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 had the same problem just now and resolved it this way:

Gemfile

source 'http://rubygems.org'
gem 'exception_notification_rails3', :require => 'exception_notifier'

application.rb

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

I'm refactoring a Rails 2.3 project to 3.0, so I haven't tried this on a fresh install.

Edit:

It might actually be better (or "more correct") to put the ExceptionNotifier initialization in a separate initializer file in config/initializers/ instead of application.rb.

config/initializers/exception_notifier.rb

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