Defined in:
lib/haveapi/extensions/exception_mailer.rb

Overview

This extension mails exceptions raised during action execution and description construction to specified e-mail address.

The template is based on Sinatra::ShowExceptions::TEMPLATE, but the JavaScript functions are removed, since e-mail doesn’t support it. HaveAPI-specific content is added. Some helper methods are taken either from Sinatra or Rack.
