How to filter the Store? - sencha-touch

Question

Who knows how to filter the Store right?
I tried to do it in listener of leafItemTap of Nested List, but my leaf items not tapping now. Massage in console: "Uncaught TypeError: Cannot call method 'filter' of undefined "
Here is Nested list, where Store must be filtered:
Ext.define('Application.view.SplitView', {
extend: 'Ext.Container',
xtype: 'splitview',
config: {
layout: 'card',
store: null
},
initialize: function() {
this.nestedList = Ext.create('Ext.NestedList', {
title : 'Рецепты',
detailCard: Ext.create('Application.view.MainDetail'),
store: this.getStore(),
listeners: {
scope: this,
leafitemtap: this.onLeafItemTap
}
});
this.setItems([this.nestedList]);
},
updateStore: function(newStore) {
if (this.nestedList) {
this.nestedList.setStore(newStore);
}
},
onLeafItemTap: function(nestedList, list, index, node, record, e) {
var psn = record.get('text');
console.log(psn);
var detailCard = nestedList.getDetailCard();
var store = Ext.getStore('Application.store.DetailStore');
store.filter('title', 'Brownies');
console.log(store);
}
});
This is my Store, which I want to filter:
Ext.define('Application.store.DetailStore', {
extend: 'Ext.data.Store',
config: {
model: 'Application.model.DetailModel',
autoLoad :true,
sorters: 'title',
grouper : function(record) {
return record.get('title')[0];
},
proxy: {
type: 'ajax',
url : '/data/data1.php',
reader: {
type: 'json',
rootProperty:'recipes'}
}
}
});
And Store's model:
Ext.define('Application.model.DetailModel', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'title', type: 'string'},
{name: 'serves', type: 'string'},
{name: 'cooktime', type: 'string'},
{name: 'ingridients', type: 'string'},
{name: 'picture', type: 'string'},
{name: 'kitchen', type: 'string'},
{name: 'category', type: 'string'},
{name: 'instructions', type: 'string'}
]
},
fullName: function() {
var d = this.data,
names = [
d.title
];
return names.join(" ");
}
});
I'm new in Sencha and every advice will be useful

The following error means the object which you're calling the filter function on is undefined
"Uncaught TypeError: Cannot call method 'filter' of undefined "
In your case, the store is undefined.
Try to get it by doing :
var store = Ext.getStore('DetailStore');
Also, you could check what stores are in the StoreManager by doing :
console.log(Ext.data.StoreManager.all);
Hope this helps
