ActiveAdmin錯誤 - 未定義的方法`action_methods'爲 「管理/ admin_users」：字符串

Question

在導航爲admin_users的ActiveAdmin資源得到以下錯誤：跟蹤

undefined method `action_methods' for "admin/admin_users":String 

前幾行：

activeadmin (0.3.2) lib/active_admin/resource/action_items.rb:51:in `block in add_default_action_items' 
activeadmin (0.3.2) lib/active_admin/views/action_items.rb:9:in `instance_eval' 
activeadmin (0.3.2) lib/active_admin/views/action_items.rb:9:in `block (2 levels) in build' 
activeadmin (0.3.2) lib/active_admin/arbre/builder.rb:68:in `block in build_tag' 
activeadmin (0.3.2) lib/active_admin/arbre/builder.rb:96:in `with_current_dom_context' 
activeadmin (0.3.2) lib/active_admin/arbre/builder.rb:67:in `build_tag' 
activeadmin (0.3.2) lib/active_admin/arbre/builder.rb:77:in `insert_tag' 
activeadmin (0.3.2) lib/active_admin/arbre/html/element.rb:17:in `span' 

我基本上只是按照下面列出的步驟：http://railscasts.com/episodes/284-active-admin?view=asciicast

發現問題。在application_controller.rb中有一個名爲@controller的實例變量。獲得的經驗...從不使用變量的保留關鍵字。
