我关注了Rails Casts Episode #360，了解如何集成 facebook 登录。
当我单击“使用 Facebook 登录”时，出现以下错误：
Routing Error
No route matches [GET] "/auth/facebook"
这是我的路线文件：
Frostfiress::Application.routes.draw do
ActiveAdmin.routes(self)
devise_for :admin_users, ActiveAdmin::Devise.config
get "profiles/show"
#get 'questions/:tag', to: 'questions#index', as: :tag
#get 'places/:tag', to: 'places#index', as: :tag
match 'auth/:provider/callback', to: 'sessions#create'
match 'auth/failure', to: redirect('/')
match 'signout', to: 'sessions#destroy', as: 'signout'
resources :places
devise_for :users
devise_scope :user do
get 'register', to: 'devise/registrations#new', as: :register
get 'login', to: 'devise/sessions#new', as: :login
get 'logout', to: 'devise/sessions#destroy', as: :logout
get 'password/change', to: 'devise/passwords#edit', as: :password
end
resources :answers
resources :questions
root :to => "questions#index"
get '/:username', to: 'profiles#show'
我必须在 RailsCast 中更改的所有其他文件都与教程中的完全相同。
我的 AppId 和 Secret 正在工作，但现在我收到路由错误。
有什么建议么？
谢谢
