ruby-on-rails - 500内部服务器错误

Question

我正在按照此处的教程进行操作:http://guides.rubyonrails.org/getting_started.html

一切正常，直到我尝试“8.1 渲染部分集合”我开始收到此错误消息:

500 Internal Server Error

If you are the administrator of this website, then please read this web application's log file and/or the web server's log file to find out what went wrong.

在我的开发日志文件中:

<p>
  <b>Name:</b>
  ');@output_buffer.append= ( @post.name );@output_buffer.safe_concat('

怎么了？

请帮忙。

编辑:views/posts/show.html.erb:

<p class="notice"><%= notice %></p>
 
<p>
  <b>Name:</b>
  <%= @post.name %>
</p>
 
<p>
  <b>Title:</b>
  <%= @post.title %>
</p>
 
<p>
  <b>Content:</b>
  <%= @post.content %>
</p>
 
<h2>Comments</h2>
<%= render :partial => "comments/comment",
           :collection => @post.comments %>
 
<h2>Add a comment:</h2>
<%= render "comments/form" %>
 
<br />
 
<%= link_to 'Edit Post', edit_post_path(@post) %> |
<%= link_to 'Back to Posts', posts_path %> |

编辑 2:

这里是views/comments/_comment.html.erb

<p>
  <b>Commenter:</b>
  <%= comment.commenter %>
</p>
 
<p>
  <b>Comment:</b>
  <%= comment.body %>
</p>

如果我删除以下应用运行:

<%= render :partial => "comments/comment",
           :collection => @post.comments %>

但是，如果我将 _comment.html.erb 的内容更改为 blablabla，它仍然显示相同的错误。

Answer 1

“语法错误，意外的 tASSOC，需要 ')'”

您似乎在某处缺少右括号。在不查看周围代码的情况下，这是我们能做的最好的事情。

编辑:“周围代码”是指围绕 views/posts/show.html.erb:20。
