OmniAuth操作控制器錯誤

Question

我正在使用OmniAuth gem與我的Rails應用程序來允許用戶將他們的Facebook帳戶添加到應用程序，並且我遵循Ryan Bates的教程，但是我繼續得到這個Rails錯誤。

未定義＃

局部變量或方法`authentications_url」這是對認證控制器：

class AuthenticationsController < ApplicationController 

    def index 
     @authentications = current_user.authentications if current_user 
    end 

    def create 
     auth = request.env["omniauth.auth"] 
     current_user.authentications.find_or_create_by_provider_and_uid(auth['provider'],auth['uid']) 
    flash[:notice] = "Authentication successful." 
     redirect_to authentications_url 
    end 

    def destroy 
     @authentication = current_user.authentications.find(params[:id]) 
     @authentication.destroy 
     flash[:notice] = "Successfully destroyed authentication." 
     redirect_to authentications_url 
    end

你的錯誤是在告訴你，你的路由不存在。運行rake routes在命令提示符下，看看你是否有一個authentications路線

從ASCIIcasts版本的插曲，你config/routes.rb文件應類似於此：

ProjectManage::Application.routes.draw do |map| 
    match '/auth/:provider/callback' => 'authentications#create' 
    devise_for :users 
    resources :projects 
    resources :tasks 
    resources :authentications # <-- This is the one you're missing 
    root :to => 'projects#index' 
end
