今天看看一个Exception Notificatio插件:

ruby script/plugin install exception_notification

然后我们在ApplicationController里添加如下代码:

include ExceptionNotifiable

并且在config/environment.rb里配置Email:

ExceptionNotifier.exception_recipients = %w(you@yourdomain.com)
ExceptionNotifier.sender_address = %("Application Error" <notifier@yourdomain.com>)
ExceptionNotifier.email_prefix = "[Your Application Name]"

这样当页面出错时就会以Email形式发送给recipients
