put() takes at least 3 arguments (2 given)

This is my code in Views.py

class NotificationsViewSet(viewsets.ModelViewSet):
    permission_classes = [permissions.IsAuthenticated, TokenHasReadWriteScope]
    queryset = Notifications.objects.all()
    serializer_class = NotificationsSerializer
    filter_fields = ('status','task','survey_type',)

    def put(self, request, pk, format=None):
        notifications = self.get_object(pk)
        serializer = NotificationsSerializer(notifications, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    def delete(self, request, pk, format=None):
        notifications = self.get_object(pk)
        notifications.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)

When i try to use method PUT i got error put() takes at least 3 arguments (2 given). What is wrong with my code?

That's probably because you're doing a PUT on the set entry point where the pk isn't defined. Make it optional:

def put(self, request, pk=None, format=None):

Note that there's no point in using viewset if you're overriding put.

def put(self, request, pk, format=None):

It takes 3 arguments at the minimum. Like:

self.put(request, pk)

self variable needs to be passed.

Alternatively,

put(self, request, pk)

Or 4 arguments at the max,

self.put(request, pk, format)
