Rails/heroku：如何使我的應用程序在heroku上工作

Question

我有一個rails（2.3.5）應用程序，我不得不對它做一些更改，包括更改db。因此，本地工作正常，但是當我嘗試將其推送到heroku時，當我嘗試訪問應用程序時，我的瀏覽器上出現「應用程序錯誤」。我推送了新的代碼，引導並使用我的本地項目填充了heroku數據庫。

這就是我與「heroku日誌」，有什麼想法？ ：

Answer 1

它看起來像有一個在你的控制器中的一個語法錯誤：

sms_controller.rb:232: syntax error, unexpected $end, expecting kEND (SyntaxError) 

Answer 2

在您的SMS控制器看一看，確保每個def [1]與end封閉

日誌文件不一定非常令人生畏。請注意，關鍵信息是在應用程序創建並啓動後陳述的，因爲這是問題出現的地方，最重要的信息更接近頂端。之後的第一行指出語法錯誤。所有後續行都是錯誤，一旦頂部錯誤被修復，這些錯誤將會消失。

[1]不一定是def - 可能是一個塊，一個循環，迭代等
