如何拥有与嵌入式关系的永恒关系 [英] How to have hasOne relation with embedded always relation

问题描述

EmberJS已在之前的修订版中删除了hasOne。创建这样一个嵌套的对象关系的方式是什么我想要有一个

EmberJS has removed hasOne in the earlier revision. Whats the way to create such a nested object relation where I want to have hasOne

删除hasOne已经完成了有利于belongsTo，任何人都可以分享一下如何在嵌套的JSON中写入{embed：always}关系。

Removal of hasOne has been done in favor of belongsTo, can anyone share a thought on how to write {embedded : always} relation between nested JSON.

推荐答案

我知道这个问题是旧的并回答，但由于它是ember hasone的顶级
搜索结果之一，我想分享我的调查结果。
我已经阅读了第一个答案中的链接，但这个例子有点过时了。

I know that this question is old and answered, but since it is one of the top search results for "ember hasone" i wanted to share my findings on the subject. I've read the link in the first answer but the example is kinda outdated.

嵌入式标志是过时的，DS.RESTAdapter.map不是一个函数，并且不建议使用DS.hasOne方法。

The "embedded" flag is obsolete, "DS.RESTAdapter.map" is not a function and the "DS.hasOne" method deprecated.

目前用于模拟hasOne关系的1.0.0-beta.2解决方案只是使用DS.belongsTo。他们没有很大的不同，你只需要将hasOne外键添加到你的结果集中，就像你对belongsTo一样。

The current 1.0.0-beta.2 solution for emulating the "hasOne relationship" is simply using "DS.belongsTo". They are not very different and you just need to add the hasOne foreignKeys to your result-set just like you would with belongsTo.

这是一个来自复杂模型的服务器响应示例。

Here's an example server response from a complex model.

{"users": [{
  "id": 1,
  "name": "John Doe",
  "profile": 27,        // merged hasone
  "image": 3,           // merged hasone
  "account_id": 64      // an actual belongsTo
}]}

然后作为模型

App.User = DS.Model.extend({
   name: DS.attr('string'),
   profile: DS.belongsTo('profile'),
   image: DS.belongsTo('image'),
   account_id: DS.belongsTo('account')
});

希望这有助于任何人寻找有关如何建模hasOne的信息
