Ember howto use model field values in Controller - ember.js

Question

I am a newbie on Ember and break my head already a couple of hours how i can use the value of a model field in a controller ?
This is my model :
import DS from 'ember-data';
export default DS.Model.extend({
id_customer: DS.attr('number'),
id_default_group: DS.attr('number'),
id_lang: DS.attr('number'),
id_gender: DS.attr('number'),
active: DS.attr('boolean'),
email: DS.attr(),
firstname: DS.attr(),
lastname: DS.attr(),
company: DS.attr(),
birthday: DS.attr('date'),
date_add: DS.attr('date'),
date_upd: DS.attr('date'),
max_payment_days: DS.attr('number'),
newsletter: DS.attr('boolean'),
note: DS.attr(),
website: DS.attr()
});
This is my route :
import Ember from 'ember';
export default Ember.Route.extend({
beforeModel: function(){
if(!this.get('session.isAuthenticated')){
this.transitionTo('application');
}
},
model(params) {
return Ember.RSVP.hash({
customer: this.store.findRecord('customer', params.id),
address: this.store.query('address', {
orderBy: 'id_customer_fb',
equalTo: parseInt(params.id)
})
});
}
});
This is my controller :
import Ember from 'ember';
const genders = [
{ title: 'Dhr.', id_gender: '1' },
{ title: 'Mevr.', id_gender: '2' },
];
export default Ember.Controller.extend({
genders: genders,
selection: genders[1]**, <== THIS '1' MUST BE REPLACED WITH THE VALUE OF models.customer.id_gender ?????**
actions: {
chooseDestination(genders) {
this.set('selection', genders);
},
}
});
I would that the value 1 in this genders array could be the value of model.customer.id_gender ?

Answer 1

Yes you can.
Change selection like this :
selection: Ember.computed(function(){
let ret = this.get('genders').filterBy('id_gender', this.get('model.customer.id_gender'));
return ret.objectAt(0);
})
