ember.js - Ember js cloning record with relations -

what try achieve: user goes post/3/edit. here form bound model, filled out. , on top

you editing post {{model.title}} 

if user changes title changes dynamic. don't want behavior. want apply changes record, if user hit "save" button (and went right on server side).

my idea:

1. clone record
2. bind cloned record form
3. after hit "save" properties of cloned (and edited) record applied original record.

questions

• is right way this?
• is there record.clone(), deep copy record with it's relations?
• is there way apply changes, originalrecord.apply(clonedrecord)?

assuming using ember data:

an easier approach might use setupcontroller hook in post edit route:

// routes/posts/edit.js export default ember.route.extend({   setupcontroller: function (controller, model) {     this._super(controller, model);     this.controller.set('statictitle', model.get('title'));   } }); 

then in template:

{{statictitle}} 

then when submit form, reset static title new value after successful save:

// controllers/posts/edit.js . . . actions: {   savepost: function() {     var controller = this;     var post = this.get('model');     function onsuccess(savedpost) {       controller.set('statictitle', savedpost.get('title');       //transition somewhere     }     function onfailure() {       post.rollback()     }     post.save().then(onsuccess, onfailure);   } }
