我在卸载数据模型并在进行API调用时正确地重新填充它们时遇到了麻烦。
型号：

/* Model Foo */
export default DS.Model.extend({
  bars: DS.hasMany('bar', { async: true })
});

/* Model Bar */
export default DS.Model.extend({
  foo: DS.belongsTo('foo', { async: true, inverse: 'bars' })
});

在应用中的某个点，foo和bar都从ember数据存储中卸载，然后从API调用中重新加载。

/* Unload and reload snippet */
this.store.unloadAll('bar');
this.store.unloadAll('foo');

let bars = this.store.filter('bar', { 
  queryParam: x 
}, function(bar) {
  return x === bar.x
});

let foos = this.store.filter('foo', { 
  queryParam: y 
}, function(foo) {
  return y === bar.y
});

let self = this;
Ember.RSVP.all([foos, bars]).finally(function() {
  self.controller.set('model.foos', foos);
  self.controller.set('model.bars', bars);
});

问题出现在依赖于这些模型变化的计算属性中。

/* Computed property elsewhere in app */
compProp: Ember.computed('foo.bars.[]', function() {
  let tmp = this.get('foo.bars'); /* <-- Error generating line */
  .
  .
  .
})

这一行给出了以下错误：Assertion Failed: calling set on destroyed object: <DS.PromiseManyArray:ember1995>.content = <DS.ManyArray:ember3320>
来自错误的堆栈跟踪：

Assertion Failed: calling set on destroyed object: <DS.PromiseManyArray:ember1014>.content = <DS.ManyArray:ember1348>

谢谢你的帮助！
附注：

• 我知道store.filter()已经过时了。我正在从早期的Ember版本升级应用程序，并使用ember-data-filter插件来临时兼容。
• 这在Ember 1.13上是有效的。

更新

为了不让这个问题悬而未决，我从来没有能够找到这个问题。
对我来说，解决方案是删除所有unloadAll()呼叫，并根据需要单独管理记录。
