我的评论回复功能不起作用？

Question

我正在创建博客，但是我停留在评论回复功能上。我不知道如何创建一个“回复”功能，用户可以从中回复评论。我做了很多尝试，但是它仍然像其他评论一样显示这些评论，而不是对特定评论的答复。

这是模型。py

class Comment(models.Model):
    post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name = "comments")
    name = models.CharField(max_length = 200)
    body = models.TextField(default = True)
    pub_date = models.DateTimeField(auto_now_add = True)
    reply = models.ForeignKey('Comment',null = True,blank = True,on_delete=models.CASCADE)


    class Meta:
        ordering = ['-pub_date']



    def __str__(self):
       return self.name


    @property
    def get_replies(self):
        return self.replies.all() 



class Reply(models.Model):
    post = models.ForeignKey(Comment,on_delete=models.CASCADE,related_name = "replies")
    name = models.CharField(max_length = 200)
    body = models.TextField(default = True)

这是views.py

def BlogDetail(request,pk):

    post = get_object_or_404(Post,pk = pk) 
    comment = CommentForm(request.POST or None)
    subscribe = Subscribe() 
    reply = ReplyForm(request.POST or None)



    if request.method  == 'POST':
        subscribe = Subscribe(request.POST) 
        comment = CommentForm(request.POST)
        reply =  ReplyForm(request.POST)

        if comment.is_valid():
            comment.instance.post = post
            comment.save()  


        elif subscribe.is_valid():
            subscribe = subscribe.save(commit = True)
            return redirect('index')

        elif reply.is_valid():
            reply.instance.com = com
            reply = reply.save(commit = True)
            return redirect('index')

    return render(request,'app/blog.html',{'blog_object':post,'comment':comment,
        'subscribe':subscribe,'reply':reply,
        })

这是blog.html
