【问题描述】：
我正在使用 Devise + Omniauth (Facebook)，最近更新了我的 gems（Rails 3.0.5、Ruby 1.9.2）。在启动我的应用服务器时，routes.rb 中的以下行：
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks", :registrations => "registrations" }
已开始引发以下错误：

以这种方式命名的路由是否有新的 a 语法？
【问题讨论】：
-
我通过恢复到 rails 3.0.3 暂时解决了这个问题
-
我目前在 3.0.7 上遇到这个问题。只是给任何试图诊断的人的注释：当模型为 :omniauthable 时，即使没有传递给 do devise_for 的其他选项，我也会收到此错误：users
