Question

我已经建立了两个具有很多关系的模型

// app/models/userwelcome.js
export default DS.Model.extend({
  favorites:DS.hasMany('favorite'),
  brandcredits:DS.attr(),
  token: DS.attr('string'),
  fullname:DS.attr('string'),
  userimglocation:DS.attr('string'),
  city:DS.attr('string'),

 });

和

// app/models/favorite.js
export default DS.Model.extend({

  Brandname: DS.attr('string'),
  Imglocation: DS.attr('string'),
  Checked:DS.attr('string'),
  Createdate:DS.attr('date'),
  userwelcome: DS.belongsTo('userwelcome')

});

我通过我的服务器的sideloaded json引导记录，如下所示 -

{ userwelcome: 
   [ { _id: 558ce2af106319b412e48b67,
       userimglocation: '/images/user_imgs/ppl5.jpg',

记录已加载但我想知道如何从我的userwelcome路线中的模型收藏夹访问数据。我正在设置我的userwelcome路线如下 -

  model: function() {
   var token=this.controllerFor('index').get('token');

    console.log(token);

    var self=this;

    var inflector = Ember.Inflector.inflector;
    inflector.irregular('userwelcome', 'userwelcome');
      return this.store.find('userwelcome',{'token':token});


  }

我可以从userwelcome模型访问字段，但如何从喜欢的模型中访问字段？

有很多选项，例如，您可以使用store.all：

// route
var self = this;
model: function() {
   // ...
   return this.store.find('userwelcome',{'token':token}).then(function(records) {
     return Ember.RSVP.hash({
       model: records,
       favorites: self.store.all('favorite');
     });
   });
},

setupController: function(controller, models) {
  controller.setProperties(models);
}

// template
{{#each favorites as |f|}}
  {{!-- ... --}}
{{/each}}

在ember cli中从路由器访问不同的模型
