我正在开发一个用 Ruby 自定义编写的小型 CMS，该网站使用 Mongrel 运行。不幸的是，我对 Ruby 一点也不熟悉。网站的一部分最近停止工作（与任何更新无关，所以我不确定是什么原因）

检查 rails 日志中的“production.log”显示以下内容：

ActionView::TemplateError (undefined method `name' for nil:NilClass) on line #25 of app/views/static/frontpage.rhtml: 22: <% Tabloid.find(:all, :limit => 4, :order = >'date DESC').each do |tabloid|%> 23: 24: <%= link_to tabloid.title, :controller => 'tabloid', :action => 'show', :id => tabloid.id % > 25:

<%= tabloid.date.strftime("%d of %B, %Y") %> By: <%= Profile.find(:first, :conditions => [ "user_id = ?", tabloid.user_id]) .name %> <%= Profile.find(:first, :conditions => [ "user_id = ?", tabloid.user_id]).surname %>

26:

<%= RedCloth.new(truncate(tabloid.texto, 250)).to_html %>

27: <% if tabloid.texto.size > 250 %> 28:

<%= link_to "阅读更多 >", :controller => 'tabloid', :action => 'show', :id => tabloid.id %>

等等。 Mongrel 日志实际上已经有一段时间没有更新了。关于问题是什么或我应该在哪里继续挖掘的任何指示？

Profile.find(:first, :conditions => [ "user_id = ?", tabloid.user_id])查询返回nil，因此他无法name对其执行
