Django DefaultRouter 和 ViewSets 问题

Question

我有这条路线：

router.register(r'posts/(?P<post_id>\d+)/comments', views.CommentViewSet)

如何在 CommentViewSet class 中获取 post_id？
更新：
views.py

class CommentViewSet(viewsets.ModelViewSet):
    queryset = Comment.objects.all()
    serializer_class = CommentSerializer
    permission_classes = (MyPremmission,)
    

    def get_queryset(self):
        queryset = self.queryset.filter(post__id = post_id)
        return queryset


    def perform_update(self, serializer):
        serializer.save(author=self.request.user)

Answer 1

试试这个

def get_queryset(self):
    post_id = self.kwargs.get('post_id')
    queryset = self.queryset.filter(post__id = post_id)
    return queryset
