我的導軌應用程序在heroku中不起作用

我是新的導軌。我有一個應用程序在我的本地熱點工作完美，我上傳到Heroku，但是當我到達網站時，我收到了此消息。

您正在查找的頁面不存在。

這裏是我的日誌，我做了數據庫遷移

我無法弄清楚什麼是錯的，有人能幫助我嗎？

Answer 1

您的瀏覽器錯誤消息和您的日誌都表明相同的事情。

2014-03-29T03:27:00.883455+00:00 app[web.1]: ActionController::RoutingError (No route matches [GET] "/"): 

這意味着當您未設置路線「/」時，您正嘗試去「/」。你必須通過在config/routes.rb中指定以下行來設置它。

root :to => 'home#index' 

'home＃index'是一個任意值。您可以將其設置爲您希望主頁使用的任何控制器方法。 'home'是指控制器，而'index'是指方法名稱。
