Heroku的Rails應用程序顯示「應用程序錯誤」

當我試圖訪問一個最近發佈在Heroku上的Rails應用程序，它給了我下面的錯誤：Heroku的Rails應用程序顯示「應用程序錯誤」

Application Error 
An error occurred in the application and your page could not be served. Please try again in a few moments. 

If you are the application owner, check your logs for details.

當我檢查「Heroku的日誌」我看到以下內容：

2013-02-15T18:56:06+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=olivetalk.org fwd=76.168.74.9 dyno= queue= wait= connect= service= status=503 bytes=

我找不出什麼可能是錯的。有什麼建議？

UPDATE：下面是從loggly插件錯誤：

H10只是意味着你的應用崩潰了，日誌中應該有其他指標。 – catsby 2013-02-15 19:18:47

您是否已將loggly或logentries插件添加到您的應用程序中？他們會給你提供比heroku日誌命令更多的信息。 – Sean 2013-02-15 19:28:58

感謝您的提示。我安裝了loggly並在上面發佈了loggly日誌。我仍然不明白什麼是錯誤的。任何想法？ – 2013-02-15 19:53:42

您所添加的 'PG' 寶石到您的Gemfile（或正確地配置您的database.yml）？如果數據庫設置不正確，Heroku應用程序將崩潰。

我創建了數據庫並輸入了所有憑證。無論如何只是檢查數據庫連接？非常感謝 – 2013-02-15 20:42:50
