未初始化的常量的ApplicationController（NameError） - 应用程序工作正常，本地

我已经建立了一个简单的在线申请一个Rackspace的云服务器上，但我发现从PHUSION客运以下错误信息：未初始化的常量的ApplicationController（NameError） - 应用程序工作正常，本地

我m不知道这里发生了什么 - 应用程序在我的本地主机上工作得很好 - 所有的gem都已安装，迁移被清除 - 那么究竟是什么问题呢？

你可以发布你的config/environment.rb和config/production.rb吗？ –

这里是链接到站点，你可以看到phusion乘客转储http://173.203.64.44/ – Ali

你可以尝试运行'rails server -e production'来查看应用程序是否工作？ –

我想你是缺少ApplicationController。所有其他控制器从这个类

简单application_controller.rb

class ApplicationController < ActionController::Base 

end

包含此文件 - 这是我不明白。它在我的本地主机上正常工作，但它给了我这个错误在线:( – Ali

对不起 - 你是对的，该文件包括但由于某种原因filezilla选择不上传这个文件。 – Ali

在我来说，继承我在routes文件拼写错误的“应用程序”。一定要检查你的拼写！
