Rails - Jan 2006 - Saving or updating multiple models

Hello all,

I was wondering how one would create multiple models in one controller action.

Consider the following models:

class Worker < ActiveRecord::Base
   belongs_to :person
   belongs_to :user
   validates_presence_of :person_id
end

class Person < ActiveRecord::Base
   has_many :workers
end

class Client < ActiveRecord::Base
   has_many :workers
end

class User < ActiveRecord::Base
   # several validations
end

and the following controller_code:

class WorkersController < ApplicationController
   def create
      @worker = Worker.new(params[:worker])
      @worker.person = Person.new(params[:person])
      @worker.user = User.new(params[:user]) if @worker.is_contact

       if @worker.save
          # success
       else
          # failure
       end
   end
end


The problem as far as I can see here is, that the @worker model is
tried to be saved, without saving the children first.

Another thing is, when I do things like:

@worker.person.save
@worker.save

than the @worker doesn''t get saved because it doesn''t know the
@worker.person_id .

How to save multiple models from one controller respecting callbacks (
before_save, before_create, etc...) ?
