How to filter a model by belongsTo relationship property in EmberJS

I'm trying to filter a findAll query to get only the elements without relationship.

My model is created by two classes:

Element

export default Model.extend({
    position: attr('number'),
    name: attr('string'),
    shared: attr('boolean', { defaultValue: false }),
    stack: belongsTo('stack')
});

 Stack

export default Model.extend({
  position: attr('number'),
  name: attr('string'),
  shared: attr('boolean', { defaultValue: false }),
  element: hasMany('element')
});

I have tried to filter by property stack filterBy('stack', null) and filterBy('stack.content', null) but they didn't run.

Any idea and help of how to filter by relationships?

After looking for information, the solution is this:

var elements = new Ember.RSVP.Promise(function(resolve) {
  that.store.findAll('element').then(function(elements) {
    resolve(elements.filterBy('stack.content', null));
  })});

If you need to get the element that is in the relationship, you need to access to content attribute in order to be able to compare the value.
