You'll have to write your own accessor and mutator methods if you'd like to use value objects to represent some portion of your models. So, instead of: - -<ruby> -class Person < ActiveRecord::Base - composed_of :address, :mapping => [ %w(address_street street), %w(address_city city) ] -end -</ruby> - -you could write something like this: - -<ruby> -def address - @address ||= Address.new(address_street, address_city) -end - -def address=(address) - self[:address_street] = @address.street - self[:address_city] = @address.city - - @address = address -end -</ruby> - * PostgreSQL default log level is now 'warning', to bypass the noisy notice messages. You can change the log level using the <tt>min_messages</tt> option available in your <tt>config/database.yml</tt>. * Add uuid datatype support to PostgreSQL adapter. -* <tt>update_attribute</tt> has been removed. Use <tt>update_column</tt> if you want to bypass mass-assignment protection, validations, callbacks, and touching of updated_at. Otherwise please use <tt>update_attributes</tt>. - * Added <tt>ActiveRecord::Migration.check_pending!</tt> that raises an error if migrations are pending. * Added <tt>#destroy!</tt> which acts like <tt>#destroy</tt> but will raise an <tt>ActiveRecord::RecordNotDestroyed</tt> exception instead of returning <tt>false</tt>. |
