在django-rest-framework中过滤ListAPIView

Question

我正在使用ListAPIView,但我无法过滤结果.我的代码是:

class UserPostReadView(generics.ListAPIView):
    serializer_class = PostSerializer
    model = serializer_class.Meta.model
    queryset = model.objects.order_by('-post_time')
    lookup_field = 'poster_id'
    paginate_by = 100

在这种情况下,lookup_field被忽略,但文档说它也支持这个类.如果我尝试get在通用视图上实现自定义,我不知道如何重新实现paginate_by.有任何想法吗？

我找到了解决方案

class UserPostsReadView(generics.ListAPIView):
    serializer_class = PostSerializer
    model = serializer_class.Meta.model
    paginate_by = 100
    def get_queryset(self):
        poster_id = self.kwargs['poster_id']
        queryset = self.model.objects.filter(poster_id=poster_id)
        return queryset.order_by('-post_time')
