在ember数据1.0.0 beta 14.1中，hasMany关系的有效载荷应该是什么样的？

I have a model with hierarchical relation like this:

我有一个像这样的层次关系的模型：

 App.Question=DS.Model.extend({
  name:DS.attr('string'),
  childQuestions:DS.hasMany('question',{async:true}),
  parentQuestion:DS.attr('string')
});

My payload looks like this :

我的有效负载如下所示：

"questions":[
  {
    id:1,
    name:'question 1',
    childQuestions:[]
  },
  {
    id:2,
    name:'question 2',
    childQuestions:[3]
  },
  {
    id:3,
    name:'question 3',
    childQuestions:[],
    parentQuestion:2
  }
]

before with ember 1.5 and ember data beta 3, I was able to do :

在使用ember 1.5和ember数据beta 3之前，我能够做到：

var q = model.findBy('id','2');
console.log(q.get('childQuestions'));//would give me promiseArray with the child questions

but the same returns empty promise array that has nothing even when it resolves!!

但同样返回空的promise数组，即使它结算也没有任何内容！

Code with ember 1.5.0 and data-data 1.0.0 beta 3 : http://emberjs.jsbin.com/zeqomitapi/1/

使用ember 1.5.0和数据数据1.0.0 beta 3的代码：http：//emberjs.jsbin.com/zeqomitapi/1/

Code with ember 1.9.1 and data-data 1.0.0 beta 14.1 : http://jsbin.com/koyiqocoyi/1/

代码包含ember 1.9.1和data-data 1.0.0 beta 14.1：http：//jsbin.com/koyiqocoyi/1/

I could probably try out "EmbeddedRecordsMixin" but at this point we don't want to change anything in the rest api itself.

我可能会尝试“EmbeddedRecordsMixin”，但此时我们不想改变其余api本身的任何内容。

Your help will be highly appreciated. Thanks.

我们将非常感谢您的帮助。谢谢。

Ember Data wants you to configure the parentQuestion relationship as a DS.belongsTo:

Ember Data希望您将parentQuestion关系配置为DS.belongsTo：

App.Question=DS.Model.extend({
  name:DS.attr('string'),
  childQuestions:DS.hasMany('question',{async:true}),
  parentQuestion:DS.belongsTo('question')
});
