未捕获错误：断言失败：您不能将`id`设置为模型的属性 [英] Uncaught Error: Assertion Failed: You may not set `id` as an attribute on your model

问题描述

整个错误：

Uncaught Error: Assertion Failed: You may not set `id` as an attribute on your model. Please remove any lines that look like: `id: DS.attr('<type>')` from App.Plan

Ember模型：

App.Plan = DS.Model.extend({
id: DS.attr('number'),
name: DS.attr('string'),
period: DS.attr('number'),
price: DS.attr('number')
});

来自REST API的数据：

Data coming from REST API:

{"plans":[{"id":1,"name":"Monthly subscription","period":1,"price":2}]}

问题：如何解决上述错误？

推荐答案

只需从 DS.Model id C $ C>。 Ember数据自动为您处理。您仍然可以使用id查找记录，并且当您从Ember应用程序中访问该对象时，它将是对象上的一个属性。 请参阅这里和 here 获取更多信息。

Just leave out the id attribute from your DS.Model. Ember-data automatically handles that for you. You'll still be able to find the record using the id, and it'll be a property on the object when you access it from within your Ember application. See here and here for more info.

App.Plan = DS.Model.extend({
  name: DS.attr('string'),
  period: DS.attr('number'),
  price: DS.attr('number')
});
