我正在使用Ember RC6.1和Ember Model。当我将模型类的adapter属性设置为 Ember 模型类的实例RESTAdpater并执行 afindAll时，将为添加到生成的 Ember 数组的每个对象引发一个断言。堆栈跟踪显示对象被压入数组，插入，然后替换。我不确定为什么会发生后者（替换）。这可能是隐式排序的结果。

对于每次推送，都会抛出一个断言，声明（继承自）content的实例的属性应在修改之前设置。RecordArrayArrayProxy

Assertion failed: The content property of Ember.RecordArray should be set before modifying it

结果数组表现正常，但我想知道这是 Ember 模型还是 Ember 本身的错误。我假设我的代码不对这个错误负责，因为除了根据 Ember 模型的文档从 API 获取数据之外，我没有做任何不寻常的事情。

我在下面添加了堆栈跟踪。

更新：调用pushObject由 Ember 模型执行。我添加了 的实现addToRecordArrays，该方法将记录添加到 的实例中RecordArray。

addToRecordArrays: function(record) {
  if (this._findAllRecordArray) {
    this._findAllRecordArray.pushObject(record);
  }
  if (this.recordArrays) {
    this.recordArrays.forEach(function(recordArray) {
      recordArray.pushObject(record);
    });
  }
}
