lookup_field Return None In Django get_queryset

Question

I have a class extend with GenericAPIView ,

I Can access to the lookup_field in my functions, but I can't use it in the queryset function.

class SellerItemAPIView(GenericAPIView, ListModelMixin):
    serializer_class = ShopItemSerializer
    permission_classes = [AllowAny]
    lookup_field = 'phone_number'

    def get_queryset(self):
        print(self.lookup_url_kwarg) # It Return None
        print(self.lookup_field) # It Return 'phone_number'
        shop_items = ShopItem.objects.filter(Q(seller_id__user_id__phone_number=self.lookup_field))
        return shop_items


    def get(self, request, phone_number):
        result = self.list(request, phone_number)
        print(result.status_code)
        return result

How Can I Access to the lookup_field in get_queryset ?

Answer 1

I found the answer:

Remove this line from class:

lookup_field = 'phone_number'

Get the lookup_field in get_queryset, like this:

phone_number = self.kwargs.get('phone_number')
