Javascript 为什么余烬数据认为save（）失败了，而事实并非如此？

我有一个余烬模型，我正在保存到数据库中。当我打电话时

model.save().then(function () {
  alert('Everything worked.');
}, function () {
  alert('Save failed.');
});

记录保存到数据库，对执行保存的API调用的网络请求以状态代码200和一个

{
  "id": 11,
  "send_date": "2014-12-01T23:20:31.821Z",
  "expiration_date": "2014-12-08T06:00:00.000Z",
  "message": "What is happening here",
  "url": null,
  "feature_id": null
}

控制台中不会出现任何错误。除了每次都调用拒绝处理程序警报“Save failed.”之外，所有操作都可以正常工作。从未调用成功处理程序。为什么?

传递给失败处理程序的原因是以下错误：

我现在通过从Ember数据模型中删除一个belongsTo关系来修复这个错误。这种关系是为了我稍后将要实现的一个特性，所以我现在要删除它。我想当我到达那座桥时，我会穿过它。

你能试试这个：}，functionreason alertreason；}？JSON响应是否需要与模型类型同名？如果在devtools中启用“捕获异常时暂停”，则可能会在flagrante delicto中看到问题。
