ExtJS 6 - Bind proxy data to form - extjs

I have a proxy store that retrieves information from a webservice, I would like to show that information in a Panel in a way like a Grid, in which I set the "dataIndex" parameter to bind in the retrieved data.
How can I achieve this goal without extra coding, is that possible?
Something like this:
Proxy Store:
Ext.define('MyStore', {
extend: 'Ext.data.Store',
alias: 'store.myStore',
model: 'myModel',
autoload: true,
proxy: {
type: <wsType>,
url: <wsUrl>
},
scope: this
});
Panel:
Ext.define('<myPanel>', {
extend: 'Ext.panel.Panel',
...
store: Ext.create(<myStore>),
...
items: [
{
xtype: 'titlePanel',
cls: 'titlePanel',
html: '<div class="titlePanel"><h1>My Title</h1></div>',
},
{
xtype: 'form',
layout: 'vbox',
cls: 'whitePanel',
items: [
{
xtype: 'panel',
layout: 'column',
items: [
{
xtype: 'displayfield',
displayField: 'name',
dataIndex: 'name',
fieldLabel: Ext.locale.start,
name: 'start'
},
...

You don't need Store for displaying a single Record. Proxy can be defined at a model level.
Ext.define('MyApp.model.Contact', {
extend: 'Ext.data.Model',
fields: ['id', 'firstName', 'middleName', 'lastName'],
proxy: {
type: 'ajax',
url: 'contacts.json',
reader: {
type: 'json',
rootProperty: 'data'
}
}
});
Load the model either in view constructor/initComponent or controller init method, once loaded push the record to ViewModel.
initComponent: function() {
this.callParent(arguments);
var me = this;
MyApp.model.Contact.load(1, {
success: function(record, operation) {
me.getViewModel().set('contact', record);
}
})
},
Bind the model property to the display field
items: [{
name: 'firstName',
fieldLabel: 'First Name',
bind: '{contact.firstName}',
xtype: 'displayfield'
}]

ExtJS Grid Not Displaying Rest Data

I have created a mini EXTJS app, defined a model, store, and grid. I have verified the store is working because I can use Chrome debug tools to create an instance and view the data. However, when I attempt to display the data in a grid it never shows.
Here is the code for the app.js:
Ext.application({
launch: function () {
Ext.define('Companies', {
extend: 'Ext.data.Model',
fields: ['id', 'link', 'name']
});
Ext.define('CompaniesStore', {
extend: 'Ext.data.Store',
model: 'Companies',
storeId: 'cStore',
autoLoad: true,
proxy: {
type: 'rest',
url: 'http://corky52547.somee.com/Service1.svc/Companies'
}
});
Ext.create('Ext.container.Viewport', {
name : "viewPort2",
layout: 'fit',
renderTo: Ext.getBody(),
items: [
{
title: 'Bill Reminder Web'
},
{
xtype: 'grid',
title: 'Bills',
height: 100,
width: 100,
columns: [
{text: 'ID', width: 100, dataIndex: 'id'},
{text: 'Link', flex: 1, dataIndex: 'link'},
{text: 'Name', width: 200, dataIndex: 'name'}
],
store: Ext.create('CompaniesStore',{})
}
]
});
}
});
Update:
I am now able to get the data to display but like this with no theme. How do I update the theme?
CORS (Cross Origin requests) is blocking the request to domain.
Layout Fit is also causing some issues.
To get CORS working, you will need to add
Access-Control-Allow-Origin: *
Otherwise, you can use middle-ware proxy like cors-anywhere
Minor mistakes like field names should be matched with exact case they are available in response.
Here is a working POC Code:
Ext.application({
name: "Application",
launch: function () {
Ext.define('Companies', {
extend: 'Ext.data.Model',
fields: ['ID', 'Link', 'Name']
});
Ext.define('CompaniesStore', {
extend: 'Ext.data.Store',
model: 'Companies',
storeId: 'cStore',
autoLoad: true,
proxy: {
type: 'rest',
url: 'https://cors-anywhere.herokuapp.com/http://corky52547.somee.com/Service1.svc/Companies'
}
});
Ext.create('Ext.container.Viewport', {
name: "viewPort2",
renderTo: Ext.getBody(),
items: [{
title: 'Bill Reminder Web'
}, {
xtype: 'grid',
title: 'Bills',
flex: 1,
columns: [{
text: 'ID',
width: 100,
dataIndex: 'ID'
}, {
text: 'Link',
flex: 1,
dataIndex: 'Link'
}, {
text: 'Name',
width: 200,
dataIndex: 'Name'
}],
store: Ext.create('CompaniesStore', {})
}]
});
}
});

Extjs textfield binding

I am trying to find the best way to bind items to a textfield in my extjs project. I downloaded the data into a store with one record in the controller. How would I bind to this textfield from the one record? I would preferably bind in the view, not in the controller
You should read this guide to understand better what binding is
The best solution for you is bind the record on the viewmodel of the view, so:
textfield.setBind({
value:'{myRec.valueToRefer}'
})
viewmodel.set('myRec',record.getData());
If you want, you can also use a form to handle this, using form.loadRecord and giving to the textfield a name..
A tip:
set inside the viewmodel a value to null:
data:{
myRec:null
}
Set your record in the viewmodel after setting the bind to the textfield.
Other tip:
If you can, avoid using setBind and prefer to set the binding directly on textfield creation:
//WILL WORK BUT YOU CAN AVOID IT
textfield.setBind({
value:'{myRec.valueToBind}'
})
//YES
var textfield=Ext.create({
xtype:'textfield',
bind:{
value:'{myRec.valueToBind}'
}
});
Refer to Sencha documentation also
You can use bind config to bind the data or any other config for ExtJS component.
Bind setting this config option adds or removes data bindings for other configs.
For example, to bind the title config:
var panel = Ext.create({
xtype: 'panel',
bind: {
title: 'Hello {user.name}'
}
});
To dynamically add bindings:
panel.setBind({
title: 'Greetings {user.name}!'
});
To remove bindings:
panel.setBind({
title: null
});
In this FIDDLE, I have created a demo for biding. I hope this will help/guide you to achieve you requirement.

Sencha Touch, one store to be used by a list and a dataview display?

So I implemented a dataview and a list format card to display my json in store. I am trying to get the two view to share one store, since the data are the same. However the way i am doing it is not really working, if I only have Dataview or List it works fine. When I have both call the store, it will stop working... please help!
Dataview:
Ext.define('Sencha.view.hoardboard.HoardList', {
extend: 'Ext.DataView',
xtype: "hoardlist",
requires: ['Ext.XTemplate'],
config: {
flex:1,
scrollable: true,
store: 'Plist',
baseCls: 'columns',
itemTpl: '<div class=pin><img src={image}><div style="padding-top: 10px; padding-left: 20px; padding-right:20px">{name}<br>{brand}</div></div>'
}
});
List view
Ext.define('Sencha.view.hoardboard.HoardList2', {
extend: 'Ext.List',
xtype: "hoardlist2",
config: {
flex:1,
scrollable: true,
store: 'Plist',
grouped: true,
itemTpl: '{name}'
}
});
Model
Ext.define('Sencha.model.HoardList', {
extend: 'Ext.data.Model',
config: {
fields: [
{
name: 'name',
type: 'string'
},
{
name: 'image',
type: 'string'
},
{
name: 'type',
type: 'string'
},
{
name: 'brand',
type: 'string'
}
,
{
name: 'color',
type: 'string'
},
{
name: 'description',
type: 'string'
}
]
}
});
Store
Ext.define('Sencha.store.HoardList',{
extend: 'Ext.data.Store',
storeId: 'Plist',
model:'Sencha.model.HoardList',
title: 'My Collection',
autoLoad: true,
sorters: 'name',
grouper: {
groupFn: function(record) {
return record.get('name')[0];
}
},
proxy: {
type: 'ajax',
url : 'products.json',
reader: {type: 'json', rootProperty:'products'}
}
});
Thank you so much!
Generally speaking when you're using Sencha framework you don't share one store object between several visual controls.
If you want to use same store in two places you need to clone it and have two separate store objects.

Load data to form in mvc

In my appliacation , I have a list and detail(form).I want to load data to Detail view(set data to textfields of form) when list item is clicked. For both list and detail, I am getting data from remote server. I am following MVC.
Now, When listItem is clicked, I am able to get data from server and save it to store and also showing detail view. But I am not able to bind data from store to textfields in form.
Model
Ext.define('App.model.Details', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'Name', type: 'string'},
{name: 'BillingStreet', type: 'string'},
{name: 'BillingCity', type: 'string'}
]
}
});
Store
Ext.define('App.store.Details', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.Details',
autoLoad :true,
grouper : function(record) {
return record.get('Name')[0];
},
}
});
list view
Ext.define('App.view.View', {
extend: 'Ext.List',
alias:'widget.contactlist',
fullscreen: true,
id: 'contactlist',
config:{
disableSelection:true,
store:'Contacts',
itemTpl:'{Name}',
items:[
{
xtype:'toolbar',
docked:'top',
title:'Leeds List'
}
]
}
});
Detail view
Ext.define("App.view.ListDetail", {
extend: "Ext.form.Panel",
requires: "Ext.form.FieldSet",
alias: "widget.listDetail",
config:{
scrollable:'vertical'
},
initialize: function () {
this.callParent(arguments);
var topToolbar = {
xtype: "toolbar",
docked: "top",
title: "Details"
};
this.add([
topToolbar,
{ xtype: "fieldset",
items: [{

Please help to bind data to detail view.
So I'm guessing your Contacts Store is defined somewhere else but since this one is working you didn't paste the code here.
So one quick note on the model, where you should always define an idProperty. This is what Sencha use internally to define the "primary key" on your store and therefore work properly when you reload/refresh your store.
Ext.define('App.model.Details', {
extend: 'Ext.data.Model',
config: {
idProperty: 'Name', // Or something from your server maybe?
fields: [
{name: 'Name', type: 'string'},
{name: 'BillingStreet', type: 'string'},
{name: 'BillingCity', type: 'string'}
]
}
});
Secondly, why did you use the initialize method in your ListDetail view when you used the config method in your listView? if you specify the config instead, you will be able to to reuse some of this component in a more easy way somewhere else by doing something like
items: [
{
xtype: 'ListDetail',
anyOtherAttribute: value
}
]
But that's kinda out of scope here. But anyway. So what is wrong here I think is that you have defined a Store for each field of your panel. I'm sorry i can't test my hypothesis, but here is what I would do:
Ext.define("App.view.ListDetail", {
extend: "Ext.form.Panel",
requires: "Ext.form.FieldSet",
alias: "widget.listDetail",
config:{
scrollable:'vertical'
items:[
{
xtype: "toolbar",
docked: "top",
title: "Details"
},
{
xtype: "fieldset",
itemId: 'detailedListFiledset', //Overall, prefer itemId
items: [
{
xtype: 'textfield',
value : 'Name',
label: 'Name' // may be you want placeholders here?
},
{
xtype: 'emailfield',
value : 'BillingStreet',
label: 'Email' // and here..
},
{
xtype: 'passwordfield',
value : 'BillingCity',
label: 'Password' // and here..
}
]
}
]
}
});
Alright, and now the issue seems to be in your controller:
Add a ref to your fieldset
Add a reference to your store
create a afterload callback when your store is loaded (Details)
Either clear the store every time or append data and apply to filter to get the correct record (this is why the idProperty is very useful)
set the record of the fieldset and not the panel
I haven't had the chance to try that, but I'll do it later tonight. But git it a go though.
-- EDIT --
Ok I've finally been abe to code something for you.
A few issues were in your code. I don't really know why you need two stores, but let's say you do. I'm going to give you all the files I used (the two stores, the two models, the three views and the controller). Three main thing were wrong in your code:
you should not load the second store and try to get the record right after. use and 'load' or 'refresh' event for that
SetValues for a form is the correct function to use
You were missing the name property in your form so that the form know to which value of the store/model to bind to the field.
ContactModel:
Ext.define('App.model.Contact', {
extend: 'Ext.data.Model',
config: {
idProperty: 'id',
fields: [
{name: 'id', type: 'int'},
{name: 'name', type: 'string'}
]
}
});
ContactStore:
Ext.define('App.store.ContactStore', {
extend: 'Ext.data.Store',
requires:['App.model.Contact'],
config: {
storeId: 'ContactStore',
model: 'App.model.Contact',
autoLoad :true,
data: [
{id: 0, name: 'Foo'},
{id: 1, name: 'Bar'}
]
}
});
DetailModel:
Ext.define('App.model.Detail', {
extend: 'Ext.data.Model',
config: {
idProperty: 'id',
fields: [
{name: 'id', type: 'int'},
{name: 'name', type: 'string'},
{name: 'billingStreet', type: 'string'},
{name: 'billingCity', type: 'string'}
]
}
});
DetailStore:
Ext.define('App.store.DetailStore', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.Detail',
autoLoad :true,
data: [
{id: 0, name: 'Foo', billingStreet:'here', billingCity: 'Somewhere'},
{id: 1, name: 'Bar', billingStreet:'there', billingCity: 'Somewhere else'}
]
}
});
ContactView:
Ext.define('App.view.ContactList', {
extend: 'Ext.List',
xtype: 'contactList',
fullscreen: true,
config: {
itemId: 'contactList',
store:'ContactStore',
emptyText: 'test',
itemTpl: new Ext.XTemplate(
'{name}'
),
items:[
{
xtype:'toolbar',
docked:'top',
title:'Leeds List'
}
]
}
});
DetailView:
Ext.define('App.view.Detail', {
extend: 'Ext.form.Panel',
requires: ['Ext.form.FieldSet'],
xtype: "detail",
config:{
scrollable:'vertical',
items: [
{
xtype: 'toolbar',
docked: 'top',
title: 'Details'
},
{
xtype: 'fieldset',
itemId: 'detailForm',
items: [{
xtype: 'textfield',
store: 'Details',
name: 'name',
placeHolder : 'Name',
label: 'Name'
},
{
xtype: 'textfield',
store: 'Details',
placeHolder : 'BillingStreet',
name: 'billingStreet',
label: 'BillingStreet'
},
{
xtype: 'textfield',
store: 'Details',
placeHolder : 'BillingCity',
name: 'billingCity',
label: 'BillingCity'
}
]
}
]
}
});
Main view:
Ext.define('App.view.Main', {
extend: 'Ext.Container',
xtype: 'main',
config: {
layout: 'hbox',
items: [
{
xtype: 'contactList',
flex:1
},
{
xtype: 'detail',
flex:2.5
}
]
}
});
Main Controller:
Ext.define('App.controller.Main', {
extend : 'Ext.app.Controller',
requires: [
'Ext.Toolbar',
'Ext.List',
'App.store.ContactStore',
'App.store.DetailStore',
'App.view.Detail',
'App.view.ContactList'
],
config: {
//#private
detailStore: null,
currentListIndex: -1,
views : [
'App.view.ContactList',
'App.view.Detail'
],
refs: {
list: 'contactList',
detail: 'detail',
detailForm: 'detail #detailForm'
},
control: {
list: {
itemtap: 'handleItemTapList'
}
}
},
launch: function() {
var store = Ext.getStore('DetailStore');
store.on('refresh', 'handleDetailStoreLoad', this);
this.setDetailStore(store);
},
handleItemTapList: function(list, index, target, record) {
this.setCurrentListIndex(index);
this.getDetailStore().load();
},
handleDetailStoreLoad: function (store) {
debugger;
var record = store.getAt(this.getCurrentListIndex());
this.getDetail().setValues(record.data);
}
});
We could argue on a few things but I tried to go straight to the point and make it work. If you have more questions please ask but this example is working for me. In my opinion, you might not need the second store, as the contact detail could be nested in the COntact store, and you could use the hasMany property of the store.
use form.setRecord() to load a record into a form
make sure your form elements have name property values that match the model name properties
as you have a store, you will have to get a reference to ONE model to load, using say getAt() or find() methods to get or find a model in your store

extjs combo box not binding to array store

Using the example in "ext-designer-for-ext-js-4-users-guide.pdf" i've put together the following. The issue is that the store is not binding. ie the select is empty.
MyComboBox.js
Ext.define('MyApp.view.MyComboBox', {
extend: 'MyApp.view.ui.MyComboBox',
initComponent: function() {
var me = this;
me.callParent(arguments);
}
});
Ext.define('MyApp.view.ui.MyComboBox', {
extend: 'Ext.form.field.ComboBox',
fieldLabel: 'comboList',
displayField: 'comboList',
queryMode: 'local',
store: 'MyArrayStore',
triggerAction: 'all',
valueField: 'comboList',
initComponent: function() {
var me = this;
me.callParent(arguments);
}
});
store/MyArrayStore.js
Ext.define('MyApp.store.MyArrayStore', {
extend: 'Ext.data.Store',
constructor: function(cfg) {
var me = this;
cfg = cfg || {};
me.callParent([Ext.apply({
autoLoad: true,
storeId: 'MyArrayStore',
data: [
[
'Search Engine'
],
[
'Online Ad'
],
[
'Facebook'
]
],
proxy: {
type: 'ajax',
reader: {
type: 'array'
}
},
fields: [
{
name: 'comboList'
}
]
}, cfg)]);
}
});
** update **
this was driving me crazy. It's [turns out][1] my array need to be json format. When i updated it to
[{"comboList" : "Hello"}, {"comboList" : "Hi"}, {"comboList" : "GoodMorning"}]
it worked.
I started to try and pick apart your implementation but it seems somewhat convoluted, starting with the store where there is local data and a proxy defined but no url for the proxy.
It seemed easier to just give you a simplified implementation of a combobox (using local data because it seems that is what you are trying to do):
// the datastore
var myStore = Ext.create('Ext.data.Store', {
fields: ['value', 'name'],
data: [
{value: 1, name: 'Search Engine'},
{value: 2, name: 'Online Ad'},
{value: 3, name: 'Facebook'}
]
});
// a window to hold the combobox inside of a form
myWindow = Ext.create('Ext.Window', {
title: 'A Simple Window',
width: 300,
constrain: true,
modal: true,
layout: 'fit',
items: [{
// the form to hold the combobox
xtype: 'form',
border: false,
fieldDefaults: {
labelWidth: 75
},
bodyPadding: '15 10 10 10',
items: [{
// the combobox
xtype: 'combo',
id: 'myCombo',
fieldLabel: 'Title',
valueField: 'value',
displayField: 'name',
store: myStore,
queryMode: 'local',
typeAhead: true,
forceSelection: true,
allowBlank: false,
anchor: '100%'
},{
// shows the selected value when pressed
xtype: 'button',
margin: '10 0 0 100',
text: 'OK',
handler: function() {
alert('Name: ' + Ext.getCmp('myCombo').getRawValue() +
'\nValue: ' + Ext.getCmp('myCombo').value);
}
}]
}]
});
// show the window
myWindow.show();
This creates a combobox inside of a little window with an OK button. When you press OK it will alert the visible text of the combobox Ext.getCmp('myCombo').getRawValue() and the value of the item in the combobox Ext.getCmp('myCombo').value.
If you drop this in your project you can get an idea of how it implements, it should just run.
If you actually wanted a remote datastore (from a webservice that returns json for example) you would just need to change the datastore configuration like so:
var myRemoteStore = Ext.create('Ext.data.Store', {
fields: ['value', 'name'],
proxy: {
type: 'ajax',
url: 'myWebservice.php', // whatever your webservice path is
reader: 'json',
},
autoLoad:true
});
