升級到Rails 3.2後，我的rake任務被破壞

Question

升級到Rails 3.2後，我的rake任務無法自動加載模型。

以下是以工作軌道3.1：

我的應用程序的代碼是開源了，所以你可以點擊此處查看：

我做了唯一的修改是增加a

「Rails.application.eager_load！」行到上面顯示的rake任務的開始。沒有它，它不會加載「皮膚」庫。

UPDATE 我試圖通過添加調試這使上面顯示的堆棧跟蹤的每一行語句，我可以看到這樣的事情：

eager_load_path: /srv/www/gamersmafia/current/app/mailers 
file found: /srv/www/gamersmafia/current/app/mailers/notification.rb 
require_dependency notification 
... notification 
rake aborted! 

這大致似乎表明Rails是找到通知。 rb文件，但當它試圖加載它不能。

Answer 1

gem install notification 

也許只是做的伎倆，看到No such file to load -- notification表示一個require 'notification'失敗。
