Rails extending ActiveRecord::Base

Question

I\'ve done some reading about how to extend ActiveRecord:Base class so my models would have some special methods. What is the easy way to extend it (step by step tutorial)?<

Answer 1

Step 1

module FooExtension
  def foo
    puts "bar :)"
  end
end
ActiveRecord::Base.send :include, FooExtension

Step 2

# Require the above file in an initializer (in config/initializers)
require 'lib/foo_extension.rb'

Step 3

There is no step 3 :)
