I would like to register multiple parties at once and each party can have multiple sub_parties.
With code above sub_parties are not created since they dont belogn to the correct hash when submitted to controller

here what i get in the controler params hash


"parties"=>{"party"=>{"0"=>{"created_at"=>"2010-11-11 00:00:00 +0100", "game_id"=>""}, "1"=>{"created_at"=>"2010-11-11 00:00:00 +0100", "game_id"=>""}, "2"=>{"created_at"=>"2010-11-11 00:00:00 +0100", "game_id"=>""}, "sub_parties_attributes"=>{"0"=>{"created_at"=>"2010-11-11 00:00:00 +0100", "game_id"=>""}, "1"=>{"created_at"=>"2010-11-11 00:00:00 +0100", "game_id"=>""}}}}, "controller"=>"parties", "party"=>{"game"=>{"1289474165"=>""}}

the parties part is ok but sub_parties should be in each parties.

The app is a rails 2.3 apps not 3

If somebody can helps me with that

parties_controller.rb

  def new
    @date = params[:date].to_date
    @extensions = Game.extensions.find(:all)
    @parties = []
    3.times do
      p = current_account.parties.build(:created_at => @date)
      2.times do
        p.sub_parties.build(:created_at => @date)
      end
      @parties << p
    end
    
    respond_to do |format|
      format.js
    end
  end

party.rb

class Party < ActiveRecord::Base
  validates_presence_of :game_id, :account_id
  belongs_to :game
  belongs_to :account
  has_many :players, :dependent => :destroy
  has_many :sub_parties, :dependent => :destroy, :class_name => "Party"
  accepts_nested_attributes_for :sub_parties
  after_create :up_partie_cache, :update_played_date
  after_destroy :down_partie_cache
  
  //parties methods here

end
