新的Rails Heroku应用程序引发ApplicationError（Heroku错误H10）

[英]New Rails Heroku app throwing an ApplicationError (Heroku error H10)

问题描述

我刚刚在Heroku上部署了一个（以前工作的）Rails应用程序。 问题是，每当我转到URL时，它都会因应用程序错误而失败。 老实说，我不确定该怎么做。 大多数类似的错误都涉及sqlite3，但已从应用程序中删除。 除了这些，我不确定该怎么做，有什么建议吗？

您的Message模型中有一个错误。 

validates :content, :length => { maximum: => 200 }

需要是 

validates :content, :length => { :maximum => 200 }

解决方案2

根据错误消息中的这一行，看来您的消息模型中有语法错误。 Heroku最有可能尝试构建您的应用程序，当它遇到此错误时会崩溃。 

/app/models/message.rb:8: syntax error, unexpected tASSOC (SyntaxError)
←[36m2013-03-09T21:58:29+00:00 app[web.1]:←[0m   validates :content, :length =>
{ maximum: => 200 }
