how to read extjs data store

Question

I want to read a particular value of an extjs data store and manipulate it locally. Response xml looks like : ``` abcdefbook1 ``` My store will have just one user entry when response is received and i want to read 'bname' value. So far i have tried two approaches and both giving error. approach1: ``` Ext.define('user', { extend: 'Ext.data.Model', fields: [ 'name', 'surname'], hasMany: {model: 'Book', name: 'book'}, proxy: { type: 'rest', url : request, reader: { type: 'json', root: 'user'} } }); Ext.define('Book', { extend: 'Ext.data.Model', fields: [ 'name'], belongsTo: 'user' }); var userstore = Ext.create('Ext.data.Store', { model: "user" }); incidentstore.load({ callback: function() { var inc = userstore.first(); var bk = inc.getBook(); console.log(dev.get('bname')); } }); ``` Running above code gives error that 'Ext.define is not a function'. Approach2: ``` var proxy1 = new Jx.JxHttpProxyRest({ url: request,…

Accepted Answer

Below code worked for me :

```
var newproxy = new Ext4.data.proxy.Rest({
    url : request,
    headers : {
        },
    reader :  {
        type : 'json',
        root : 'user.book'
    }});

// Typical Store collecting the Proxy, Reader and Writer together.
 var newstore = Ext4.create('Ext4.data.Store', {
     id : 'book',
     fields: ['bname'],
     restful : true, // <-- This Store is RESTful
     autoLoad : true,
     proxy : newproxy
 });

var book;
newstore.load();
newstore.each(function(rec) {
    book= rec.get('bname');
});
```
