What is the proper way to filtering ViewModel stores and implement to ExtJS Panel?

Through ViewModel stores I'm getting this JSON data;
{
"success": true,
"msg": "OK",
"count": 2,
"data": [
{
"firstname": "BLA",
"lastname": "BLALA",
"isactive": true,
...
},
{
"firstname": "BLAAA",
"lastname": "BLALAAA",
"isactive": false,
...
}
I have two grids on one panel and one of them will load data only with isactive: true field, other grid will load only with false. So where and how I need to filtering store to load specified data to grids?
Here is VM;
Ext.define('MyApp.view.ListingVM', {
extend: 'Ext.app.ViewModel',
alias: 'viewmodel.listing',
requires: [...],
reference: 'loyaltyvm',
stores: {
// Should I define the filter on here?
bonusTrans: {
storeId: 'bonusTrans',
// reference: 'bonusTrans',
model: 'MyApp.model.BonusTrans',
autoLoad: true,
session: true,
pageSize: MyApp.Globals.LIST_PAGE_SIZE
}
}
});
This is panel's grid sample where defined both of Grids. I've tried several way to get store and filtering but couldn't be succes;
getColumns: function () {
var me = this;
var panelItems = [
{
xtype: 'container',
layout: {type: 'hbox', align: 'stretch', pack: 'start'},
items: [
xtype: 'bonustrans',
flex: 1,
title: 'Current Bonus',
getListCols: function () {
var me = this;
debugger;
// var activeStore = Ext.getStore('bonusTrans');
// var activeStore = me.viewModel.get('bonusTrans');
// var view = me.getView();
// var vm = view.getViewModel();
// var vm.getStore('bonusTrans')
// var activeStore = me.getViewModel().getStore('bonusTrans');
var activeStore = me.getViewModel('loyaltyvm').getStores('bonusTrans');
activeStore.filter('isactive', 'true');
var listCols = [
{
xtype: 'firstnamecol',
flex: 1
},
{
xtype: 'checkoutcol'
},
{
xtype: 'bonustotalcol'
}
];
return listCols;
}
//... other Grid is just defined below of this line and it should loads data only with 'isactive' field is false.

Use chained stores, fiddle:
Ext.application({
name : 'Fiddle',
launch : function() {
new Ext.container.Viewport({
layout: {
type: 'hbox',
align: 'stretch'
},
viewModel: {
stores: {
everything: {
autoLoad: true,
proxy: {
type: 'ajax',
url: 'data1.json'
}
},
active: {
type: 'chained',
source: '{everything}',
filters: [{
property: 'active',
value: true
}]
},
inactive: {
type: 'chained',
source: '{everything}',
filters: [{
property: 'active',
value: false
}]
}
}
},
items: [{
flex: 1,
xtype: 'gridpanel',
title: 'Active',
bind: '{active}',
columns: [{
dataIndex: 'name'
}]
}, {
flex: 1,
xtype: 'gridpanel',
title: 'Inactive',
bind: '{inactive}',
columns: [{
dataIndex: 'name'
}]
}]
});
}
});

The way of chained stores is surely the best,
here you can see a working fiddle on classic
and here is the code:
Ext.application({
name: 'Fiddle',
launch: function () {
var storeAll = Ext.create('Ext.data.Store', {
storeId: 'storeAll',
fields: [{
name: 'firstname'
}, {
name: 'lastname'
}, {
name: 'active'
}],
data: [{
firstname: 'test1',
lastname: 'test1',
active: true
}, {
firstname: 'test2',
lastname: 'test2',
active: true
}, {
firstname: 'test3',
lastname: 'test3',
active: false
}]
}),
chainedStoreActive = Ext.create('Ext.data.ChainedStore', {
source: storeAll,
filters: [{
property: 'active',
value: true
}]
}),
chainedStoreNoActive = Ext.create('Ext.data.ChainedStore', {
source: storeAll,
filters: [{
property: 'active',
value: false
}]
});
Ext.create({
xtype: 'viewport',
layout: {
type: 'vbox',
align: 'stretch'
},
items: [{
xtype: 'gridpanel',
title: 'grid ALL',
store: storeAll,
columns: [{
text: 'First Name',
dataIndex: 'firstname'
}, {
text: 'Last Name',
dataIndex: 'lastname'
}],
flex: 1
}, {
xtype: 'gridpanel',
title: 'grid active',
store: chainedStoreActive,
columns: [{
text: 'First Name',
dataIndex: 'firstname'
}, {
text: 'Last Name',
dataIndex: 'lastname'
}],
flex: 1
}, {
xtype: 'gridpanel',
title: 'grid inactive',
store: chainedStoreNoActive,
columns: [{
text: 'First Name',
dataIndex: 'firstname'
}, {
text: 'Last Name',
dataIndex: 'lastname'
}],
flex: 1
}],
renderTo: Ext.getBody()
});
}
});
The global or the "allelements" store, need to be a global store, the chained ones can be created in a viewmodel of a view.

ExtJS 4.2 - How to map array to a model field and display dynamically on a grid column?

I have this json data:
{
id: 1,
name: 'something',
description: 'somethingsomething',
customers: [{
id: 1,
username: 'cust1'
}, {
id: 2,
username: 'cust2'
}]
}
While I have no problems displaying the first three fields on the gridpanel, I however have an issue retrieving the array object for the customers field. My model goes like this:
fields: [
'id', {
name: 'name',
sortType: Ext.data.SortTypes.asUCString
},
'permanent', {
name: 'description',
Type: Ext.data.SortTypes.asUCString
}, {
name: 'customers',
Type: Ext.data.SortTypes.asUCString
}, {
name: 'username',
Type: Ext.data.SortTypes.asUCString,
mapping: 'customers[0].username'
}
]
When I try to access customers[0].username, it only retrieves the ones on that specified index. Removing the index number returns undefined as I assume it is looking for what index to return from. How do I properly retrieve all of customers: [] and display it to my grid where it is structured as:
{
xtype: 'gridpanel',
store: oStore,
viewConfig: {
loadMask: false,
enableTextSelection: true
},
hideHeaders: false,
bodyBorder: true,
columns: [{
text: 'Customer',
dataIndex: 'username',
flex: 1
}, {
header: '',
xtype: 'actioncolumn',
itemId: 'remove-player-btn',
width: 50,
sortable: false,
resizable: false,
menuDisabled: true,
items: [{
icon: 'resources/img/x.png',
tooltip: 'Remove Player',
scope: oMe
}],
editor: {
xtype: 'text',
name: 'deleteRow'
}
}]
}

You can use convert function available in model.This convert function is used for some calculation purpose & map response data for our needs.For example I will map username as below:
fields: [
{
name:'username',
convert:function(value,model)
{
return model.data.customers.username;
}
}
]
Use same technique for id field.Reply if any issues.

Association between models failing in Ext js 6

I am working on small example to understand association which is working fine in Ext js 5 but failing in Ext js 6 version.
Ext.onReady(function() {
// parent model
Ext.define('Continent', {
extend: 'Ext.data.Model',
field: ['name'],
hasMany: {
model: 'Country',
name: 'countries'
}
});
//child model
Ext.define('Country', {
extend: 'Ext.data.Model',
field: ['name'],
associations: [{
type: 'belongsTo',
model: 'Continent',
associationKey: 'countries',
}]
});
//created store for parent which contains child data
Ext.define('ContinentStore', {
extend: 'Ext.data.Store',
storeId: 'continent',
model: 'Continent',
autoLoad: true,
proxy: {
type: 'memory',
data: [{
name: 'Asia',
countries: [{
name: 'India'
}, {
name: 'Srilanka'
}, {
name: 'Bangladesh'
}]
}, {
name: 'Africa',
countries: [{
name: 'Nigeria'
}, {
name: 'Kenya'
}, {
name: 'South Africa'
}]
}, {
name: 'America',
countries: [{
name: 'West'
}, {
name: 'East'
}, {
name: 'South'
}]
}]
}
});
var continentGrid = Ext.create('Ext.grid.Panel', {
title: 'Continent Grid',
store: Ext.create('ContinentStore'),
width: '50%',
height: '100%',
listeners: {
select: function(cmp, record, index) {
//record.countries() will return new store.
// to append new store I have used reconfigure method.
Ext.getCmp('CountryGrid').reconfigure(record.countries());;
}
},
columns: [{
dataIndex: 'name',
text: 'Continent',
flex: 1
}]
});
var countryGrid = Ext.create('Ext.grid.Panel', {
title: 'Country Grid',
id: 'CountryGrid',
width: '50%',
height: '100%',
columns: [{
dataIndex: 'name',
text: 'Country',
flex: 1
}]
});
Ext.create('Ext.window.Window', {
width: 500,
height: 400,
layout: 'hbox',
autoShow: true,
items: [continentGrid, countryGrid]
})
//console.log(continent);
});
when I try to run the example in Ext js 6 verison getting below error.
Uncaught Error: hasMany ("Continent") and belongsTo ("Country") should not be used in conjunction to declare a relatextionship. Use only one.(…)

Ext js paging with local data does not work

I try to enable paging with ExtJs4 grid. Paging toolbar looks like it is working but paging is not enabled in grid.Can you help me about what I am missing?
Ext.onReady(function () {
var i = 1;
Ext.define('User', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', type: 'int' },
{ name: 'firstName', type: 'string' },
{ name: 'lastName', type: 'string' },
{ name: 'age', type: 'int' },
{ name: 'eyeColor', type: 'string' }
]
});
It looks that the problem is with totalCount but, there is something more.
var store= Ext.create('Ext.data.Store', {
model: 'User',
totalCount:50,
pageSize: 10,
autoLoad: { start: 0, limit: 10 },
proxy: {
type: 'memory',
reader: {
root: 'users',
totalProperty: 'totalCount'
}
},
data: [
{ id: i++, firstName: 'Ed', lastName: 'Spencer', age:20, eyeColor: 'blue' },
{ id: i++, firstName: 'Tommy', lastName: 'Maintz', age: 30, eyeColor: 'black' },
{ id: i++, firstName: 'Aaron', lastName: 'Conran', age: 40, eyeColor: 'blue' },
{ id: i++, firstName: 'Jamie', lastName: 'Avins', age: 50, eyeColor: 'black' },
{ id: i++, firstName: 'Ed', lastName: 'Spencer', age: 20, eyeColor: 'blue' }
.
.
.
]
});
Paging toolbar looks like it is working but grid values does not change according to the page numbers.
Ext.create('Ext.grid.Panel', {
title: 'Users',
store: store,
proxy: {
type: 'memory',
enablePaging: true
},
columns: [
{ header: 'ID', dataIndex: 'id', width:50 },
{ header: 'Name', dataIndex: 'firstName' },
{ header: 'Last Name', dataIndex: 'lastName' },
{ header: 'Age', dataIndex: 'age', width: 50 },
{ header: 'Eye Color', dataIndex: 'eyeColor' }
],
height: 600,
width: 800,
dockedItems: [{
xtype: 'pagingtoolbar',
store: store,
pageSize: 10,
dock: 'bottom',
displayInfo: true
}],
renderTo: Ext.getBody()
});
});

You need proxy: 'pagingmemory' which is Ext.ux.data.PagingMemoryProxy.
From doc:
Paging with Local Data
Paging can also be accomplished with local data using extensions:
Ext.ux.data.PagingStore
Paging Memory Proxy (examples/ux/PagingMemoryProxy.js)
Also note that there is no need to have:
totalCount in the store config (it will be provided by the proxy);
proxy on the grid (it's already within the store);
pageSize in the paging toolbar config (will be taken from the store).

ExtJS 4.2.3 Grouping Bug

I am using the store.group() to provide option to the user to group the grid by various fields.
Using extjs4.2.3 now after having faced many bugs in 4.2.1, store.group() does not seem to be working at all.
How to replicate:
Press the "Group" button, which should group the grid. Only sorts the data.
Choose "Group by this field" from the column menu and the grouping starts to work fine.
Similarly store.clearGrouping() behaves the same way.
Here is sample code:
Ext.define('TestResult', {
extend: 'Ext.data.Model',
fields: ['student', 'subject', {
name: 'mark',
type: 'int'
}]
});
Ext.create('Ext.grid.Panel', {
width: 200,
height: 240,
itemId: 'gridtest',
renderTo: document.body,
features: [{
groupHeaderTpl: 'Subject: {name}',
ftype: 'groupingsummary'
}],
store: {
model: 'TestResult',
itemId: 'testStore',
//groupField: 'subject',
data: [{
student: 'Student 1',
subject: 'Math',
mark: 84
}, {
student: 'Student 1',
subject: 'Science',
mark: 72
}, {
student: 'Student 2',
subject: 'Math',
mark: 96
}, {
student: 'Student 2',
subject: 'Science',
mark: 68
}]
},
columns: [{
dataIndex: 'student',
text: 'Name',
summaryType: 'count',
summaryRenderer: function(value) {
return Ext.String.format('{0} student{1}', value, value !== 1 ? 's' : '');
}
}, {
dataIndex: 'mark',
text: 'Mark',
summaryType: 'average'
}],
tbar: [{
xtype: 'button',
text: 'Group',
handler: function(button, e) {
var store = Ext.ComponentQuery.query('#gridtest')[0].getStore();
store.group('subject');
}
}, {
xtype: 'button',
text: 'clear',
handler: function(button, e) {
var store = Ext.ComponentQuery.query('#gridtest')[0].getStore();
store.clearGrouping();
}
}]
});
Running the code in ExtJS 4.2.1 works fine on the sencha fiddle, but not on 4.2.3
I tested using the code preview option on http://docs.sencha.com/extjs/4.2.3/.

Above code is working fine in extjs-4.2.3.
Open http://docs.sencha.com/extjs/4.2.3/ and in Developer tools Console tab execute following code:-
Group on 'Group' button is working fine.
Ext.define('TestResult', {
extend: 'Ext.data.Model',
fields: ['student', 'subject', {
name: 'mark',
type: 'int'
}]
});
var grpGrid = Ext.create('Ext.grid.Panel', {
width: 200,
height: 240,
itemId: 'gridtest',
renderTo: document.body,
features: [{
groupHeaderTpl: 'Subject: {name}',
ftype: 'groupingsummary'
}],
store: {
model: 'TestResult',
itemId: 'testStore',
//groupField: 'subject',
data: [{
student: 'Student 1',
subject: 'Math',
mark: 84
}, {
student: 'Student 1',
subject: 'Science',
mark: 72
}, {
student: 'Student 2',
subject: 'Math',
mark: 96
}, {
student: 'Student 2',
subject: 'Science',
mark: 68
}]
},
columns: [{
dataIndex: 'student',
text: 'Name',
summaryType: 'count',
summaryRenderer: function(value) {
return Ext.String.format('{0} student{1}', value, value !== 1 ? 's' : '');
}
}, {
dataIndex: 'mark',
text: 'Mark',
summaryType: 'average'
}],
tbar: [{
xtype: 'button',
text: 'Group',
handler: function(button, e) {
var store = Ext.ComponentQuery.query('#gridtest')[0].getStore();
store.group('subject');
}
}, {
xtype: 'button',
text: 'clear',
handler: function(button, e) {
var store = Ext.ComponentQuery.query('#gridtest')[0].getStore();
store.clearGrouping();
}
}]
});
Ext.create('Ext.window.Window', {
title: 'Hello',
height: 200,
width: 400,
layout: 'fit',
items: [grpGrid]
}).show();

Issue is resolved in nightly build for ExtJS 4.2.4
