Hi guys,

As you can see at those links:

- [How to create a duplicate of an object (obj.dup)](http://discuss.emberjs.com/t/how-to-create-a-duplicate-of-an-object-obj-dup/3259)

- [Ember.js Clone an existing record into the store - Stack Overflow](http://stackoverflow.com/questions/20477301/ember-js-clone-an-existing-record-into-the-store)

- hxxp://stackoverflow.com/questions/20007049/how-can-i-clone-an-ember-data-record-including-relationships

- hxxp://stackoverflow.com/questions/14912425/ember-clone-model-for-new-record

As you can see all those questions are not answered. There is still need for documentation of code examples for copying/cloning an object in Ember Data.

What I still have so far is the following which does cloning of all attributes except hasMany items. And the drawback is that belongsTo items have to be done by hand.

```
var myItem= this.get('model').toJSON(),
	self = this;

// todo implement getting hasMany items

// set belongsTo items by hand
myItem['someAttr'] = this.get('someAttr');
myItem['someAttr1'] = this.get('someAttr1');
myItem['someAttr2'] = this.get('someAttr2');

var duplicatedItem= this.store.createRecord('item', myItem);

```

So there are some points to improve:

1. Saving of belongsTo not by hand
2. Saving of hasMany items

A little new bump to get attention…

I was the one posting the original question at [ember.js - Ember clone model for new record - Stack Overflow](http://stackoverflow.com/questions/14912425/ember-clone-model-for-new-record)

I have updated my answer there with a method I’m currently using. Maybe there’s a better way of handling the async nature of hasMany?

At least it’s handling belongsTo dynamically.
