Hi,

I have a data like following
Code:
{
    "name": "ABC",
    "type": "automobile",
    "items": {
        "uri": "items",
        "collection": [
            {
                "category": {
                    "name": "First Category",
                    "automobile": "50cc"
                }
            }
        ]
    }
}
I have a parent model:



Code:
Ext.define('App.model.Product',
{
    extend: 'Ext.data.Model',
    requires: [
        'App.model.Category',
        
    ],
    idProperty: 'name',
    fields: [
        'name',
        'type'
    ],
    hasMany: [
        {
            model: 'App.model.Category',
            name: 'objects',
            associationKey: 'items.collection'
        }
    ],
    proxy: {
        type: "rest",
        format: "json",
        url: 'myurl'
    },
    autoSync: true,
    
});
Child model:




Code:
Ext.define('App.model.Category', {
    extend: 'Ext.data.Model',
    belongsTo: [
        {
            name: 'products',
            instanceName: 'products',
            getterName: 'getProducts()',
            setterName: 'set',
            model: 'App.model.Product',
            primaryKey:'name'
        }
    ],
    fields: [
        {
            name: 'name',
            mapping: 'category.name'
        },
        {
            name: 'listtype',
            mapping: 'category',
            convert: function(object, model) {
              //here object returns as{  "name": "First Category", "automobile": "50cc" }
//I want to some how get the parent's models type parameter which is automobile and get it here as
  // var type=model.getCategory().get('type')- but this is always null.
var listtype=object[type];


                return listtype;
            }
        }
    ],




});
Basically, i want to get the type from parent model (say automobile in this case) and map if child model has that field and return as listtype.

How can I get parent model's type value from child model?
Pls help
