Ruby on Rails中的Omniauth路由錯誤

Question

我跟着Rails Casts Episode #360關於如何集成Facebook登錄。

當我點擊「登錄與Facebook」，我得到這個錯誤：

Routing Error 

No route matches [GET] "/auth/facebook" 

這裏是我的路線文件：

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' 

其他所有的文件我已經在改變RailsCast與教程中的完全相同。

我的AppId和Secret正在工作，但現在我得到路由錯誤。

有什麼建議嗎？

感謝

這是耙路線的結果：

不會自動生成，路徑/ auth /中的Facebook，如果在那裏它實際上不會做任何事情，除非你將其映射到一些控制器功能。但是你不應該這樣做。

確保您確實向Facebook發送了請求，否則omniauth將無法執行任何操作。

http://developers.facebook.com/docs/howtos/login/getting-started/

你應該要麼重定向到/ auth /中的Facebook /回調對失敗是成功或/ auth /中故障處理Facebook的您的要求的迴應。
