rails开发利器：时刻监控我们的程序错误rails exception_notification

1. 介绍
   exception_notification
   rails 2.3.8 https://github.com/smartinez87/exception_notification/tree/2-3-stable
   rails 3 https://github.com/rails/exception_notification
   
   
2.  install plugin
   ruby script/plugin install git://github.com/rails/exception_notification.git -r '2-3-stable'
3.  configuration
   将如下代码加入到environment.rb的最后
   

   ExceptionNotification::Notifier.exception_recipients = %w([email protected]) #接受错误的邮件
   ExceptionNotification::Notifier.sender_address = %("Application Error" ) #发送错误的邮件
   |ExceptionNotification::Notifier.email_prefix = "[APP]" #定义发送错误的级别，默认是ERROR
   

   2.3 update application_controller.rb
   

    include ExceptionNotification::Notifiable

4. 如何想能development环境下测试，需要增加如下代码至application_controller.rb

     def local_request?
      false
     end
   

   并修改config/environments/development.rb

   config.action_controller.consider_all_requests_local = false
   config.action_mailer.raise_delivery_errors = true
   

   
   
5. rails2如何配置发送邮件？
   
   
6. 资料
   https://github.com/rails/exception_notification/tree/2-3-stable
   
   
7. rails3中的配置
   新增gem
   

   gem 'exception_notification', :require => 'exception_notifier'

   
   
   
   config/application.rb文件
   

       config.middleware.use ExceptionNotifier,
         :email_prefix => "[APP] ",
         :sender_address => %{"异常通知" },
         :exception_recipients => %w{[email protected]}
