Question

我在我的Rails应用程序中使用OmniAuth gem允许用户将他们的Facebook帐户添加到应用程序，我正在关注Ryan Bates的教程，但我继续得到这个Rails错误。

未定义的局部变量或方法`authentications_url'用于＃

以下是身份验证的控制器：

    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

您的错误告诉您您的路线不存在。在命令提示符处运行rake routes，看看您是否有authentications路由

在该剧集的ASCIIcasts版本中，您的config/routes.rb文件应与此类似：

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

OmniAuth动作控制器错误
