How to properly use django testcase's addCleanup method?
I have a test subclass of APITestCase where I'm using the class-method setUpTestData to create data for my tests and also some mocks. Basically what I want to do is to run mock.patch.stopall (as shown next), but it's not working. I have based my implementation on THIS ANSWER and I'm using: Django v2.2.4 and djangorestframework v3.10.2 import mock from rest_framework.test import APITestCase class FooTest(APITestCase): @classmethod def setUpTestData(cls): patcher_one = mock.patch('route.one') mock_route_one = patcher_one.start() patcher_two = mock.patch('route.two') mock_route_one = patcher_two.start() cls.addCleanup(mock.patch.stopall) # etc super(FooTest, cls).setUpTestData() When running my tests with this code, I get: TypeError: addCleanup() missing 1 required positional argument: 'function' So I edit the addCleanup call to: cls.addCleanup(function=mock.patch.stopall) but I get the following: TypeError: addCleanup() missing 1 required positional argument: 'self' Editing to: cls.addCleanup(cls, function=mock.patch.stopall) I get AttributeError: type object 'FooTest' has no attribute '_cleanups' At this point I'm a bit lost. The workaround that I'm using is to do it in the tearDownClass method: @classmethod def tearDownClass(cls): mock.patch.stopall() But I would like to centralize all the testing logic in the setUpTestData method. Anyone see's where I'm messing up? -

Django how to pass header on request in get_queryset
I am using Django rest framework to pass a get request with a query_param like so: views.py class PlanView(generics.ListAPIView): """ API endpoint which allows prices to be viewed or edited """ serializer_class = PlanSerializer permission_classes = (IsAuthenticated,) # override method def get_queryset(self): queryset = Plan.objects.all() size = self.request.query_params.get("size", None) if portion is not None: if size == "large": queryset = queryset.filter(Large=True) elif size == "small": queryset = queryset.filter(Small=False) return queryset however, I set up an authentication class in settings.py like this: 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication' ] so that I can pass a header with a token in request. This works well when I test with a third party client like postman. however how can I pass a header in the above view? -

How to construct url path with two detailview
I have following url patterns urlpatterns = [ path('', CategoryListView.as_view(), name='forum'), path('category/<int:pk>/', CategoryDetailView.as_view(), name='forum-detail'), ] Inside the CategoryDetailView I will list the posts related to that category. So, when I click the any of the post I want the post detail view inside the category, because when I will create post with CreateView class I want category already predefined. I could also do the following path('post/<int:pk>/', ForumPostDetailView.as_view(), name='forum-post-detail'), path('post/new/', ForumPostCreateView.as_view(), name='forum-post-create'), ] In this case user should choose the category by himself when he or she will try create the post. But I want the category to be chosen already something like this ( I know this is wrong) path('category/<int:pk>/post/<int:pk>/', ForumPostDetailView.as_view(), name='forum-post-detail'), path('category/<int:pk>/post/new/', ForumPostCreateView.as_view(), name='forum-post-create'), ] So how to do it? -
How to allow access to base without permissions in django
How can I allow access to the base route while I have my Default permission classes set to IsAuthenticated in the global settings. REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly', # 'rest_framework.permissions.AllowAny', 'rest_framework.permissions.IsAuthenticated', ], } I know you can just set permission_classes = [AllowAny] in the individual views. But I want my base route to have the same i.e no permissions. Here is how i have the routes set in urls.py router_public = DefaultRouter() ''' PUBLIC ROUTES HERE ''' router_public.register( r'cars', car_viewset.Car_Public_Viewset, base_name='Cars') router_public.register( r'planes', plane_views.Plane_Public_ViewSet, base_name='Planes') urlpatterns = [ path('admin/', admin.site.urls), path('api/admin/', include(router_admin.urls)), path('api/public/', include(router_public.urls)), ] Since I have set permission_classes for cars and planes to AllowAny in the vews, I can access them without Authentication. How can I do the same for the base route http://localhost:8000/api/public/ since there's no view associated with it. -

What is causing this error in Django: NOT NULL constraint failed: mainapp_comment.post_id
I am in the middle of making a social network web application in Django. I have nailed most of the features needed, but I am stuck on making the commenting system work. I originally had it so users could make their own name for comments, but decided against that. The posting system has it, so the user who is logged in and makes the post, their name will be displayed for the author of the post. That's why some of the code is copy-pasted between the 2. I have tried all kinds of things, such as making the view a class instead of a function. It didn't work, and I am back to square one. Right now the user can make a post no problem, however the user's name isn't recorded and I have to set the author manually in the admin interface. The relevant code in views.py class CreatePostView(LoginRequiredMixin,CreateView): login_url = '/login/' redirect_field_name = 'mainapp/post_details.html' form_class = PostForm model = Post def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) @login_required def add_comment_to_post(request,pk): post = get_object_or_404(Post,pk=pk) if request.method == 'POST': form = CommentForm(request.POST) if form.is_valid(): comment = form.save(commit=False) comment.post = post comment.save() return redirect('mainapp:post_detail',pk=post.pk) def form_valid(self, form): form.instance.author = self.request.user … -
