python - lookup_field 在 Django get_queryset 中返回 None

Question

我有一个用 GenericAPIView 扩展的类，

我可以在我的函数中访问查找字段，但我不能在查询集函数中使用它。

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

如何访问 get_queryset 中的 lookup_field？

Answer 1

我找到了答案:

从类中删除这一行:

lookup_field = 'phone_number'

在get_queryset中获取lookup_field，像这样:

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