Django DRF view AttributeError-CodePudding

I'm trying to get data that is related to the request.user but i'm doing something wrong.

serializers.py

class SchoolSerializerList(serializers.ModelSerializer):
     class Meta:
           model = School
           fields = ('name', 'zone', 'city', 'subCity', 'abbr',
                     'woreda', 'Schooltype', 'schoolemail', 'schoolphone', 'created_date')

views.py

 class MySchoolsView(generics.ListAPIView):
    permission_classes = [IsSchoolOwner, ]
    serializer_class = SchoolSerializerList

    def get_queryset(request):
        try:
            queryset = School.objects.filter(owner=request.user)
        except ObjectDoesNotExist:
            return Response({"error": "Nothing found."})
        return queryset

the owner field in the school model is a foreignkey to the user i wanted to check if the current user has any schools by trying to match request.user with School.owner but this returns an attribute error saying

'MySchoolsView' object has no attribute 'user'

CodePudding user response：

The first and only parameter of get_queryset is self, not request. You can access the request object with self.ruquest, so:

class MySchoolsView(generics.ListAPIView):
    permission_classes = [IsSchoolOwner, ]
    serializer_class = SchoolSerializerList

    def get_queryset(self):
        return School.objects.filter(owner=self.request.user)

Your get_queryset can also not return a Response. You can raise a Http404 error:

from django.http import Http404

class MySchoolsView(generics.ListAPIView):
    permission_classes = [IsSchoolOwner, ]
    serializer_class = SchoolSerializerList

    def get_queryset(self):
        qs = School.objects.filter(owner=self.request.user)
        if not qs:
            raise Http404('No schools found')
        return qs
