Question

我使用 Ember Model Ember RC6.1 。当我将模型类的adapter属性设置为Ember Model的RESTAdpater类的实例并执行findAll时，会为添加到生成的Ember数组的每个对象抛出一个断言。堆栈跟踪显示对象被推入阵列，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，指出在修改它之前应该设置content实例的RecordArray属性（继承自ArrayProxy）。

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

生成的数组表现正常，但我想知道这是否是Ember Model或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 Model的文档从API中获取数据之外我什么都不做。

我在下面添加了堆栈跟踪。

更新：对pushObject的调用由Ember Model执行。我添加了addToRecordArrays的实现，这是将记录添加到RecordArray实例的方法。

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

我已经恢复了引入此问题的提交。

为什么Ember在将物体推到Ember阵列时会抱怨？
