= Rails Engine Decorators

Extend Rails Engine's business logic (models, controllers, helpers, etc.) easily from

your application or other engine.

This solution was first implemented in the Forem engine, see https://github.com/radar/forem/pull/260

== Usage

(From Forem's patch):

Standard practice for including such changes in your application or extension is to create a file within the relevant app/models or app/controllers directory with the original class name with _decorator appended.

### Adding a custom method to the Post model:

    # app/decorators/models/forem/post_decorator.rb

    Forem::Post.class_eval do

      def some_method

        ...

      end

    end

### Adding a custom method to the PostsController:

    # app/decorators/controllers/forem/posts_controller_decorator.rb

    Forem::PostsController.class_eval do

      def some_action

        ...

      end

    end

The exact same format can be used to redefine an existing method.
