The art of encapsulating JSON response objects in Ember Objects with a deep layer of wrapping

Currently, I am engaged in a project using Ember where I retrieve a complex JSON response in a Route's model function. In the associated template, I exhibit attributes of the response. Some of these attributes allow for specific actions that result in modifications to the model.

I aim to have these changes instantly reflected in the interface through Ember's binding feature. Regrettably, although accessing a top-level attribute from the JSON response in the ObjectController via this.get('attributeFromJson') is successful, attempting the same action on a child property does not yield the desired outcome.

To illustrate the issue, I have created the following JSFiddle: http://jsfiddle.net/KkD6U/

My understanding is that I must manually convert the response into an Ember.Object to leverage its Ember.Observable capabilities.

My question is: Is there a straightforward Ember method to automatically "deep-wrap" an entire JSON response into a structure comprised of Ember.Object instances for utilizing get and set across the entire response? How would one accomplish this in plain Ember?


Update:

Subsequently, I devised a basic function to transform regular JavaScript objects into Ember objects, view the jsFiddle here: http://jsfiddle.net/5vEcL/1/

Does this approach seem viable?

Answer №1

It seems to me that I'd have to manually convert the response into an Ember.Object in order to take advantage of its Ember.Observable mixin.

Yes, basically, if you wrap your child objects in Ember.Object.create(...), it will be compatible with ember's binding mechanism:

...
anArray: [
  Ember.Object.create({
    id: '1',
    anotherAttribute: '123'
  }),
  Ember.Object.create({
    id: '2',
    anotherAttribute: '456'
  })
]
...

I hope this explanation helps.
