Batch transaction save

batch.js

App.profileEditorController = Em.ObjectController.extend({
  addressBinding: 'content.address'
});

App.Router = Em.Router.extend({
  root: Em.Route.extend({

    profile: Em.Route.extend({
      route: 'profile',

      edit: Em.Route.extend({
        route: 'edit',

        connectOutlets: function(router) {
          router.get('applicationController').connectOutlet('profileEditor', router.get('currentUser'));
        },

        save: function(router) {
          var transaction = router.get('store').transaction(),
              user = router.getPath('profileEditorController.content'),
              address = user.get('address');

          transaction.add(user);
          transaction.add(address);
          transaction.commit();
          transaction.then(function(){
              router.transitionTo('profile')
          }, function(){
              // Do somphing on error
          });

          // OR OTHER PROMISE API LIKE:

          transaction.done(function(){
              router.transitionTo('profile')
          });
          transaction.fail(function(){
              // Do somphing on error
          });
        }
      })
    })
  })
});

Hi Luke,

I was wondering how we could add multiple association in the save function or elsewhere using router version 2. Just to continue with your code sample since the idea is thesame of adding the associated models in the save evet in the router's events hook :

 save: function(author) {

     user = router.getPath('profileEditorController.content'),
      post = this.controllerFor('post.content');
      comment = post.get('comments');

      transaction.add(post);
       transaction.add(comment);
       transaction.commit();
 }

This also doe not work:

 save: function(author){
     author.one('didCreate', this, function(){
        this.transitionTo('post.index'); 
    }); 

    var post = this.controllerFor('post').get('model');
     var comment = post.get('comments');

    this.get('currentModel.transaction').add(post);
     this.get('currentModel.transaction').add(comment);

       author.get('transaction').commit();
   }

Though it will save, the association are not added in the created record. What do I need to change. Thanks
