Updating duplicate student Information in django
I have a bunch of CSV files that I have made to upload to a django model. 1. Created a view to upload the csv 2. Separated the fields and added them to a variable 3. Called the update_or_create() method to add the information into the model. The problem that I am facing is getting django to update the old row instead of creating a new one. If a student has failed in the first year but passes the next year, the old marks have to be updated. I am trying to filter() with the Register Number of the student and Class to narrow it down. IF there is a student with for instance AAAAAA1111 from BA 1 SEM, and they gave the exam in 2016, 2017 and passed in 2018, the last result has to update the old result. I am enclosing two documents which i used. One is the 2016 result and the second is the 2017 repeaters csv.

How to access the field value before serialization in my serializer (serializers.Serializer) or rest view (UpdateAPIView)? I have something like this: class MySerializer(serializers.Serializer): my_field = serializers.IntegerField() If I try to fill my field with 'test' string, it will immediately raise the ValidationError telling me about wrong data type (expecting an integer number of course). Before that error raise, I want to capture the value and do something with it but I have no idea how and where can I access it. It has an empty string value everywhere. I tried to get it in is_valid() before call super() or with raise_exception=False, but I still can not see it: '_kwargs': {'context': {'format': None, 'request': <rest_framework.request.Request object>, 'view': <rest.views.MyUpdateAPIView object>}, 'data': <QueryDict: {'my_field': ['']}>, 'initial_data': <QueryDict: {'my_field': ['']}>, When I try to find it in my view I can also see nothing: serializer.initial_data <QueryDict: {'my_field': ['']}> request.data <QueryDict: {'my_field': ['']}> When I try to check validate() or validate_my_field() methods, I can not even get there because of the ValidationError I mentioned above. How the serializer validation actually works? What is the order in it and how can I access data before it is "cleaned"? -
Authentication in Django Channels v2 tests with WebSocketCommunicator
In the process of writing tests for my chat consumer I encountered with a problem of being unable to authenticate in tests, using WebSocketCommunicator. I have custom JwtTokenAuthMiddleware that implements authentication in sockets by using token in request query, because as I know, decent authentication with the use of authorization headers is not possible yet. Can you guys advise me on that or provide me with the example code, which I couldn't find across the net ? Btw, my chat is working without problems. Also tests should be perfectly fine, I took the guide from official documentation Django Channels 2.x Testing. --JwtTokenAuthMiddlewate-- class JwtTokenAuthMiddleware: def __init__(self, inner): self.inner = inner def __call__(self, scope): close_old_connections() try: raw_token = scope['query_string'].decode().split('=')[1] auth = JWTAuthentication() validated_token = auth.get_validated_token(raw_token) user = auth.get_user(validated_token) scope['user'] = user except (IndexError, InvalidToken, AuthenticationFailed): scope['user'] = AnonymousUser() return self.inner(scope) JwtTokenAuthMiddlewareStack = lambda inner: JwtTokenAuthMiddleware(AuthMiddlewareStack(inner)) --Example Test-- @pytest.mark.django_db(transaction=True) @pytest.mark.asyncio async def test_trainer_auth_success(): room = await database_sync_to_async(RoomFactory.create)() trainer = room.trainer trainer_token = await sync_to_async(get_token_for_user)(trainer.user) room_url = f'ws/room/{room.id}/' trainer_communicator = WebsocketCommunicator(application, f'{room_url}?t={trainer_token}') connected, _ = await trainer_communicator.connect() assert connected trainer_connect_resp = await trainer_communicator.receive_json_from() assert_connection(trainer_connect_resp, [], room.max_round_time) await trainer_communicator.disconnect() --Traceback of Error-- ___________________________________________________________ test_trainer_auth_success ___________________________________________________________ self = <channels.testing.websocket.WebsocketCommunicator object at 0x7f6b9906f290>, timeout = 1 …
