Hello, I have order model that has many lines. I would like to create order only when all order lines will be created:
require 'rubygems' require 'activeresource' class PurchaseOrder < ActiveResource::Base self.site = "http://admin:secret@localhost:23456" end o = PurchaseOrder.create(:account_ref => '123', :lines => [{ :code => "111" }, {:code => "222"}]) puts o.inspect
If I add validation that code has to be <200, then the PurchaseOrder should never be created.
The problem is, I am not aware of the rails way of doing it 
I started directing towards doing custom validation before after_create with this code:
class PurchaseOrder < ActiveRecord::Base has_many :purchase_order_lines
attr_accessor :new_lines
def lines=(_lines) @new_lines ||= _lines.each do |_line_params| puts _line_params.inspect @new_lines << PurchaseOrderLine.new(_line_params) end end
after_create :store_lines
def store_lines new_lines.each do |line| line.purchase_order = self line.save! end end end
However this does not seem elegant. How can I do it, so that the creation is done in one call and less custom code needs to be written?
