Rails,Omniauth,Authlogic和Facebook--迈出了第一步

Question

我正在尝试使用Rails,Authlogic和Omniauth让Facebook登录我的应用程序.我正在尽可能精确地遵循http://railscasts.com/episodes/235-omniauth-part-1的第一步.

我有:

• 添加omniauth宝石,运行bundle install.
• 创建一个新的认证漂亮的支架与领域user_id,provider和uid.
• 添加了路线: match '/auth/:provider/callback' => 'authentications#create'

• 添加到config/initializers/omniauth.rb:

  Rails.application.config.middleware.use OmniAuth::Builder do
    provider :facebook, '20...my_app_id', 'bc...my_app_secret'
  end
  

然后服务器无法重新启动:

Answer 1

我必须在我的config/development.rb文件中执行'require"omniauth"'或'require"omniauth-facebook"'.
