Ember.js 保存时具有多个关系拒绝的新模型

当我保存新模型时，它会拒绝，但记录实际上已保存。它错误地拒绝：

ember 2.0.2
ember-data 2.0.1

它尝试设置已销毁关系对象的长度属性。 我的代码如下：

//models/region.js

//models/question-list.js

export default Model.extend({
  regionName: attr('string'),

  questionList: belongsTo('question-list')
});

//一些哈佛商学院

export default Model.extend({
  name: attr('string'),

  regions: hasMany('region')
});

//components/some-multiple-select-component.js

{{some-multiple-select-component content=regions value=questionList.regions labelPath="regionName"}}

目前，我的解决方法如下：

export default Ember.Component.extend({
  tagName: 'select',

  _setup: Ember.on('didInsertElement', function() {
    const component = Ember.$(this.get('element'));

    component.select2({
      placeholder: this.get('placeholder'),
      data: this._prepareData(),
      multiple: true
    });

    component.on('select2:select', Ember.run.bind(this, this._select));
    component.on('select2:unselect', Ember.run.bind(this, this._unselect));
  }),

  _rerender: Ember.on('didRender', function() {
    const component = Ember.$(this.get('element'));
    const preparedData = this.get('value').mapBy('id');

    component.val(preparedData).trigger('change');
  }),

  _prepareData() {
    const content = this.get('content');

    return content.map(item => {
      return {
        id: item.get('id'),
        text: item.get(this.get('labelPath'))
      };
    });
  },

  _select(event) {
    this.get('value').addObject(this._getEventedObject(event));
  },

  _unselect(event) {
    this.get('value').removeObject(this._getEventedObject(event));
  },

  _getEventedObject(event) {
    const valueId = event.params.data.id;
    return this.get('content').findBy('id', valueId);
  }

});

我相信我的组件中存在这个问题，但我应该如何正确地处理它。

错误消息似乎非常清楚：错误：断言失败：调用已销毁对象上的集合。。在代码中的某个地方，您似乎正在为一个已被破坏的模型设置一个值。@JonKoops是的，我理解这一点，我知道它就在这个组件中。这是因为当我删除它时，错误消失了。但我不知道它在哪里。

questionList.save().finally(() => {
  if (record.get('id')) { do something }
});
