我有一个rails（2.3.5）应用程序，我不得不对它进行一些更改，涉及更改数据库。所以，本地它工作正常，但是当我试图将它推送到heroku时，当我尝试访问应用程序时，我的浏览器上出现“应用程序错误”。我推送了新代码，引导并用我的本地项目填充了heroku数据库。
这是我用“heroku日志”得到的，任何想法？ ：

答案 0 :(得分：2)
看起来你的一个控制器中存在语法错误：
sms_controller.rb:232: syntax error, unexpected $end, expecting kEND (SyntaxError)
答案 1 :(得分：1)
查看您的短信控制器并确保每个def [1]已关闭，并end
日志文件不一定是令人生畏的。请注意，关键信息是在应用程序创建然后启动后声明的，因为这是问题开始的地方，最重要的信息更接近顶部。之后的第一行说明了语法错误。所有后续行都是错误，一旦修复了最高错误，这些错误就会消失。
[1]不一定是def - 可以是块，循环，迭代等。
