Module: DelegatePresenter::ApplicationController

Defined in:
lib/delegate_presenter/application_controller.rb

Overview

This module adds a method so DelegatePresenter::Base can access your Rails helpers You’ll need to extend your ApplicationController with this module name

Earlier versions of the gem extended ApplicationController for you, but introduced bugs (possibly dealing with load order???) WD-rpw 10-20-2011
