This plugin uses the conductor pattern to wrap multiple models as one object. It's basically like the Presenter pattern, but for saving and creating multiple models. For more information, please read the blog post Presenters & Conductors on Rails.
This plugin is built on top of Rails 3 ActiveModel. For a Rails 2 compatible version, see the Conductor plugin.
Install the gem:
gem install active_conductor
Add it to your Gemfile:
Install as a Rails plugin:
rails plugin install git://github.com/netzpirat/active_conductor.git
You can browse the API documentation directly on rdoc.info.
class SignupConductor < ActiveConductor def models [user, profile] end def user @user ||= User.new end def profile @profile ||= Profile.new end conduct :user, :first_name, :last_name conduct :profile, :image end conductor = SignupConductor.new conductor.first_name = "Scott" conductor.last_name = "Taylor" conductor.first_name #=> "Scott" conductor.user.first_name #=> "Scott" conductor.save conductor.valid? #=> false conductor.errors #=> [["photo", "is not valid"]]
