Examples

  class User < ActiveRecord::Base
    has_one :profile, :autocreate => true
  end

  class Profile < ActiveRecord::Base
    belongs_to :user
  end

  # make a single user
  >> user = User.create(:name => 'Dr. User')
  => #<User id: 1, name: "Dr. User">

  # look for any profile objects
  >> Profile.count

  # access the user's profile object to see it automatically created
