rails app奇怪的错误,没有跟踪,没有日志输出帮助请认真发出"!!处理请求时出现意外错误:

Question

所有突然之间,甚至在更换我的应用程序后,我得到一个错误,如:

!! Unexpected error while processing request: undefined method `show' for "/":String

我已经用几个小时之前的备份替换了我的代码,当我通过打开浏览器并单击真实页面来构建新功能时,我不断测试我的应用程序,来自备份的旧代码完美无缺但现在我无法将我的应用程序运行到工作了

救命!在轨道编码器上任何更高级的红宝石可以帮我解决这个问题吗？谢谢

rails/server的完整输出不是日志!

解决方案和吸取的教训

我有一个自定义初始化程序,用于记录而不是资产,这个搞砸了它在升级到rails版本的最新ruby时破坏了.如果您遇到这种奇怪的行为,请务必在应用代码之前检查/ config /和初始值设定项; p
