大佬教程收集整理的这篇文章主要介绍了显示回复按钮对评论不起作用，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
显示回复按钮应该针对不同的评论。当我按下显示回复按钮时，它会打开不属于该评论的不同回复。

我认为这是一个逻辑错误。有人可以帮我找出这个错误吗？虽然一切正常，但我的回复按钮无法正常工作。
models.py 的变化。更新 parent 中的 BlogComment（添加 related_name）
parent=models.ForeignKey('self',on_delete=models.CASCADE,null=True,related_name='replies' )
在 views.py 处发生变化comments
comments= BlogComment.objects.filter(post=post,parent=None).prefetch_related('replies')
您不需要单独查询回复。
在html中（仅用于回复。请根据您的要求进行更改）
{% for comment in comments %}
{% for reply in comment.replies.all %}
{{ reply.comment }}
{% endfor %}
{% endfor %}
这会起作用。记住related_name=replies
（抱歉回答不清楚。办公室下班了，我要走了。祝你好运）
