Response has no attribute 'username'

I try to return a custom Response for my generics API view but it does not work since I get 'Response' object has no attribute 'username' error when the API is called

Here's what I've done so far:

I handle the DoesNotExist exception error then return a Response (from django rest framework).

class UniqueEmailAPI(generics.RetrieveAPIView):
  permission_classes = [
    permissions.AllowAny,
  ]

  serializer_class = UserSerializer

  def get_object(self):
    email = self.request.data['email']
    try:
      return User.objects.get(email= email)
    except ObjectDoesNotExist:
      return Response(status=status.HTTP_204_NO_CONTENT)

UserSerializer:

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email')

Exception Log: Stacktrace

Your serializer is trying to serialize your Response(status=status.HTTP_204_NO_CONTENT) response. It will try to serialize anything you return from get_object with your serializer unless you raise an error.

You can raise a 404 error using Django's get_object_or_404 method for the framework to know it should return an error response instead.

You could do something this:

from django.shortcuts import get_object_or_404
get_object_or_404(User, email= email)
