Module: RescueWithHelper

Defined in:
lib/action_controller/rescue_with_helper.rb

Overview

When an exception happens inside a view, it is wrapped with an ActionView::TemplateError. The lookup for the rescue_with_handler then fails to find the handle for the original exception. This solution special cases the template error to look also at the wrapped exception and if there is a handler for that exception, then call it and ignore the wrapping.
