javascript - Extjs 5，数据模型关联&加载嵌套数据

Question

努力使这项工作....

我想在两个对象模型上加载嵌套数据

Ext.application({
name : 'MyApp',

launch : function() {


    Ext.define('MyApp.model.Address', {
        extend: 'Ext.data.Model',

        entityName: 'Address',

        fields: [ 

            {
                name: 'id',
                type: 'int'
            },
            {
                name: 'addressLine',
                type: 'string'
            },
            {
                name: 'city',
                type: 'string'
            },
            {
                name: 'created',
                type: 'date',
                dateFormat: 'time',
                persist: false
            }
        ]
    });


    Ext.define('MyApp.model.User', {
        extend: 'Ext.data.Model',

        entityName: 'User',

        fields: [ 
            {
                name: 'id',
                type: 'int'
            },
            {
                name: 'address',
                reference: 'Address'
            },
            {
                name: 'name',
                type: 'string'
            },
            {
                name: 'lastname',
                type: 'string'
            },
            {
                name: 'created',
                type: 'date',
                dateFormat: 'time',
                persist: false
            }
        ]
    });


    var user = new MyApp.model.User({
        "id": 1,
        "name": "Pedro",
        "lastname": "Carbonell",
        "address": {
            "id": 1,
            "addressLine": "Bailen 22",
            "city": "Barcelona",
            "created": 1420668866000
        },
        "created": 1420668866000
    });        

    console.info(user);
    console.info(user.getAddress());

}});

创建用户时没有错误，但是当我通过 user.getAddress() 访问关联数据时，它返回了一个异常:

 Uncaught Error: The model ID configured in data ("[object Object]") has been rejected by the int field converter for the id fieldext-all-debug.js

尝试在模型定义上定义像 memory 或 localstorage 这样的代理，但结果是一样的。

已解决，但只找到这个解决方案:当使用 loadRawData...

    var store = new Ext.data.Store({
        model: MyApp.model.User
    });

    store.loadRawData({
        "id": 1,
        "name": "Pedro",
        "lastname": "Carbonell",
        "address": {
            "id": 1,
            "addressLine": "Bailen 22",
            "city": "Barcelona",
            "created": 1420668866000
        },
        "created": 1420668866000
    });        

    console.info(store.first());
    console.info(store.first().getAddress());

你是对的，ext有点不稳定，非常....
