from rest_framework.viewsets import GenericViewSet
from rest_framework.mixins import ListModelMixin
根据源码写自己的分页
配置的分页类的对象调用了page = self.paginate_queryset(queryset)
paginate_queryset是GenericAPIView中的
---->>>paginate_queryset(queryset, self.request, view=self)
所以可以在自己写的视图类下 先实例化出一个对象 去调用paginate_queryset
如果返回值不为空则进行序列化
if page is not None:
# 把page进行了序列化
serializer = self.get_serializer(page, many=True)
# 实例化完之后调用get_paginated_response方法 继承的分页类中的方法
return self.get_paginated_response(serializer.data)
即--->>>
return Response(OrderedDict([
('count', self.page.paginator.count),
('next', self.get_next_link()),
('previous', self.get_previous_link()),
('results', data)
]))
