Model: Correct mapping to populate a form textfield from an array of objects?

[koopatroopa]

Context: My JSON contains an array and I have to "flatten" it to put data in the form view.
The line in blue is how I do it:

JSON received from server containing an array

                names: [{
                    name: "first",
                    value: "John"
                },{
                    name: "last",
                    value: "DOE"
                }],

My Form panel

        items: [
            {
                xtype: 'fieldset',
                items: [
                    {
                        xtype: 'textfield',
                        label: 'Field',
                        name: 'first_name'
                    }
                ]
            }

My Model

Ext.define('Test.model.Person', {
    extend: 'Ext.data.Model',


    requires: [
        'Ext.data.Field',
        'Ext.data.association.HasMany'
    ],
    uses: [
        'Test.model.Name'
    ],


    config: {
        fields: [
            {
                mapping: 'names.filter(function(obj){return obj.name == "first"; })[0].value;',
                name: 'first_name',
                type: 'string'
            }
        ],
        hasMany: {
            model: 'Test.model.Name'
        }
    }
});

IT WORKS: the form is displayed with the `John` value in the `first_name` textfield. However my question is: it is the right way to maps arrays to forms? Or is there a better way?

Koopatroopa how are you? can you put an example about how you do an objects array in a form? i need something like this:

"address" : {
"address" : "Avenida Madison",
"city" : "New York, USA"
}

thats a part of a json file, but i dont know how to put this Adress and city value inside the Address array

this is my entire json file:

{
"id": 1,
"name": "Acrecer",
"identification": "963.654.988",
"email": "[email protected]",
"phonePrimary": "111 11 11",
"phoneSecondary": "",
"fax": "",
"mobile": "(333) 555-55-55",
"observations": "",
"type" : ["client"],
"address" : {
"address" : "Avenida Madison",
"city" : "New York, USA"
},
"seller": {
"id" : "52",
"name" : "Diana Giraldo",
"identification" : 560,
"observations" : 320
},
"term" :
{
"id" : 2,
"name" : "8 días",
"days" : 8
},
"priceList" : null,
"internalContacts" : [
{
