Rails，Omniauth，Authlogic和Facebook - 第一步

Question

我试图让我的应用程序使用Rails，Authlogic和Omniauth来登录Facebook登录。尽可能精确地遵循http://railscasts.com/episodes/235-omniauth-part-1的第一步。

我：

• 加入omniauth宝石，运行bundle install。
• 创建了一个新的身份验证脚手架，其字段为user_id,provider和uid。
• 添加的路线：match '/auth/:provider/callback' => 'authentications#create'

• 添加到配置/初始化/ 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

的omniauth创业板刚刚碰到1.0版，截至昨天（http://intridea.com/2011/11/2/omniauth-1-0），并且对如何使用宝石有一些改变没有包含在railscast中。

我发现我的这个页面上的解决方案：https://github.com/intridea/omniauth/wiki/OmniAuth-1.0

最大的不同的是，每一种策略现在包含它自己的宝石之内，所以对于Facebook，你会改变你的宝石文件中的行，目前写着“创业板'omniauth'“改为”gem'omniauth-facebook'“。

我不必更改任何其他代码，而且您可能必须运行“软件包更新”才能让所有内容都点击。

Answer 2

我不得不在我的config/development.rb文件中做'require'omniauth“'或'require”omniauth-facebook“'。

Answer 3

我只是碰到了这个问题，这是什么毛病我：

你不能在发展列表您Facebook的OAuth宝石在你的宝石文件。 Heroku只读取生产版本，因此将其移出开发列表。
