Ember数据将primaryKey从id更改为其他内容 [英] Ember data changing primaryKey for a model from id to something else

问题描述

目前我有一个这样的模型设置

Currently I have a model setup like this

App.Specialty = DS.Model.extend({
    //specialty_id: attr(),
    name: attr()
});

它有一个primaryKey从json api返回，名为 specialty_id 而不是 id （ember数据可能预期的）。

It has a primaryKey being returned from the json api called specialty_id instead of id (what ember data probably expects).

所以没有任何垃圾数据获取两个对象，其中一个使用id作为任何参数，第二个对象获取正确的对象，但具有未定义的id。

So not fiddling with anything ember data gets two objects where one it uses the id as whatever parameter and the second one it gets the right object but has id as undefined.

我如何让余烬数据知道应该搜索 specialty_id ？

How can I let ember data know that it should be searching for specialty_id instead?

推荐答案

对于整个应用程序

App.ApplicationSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});

单一类型

App.FooSerializer = DS.RESTSerializer.extend({
  primaryKey: '_id'
});

您仍然将它称为 id 在模型中，但Ember Data将在传输期间将其序列化/反序列化为 _id 。

You will still refer to it as id on the model, but Ember Data will serialize/deserialize it to _id during transfer.
