如何在Ember-i18n中转换控制器成员数组？

Question

In my customer controller I have defined some constant arrays that are used for populating select input (dropdown) options.

import Ember from 'ember';

export default Ember.Controller.extend({
    occupations: [
        {code: 'student', name: "Student"},
        {code: 'worker', name: "Worker"},
        {code: 'retired', name: "Retired"},
        {code: 'other', name: "Other"}
    ]
});

Normal solution would be using translationMacro function t() or this.get('i18n').t() around translation key, but they can't be used in such situation as "this" inside object or array will not refer to controller.

What is best practice for solving such situation?

You can make occupations a property:

import Ember from 'ember';

export default Ember.Controller.extend({
    i18n: Ember.inject.service(),

    occupations: function() {
        var i18n = this.get('i18n');
        return [
            {code: 'student', name: i18n.t('occupations.student') },
            {code: 'worker', name: "Worker"},
            {code: 'retired', name: "Retired"},
            {code: 'other', name: "Other"}
        ];
    }.property()
});
