Saving nested objects with Rails, backbone.js, and accepts_nested_attributes_for

Question

I\'m using Rails, backbone.js (learning this now). Let\'s say you have two models, Car and Engine.

var Car = Backbone.Model.extend({
  initialize: function(         


        

Answer 1

I would suggest to override toJSON on the backbone model.

toJSON: function(){

  json = {car : this.attributes};
  return _.extend(json, {engine_attributes: this.get("engine").toJSON());

}

toJSON is called within the sync method just before sending data to the backend.
