在Django-rest-framework中过滤ListAPIView [英] Filtering ListAPIView in django-rest-framework

问题描述

我正在使用ListAPIView，但无法过滤结果。我的代码是：

I'm using ListAPIView, but I can't filter the results. My code is:

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，但是文档说该类也受支持。如果我尝试通过通用视图实现自定义 get ，则不知道如何重新实现 paginate_by 。有任何想法吗？

In this case, lookup_field is ignored, but the documentation says that it's supported for this class too. If I try to implement a custom get over a generic view, I don't know how to reimplement paginate_by. Any ideas?

推荐答案

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')
