Ruby decorators

Good overview of decorator options for ruby listed in thoughtbot article

The simplest implementation is:

class Decorator < SimpleDelegator
  def self.wrap(collection)
    collection.map do |obj|
      new obj
    end
  end

  # to mimic draper
  # Be aware that draper does some magic to implement it,
  # so this will not work exactly the same as draper
  # https://github.com/drapergem/draper/blob/master/lib/draper/view_context.rb
  def h
    ActionController::Base.helpers
  end
end

class WorkerDecorator < Decorator
end
