ember.js - Ember Simple Auth - 将当前用户注入(inject)每条路由

Question

我正在使用 Ember Simple Auth 构建一个站点。

我关注了these instructions尝试将当前用户对象添加到 session 中，并且它使用了这个稍微修改过的代码:

import Ember from 'ember';
import Session from 'simple-auth/session';

export default {
  name: "current-user",
  before: "simple-auth",
  initialize: function(container) {
    Session.reopen({
      setCurrentUser: function() {
        var accessToken = this.get('secure.token');
        var _this = this;
        if (!Ember.isEmpty(accessToken)) {
          return container.lookup('store:main').find('user', 'me').then(function(user) {
            _this.set('content.currentUser', user);
          });
        }
      }.observes('secure.token'),
      setAccount: function() {
        var _this = this;
        return container.lookup('store:main').find('account', this.get('content.currentUser.account.content.id')).then(function(account) {
          _this.set('content.account', account);
        });
      }.observes('content.currentUser'),
    });
  }
};

但是，使用最新版本的 Ember，我得到以下信息:

DEPRECATION: lookup was called on a Registry. The initializer API no longer receives a container, and you should use an instanceInitializer to look up objects from the container. See http://emberjs.com/guides/deprecations#toc_deprecate-access-to-instances-in-initializers for more details.

我知道我需要将以上内容拆分为/app/initializers 和/app/instance-initializers (根据注释 here )，但我不太确定如何去做。

当然，如果有一种更简单/更清洁的方法可以使用户和帐户对象可用于每个路由/模板，我很乐意听到它们:)

谢谢

Answer 1

这对我有用:

ember-cli:0.2.7(ember:1.12.0，ember-data:1.0.0-beta.18)

ember-cli-simple-auth: 0.8.0-beta.3

注:

Ember 数据:1.13。存储在初始化程序中注册，应该按原样工作

Ember 数据:1.0.0-beta.19。存储在实例初始化器中注册，需要一些调整

1) 自定义 session

//config/environment.js
ENV['simple-auth'] = {
  session: 'session:custom',
  ...
}

//app/sessions/custom.js
import Session from 'simple-auth/session';

export default Session.extend({

  // here _store is ember-data store injected by initializer
  // why "_store"? because "store" is already used by simple-auth as localStorage
  // why initializer? I tried 
  // _store: Ember.inject.service('store') and got error

  currentUser: function() {
    var userId = this.get('secure.userId');
    if (userId && this.get('isAuthenticated')) {
      return this._store.find('user', userId);
    }
  }.property('secure.userId', 'isAuthenticated')

});

2)通过初始化程序将存储注入(inject) session (否则 find() 将不起作用)

//app/initializers/session-store
export function initialize(container, application) {
  application.inject('session:custom', '_store', 'store:main')

  // "store:main" is highly dynamic depepeding on ember-data version
  // in 1.0.0-beta.19 (June 5, 2015) => "store:application"
  // in 1.13 (June 16, 2015) => "service:store"
}

export default {
  name: 'session-store',
  after: 'ember-data',
  initialize: initialize
}

3) 在模板中

{{#if session.isAuthenticated}}
  {{session.currentUser.name}}
{{/if}}

注意:这并不能使您摆脱由 ember-simple-auth 产生的弃用。本身。
