Exception Notification Gem and Rails 3

Question

I\'m trying to get this up and running, but I see \"uninitialized constant ExceptionNotifier\" whenever I start my server.

Answer 1

I am using rails 3.0.4 and had the same issue as above. The only solution that worked for me was to install the v1.2 of the exception_notification for rails 3 (make sure you use the correct branch/version) as a PLUGIN

rails plugin install https://github.com/railsware/exception_notification.git

and use in production.rb the code everyone mentions:

config.middleware.use ExceptionNotifier,
  :email_prefix => "[some prefix] ",
  :sender_address => %{"Notifier" <notify@domain.com>},
  :exception_recipients => %w{recipient@domain.com}

It definitely did not work for me as a gem and the readme does say " Exception Notifier Plugin for Rails " and mentions nothing about installing it as gem.

Answer 2

It seems that Rails 3 can't use this plugin in gem form. Maybe rack apps can't be loaded from gems? I installed it as a plugin instead and changed the config syntax to:

config.middleware.use "::ExceptionNotifier"

instead of

config.middleware.use ExceptionNotifier

Answer 3

Keep it simple silly

In gemfile

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

In application.rb file

  config.middleware.use ExceptionNotifier,
 :email_prefix => "[ERROR] ",
 :sender_address => %{"Exception Notifier" <Dummy_email@exapmle.com>},
 :exception_recipients => %w{Dummy_email@example.com}

Your are Done.. :*

Answer 4

I was able to get it to work with the following in production.rb:

config.after_initialize do
 config.middleware.use ExceptionNotifier,
      :email_prefix => "[Whatever] ",
      :sender_address => %{"notifier" <notifier@example.com>},
      :exception_recipients => %w{exceptions@example.com}
end

Answer 5

till now ( 2012-Aug-03) the official site is : https://github.com/smartinez87/exception_notification, and according the README, it support Rails3 perfectly.

step1. edit your Gemfile:

gem 'exception_notification'

step2.

As of Rails 3 ExceptionNotification is used as a rack middleware, so you can configure its options on your config.ru file, or in the environment you want it to run. In most cases you would want ExceptionNotification to run on production. You can make it work by

Whatever::Application.config.middleware.use ExceptionNotifier,
  :email_prefix => "[Whatever] ",
  :sender_address => %{"notifier" <notifier@example.com>},
  :exception_recipients => %w{exceptions@example.com}
