如何使用Ext.data.writer.Json创建一个应用了nameProperty的模型对象

I have nameProperty set in the proxy of my store like this : Code:

我在我的商店的代理中设置了nameProperty,如下所示:代码:

writer : {
        type : 'json',
        nameProperty : 'mapping',
        root : 'PerVO'
    }

And in my model , the mapping like this:

在我的模型中,映射如下:

        {
            name : 'modules',
            mapping : 'modules.collection',
            defaultValue: []
        },

This works fine when I call the CRUD operations on the store. Now I want to get the data in the format being sent to the server for other operations. The problem is that when I get the record from the store , the mapping is lost. So how can I useExt.data.writer.Json or some other api to generate the data EXACTLY as it would be generated while being sent to the server with mapping applied :

当我在商店调用CRUD操作时,这很好用。现在我想以格式将数据发送到服务器以进行其他操作。问题是,当我从商店获取记录时,映射将丢失。那么我怎样才能使用.NET.data.writer.Json或其他一些api来生成数据,因为它会在发送到应用了映射的服务器时生成:

This is what the store sends for save (I need the data like this. Note : Difference is 'collection:')

这是商店发送保存的内容(我需要这样的数据。注意:差异是'集合:')

    "modules": {
        "collection": {
            "isActive": 1,
            "metadata": {
                "actionCodes": "",
                "memos": ""
            },
            "moduleCode": "OM",
            "moduleId": 250,
            "moduleName": "Org Management",
            "success": false,
            "viewId": 0
        }
    },

This is what i get from the store when the record is looked up:

这是我在查找记录时从商店获得的内容:

                 "modules": {
                    "isActive": 1,
                    "metadata": {
                        "actionCodes": "",
                        "memos": ""
                    },
                    "moduleCode": "OM",
                    "moduleId": 250,
                    "moduleName": "Org Management",
                    "success": false,
                    "viewId": 0
                },

I need to get the data as sent by the store to server. Thanks Nohsib

Simply change the name in the mapping to the following

只需将映射中的名称更改为以下内容即可

{
   name : 'collection',
   mapping : 'modules.collection',
   defaultValue: []
}

The name config is the name that is used within the model. If you look at the data property of a model object, the name used in the mapping is used to store the value in the model. The name is same name that we use while retrieving data from a model object too. Ex. model.get(name);

名称config是模型中使用的名称。如果查看模型对象的data属性,则映射中使用的名称用于存储模型中的值。名称与我们从模型对象检索数据时使用的名称相同。防爆。 model.get(名称);

From the api.

来自api。

The name by which the field is referenced within the Model

模型中引用字段的名称
