Getting Error In Swagger(drf_yasg library) For Nested Serializers in Django
I'm using drf_yasg library in django. Normally everything was working correctly. When I use the nested serializer, I get the following error in the swagger interface. **Error: ** Internal Server Error: /swagger/ Traceback (most recent call last): File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) ^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\django\core\handlers\base.py", line 181, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\django\views\decorators\csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\django\views\generic\base.py", line 70, in view return self.dispatch(request, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\rest_framework\views.py", line 509, in dispatch response = self.handle_exception(exc) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\rest_framework\views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\rest_framework\views.py", line 480, in raise_uncaught_exception raise exc File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\rest_framework\views.py", line 506, in dispatch response = handler(request, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\views.py", line 94, in get schema = generator.get_schema(request, self.public) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\generators.py", line 246, in get_schema paths, prefix = self.get_paths(endpoints, components, request, public) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\generators.py", line 404, in get_paths operation = self.get_operation(view, path, prefix, method, components, request) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\generators.py", line 446, in get_operation operation = view_inspector.get_operation(operation_keys) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\inspectors\view.py", line 32, in get_operation body = self.get_request_body_parameters(consumes) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\inspectors\view.py", line 82, in get_request_body_parameters return self.get_request_form_parameters(serializer) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\inspectors\view.py", line 134, in get_request_form_parameters return self.serializer_to_parameters(serializer, in_=openapi.IN_FORM) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\userx1\OneDrive\Desktop\projectx_backend\venv\Lib\site-packages\drf_yasg\inspectors\base.py", line 448, … -
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? -

django login url with param
a third party authentication requires api must be called in the index view, for example my domain is zzd.com, then they only provide api to zzd.com, which means we cannot have route specified for a signin view, which unable to put all login stuff into zzd.com/login/ however, index view is designed to shows some other important info primarily rather than login QR, which only contains a login button, to use js to display the QR when click. here's the issue, I have followed declared in settings.py: my index view serves all stuff in one template, including trending info, and login qr code if user is not auth-ed. javascript looks like this: const url = new window.URL(window.location.href); let mode = url.searchParams.get('mode'); if(mode === 'login'){ showLoginQrCodeScanner(); } which login qr img would only show if index/?mode=login specified, otherwise would display trending info instead. and my settings.py: LOGIN_REDIRECT_URL = 'index' LOGIN_URL = 'index' the issue is that, I have some of my views @login_required, but, an anonymous user, would get redirected to the index/?next=particular/url, without the mode=login part, which does not show the qr primarily. is there a way to declare login url with the param, for a much better user experience? -

Integrating tailwindcss with django
am trying to integrate tailwindcss with django. django seems to have located my tailwindcss and even the default font for tailwindcss is implemented, but none of the tailwind classes seems to work in my project. What could be the reason why? I tried passing classes mx-auto, font-semibold into my div as seen in this image but both the classes failed to respond as seen in this image. And when i tried to add another css property (background-color:blue) in the tailwind output file, that property works. So the question is, how comes other css properties work but tailwind classes won work for me? -

drf custom authentication backend gets executed on the path that doesn't need authentication
I am new to django and I am trying to add permissions from DRF to my project. Ever since I have set DEFAULT_AUTHENTICATION_CLASSES for REST_FRAMEWORK in django settings.py, all the requests are going to the authenticate method of my DEFAULT_AUTHENTICATION_CLASSES irrespective of what permission I set to my view. Later it is coming to my view. So here is the settings I have added: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'authentication.customauth.CustomAuthBackend', ] } And here is my authentication.customauth.CustomAuthBackend: class CustomAuthBackend(BaseAuthentication): def authenticate(self, request): user = AuthUtils.get_user_from_token(request) if user is None: raise AuthenticationFailed('User not found') request.user = user return user, None @staticmethod def authenticate_with_password(request): email = request.data.get('email') role = "CONSUMER" if request.data.get('role') is None else request.data.get('role') password = request.data.get('password') user = User.objects.filter(email=email, role=role).first() if password is not None and user is not None and user.check_password(password): return user The views that actually should be called without authentication have @permission_classes([AllowAny]) permission. Say this login view: @api_view(['POST']) @permission_classes([AllowAny]) def login(request): user = request.user if user and user.is_active: serializer = UserSerializer(user) tokens_map = AuthUtils.generate_token(request=request, user=user) return Response({'success': True, 'user': serializer.data, 'tokens': tokens_map}) return Response(data={'success': False, 'message': 'User not found'}, status=status.HTTP_404_NOT_FOUND) With my understanding I think if permission class is rest_framework.permissions.AllowAny no authenticate method should not be … -

Should I make redirect-urls creating API service with Django Rest Framework?
I am new to web-development and creating APIs, so I have some misunderstandings. I am creating online-shop API, and already have registration system with email confirmation. So the logic is: When user sends post request to registration endpoint he recieves an url that consists of token and his ID, at the same time his account is created, but is_active status equals False. When he requests the page with the url, his is_active=True. So, according to business-logic of my web-app, when user requests the page with the given url to confirm email, he is supposed to automatically login and be redirected to his personal profile endpoint. My question is: should I make redirections in DRF using redirect and reverse functions, or it is a task for fronted developers? Sorry if question seems to be silly, I am just learning. Thanks in advance Just want to clarify my mind, if it is ok to make redirects in backend development, or it is supposed to be done by frontend developers. -

Improve Django filter preformance for all fields searching special ManyToMany

Integration Testing In Django Involving Reverse Lambda Call
I need to test a django application which involves AWS lambda talking back to the django server. Mock testing does not help catching the bug, so I need the original lambda function to be part of the test. The Django TestCase creates a temporary database for testing apart from the production database, which is good. However, when lambda function calls back to the server, it is outside of the context of the TestCase and therefore it refers to the production database instead of the test database and the test fails to complete. Is there any way to override the django settings globally to use the test database during the integration test? I tried to override the settings of the TestCase, but it does not apply globally, rather it is just for the TestCase. -

I have a /users route in my app which is initialized with a default router like this : (Note that responses and dependencies have been removed from the snippet to protect proprietary code) api_router = APIRouter( responses={}, route_class=LocalizationRoute, dependencies=[], ) Localization Route is being used directly from fastapi-localizationpackage for translation purpose. Now I want to add another router to the same route for the purpose of logging . This router is based on the following router class def log_info(req_body, res_body): print(req_body) print(res_body) class LoggingRoute(APIRoute): def get_route_handler(self) -> Callable: original_route_handler = super().get_route_handler() async def custom_route_handler(request: Request) -> Response: req_body = await request.body() response = await original_route_handler(request) if isinstance(response, StreamingResponse): res_body = b'' async for item in response.body_iterator: res_body += item task = BackgroundTask(log_info, req_body, res_body) return Response(content=res_body, status_code=response.status_code, headers=dict(response.headers), media_type=response.media_type, background=task) else: res_body = response.body response.background = BackgroundTask(log_info, req_body, res_body) return response return custom_route_handler I tried doing this by using includerouter clause like this : api_router.include_router(APIRouter(router_class= LoggingRoute)) But this is not working. I can see the router class is still set to Localization Route and the routerclass argument in include_router statement is ignored. So I was wondering do fast api not support adding multiple routers with different router class to the …
