Django 删除和修改用户的评论

我已经添加到我的博客帖子评论现在的问题是，我正试图创建删除功能，我有一个，但现在伊芙乌塞特萨克登录可以删除所有的评论，我如何解决这个问题，用户只能删除自己的评论？？ 最有趣的是，我在我的帖子上有这个函数，它会运行，如果我试图对我的评论做同样的操作，那么我会得到404错误。我试过几种不同的方法，但都不管用你是我唯一的希望：）

{{comment.author}{{comment.created|u于|日期：“df，yg:i”}

这里还没有评论：(

{%endfor%}
{%endblock内容%}

首先在注释模型中设置作者外键（用户）。然后在视图中检查此条件：

if comment.author == request.user:
  comment.delete()
