Question

我正在尝试对搜索查询进行分页。所有进口似乎都在正确的位置，但它一直告诉我这个错误。 “pagination.PaginationSerializer未定义”。我不明白为什么？因为我从“rest_framework.pagination导入PaginationSerializer”导入它。这很奇怪，我确信我正在做一些没有以正确方式完成的事情。所以这是我的代码。

注意：我的代码基于官方文档中的示例。 http://www.django-rest-framework.org/api-guide/pagination#paginating-basic-data

这是我在浏览器中的TraceBack： http://dpaste.com/2R1F03X/

异常类型：/ user-search /

中的NameError

异常值：未定义名称“分页” 例外位置：/var/www/api/serializers.py in，第19行

class PaginatedUserSerializer(pagination.PaginationSerializer):

    class Meta:
        object_serializer_class = UserSearchSerializer

Answer 1

因为您将其导入为PaginationSerializer，所以前面不需要分页。改为：

class PaginatedUserSerializer(PaginationSerializer)

或者，您可以更改导入：

from rest_framework import pagination
