Django Rest Framework分页和过滤

问题描述

嗨，我正在尝试使用分页进行过滤，但是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)

这是我的分页课程。

class StandardPagesPagination(PageNumberPagination):
      page_size = 10

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

您能帮我解决这个问题吗？我找不到任何解决方案。

解决方法

如果您重写get方法，则必须确保知道原始实现的样子。

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

因此filter_queryset是这里丢失的部分。
