Basically i had :

class Base
  def self.match_attributes(hash, attributes = self::ATTRIBUTES_MAPPING)
    #do work on attributes
  end
end

class SpecificMapper < Base
  ATTRIBUTES_MAPPING = { ... }
end

Then i could do :
Base.match_attributes(hash, { ... })
or
SpecificMapper.match_attributes(hash)


Then i read http://matt.aimonetti.net/posts/2012/07/30/ruby-class-module-mixins/ and i wanted to refactor that because i'm not using any instance methods.


module Foo
  def self.hello
    puts "Yo"
  end
end


module Bar
  include Foo
end

Foo.hello #=> Yo
Bar.hello #=> NotMethodError
