How to set the i18n.locale from within an initializer

问题

I would like to set 'i18n.locale' from within an initializer in EmberJS.

I am using 1.12 via Ember-CLI with ember-i18n.

I tried this

import Ember from 'ember';

export function initialize(container, application) {
  Ember.set('i18n.locale', 'de');
}

export default {
  name: 'user-locale',
  initialize: initialize
}

but am receiving Assertion Failed: Path 'i18n.locale' must be global if no obj is given.

You could get i18n as service:i18n and use instance-initializer to set i18n.locale.

//app/instance-initializers/user-locale.js
export function initialize(instance) {
  var i18n = instance.container.lookup('service:i18n');
  i18n.set('locale', 'de');
}

export default {
  name: 'user-locale',
  after: "ember-i18n",
  initialize: initialize
}

InstanceInitializers guides:

http://emberjs.com/blog/2015/05/13/ember-1-12-released.html#toc_instance-initializers

As of Ember 1.13.8 you now have to access the container as a function

const i18n = instance.container().lookup('service:i18n');
