I am new to extjs.I want to associate a store on selecting a menu item from Ext.menu.Menu. I am using extjs 4.1.0. I searched on the net even went through sencha doc but I couldn't find any way to achieve this.
Is there some way to achieve it?
Thanks in advance.
I'm using a menu with a store in a project. Here's an example:
Ext.define("Ext.ux.menu.DynamicMenu", {
extend: "Ext.menu.Menu",
alias: 'widget.dynamicmenu',
loaded: false,
loadMsg: 'Loading...',
store: undefined,
icon: '',
constructor: function (config) {
var me = this;
Ext.apply(me, config);
me.callParent();
},
initComponent: function () {
var me = this;
me.callParent(arguments);
me.on('show', me.onMenuLoad, me);
listeners = {
scope: me,
load: me.onLoad,
beforeload: me.onBeforeLoad
};
me.mon(me.store, listeners);
},
onMenuLoad: function () { var me = this; if (!me.store.loaded) me.store.load(); },
onBeforeLoad: function (store) { this.updateMenuItems(false); },
onLoad: function (store, records) { this.updateMenuItems(true, records); },
updateMenuItems: function (loadedState, records) {
var me = this;
me.removeAll();
if (loadedState) {
me.setLoading(false, false);
Ext.Array.each(records, function (record, index, array) {
me.add({
text: record.get('DisplayName'),
data: record,
icon: me.icon
});
});
me.store.loaded = true;
}
else {
me.add({ width: 75, height: 40 });
me.setLoading(me.loadMsg, false);
}
me.loaded = loadedState;
}
});
I found this one on the sencha forums if IIRC, but can't find the link anymore. I made some tweaks for icons etc, ...
On the Ext.Array.each(records, ....
You'll need to define your own logic, It's depending on your model. My model has a DisplayName which I use to show as text. I also stock my record in a data property I made in the menu item. You're completely free there.
Good luck!

I'm new in extJS and i've been working in an app for some time.
My problem is that I have an app with an MVC architecture and as I instatiate the controller I declare de stores. But when I run this app in the browser, for some reason the controller is trying to get the store from my controller folder.
I have other controllers runing in my app and all of them looks for the store in the stores folder.
Does anyone have a clue about this issue?
Thanks

An ExtJs Controller pulls in the specified store files before rendering its UI. Assuming that you have not created any store files (assumption form your init function where you created the store if they do not exist), it first searches the store files to load them into the memory.
Another possible problem may be the store has a different namespace than that of the application, you will need to specify the full class name as well as define a path in the Loader's paths config or setPath method.
Refer doc ExtJs Controller's Stores.

Until now, I have been querying the data stores using Rally App SDK, however, this time I have to update a story using the js sdk. I tried looking up for examples for some sample code that demonstrates how the App SDK can be used to update/add values in Rally. I have been doing CRUD operations using Ruby Rally API but never really did it with the app sdk.
Can anyone provide some sample code or any link to where I could check it out?
Thanks
See this help document on updating and creating reocrds. Below are examples - one updates a story, the other creates a story. There is not much going on in terms of UI: please enable DevTools console to see console.log output.
Here is an example of updating a Defect Collection on a User Story:
Ext.define('CustomApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
console.log("launch");
Rally.data.ModelFactory.getModel({
type: 'User Story',
success: this._onModelRetrieved,
scope: this
});
},
_onModelRetrieved: function(model) {
console.log("_onModelRetrieved");
this.model = model;
this._readRecord(model);
},
_readRecord: function(model) {
var id = 13888228557;
console.log("_readRecord");
this.model.load(id, {
fetch: ['Name', 'Defects'],
callback: this._onRecordRead,
scope: this
});
},
_onRecordRead: function(record, operation) {
console.log('name...', record.get('Name'));
console.log('defects...', record.get('Defects'));
if(operation.wasSuccessful()) {
//load store first by passing additional config to getCollection method
var defectStore = record.getCollection('Defects', {
autoLoad: true,
listeners: { load: function() {
//once loaded now do the add and sync
defectStore.add({'_ref':'/defect/13303315495'});
defectStore.sync({
callback: function() {
console.log('success');
}
});
}}
});
}
},
});
Here is an example of creating a user story, setting a project and scheduling for an iteration:
Ext.define('CustomApp', {
extend: 'Rally.app.TimeboxScopedApp',
componentCls: 'app',
scopeType: 'iteration',
comboboxConfig: {
fieldLabel: 'Select an Iteration:',
labelWidth: 100,
width: 300
},
addContent: function() {
this._getIteration();
},
onScopeChange: function() {
this._getIteration();
},
_getIteration: function() {
var iteration = this.getContext().getTimeboxScope().record.get('_ref');
console.log('iteration',iteration);
if (!this.down('#b2')) {
var that = this;
var cb = Ext.create('Ext.Container', {
items: [
{
xtype : 'rallybutton',
text : 'create',
id: 'b2',
handler: function() {
that._getModel(iteration);
}
}
]
});
this.add(cb);
}
},
_getModel: function(iteration){
var that = this;
Rally.data.ModelFactory.getModel({
type: 'UserStory',
context: {
workspace: '/workspace/12352608129'
},
success: function(model) { //success on model retrieved
that._model = model;
var story = Ext.create(model, {
Name: 'story 777',
Description: 'created via appsdk2'
});
story.save({
callback: function(result, operation) {
if(operation.wasSuccessful()) {
console.log("_ref",result.get('_ref'), ' ', result.get('Name'));
that._record = result;
that._readAndUpdate(iteration);
}
else{
console.log("?");
}
}
});
}
});
},
_readAndUpdate:function(iteration){
var id = this._record.get('ObjectID');
console.log('OID', id);
this._model.load(id,{
fetch: ['Name', 'FormattedID', 'ScheduleState', 'Iteration'],
callback: function(record, operation){
console.log('ScheduleState prior to update:', record.get('ScheduleState'));
console.log('Iteration prior to update:', record.get('Iteration'));
record.set('ScheduleState','In-Progress');
record.set('Iteration', iteration);
record.set('Project', '/project/12352608219')
record.save({
callback: function(record, operation) {
if(operation.wasSuccessful()) {
console.log('ScheduleState after update..', record.get('ScheduleState'));
console.log('Iteration after update..', record.get('Iteration'));
}
else{
console.log("?");
}
}
});
}
})
}
});
In ExtJs, there are many options to filter a grid. There are two nice examples in the documentation, like referenced in this question.
Remote filtering
Local filtering
However, having the filter hidden in the default dropdown menu of Ext.ux.grid.FiltersFeature looks really awkward for me. A good ergonomic choice would to create search fields in the column headers, like #Ctacus shows in his question.
How can this be achieved ?
After quite much research through the sparse documentation, and thanks to great questions and answers in SO, I came up with a simple class, that adds this functionality and and allows for configurations.
It looks like this:
You add this field in your grid like this:
Ext.define('Sandbox.view.OwnersGrid', {
extend: 'Ext.grid.Panel',
requires: ['Sandbox.view.SearchTrigger'],
alias: 'widget.ownersGrid',
store: 'Owners',
columns: [{
dataIndex: 'id',
width: 50,
text: 'ID'
}, {
dataIndex: 'name',
text: 'Name',
items:[{
xtype: 'searchtrigger',
autoSearch: true
}]
},
The following configs are possible, and work like described in the doc for Ext.util.Filter:
anyMatch
caseSensitive
exactMatch
operator
additionnaly you can use autoSearch. If true, the filter searches as you type, if false or not set, one has to click on the search icon to apply the filter.
ExtJs 5 / 6 Source:
Ext.define('Sandbox.view.SearchTrigger', {
extend: 'Ext.form.field.Text',
alias: 'widget.searchtrigger',
triggers:{
search: {
cls: 'x-form-search-trigger',
handler: function() {
this.setFilter(this.up().dataIndex, this.getValue())
}
},
clear: {
cls: 'x-form-clear-trigger',
handler: function() {
this.setValue('')
if(!this.autoSearch) this.setFilter(this.up().dataIndex, '')
}
}
},
setFilter: function(filterId, value){
var store = this.up('grid').getStore();
if(value){
store.removeFilter(filterId, false)
var filter = {id: filterId, property: filterId, value: value};
if(this.anyMatch) filter.anyMatch = this.anyMatch
if(this.caseSensitive) filter.caseSensitive = this.caseSensitive
if(this.exactMatch) filter.exactMatch = this.exactMatch
if(this.operator) filter.operator = this.operator
console.log(this.anyMatch, filter)
store.addFilter(filter)
} else {
store.filters.removeAtKey(filterId)
store.reload()
}
},
listeners: {
render: function(){
var me = this;
me.ownerCt.on('resize', function(){
me.setWidth(this.getEl().getWidth())
})
},
change: function() {
if(this.autoSearch) this.setFilter(this.up().dataIndex, this.getValue())
}
}
})
For ExtJs 6.2.0, the following bug and its workaround is relevant to this, else the column cannot be flexed.
ExtJs 4 Source:
Ext.define('Sandbox.view.SearchTrigger', {
extend: 'Ext.form.field.Trigger',
alias: 'widget.searchtrigger',
triggerCls: 'x-form-clear-trigger',
trigger2Cls: 'x-form-search-trigger',
onTriggerClick: function() {
this.setValue('')
this.setFilter(this.up().dataIndex, '')
},
onTrigger2Click: function() {
this.setFilter(this.up().dataIndex, this.getValue())
},
setFilter: function(filterId, value){
var store = this.up('grid').getStore();
if(value){
store.removeFilter(filterId, false)
var filter = {id: filterId, property: filterId, value: value};
if(this.anyMatch) filter.anyMatch = this.anyMatch
if(this.caseSensitive) filter.caseSensitive = this.caseSensitive
if(this.exactMatch) filter.exactMatch = this.exactMatch
if(this.operator) filter.operator = this.operator
console.log(this.anyMatch, filter)
store.addFilter(filter)
} else {
store.filters.removeAtKey(filterId)
store.reload()
}
},
listeners: {
render: function(){
var me = this;
me.ownerCt.on('resize', function(){
me.setWidth(this.getEl().getWidth())
})
},
change: function() {
if(this.autoSearch) this.setFilter(this.up().dataIndex, this.getValue())
}
}
})
In my code I use MVC architecture. My view Component looks like this:
Ext.define('calendar.view.event', {
extend: 'Ext.Component',
alias: 'widget.event',
renderTo: Ext.getBody(),
initComponent:function(){
this.addEvents('eventClick');
this.callParent(arguments);
},
afterRender: function() {
this.mon(this.el, 'click', this.eventClick, this); //mon( item, ename, [fn], [scope], [options] ) - zkratka pro addManagedListener.
this.callParent(arguments);
},
eventClick: function (ev, t) {
var height = this.getHeight();
this.fireEvent('eventClick', this, height, ev);
}
});
Im firing Event on click for controller which is like this:
Ext.define('calendar.controller.eventsChange', {
extend: 'Ext.app.Controller',
views: ['event'],
init: function () {
this.control({
'event': {
eventClick: function (callerObject) {
this.editEvent(callerObject)
}
}
});
},
editEvent: function (callerObject) { //oznaci jako editovatelny
callerObject.get
if(callerObject.hasCls('SpecEv') || callerObject.hasCls('activeEvent'))
{
if (callerObject.hasCls('activeEvent'))
{
callerObject.removeCls('activeEvent');
callerObject.addCls('SpecEv');
this.application.fireEvent('reRender');
}
else
{
console.log(callerObject);
callerObject.addCls('activeEvent');
callerObject.removeCls('SpecEv');
Ext.apply(callerObject, {
resizable: {
pinned:true,
dynamic:true
},
draggable: true,
});
callerObject.setLocalX(0);
var parentWidth = Ext.getCmp('SpecEv').getWidth();
callerObject.setWidth(parentWidth);
}
}
}
});
The problem comes when with
Ext.apply(callerObject, {resizable: {
pinned:true,
dynamic:true
},
draggable: true,
});
When console.log shows me the object after my apply, it says draggable:true and resizable:true. Does anyone know where the problem is?
Thanks for reponses.
It can't works, because your code only set configuration properties, which are handled only when component is initializing. So when you set these properties on already constructed object nothing happen. Component resizability and draggability will not be initialized automatically after setting these properties.
You can try use Ext.Component initResizable and initDraggable methods. But these methods are internal and undocumented.
callerObject.initResizable({
pinned:true,
dynamic:true
});
callerObject.initDraggable();
Also you can try setup Ext.util.ComponentDragger and Ext.resizer.Resizer for your existing component manually.
