*About:* http://stonean.com/wiki/classy-inheritance Classy Inheritance simplifies the definition and implementation of one object depending on another object. For example, a User object depending on a Person object. If you do the following: class User < ActiveRecord::Base depends_on :person, :attrs => [:first_name, :last_name, :email] end You will get @user.first_name, @user.last_name and @user.email functionality. So, direct usage of these attributes can be used on your form and the Person associated is created/maintained for you. e.g.: <% text_field :user, :first_name %> Classy Inheritance also supports polymorphic associations, more info on the wiki. *In this release*: Added two options for the depends_on call: *validates_presence_if, validates_associated_if.* These options allow you to determine if/when the validation is called. Validation is on by default. There is a wiki, forum and issue tracking for Classy Inheritance at http://stonean.com thanks, andy -- Andrew Stone --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
