My JsonStore is so defined:
var data_json = new Ext.data.JsonStore({
url: '/Game/json_index',
autoLoad: true,
id: 'data_json',
idProperty: 'id',
fields: [ {name: 'id', type: 'int'}, 'name', {name:'add_date', type:'date', dateFormat: 'M$'}, 'price', 'kind', 'metacritic'],
listeners: { 'load': function(storename, records, options){
console.dir(this);
}},
writer: new Ext.data.JsonWriter()
})
the DUMP of the JSON it's receiving it's something like:
[
{"id":1,"name":"Guild Wars 2","add_date":"\/Date(1346104800000)\/","price":24.99,"kind":"MMO","metacritic":93},
{"id":2,"name":"Dark Souls: Prepare to Die Edition","add_date":"\/Date(1345759200000)\/","price":45.00,"kind":"actionrpg","metacritic":87},
{"id":3,"name":"Orcs Must Die! 2","add_date":"\/Date(1343599200000)\/","price":15.00,"kind":"action","metacritic":83}
]
the JSON is correctly decoded and the store is full of my records, but beware.. terrible things have happened!
All of the records have been marked as phantom = true, that doesn't let me correctly use ExtJS 3.4.x store.save() functionality
I've searched thoroughly on google about this issue, and (i think) it's connected to the fact the JsonReader doesn't associate the record id to the 'id' field i'm passing.
I have even specified idProperty: 'id'.
Help on this? I'm getting desperate, reading the extjs source about record creation is pure pain.
Try removing the:
id: 'data_json'
from your store. All the config options to a JsonStore are passed into the JsonReader that's automatically created, and that seems to be what's screwing it up.

Super new to ExtJS here. I've been trying to fetch data from a local server that provides the data from a database using ExtJS, but to no avail.
The database data can be fetched via Get request at http://localhost:3000/repository of my local machine. I generated a default ExtJS app and have a PersonalViewStore.js with the following proxy:
proxy: {
type: 'rest',
url: 'http://localhost:3000/repository',
reader: {
type: 'json',
rootProperty: 'data'
}
}
Note that the JSON database data can be fetched at 'http://localhost:3000/repository'.
Inside of that same PersonalViewStore.js file, I've got:
fields: [
'field1', 'field2'
],
autoLoad: true,
And inside of the PersonalView.js file, I have adapted the columns to be of the same names as the fields that I am fetching from:
columns: [
{
text: 'field1',
dataIndex: 'field1',
editable: true,
width: 100,
cell: {userCls: 'bold'}
},
{
text: 'field2',
dataIndex: 'field2',
editable: true,
width: 150
}
],
I've also ensured that the data is properly fetched via POSTMAN at http://localhost:3000/repository. What could go wrong then? Nothing is shown on my ExtJS Grid at http://localhost:1841/#personnelview where the Grid is supposed to be shown, except for the column names 'field1' and 'field2'
In our application we have a lot of name/value stores, and they are created at load time and put into a JSONStore like so :
Ext.create("Ext.data.JsonStore", {
data: data,
model: 'EM.model.controlUnit.CodeList',
storeId: "cl_" + tableId,
sorters: [{
sorterFn: aSorterFunction
}],
});
The model is pretty simple and looks like this :
Ext.define('EM.model.controlUnit.CodeList', {
extend: 'Ext.data.Model',
fields: [{
name: 'value', type: 'int'
}, {
name: 'label', type: 'string'
}, {
name: 'description', type: 'string'
}]
});
I thought stores were pretty interchangeable so I decided to use the store in the combo (There is no special combo store so I thought a JSONStore must be as good as a SimpleStore). I get the store like so :
var msDataStore = Ext.getStore("cl_t_cl_maritalstatus");
And use the store like so :
{
xtype: 'combo',
fieldLabel: 'Marital Status',
displayField: "label",
valueField: "value",
store: msDataStore
}
The combo is filled with the values from the store when I run the application, however, when I pop down the combo box, this error is thrown :
ext-debug-w-comments.js:9951 Uncaught
Ext.data.proxy.Server.buildUrl(): You are using a ServerProxy but have
not supplied it with a url.
I do not want any server proxy. These are simple locally stored name value collections.
Can JSONStores be used with combos?
If not. What is the best way to convert a JSONStore into something acceptable for the combo. I can chop, change, restructure the store object. But I just want to know if there is something simpler that I can do before going on some kind of long and pointless journey.
This problem is related 'proxy' property. Default proxy for JsonStore is 'ajax';
proxy: {
type : 'ajax',
reader: 'json',
writer: 'json'
}
You should override with 'memory' like that;
proxy: {
type: 'memory'
}
Your final store is;
Ext.create("Ext.data.JsonStore", {
data: data,
model: 'EM.model.controlUnit.CodeList',
storeId: "cl_" + tableId,
proxy: {
type: 'memory'
}
sorters: [{
sorterFn: aSorterFunction
}],
});
A JsonStore without URL is completely acceptable, but you have to make sure the combo does not trigger a load operation when clicking on the dropdown. This is done by adding to the combo definition the config option queryMode:'local':
{
xtype: 'combo',
fieldLabel: 'Marital Status',
displayField: "label",
valueField: "value",
queryMode: 'local',
store: msDataStore
}
edit http://jsfiddle.net/zns6B/4/ Added js fiddle link and running into a cannot get 'Fields' of undefined now
edit2 So i found that the second grids store model is correct with Sc.Model.B. But the records in the store have ids that are Sc.Model.A . So my store model is set to Sc.Model.B but the store is using Sc.Model.A . It still gets stores the data in the store but only as if the model was set to Sc.Model.A in the first place.
edit3 I have take all the creation of instance out of my ListGrid. I have instead added them when creating the list grid. I have added the following. This does not work either. I am at a lose for what to do.
var obj1 = Ext.create('Sc.ListGrid',{
title: "first Component",
foo: true,
id: 'firstGrid',
myStore: Ext.create('My.Store.MyStore',{model:Ext.create('My.Model.Model'});
renderTo: 'renderToMe1'
});
I am trying to generate these two grids. When foo == true i want it to generate a store with model A. When it equals false i want it to use model B. I have tried to just specifically add the My.Model.MyModel but that does not work. The second grid will somehow inherit the first models model. I have changed it just to try and use fields instead of using the model at all but the second grid still uses the first grids.
I have also tried declaring the Stores inside the initComponent as well but i get the same result either way.
var obj1 = Ext.create('Sc.ListGrid',{
title: "first Component",
foo: true,
id: 'firstGrid',
renderTo: 'renderToMe1'
});
var obj2 = Ext.create('Sc.ListGrid',{
title: "second Component",
foo: false,
renderTo: 'renderToMe2'
});
Sc.ListGrid
Ext.define('Sc.ListGrid', {
extend: 'Ext.grid.Panel',
title: 'Grid',
store: Ext.data.StoreManager.lookup('bleh'),
requires: ['stuff'],
columns: [
{ text: 'id', dataIndex: 'id' },
],
config:{
foo: null,
},
initComponent: function(){
if(this.foo == true){
Ext.apply(this,{
store: this.buildStore1()
});
}
if(this.foo == false){
Ext.apply(this,{
store: this.buildStore2()
});
}
this.callParent();
},
buildStore1:function(){
return Ext.create('Sc.Store.League.LeagueStore',{url:'somewhere',fields:["S"]});
},
buildStore2:function(){
return Ext.create('Sc.Store.League.LeagueStore',{url:'somewhere',fields:["A"]});
}
});
Also an example of a model i am trying to use as well.
Ext.define('Sc.Model.A', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'string'},
{name: 'type', type: 'string'},
{name: 'gamename', type: 'string'}
]
});
Ext.define('Sc.Model.B', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'string'},
{name: 'type', type: 'string'},
{name: 'gamename', type: 'string'},
{name: 'something1', type: 'string'},
{name: 'something2', type: 'string'},
]
});
It will create both grids and load the data from my webservice. When i check the grid with Sc.Model.B's data it will have id and type. But will not have any data for something1, and something2. My webserivce is returning json and all values are entered. There are no nulls. If i Ext.getCmp('firstGrid').getStore().getData(0); If i use Ext.getCmp('firstGrid').getStore() and check the model name. It shows Model B but reflects A
Do you need it to be done in the initComponent()??
This is a fiddle I saved from a while ago when I was trying to do something similar. If you need help tweaking it let me know and ill update it.
The main thing to note is the grid.reconfigure(store,columns);
That will change the grid's store and columns appropriately.

The issue was that the proxy wasn't being set or created properly because the proxy model was referencing the previous model instance. This is my solution
var themodel = 'A.Model.SomeModel';
var myProxy = new Ext.data.proxy.Ajax({
model: themodel,
url: url,
reader: {
type: 'json',
}
});
Ext.apply(this,{
columns: modelColumns.columns,
store: Ext.create('M.Store.MyStore',{
model: themodel ,
autoLoad: true,
proxy: myProxy
})
});
I'm working with ExtJS 4.1, I need to create a combo box containing a list of customers and I'd like to set a specific pre-selected item in it, but I don't know how to do it.
Here's the code to create my combo box:
xtype: 'combobox',
fieldLabel: 'customer',
name: 'customer_id',
allowBlank:false,
afterLabelTextTpl: required,
//data store
store: Ext.create('Ext.data.Store', {
autoDestroy: true,
model: 'customer_model',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'load.php?item=customer',
reader: {
type: 'json',
successProperty: 'success',
root: 'data'
}
}
}),
valueField: 'id',
displayField: 'company',
typeAhead: true,
queryMode: 'remote',
emptyText: ''
As you can see my combo box is filled by a data store, that data store is built on a data model called 'customer_model'. Here's the code for data model:
Ext.define('customer_model', {
extend: 'Ext.data.Model',
fields: [
{type: 'int', name: 'id'},
{type: 'string', name: 'company'},
{type: 'string', name: 'vat'},
{type: 'string', name: 'ssn'},
{type: 'int', name: 'ref_id'}
]
});
Well, I'd like to configure my combo box so that a certain item, for instance the customer having id equals to 1, is automatically selected when the page is loaded.
Can anyone help me ?
Thanks in advance.
Enrico.
In Ext.js 3.2.1, you are able to do this:
combobox.setValue(id);
This assumes that the combobox is configured to use id as the valueField. Your code seems to indicate that this is the case. You would also need to have a reference to the id value that you want to set the value to. The caveat here is that you need to make sure that this code only executes after the model is loaded, otherwise the combobox won't have anything to display. You can ensure this by setting the combobox in the callback method of the ajax call or in the load event of the store.
I've looked into the documentation for Ext.js 4.1, and this method seems to still be there. I believe this should do the trick.
Edit: clarity
Thanks to Christopher help I wrote a working version of my code, I've decided to post it here, maybe it could be useful for someone...:
buttons: [{
text: 'Load',
handler: function(){
var form = this.up('form').getForm();
var combobox = form.findField('ref_id_combo');
formPanel.getForm().load({
url: <?php echo "'update_loader.php?id=".$_GET['id']."&item=customer',"; ?>
waitMsg: 'Loading...',
success: function(form, action) {
combobox.setValue(<?php echo get_property_id("ref_id","customer",$_GET['id']);?>);
}
});
}
}
Programatically with combo.setValue(val) or declaratively:
{
xtype: 'combo',
value: val,
...
}
if you want to select the first value of a store you can do
combo.select(combo.getStore().getAt(0))
it will select the value at index 0 of the combo store
If you create your own store first, you can use afterrender: function(combo){}
listeners: {
afterrender: function (combo) {
var record = yourStore.getAt(0);
var abbr= record.get('abbr');
combo.setValue(abbr);
}
}
As part of my EXTJS 4 learning process, I am trying to establish a simple process of database connection - loading a value in a data Store - taking the value and placing it in a dataField.
The data is loaded fine from the php script and placed into the Store via a json call. (as confirmed through FireBug)
However, the dataField, does not seem to be able to load the value.
Here is what I have so far:
//Model definition
Ext.define('FingerModel', {
extend: 'Ext.data.Model',
fields: [
{name: 'name', type: 'string'}
]
});
//Store Definition
var est_data = new Ext.data.Store({
model: 'FingerModel',
proxy: {
type: 'ajax',
url: 'finger.php',
extraParams: {opt: 'getName'},
reader: {
type: 'json',
root: 'results',
totalProperty: 'total'
}
},
autoLoad: true,
// turn off remote sorting
remoteSort: false
});
//Form definition
var fingerForm = Ext.create('Ext.form.Panel', {
width: 500,
title: 'Finger',
waitMsgTarget: true,
items: [{
xtype: 'fieldset',
title: 'Finger Form',
items: [{
xtype:'textfield',
fieldLabel: 'Location Name',
name: 'name'
}]
}]
});
fingerForm.getForm().loadRecord(FingerModel);
Anybody see anything obvious that I'm doing wrong?
Thanks in advance.
M.
Ext.form.field.Text does not have a 'store' property. How would it know which row of the store to use?
You should use Form.loadRecord() to load the model into the form, and it will set form fields with the same name as the model field names.
