DRF 子视图快速实现功能的使用方法！

1,ListAPIView继承与GenericAPIView、ListModelMixin

# 对list重写，因为默认只会返回 serializer.data
    def list(self, request, *args, **kwargs):
        queryset = self.get_queryset()
        serializer = self.get_serializer(queryset, many=True)
        user = self.request.user

        return Response({
            'user_id': user.id,
            'default_address_id': user.default_address_id,
            'limit': 10,
            'addresses': serializer.data,
        })

2,DestroyAPIView继承了GenericAPIView、DestoryModelMixin

#对自带的进行重写,默认会直接删除掉
def delete(self, request, *args, **kwargs):
        # 如果有 pk 值那么就会按照pk值进行查找！
        address = self.get_object()
        # 进行逻辑删除
        address.is_deleted = True
        address.save()

        return Response(status=status.HTTP_204_NO_CONTENT)
