Interior Decorator

Ultra-lightweight decorator for Rails models. Only 42 actionable lines of code!

Installation

Include it in your Gemfile.

gem 'interior_decorator'

Usage

Create Your Decorator

Add your decorator in app/decorators:

class UserDecorator < InteriorDecorator

  def full_name
    "#{first_name} #{last_name}"
  end

  def updated_at
    model.updated_at.strftime("%A, %B %e, %Y")
  end

end

Method calls are sent to the model via method_missing, so you can call model methods directly as in the full_name method defined above.

If there's going to be a method name collision then call model methods with model..

You can access helper methods with helper., or h. for short.

Decorate Your Objects

In Controllers

Just call decorate:

UserDecorator.decorate(user)

In Views

Just call decorate:

<%= decorate(user) %>

Or d for short.

On Collections

Just call decorate. You'll get an array of decorated objects.

UserDecorator.decorate(users)

<%= decorate(users) %>
