VERY SIMPLE Tree store

Hi guys,

I have looked around but I still don't understand how to create treestore properly.

I have this very simple json that I get from a server:

Code:

{
  "Results": [
    {
      "name": "John",
      "age": 23,
      "cars": [
        {
          "name": "Clio",
          "brand": "Renault"
        },
        {
          "name": "Class S",
          "brand": "Mercedes"
        }
      ]
    },
    {
      "name": "Michel",
      "age": 42,
      "cars": [
        {
          "name": "Qashqai",
          "brand": "Nissan"
        }
      ]
    }
  ]
}

I have my two models:

Code:

Ext.define('Person', {
    extend: 'Ext.data.Model',
    fields: [ 'name', 'age']
});


Ext.define('Car', {
    extend: 'Ext.data.Model',
    fields: [ 'name', 'brand']
});

Now I know that I have to create a tree store, but in all example that I have seen, there is always a "children" property in the json, which I don't have.

How to create a tree store with the following json?

Thanks a lot in advance !!
