【问题描述】：

在 DRF 3.1 中，我可以这样做以获得分页响应，但似乎 get_paginated_response() 在 3.0 中不可用。什么是等价物？

class NoteList(ListCreateAPIView):

    def list(self, request, *args, **kwargs):
        queryset = self.get_queryset()
        paged_queryset = self.paginate_queryset(queryset)
        serializer = NoteSerializer(paged_queryset, many=True)
        return self.get_paginated_response(serializer.data)

【解决方案1】：

是PaginationSerializer，通过以下方式设置序列化程序类：

'DEFAULT_PAGINATION_SERIALIZER_CLASS'：'YourCustomPaginationSerializer'

或

class MyView(generics.GenericAPIView):
    pagination_serializer_class = YourCustomPaginationSerializerClass

mixin.py

def list(self, request, *args, **kwargs):
    instance = self.filter_queryset(self.get_queryset())
    page = self.paginate_queryset(instance)
    if page is not None:
        serializer = self.get_pagination_serializer(page)
    else:
        serializer = self.get_serializer(instance, many=True)
    return Response(serializer.data)

generics.py

def get_pagination_serializer(self, page):
    """
    Return a serializer instance to use with paginated data.
    """
    class SerializerClass(self.pagination_serializer_class):
        class Meta:
            object_serializer_class = self.get_serializer_class()

    pagination_serializer_class = SerializerClass
    context = self.get_serializer_context()
    return pagination_serializer_class(instance=page, context=context)

如果你在做migration 的东西，别忘了settings.py 或View 中的分页参数，已经改成新的分页器了。

比如。 PAGINATE_BY_PARAM -> page_size_query_param。

无论如何，我认为新的分页器比以前的更舒适。在Pagination Docs上查看更多详情
