Rails，Omniauth，Authlogic和Facebook - 第一步

Question

我試圖讓我的應用程序使用Rails，Authlogic和Omniauth來登錄Facebook登錄。儘可能精確地遵循http://railscasts.com/episodes/235-omniauth-part-1的第一步。

我：

• 加入omniauth寶石，運行bundle install。
• 創建了一個新的身份驗證腳手架，其字段爲user_id,provider和uid。
• 添加的路線：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 
  

然後，服務器無法重新啓動：

Answer 1

的omniauth創業板剛剛碰到1.0版，截至昨天（http://intridea.com/2011/11/2/omniauth-1-0），並且對如何使用寶石有一些改變沒有包含在railscast中。

我發現我的這個頁面上的解決方案：https://github.com/intridea/omniauth/wiki/OmniAuth-1.0

最大的不同的是，每一種策略現在包含它自己的寶石之內，所以對於Facebook，你會改變你的寶石文件中的行，目前寫着「創業板'omniauth'「改爲」gem'omniauth-facebook'「。

我不必更改任何其他代碼，而且您可能必須運行「軟件包更新」才能讓所有內容都點擊。

Answer 2

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

Answer 3

我只是碰到了這個問題，這是什麼毛病我：

你不能在發展列表您Facebook的OAuth寶石在你的寶石文件。 Heroku只讀取生產版本，因此將其移出開發列表。
