的users_contoller＃28是PAGINATE后跟一个很长的SQL查询：

@discussions = Discussion.find_by_sql("SELECT d.*, MAX(c.created_at) AS lastCommentTime 
       FROM discussions d JOIN comments c ON d.id = c.commentable_id 
       WHERE c.commentable_type = 'Discussion' AND c.user_id = #{@user.id} 
       GROUP BY d.id ORDER BY lastCommentTime DESC") 
       .paginate(:page => params[:page], :per_page => 10)

所以我已经删除断行在点之前，它是固定的。感谢你们的超级大国！对于新手来说，很难发现该日志文件中的关键错误行。 :)

你可以更新你的问题来包含你的'users_controller.rb'吗？ – theTRON 2011-04-18 06:01:58

很高兴你发现你的问题！学习有效地读取堆栈跟踪可能是我开发的最重要的技能（这可能会说我的编程不太好）。 :) – 2011-04-18 15:21:03

应该有一本关于rails调试模式的书。 :)也许那里已经有了 – randomor 2011-04-19 04:12:36

堆栈跟踪在第28行提到app/controllers/users_controller.rb。在此文件及其附近有什么代码？这可能是你会发现你的问题的地方。

此外，我知道这听起来很愚蠢，但三重检查一切都检查到您的Git回购。由于Heroku是基于Git的，因此很容易忘记检查某些内容，并将git push旧版本的应用程序添加到服务器。
