Cool. Well, I don't want to add manually something to "ActiveRecord::Base and include the module" The other solution "to introduce a subclass of \ActiveRecord:Base and implement the methods there." sounds better. But how to do this ? Any idea ?

This is probably the more Rubyish way. # in lib/foo.rb module Foo module Bar def my_new_method end end end ActiveRecord::Base.send :include, Foo::Bar Now my_new_method is a part of ActiveRecord::Base and you can use it from any of your models. This way you don't have to change any of your models and you're using Ruby's open classes, which makes you one of the cool kids :) If you really need to subclass, you can do that like: # in app/models/myarsubclass.rb class MyARSubclass < ActiveRecord::Base def my_new_method end end And then change all your models from: class SomeModel < ActiveRecord::Base end to: class SomeModel < MyARSubclass end But isn't that a lot more work? =dudley
