Ext.define("extcityview.model.ParentModel", {
extend: 'Ext.data.Model',
fields: [
'parentName', 'parentAge'
],
hasMany: {model: 'extcityview.model.ChildrenModel', name: 'children'},
});
Ext.define("extcityview.model.ChildrenModel", {
extend: 'Ext.data.Model',
hasMany : {model:'extcityview.model.ChildModel', name:'child', associationKey: 'childItems'},
belongsTo: 'extcityview.model.ParentModel'
});
Ext.define("extcityview.model.ChildModel", {
extend: 'Ext.data.Model',
fields: [

],
belongsTo: 'extcityview.model.ChildrenModel'
});
ChildStore.js
Code:
Ext.define('extcityview.store.ChildStore', {
extend : 'Ext.data.Store',
storeId : 'samplestore',
model : 'extcityview.model.ParentModel',
autoLoad : 'true',
proxy : {
type : 'ajax',
url : 'sample.json',
reader : {
type : 'json',
root :'parents.parent1.parent'

In app.js alert the value
Code:
store.load({
callback: function()
{
console.log("i am in callback");
var parent = store.first();
alert("parent"+parent);
console.log("parent"+parent);
parent.children().each(function(children){
children.child().each(function(child) {
alert("sub region anme"+child.get('childId'));
console.log("sub region name"+child.get('childId'));
});
});
}
