Django Rest Framework - APIView 分页

Question

我有一个非常简单的 APIView ，但我不知道如何在这里设置分页。 In this scenario I select an Event with given pk , then I get all the NewsItems assigned to this Event .

pagination_class = LimitOffsetPagination 当我在开头定义查询集时工作正常 ListCreateAPIView 例如。 queryset = Event.objects.all() 但不是自定义 get ：

 class EventNewsItems(APIView):
    pagination_class = LimitOffsetPagination

    def get(self, request, pk, format=None):

        #user = request.user
        event = Event.objects.get(pk=pk)
        news = event.get_news_items().all()

        serializer = NewsItemSerializer(news, many=True, context={'request':request})
        response = Response(serializer.data, status=status.HTTP_200_OK)
        return response

---

解决了：

 def get(self, request, pk, format=None):

    #user = request.user
    event = Event.objects.get(pk=pk)
    news = event.get_news_items().all()
    paginator = LimitOffsetPagination()
    result_page = paginator.paginate_queryset(news, request)
    serializer = NewsItemSerializer(result_page, many=True, context={'request':request})
    response = Response(serializer.data, status=status.HTTP_200_OK)
    return response

Answer 1

另一种选择是从分页类继承，对视图类的更改较少：

 from rest_framework.pagination import LimitOffsetPagination

class EventNewsItems(APIView, LimitOffsetPagination):

    def get(self, request, pk, format=None):
        event = Event.objects.get(pk=pk)
        news = event.get_news_items().all()

        results = self.paginate_queryset(news, request, view=self)
        serializer = NewsItemSerializer(results, many=True)
        return self.get_paginated_response(serializer.data)
