带有代理的extjs树存储

Question

我正在创建一个MVC extjs应用程序。我有一个带有商店的treepanel，它正在从php源加载数据。我收到以下json格式的响应：

[
{
    "text": "Home",
    "leaf": true,
    "dbName": "NULL",
    "children": []
},
{
    "text": "Moje Firma s.r.o.",
    "leaf": false,
    "expanded": false,
    "children": [
        {
            "text": "Vydane",
            "leaf": true,
            "dbName": "demo"
        },
        {
            "text": "Prijate",
            "leaf": true,
            "dbName": "demo"
        }
    ]
},
{
    "text": "Já Živnostník",
    "leaf": false,
    "expanded": false,
    "children": [
        {
            "text": "Vydane",
            "leaf": true,
            "dbName": "demo_de"
        },
        {
            "text": "Prijate",
            "leaf": true,
            "dbName": "demo_de"
        }
    ]
},
{
    "text": "Nezisková organizace",
    "leaf": false,
    "expanded": false,
    "children": [
        {
            "text": "Vydane",
            "leaf": true,
            "dbName": "demo_neziskova"
        },
        {
            "text": "Prijate",
            "leaf": true,
            "dbName": "demo_neziskova"
        }
    ]
},
{
    "text": "P?ísp?vková organizace",
    "leaf": false,
    "expanded": false,
    "children": [
        {
            "text": "Vydane",
            "leaf": true,
            "dbName": "demo_prispevkovka"
        },
        {
            "text": "Prijate",
            "leaf": true,
            "dbName": "demo_prispevkovka"
        }
    ]
},
{
    "text": "Moje Firma SK s.r.o.",
    "leaf": false,
    "expanded": false,
    "children": [
        {
            "text": "Vydane",
            "leaf": true,
            "dbName": "demo_sk"
        },
        {
            "text": "Prijate",
            "leaf": true,
            "dbName": "demo_sk"
        }
    ]
}
]

我的商店：

Ext.define('Statistics.store.Menu', {
extend: 'Ext.data.TreeStore',
model: 'Menu',
autoLoad: true,
autoSync: true,

proxy   : {
    type : 'ajax',
    url  : 'data.json',
    reader: {
        type: 'json'
    }
}


});

和型号：

Ext.define('Statistics.model.Menu', {
extend: 'Ext.data.Model',

fields: [
    {name: 'text', type: 'string'},
    {name: 'leaf', type: 'boolean'},
    {name: 'expanded', type: 'boolean', defaultValue: false},
    {name: 'dbName', type: 'string', defaultValue: 'NULL'}
],

});

当数据保存在.json文件中时，此配置有效。但是，当从php源加载ID时，它们不起作用。

感谢您的任何答复。

服务器响应必须如下所示：

{
   success: true,
   children: // here is the array of items
}
