read json data with model

[jkristen]

Hey guys,

i'm trying to read json data from server with a Ext.regModel component. The examples from Sencha API Documentation are not useful for me. The json response i get, contains a other structure. How can i parse a structur like this.

 {
    "car":{
        "id":"971",
        "distance":null,
        "expires":"2011-02-28 22:59:00",
        "remaining":null,
        "remaining_interval":"20000",
        "isbookmarked":"0",
        "url":"....",
        "customer":{
            "id":"794",
            "icon":"...",
            "title":"..."        },
        "affiliate":{
            "id":"30",
            "icon":"...",
            "title":"..."        },
        "title":"BMW",
        "description":".....",
        "image":"...."
    }

thanks

additional information:
my Problem ist to read/parse the "customer" Object in this Json structure.

[
    {
    "car":{
        "id":"253",
        "distance":"...",
        "expires":"...",
        "customer":{
            "id":"175",
            "title":"...."        
        },
        "affiliate":{
            "id":"1",
            "title":"...."        
        },
        "title":"BMW",
        "image":"....gif"
    }
},{
    "car":{
        "id":"955",
        "distance":"...",
        "expires":"...",
        "customer":{
            "id":"780",
            "title":"...."
        },
        "affiliate":{
            "id":"30",
            "title":"...."        
        },
        "title":"Audi",
        "image":"..."
    }
}]

i use currently a "regModel" to pars the Car Object and that looks fine for me.

	Ext.regModel('CarList', {
			fields: ['title', 'image', 'distance', 'expires', 'id']

but how get i access to the customer and affiliate object?
i tryed to set customer.title in the "reg.Model" and figure out that the "car" object actually contains the customer.title value but i can not access to this via the tpl tag of my "Ext.list".

{(customer.title)}
