adamhunter / wrap.rb
Last active January 2, 2016 01:19
wrapping an ActiveRecord instance in a subclass with more functionality. Given an instance you didn't create (aka current_user, User class), you can get a new instance who's class is the wrapping class. The primary reason to do this is for smaller objects in different parts of your system.
# per sean cribb's suggestion some time ago
User.new.becomes(Super::User) # thanks Rails :)
# below not needed, for reference
User = Class.new(ActiveRecord::Base)
class Super::User < ::User
def self.wrap(user)
