns = [ path('lungar-items/', views.LungerItemViewSet.as_view({'get': 'list', 'post': 'create'}), name='lunger-item-list'), path('lungar-items/<int:pk>/', views.LungerItemViewSet.as_view({'get': 'retrieve'}), name='lunger-item-detail'), ] I tried to search this issue on ChatGPT, but it did not help much. However, it helped me finding the cause of this error. As per ChatGPT and my own research this error appears, when: We use as_view instead of as_view(). Basicaaly as_view() is a method and we should treat it like that. We pass the HTTP Methods dictionary like {"get": "list"} in an APIView class instead of a ViewSet If there are any custom Middleware used … -

Why is 'b' being added to my Django app's varchar data after upgrading to Django 4.2?
I am migrating an application from Django1.11/Python2.7/Postgres9.2 to Django4.2/Python3.11/Postgres14.3 (FYI I am also migrating the data from postgres 9 to 14). I am running into an issue where I call a form where the varchar data that is displayed in my app gets a "b'" and "'" appended to the data displayed by the form. Example (John is now 'bJohn') and modifies the data in the postgres database by adding the "b'" and "'" to the data. I have tried to clean the data, removed migrations, dropped the database, etc. FYI when I type() the fields everything returns as type 'str', even after the b' is added to the data.

VSCode debugger in Django only hits once - on initial load
I am trying to make the debugger hit a breakpoint when Django handles a request. I set a breakpoint in a View and start the debugger in VSCode. The breakpoint get's hit when I start the app and continues when I press play. However, it never hit's the breakpoint again if I make requests to that view. It looks like the debugger works on load and then the code runs in the normal terminal and the debug console is just blank. So it seems like the code is not actually running inside the debugger. Any suggestions? { "version": "0.2.0", "configurations": [ { "name": "Python: Django", "type": "python", "request": "launch", "program": "${workspaceFolder}/src/python/.../manage.py", "args": [ "runserver", "--noreload", "--nothreading" ], "django": true, "justMyCode": true }, ] } # urls.py router.register("products", ProductViewSet) # products.py class ProductViewSet(viewsets.ReadOnlyModelViewSet): queryset = ... breakpoint() # Trying to hit a breakpoint here when a request is made serializer_class = ProductSerializer @extend_schema(request=None, responses=ProductPriceSerializer()) -
How can I ensure correct grouping in a Django subquery annotation?
When I'm writing Django Subquery expressions, sometimes I have no idea how Django is going to group the result. Example: subquery = ( RelatedModel.objects.filter( category="some_category", grandparentmodel=OuterRef("relatedmodel__grandparentmodel"), mymodel__created_at__date=OuterRef("created_at__date"), ) .values("grandparentmodel", "mymodel__created_at__date") .annotate(net=Sum("mymodel__amount")) .values("net")[:1] ) query = ( MyModel.objects.annotate( net=Coalesce( Subquery(subquery), Decimal("0.00") ) ) ) With this, my goal is to group a bunch of ParentModel instances (with category "some_category") by grandparentmodel and mymodel__created_at__date. This seems to work only if I include the .values("mymodel__created_at__date") before my annotation. If I do not include that before my annotation of net, the subquery still runs and just gives incorrect net. However, the .values("grandparentmodel") seems not required to get the correct grouping; I can exclude it and I still get the values I'm expecting. What's going on behind the scenes? How would I know to use a .values() call before my annotation to group correctly? How would I know what to include in said values() call? Is there some rule of thumb to follow when aggregating in subqueries? -
How to fix this issue in django & mysql It is impossible to change a nullable field 'description' on item to non-nullable without providing a default
i am having this problem where when i try to make migrations in python it shows this error -> It is impossible to change a nullable field 'description' on item to non-nullable without providing a default. This is because the database needs something to populate existing rows. Please select a fix: Provide a one-off default now (will be set on all existing rows with a null value for this column) Ignore for now. Existing rows that contain NULL values will have to be handled manually, for example with a RunPython or RunSQL operation. Quit and manually define a default value in models.py. Select an option: -
