Django Rest Framework 分页和过滤

Question

大家好，我正在尝试使用分页进行过滤，但我无法获得想要的结果。

这是我在 views.py 中的功能。

class OyunlarList(generics.ListAPIView):
    # queryset = Oyunlar.objects.all()
    pagination_class = StandardPagesPagination
    filter_backends = [DjangoFilterBackend]
    filterset_fields = ['categories__name', 'platform']
    # serializer_class = OyunlarSerializer
    def get_queryset(self):
        queryset=Oyunlar.objects.all()
        oyunlar=OyunlarSerializer.setup_eager_loading(queryset)

        return oyunlar
    def get(self,request,*args,**kwargs):
        queryset = self.get_queryset()
        serializer=OyunlarSerializer(queryset,many=True)
        page=self.paginate_queryset(serializer.data)
        return self.get_paginated_response(page)

这是我的分页class。

class StandardPagesPagination(PageNumberPagination):
      page_size = 10

这是我得到的 json 但是当我写 localhost/api/games?platform=pc 或 localhost/api/games?categories=Action 时它不起作用。

{
    "count": 18105,
    "next": "http://127.0.0.1:8000/api/oyunlar?categories__name=&page=2&platform=pc",
    "previous": null,

你们能帮我解决这个问题吗？我找不到任何解决方案。

Answer 1

如果您覆盖 get 方法，您必须确保您知道原始实现的样子。


    def get(self,request,*args,**kwargs):
        queryset = self.filter_queryset(self.get_queryset())
        ...

所以 filter_queryset 是这里缺少的部分。
