The Exception Notifier plugin provides a mailer object and a default set of templates for sending email notifications when errors occur in a Rails application. The plugin is configurable, allowing programmers to specify:
The email includes information about the current request, session, and environment, and also gives a backtrace of the exception.
For information about configuration and usage in your project, see the README.
