Django Rest Framework,Filtering objects based on Forignkey relationship

I have a simple Blog app where anyone can add post and comment to post. Comments have forignkey relationship with Post. When I select url patch posts/<post id>/comments it shows all comments instead of the comments from related posts. All other CRUD functions works fine with the project.

The Git Link :https://github.com/Anoop-George/DjangoBlog.git

The problem occurs in view.py where comment object unable to filter comments which are related to specific posts.

class CommentListCreate(APIView):
    def get(self, request,pk):
        **comment = Comment.objects.filter()** # I need filter here
        serializer = CommentSerializers(comment, many=True)
        return Response(serializer.data)

First of all, don't use space in url argument or in general in urls. Url patch should be posts/<int:post_id>/comments.

Now, your class view looks like:

class CommentListCreate(APIView):
    def get(self, request, *args, **kwargs):
        id = kwargs.get("post_id", None)
        comment = Comment.objects.filter(post__id=id)
        serializer = CommentSerializers(comment, many=True)
        return Response(serializer.data)

I didn't get a chance to verify it but I am pretty sure it will work.
