Decorator using simple delegator that follows most of draper syntax

application_decorator.rb

require 'delegate'

class ApplicationDecorator < SimpleDelegator
  def self.decorate(instance)
    return nil if instance.blank?
    new instance
  end

  def self.decorate_collection(collection)
    return [] if collection.nil? || collection.length.zero?
    collection.map { |instance| new instance }
  end

  private

  def h
    ApplicationController.helpers
  end

  def r
    Rails.application.routes.url_helpers
  end

  def object
    __getobj__
  end

  def company
    Company.first
  end
end

I only used the basics of draper. The only change is this:

def person
  PersonDecorator.decorate(object.person)
end

instead of this

  decorates_association :person, with: PersonDecorator
