Defining Class methods in a Module

By kenglish

The code should speak for itself. Make sense?

module Loveable
  module ClassMethods
    def give_hug
    end
  end
  def self.included(base)
    base.extend(ClassMethods)
  end
end
 
class Person
  include Loveable
 
  give_hug
 
end

I fuzzy as to why a certain Rails genius would suggest it is better to do it this way
(see line 7):

module Loveable
  module ClassMethods
    def give_hug
    end
  end
  def self.included(base)
    base.send :extend, ClassMethods
  end
end
 
class Person
  include Loveable
 
  give_hug
 
end
