如何在非通用视图/视图集中使用分页？

我们可以找到解决方案而无需重新发明轮子：

1. 让我们看一下如何实现

   generics

   分页： django-rest-framework / rest_framework / generics.py。
   这也正是我们将要使用的观点！
   

2. 假设我们有一个全局分页设置，如下所示
   

   settings.py

   ：

   REST_frameWORK = {'DEFAULT_PAGINATION_CLASS':     'rest_framework.pagination.DESIRED_PAGINATION_STYLE','PAGE_SIZE': 100

   }

3. 为了不使视图/视图集的代码膨胀，我们可以创建一个自定义的mixin来存储我们的分页代码：

   class MyPaginationMixin(object):@propertydef paginator(self):    """    The paginator instance associated with the view, or `None`.    """     if not hasattr(self, '_paginator'):         if self.pagination_class is None:  self._paginator = None         else:  self._paginator = self.pagination_class()     return self._paginator def paginate_queryset(self, queryset):     """     Return a single page of results, or `None` if pagination      is disabled.     """     if self.paginator is None:         return None     return self.paginator.paginate_queryset(         queryset, self.request, view=self) def get_paginated_response(self, data):     """     Return a paginated style `Response` object for the given      output data.     """     assert self.paginator is not None     return self.paginator.get_paginated_response(data)

4. 然后

   views.py

   ：

   from rest_framework.settings import api_settings

   from rest_framework.views import APIView

   from my_app.mixins import MyPaginationMixin

   class MyView(APIView, MyPaginationMixin):
   queryset = OurModel.objects.all()
   serializer_class = OurModelSerializer
   pagination_class = api_settings.DEFAULT_PAGINATION_CLASS

   # We need to override the get method to insert paginationdef get(self, request):    ...    page = self.paginate_queryset(self.queryset)    if page is not None:        serializer = self.serializer_class(page, many=True)        return self.get_paginated_response(serializer.data)

现在我们有了

APIView
