M.Hartl在第10/11章（激活/密碼重置）上的Ruby on Rail錯誤

Question

我是RoR的新手，並且遵循Michael Hartl的Ruby on Rails示例應用教程。 Whist完成第10章和第11章已經遇到並且問題我不確定如何解決。

我所有的測試都通過，但當通過Heroku.com直播使用應用程序時，應用程序將發送自動激活和密碼重置電子郵件，但是當用戶點擊這些電子郵件中的鏈接時，無標題：空白'頁面。

有誰知道我該如何解決這個問題。請參閱下面的一些相關代碼，並讓我知道你是否需要再看。

任何幫助將不勝感激。

非常感謝（事先）

Answer 1

變化line:62在config/environments/production.rb

config.action_mailer.default_url_options = { host: 'safe-falls-22225.herokuapp.com' } 

你有一個錯字在你default_url_options
