Ember.js Get model length without call 'findAll()'

I find a method for get model length.

I tried to use findAll method.

```

export default Ember.Route.extend({
    model() {
      console.log("CHECK MODEL");
      let texts = this.store.findAll('text');
    }
});

```

why return 0?

How can I get a model length with out using findAll method?
