I am new to Sencha touch and need your help to resolve the issue. I am trying to display the list of children text using following JSON and Sencha touch code. I looked thorough the API and found that the Child data can be accessed, but then I am not sure how I can send that back to Panel/Store to display the list as
- Child 21
- Child 22
I have nested JSON data as follows:
{
"items":[
{
"id":"1",
"text": "Parent 1",
"leaf": false,
"items": [
{
"id":1,
"text": "child 1",
"leaf": true
},
{
"id":2,
"text": "child 2",
"leaf": true
}
]
},
{
"id":"2",
"text": "Parent 2",
"leaf": false,
"items": [
{
"id":3,
"text": "child 21",
"leaf": true
},
{
"id":4,
"text": "Child 22",
"leaf": true
}
]
}
]
}
Now my sencha touch code is as follows:
Ext.ns('MyApp');
MyApp.Child= Ext.regModel(Child, {
fields: ['id','text','day','date'],
belongsTo: 'Parent',
idProperty:'id',
proxy: {
type: 'rest',
url: 'test.json'
}
});
MyApp.Parent = Ext.regModel('Parent', {
fields: [
{name: 'id', type: 'int'},
{name: 'text', type: 'string'}
] ,
associations: [
{ type: 'hasMany', model: 'Child', name: 'items'}
],
proxy: {
type: 'ajax',
url: 'test.json'
}
});
MyApp.parentStore = new Ext.data.Store({
model : 'Parent',
proxy: {
type: 'rest',
url: 'test.json',
reader: {
type: 'json',
root : 'items'
}
},
autoLoad:true
});
MyApp.parentStore.filter('id','2');
// Do something here to get the list of child items.
// MyApp.childStore = ?
MyApp.appList = new Ext.Panel ({
fullscreen : true,
dockedItems : [
{
xtype : 'toolbar',
title : 'Applications',
dock : 'top'
}
],
items: [{
xtype: 'list',
store: MyApp.childStore, // ??????
itemTpl: '<div class="contact"><strong>{text}</strong></div>'
}]
});
