Question

只需在我的rails应用程序中添加了新的评论功能，就偶然发现了此问题。我在Pics＃show中收到了NoMethodError，该错误来自我的_comment.html.haml部分。

我可以在显示页面上看到评论主题，但是发布评论后我得到了。可以返回未注释的照片，但不能转到我已评论的照片。

我已经盯着代码看了一段时间了，我需要一双新鲜的眼睛。

这是我的_comment部分。

%li
 = comment.body
%small
Submitted #{time_ago_in_words(comment.created_at)} ago
 = form_for [comment, Comment.new] do |f|
 = f.text_area :body, placeholder: "Add a Reply"
%br/
 = f.submit "Reply"
%ul
 = render partial: 'comments/comment', collection: comment.comments

一切都已修复，并且可以正常工作。必须传递@pic变量。谢谢

我的一个控制器中有一个NoMethodError
