【问题描述】：

我将 Laravel 4 与 emberjs 一起使用，我需要在 emberjs 应用程序上列出关系数据的集合，但 L4 打印集合有点不同，因此，我正在尝试更改 REST 序列化，但现在没有工作.. 我的 Ember Data 版本是 1.0.0-beta.7+canary.238bb5ce。有人帮忙吗？

我的 JSON 数据：

{
"names": [
{
    "id": "1",
    "description": "List 2014",
    "user_id": "3",
    "squares": [
    {
        "id": "1"
    }
    ]
}
],
"squares": [
{
    "id": "1",
    "name": "squa1",
    "role_id": "1"
    },
    {
        "id": "2",
        "name": "squa2",
        "role_id": "1"
    }
    ]}

我的models.js：

App.NameSerializer = DS.RESTSerializer.extend({
     primaryKey: 'id',
    extractArray: function(store, type, payload, id, requestType) {
        var posts =payload.names;
        var squares = [];
        payload.names[0].description = payload.names[0].description+"!!!";
        the = payload;


        posts.forEach(function(post){
               var reporter = post.squares,
                   reporterId = reporter.id;

                squares.push(reporter);
                post.reporter = reporterId;
        });

        payload.squares = squares;

        return this._super(store, type, payload, id, requestType);
    }
});



App.Name = DS.Model.extend({
    description: DS.attr('string'),
    squares: DS.hasMany('square'),
});
App.Square = DS.Model.extend({
    name: DS.attr('string'),
});

【解决方案1】：

到目前为止，json 的唯一问题是正方形数组ids。

"squares": [ { "id": "1" } ]

Ember 数据正在等待

"squares": [ "1" ]

这可以很容易地按照您所采取的方式进行补救

App.NameSerializer = DS.RESTSerializer.extend({
    primaryKey: 'id', // note this isn't necessary, the primary key is id by default
    extractArray: function(store, type, payload, id, requestType) {
      payload.names.forEach(function(name){
        var validSquareIdArray = [];
        name.squares.forEach(function(square){
          validSquareIdArray.push(square.id);
        });
        name.squares = validSquareIdArray;
      });

        return this._super(store, type, payload, id, requestType);
   }
});
