How to create more than one JSON store from a get request?

Lets suppose I have this web application built using extjs4 开发者_如何学编程in my client-side and a Zend framework action controller in server-side. I have array of arrays in server-side that they could be output as JSON to the client.when i want to create only one store,usual way is working like this:

    Ext.define('MA.store.AdminResources', {
extend : 'Ext.data.Store',
fields : [ {
    name : 'id'
}, {
    name : 'name'
} ],
autoLoad : true,
proxy : {
    type : 'ajax',
    url : './account/adminresources',
    reader : {
        type : 'json'
        //,root : 'users'
    }
}

});

what if i wanted to create multiple JSON stores from just A single http request to the server? this server will not receive a remote proxy request per store and one request will be done for ALL stores. Here is an example of my JSON which is returned by server:

{
"adminsettings"{"userid":3333,"primaryemail":"1@1.com","firstname":"","middlename":null}
,"countries":{"AD":"Andorra","AE":"UnitedArabEmirates","AF":"Afghanistan"...}
,"languages":{"aa":"Afar","ab":"Abkhazian","ace":"Achinese","ach":"Acoli"...
}}

How can JSON stores for adminsettings,countries,languages be created with just one http request to the server? perhaps i need to define one proxy and 3 readers?!

As you can see in the documentation you can define store without proxy:

Ext.create('Ext.data.Store', {
    model: 'User',
    data : [
        {firstName: 'Ed',    lastName: 'Spencer'},
        {firstName: 'Tommy', lastName: 'Maintz'},
        {firstName: 'Aaron', lastName: 'Conran'},
        {firstName: 'Jamie', lastName: 'Avins'}
    ]
});

then It's easy to make an ajax request and onSuccess to load data manualy:

Something like this:

adminSettings = Ext.create('Ext.data.Store', {model: AdminSettings});
countries = Ext.create('Ext.data.Store', {model: Country});

Ext.ajax.request({
    url: './account/adminresources',
    success: function(response) {
        var json = Ext.decode(response.responseText);
        adminsettings.loadData(json.adminsettings);
        countries.loadData(json.countries);
        //...
    } 
});

While reading on extjs learning center grid faq i found the exact question and answer to my question. Here is the question and the answer:

Load multiple stores with one AJAX request?

There is also an example using XML here

display data to multiple data stores from a single json string that a returned as part of a single http request.

Option 1: (see this thread)

//create a JSON object:
{
dataStore1: /*1st json string */,
dataStore2: /*2nd json string */
}
//decode the json packet...
var json = Ext.decode(response.responseText);
//load the stores:
store1.loadData(json.dataStore1);
store2.loadData(json.dataStore2);

Option 2:

 //create a JSON object:
 {
 dataStore1: /*1st json string */,
 dataStore2: /*2nd json string */
 }
 //decode the json packet...
 var json = Ext.decode(response.responseText);
 //create new proxy data for stores as hendricd mentioned:
 store1.proxy.data = json.dataStore1;
 store2.proxy.data = json.dataStore2;
 //load stores
 store1.load();
 store2.load();

 //where stores' proxy has to be defined like this:
 proxy: new Ext.ux.data.BufferedPagingMemoryProxy([])
 //I guess this can be used in case someone is using PMP (paging memory proxy)
