Is there an always callback for Ember.js .then function?

Question

Assume I got an Ember obj. When doing any kind of sync with backend there is a possiblity to use a promise chain:

obj.save().then(function(res){
  // Success callback
}, function(res){
  // Fail callback
});

Is there a done/always callback for Ember.js promise chain with .then()?

I've tried adding a third parameter function, but it did not help.

http://emberjs.com/api/classes/Ember.PromiseProxyMixin.html#method_finally

Ember -> jQuery

1. .then() -> .done()
2. .catch() -> .fail()
3. .finally() -> .always()

Example (in the router):

var self = this;
var modelType = this.store.createRecord('modelType', {/* model attrs */});

modelType.save().then(function(model){
  self.transitionTo('model.show', model);
}).catch(function(){
  console.log('Failure to Save: ', reason);
}).finally({
  self.hideSpinner()
});

Unfortunately there isn't. But you can create your own modifying the RSVP.Promise prototype:

Ember.RSVP.Promise.prototype.always = function(func) {
  return this.then(func, func);
}

So you can do the following:

// will show success
Ember.RSVP.resolve('success').always(function(msg) { 
  alert(msg) 
})

// will show error
Ember.RSVP.reject('error').always(function(msg) { 
  alert(msg) 
})

I hope it helps
