Ember数据嵌入记录当前状态？ [英] Ember-data embedded records current state?

问题描述

我已经搜索整个网页，大部分的帖子是过时的其他人已经过时了+需要我使用第三方库或连线300行特殊代码有很多缺点。

我不知道如何使用嵌入式记录与ember数据今天站在一起？

编辑：现在有一个新的文档 http://emberjs.com/api/data/classes/DS.EmbeddedRecordsMixin.html

解决方案

使用 ActiveModelSerializer 可以包含 EmbeddedRecordsMixin 允许您使用嵌入式记录。 （在Canary版本1.0 Beta 9+中，您可以使用 JsonSerializer / RESTSerializer ）

Serializer

  App.ColorSerializer = DS.ActiveModelSerializer.extend（DS.EmbeddedRecordsMixin ，{
 attrs：{
 foos：{embed：'always'} 
} 
}）; 
  

模型

  App.Color = DS.Model.extend（{
 color：DS.attr（），
 foos：DS.hasMany（'foo'）
}）; 
 
 App.Foo = DS.Model.extend（{
 name：DS.attr（）
}）; 
  

JSON

  {
 colors：[
 {
 id：1，
 color：red，
 foos：[
 {
 id：1，
 name：'something 1'
}，
 {
 id：2，
 name：'something 2'
} 
] 
}，
 ...

对于 RESTSerializer 和 JsonSerializer ，它遵循相同的模式

  App.ColorSerializer = DS.RESTSerializer.extend（DS.EmbeddedRecordsMixin，{
 attrs：{
 foos：{embedded：'always '} 
} 
}）;

I am really stuck with tons of problems caused by Ember-data and it lacks of embedded records support.

I have searched the entire web, most of the posts are outdated others are outdated + requires me to use 3rd party libraries or to wire up 300 lines of special code with lots of drawbacks.

I've no idea how to use embedded records with ember-data as it stands today?

edit: there is a new documentation now http://emberjs.com/api/data/classes/DS.EmbeddedRecordsMixin.html

解决方案

Using the ActiveModelSerializer you can include the EmbeddedRecordsMixin which allows you to use embedded records. (In the canary versions, 1.0 beta 9+, you can use the JsonSerializer/RESTSerializer as well)

Serializer

App.ColorSerializer = DS.ActiveModelSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs: {
    foos: {embedded: 'always'}
  }
});

Models

App.Color = DS.Model.extend({
  color: DS.attr(),
  foos: DS.hasMany('foo')
});

App.Foo = DS.Model.extend({
  name: DS.attr()
});

JSON

{
 colors:[
  {
    id: 1,
    color: "red",
    foos:[
      {
        id:1,
        name:'something 1'
      },
      {
        id:2,
        name:'something 2'
      }
    ]
  },
  ...

For the RESTSerializer and JsonSerializer it follows the same pattern

App.ColorSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
  attrs: {
    foos: {embedded: 'always'}
  }
});
