Sencha Touch List refresh from store - sencha-touch

I have a simple List inside a container that I would like to see refreshed with new items when it is activated.
In my controller, I have an event for this:
onActivate: function() {
var that = this;
var store = this.getApprovalRequestsStore();
store.getProxy().setUrl('http://mobile-approvals-services.example.com/'+ Global.approvalsListUri + Approvals.app.user);
store.load({
callback: function (records, model) {
debugger;
that.getApprovalsList().refresh();
}
});
},
And in my list, I have a tpl for the items that come back from the store (verified I have items coming back from store at break point above), yet no items are shown:
Ext.define('Approvals.view.approvals.List', {
extend: 'Ext.List',
xtype: 'approvalsList',
config: {
itemId: 'ApprovalsList',
store: 'ApprovalRequests',
itemHeight: 70,
variableHeights: false,
pressedDelay: 0,
emptyText: "<div>No Approvals Found</div>",
loadingText: "Loading...",
onItemDisclosure: false,
itemTpl: '<div class="listView">Request For: {requestedFor}</div>',...
Is there something flawed in my approach?

It was a problem with the reader. Once I set totalProperty and successProperty to values being returned from the service it worked. WTHO.

rally iteration combobox returns empty

I'm new to rally app SDK and trying to do the tutorials (from Youtube and from rally site)
when I'm trying to create an iterationComboBox the object is created but with no values ("There are no Iterations defined").
i tried to run both the video tutorial code from github (session_4_interactive_grid)

i'm getting user stories data when running code from session 3 on the video,by creating a store of user stories. I googled it and searched here for duplicates but with no successso far, so what can be the issue?
Thanks!
I copied the code you posted, both apps, without making any changes, ran the apps and the iteration box was populated in both cases. It's not the code.
Maybe if you are getting "There are no Iterations defined" there are no iterations in your project?
The second code you posted which you copied from the example in the documentation has a bug in it and even though the iteration combobox is populated, the cards do not show on a board. DevTools console has error: "Cannot read property 'refresh' of undefined".
I have a working version of this app in this github repo.

Sencha List does not appear when trying to add() it to pabel

This is really wired. I have a tab in a TabPanel that I want to refresh every time the user taps it. In the tab there should be a list of things. when i am trying to add the list to the panel(the tab container), it is just do not appear! when i try to add other things they aper normally!
For example:
var listConfiguration = this.getListConfiguration();
var myPanel = Ext.create('Ext.Panel', {
html: 'This will be added to a Container'
});
Ext.getCmp('Peoplebutton').add(listConfiguration);
Ext.getCmp('Peoplebutton').add(myPanel);
This code gets the html perfectly in the place! but the list is not shown! The list code is working fine, I have checked it several times...
I would be very happy if someone can help me (:
The list code, working fine for sure
getListConfiguration: function() {
var store = Ext.create('Ext.data.Store', {
fields: ['firstName', 'lastName'],
sorters: 'firstName',
autoLoad: true,
grouper: {
groupFn: function(record) {
return record.get('firstName')[0];
}
},
proxy: {
type: 'ajax',
url: 'contacts.json'
}
});
return {
xtype: 'list',
id: 'list',
itemTpl: '{firstName} ,{lastName}',
grouped: true,
indexBar: true,
infinite: true,
useSimpleItems: true,
variableHeights: true,
striped: true,
ui: 'round',
store: store
};
}
It should be an issue with the height of the list component.
Try adding a fixed height to the list, or maybe flex: 1.
Hope it helps-

sencha touch accordion list not loading data

I can't figure out why my data won't load to my AccordionList element from here:
https://github.com/kawanoshinobu/Ext.ux.AccordionList
I'm creating it within a panel like so:
{
xtype: 'accordionlist',
store: Ext.create('Rks.store.Bcks'),
flex: 1
},
It calls a store which is defined like so:
Ext.define('Rks.store.Bcks', {
extend: 'Ext.data.TreeStore',
requires: ['Rks.model.Bck'],
config: {
itemId: 'bks',
model: 'Rks.model.Bck',
defaultRootProperty: 'items',
proxy: {
type: 'ajax',
url: 'path/to/ajax',
},
autoLoad: false,
listeners:{
load: function( me, records, successful, operation, eOpts ){
console.log("data loaded", records);
}
}
}
});
When I call the view which contains the accordion, the console logs what appears to be a good object:
items: [{bck_id:3, author_id:1, title:test, items:[{c_id:2, bck_id:3, title:choice1, leaf:true}]}]
But nothing shows up. The panel is empty and no accordion items show.
However, when I replace the proxy with inline JSON, everything looks fine:
Ext.define('Rks.store.Bcks', {
extend: 'Ext.data.TreeStore',
requires: ['Rks.model.Bck'],
config: {
itemId: 'bks',
model: 'Rks.model.Bck',
defaultRootProperty: 'items',
root: {
items: [
{ bck_id: 1, author_id: 1, title: 'bck1', items: [ {c_id: 1, bck_id: 1, title: 'choice1', leaf: true} ] }
]
}
autoLoad: false,
listeners:{
load: function( me, records, successful, operation, eOpts ){
console.log("data loaded", records);
}
}
}
});
Here the items show up in the accordion. I can't figure out why the second example works and the first doesn't. Is there something special I should be doing when calling the store proxy for Accordion?
UPDATE: I have managed to get the accordion list to display data, but when I change the url of the store and reload it, the store reloads but the accordion list does not update. The accordion list continues to display the data it receives from the first URL, not from reloads with modified URLS.
Thanks
I think I figured this out. For the accordionlist component, you need to do like so:
var accordionlist = Ext.ComponentQuery.query('rdb #rdb1')[0];
var brickstore = Ext.getStore('bcs');
bcs.removeAll();
bcs.getProxy().setUrl('newurl');
accordionlist.setStore(bcs);
accordionlist.load();
basically, manually remove all items, set the new url, set the store on the list, then load the list.
I think there was a problem with your proxy configuration. First, remove the defaultRootProperty config (which is out of proxy config), then try this:
proxy: {
type: 'ajax',
url: (your ajax url),
reader: {
type: 'json',
rootProperty: 'items'
}
},

Nested grid in ExtJS 4.1 using Row Expander

On the front-end I have a Calls grid. Each Call may have one or more Notes associated with it, so I want to add the ability to drill down into each Calls grid row and display related Notes.
On the back-end I am using Ruby on Rails, and the Calls controller returns a Calls json recordset, with nested Notes in each row. This is done using to_json(:include => blah), in case you're wondering.
So the question is: how do I add a sub-grid (or just a div) that gets displayed when a user double-clicks or expands a row in the parent grid? How do I bind nested Notes data to it?
I found some answers out there that got me part of the way where I needed to go. Thanks to those who helped me take it from there.
I'll jump straight into posting code, without much explanation. Just keep in mind that my json recordset has nested Notes records. On the client it means that each Calls record has a nested notesStore, which contains the related Notes. Also, I'm only displaying one Notes column - content - for simplicity.
Ext.define('MyApp.view.calls.Grid', {
alias: 'widget.callsgrid',
extend: 'Ext.grid.Panel',
...
initComponent: function(){
var me = this;
...
var config = {
...
listeners: {
afterrender: function (grid) {
me.getView().on('expandbody',
function (rowNode, record, expandbody) {
var targetId = 'CallsGridRow-' + record.get('id');
if (Ext.getCmp(targetId + "_grid") == null) {
var notesGrid = Ext.create('Ext.grid.Panel', {
forceFit: true,
renderTo: targetId,
id: targetId + "_grid",
store: record.notesStore,
columns: [
{ text: 'Note', dataIndex: 'content', flex: 0 }
]
});
rowNode.grid = notesGrid;
notesGrid.getEl().swallowEvent(['mouseover', 'mousedown', 'click', 'dblclick', 'onRowFocus']);
notesGrid.fireEvent("bind", notesGrid, { id: record.get('id') });
}
});
}
},
...
};
Ext.apply(me, Ext.apply(me.initialConfig, config));
me.callParent(arguments);
},
plugins: [{
ptype: 'rowexpander',
pluginId: 'abc',
rowBodyTpl: [
'<div id="CallsGridRow-{id}" ></div>'
]
}]
});

Sencha : can't call method "update" of undefined

Here, i'm registering my app:
App = new Ext.Application({
name: "App",
launch: function() {
this.views.viewport = new this.views.Viewport();
}
});
This is the way i register new panels and components. I put each of them into seperate js files.
App.views.Viewport = Ext.extend(Ext.TabPanel, {
fullscreen: true,
tabBar: {
dock: 'bottom',
layout: {
pack: 'center'
}
},
items: [
{
xtype: 'cPanel'
},
{
xtype: 'anotherPanel'
}
]
});
// register this new extended type
Ext.reg('App.views.viewport', App.views.Viewport);
I added the other components in the same manner.
In one my components which is a list view, I want to change the container panel's activeItem with another panel when tappen on an item, like this: ( Viewport contains this container panel)
App.views.ListApp = Ext.extend(Ext.List, {
store: App.store,
itemTpl: "...",
onItemDisclosure: function(record) {
App.detailPanel.update(record.data);
App.cPanel.setActiveItem("detailPanel");
},
listeners: {
itemtap: function(view, index, item, e) {
var rec = view.getStore().getAt(index);
App.views.detailPanel.update(rec.data);
App.views.cPanel.setActiveItem("detailPanel", {type:"slide", direction: "left"});
}
}
});
App.views.detailPanel.update(rec.data);
But it says: can't call method "update" of undefined
I tried different variations on that line, like:
App.detailPanel.update(rec.data);
and i tried to give detailPanel and cPanel ids, where they were added to their container panel, and tried to reach them with Ext.get(), but none of these worked.
What is the problem here?
And any other advices would be appreciated.
Thanks.
The lazy way: give the panels ids and use:
Ext.getCmp(id)
The recommended way: Assign itemId to your panel and use:
App.views.viewport.getComponent(itemId)
This will allow you to have more than one instance of the same component at aby given time, the first example is not valid cause you can only have a singular id in the DOM tree.
Also getComponent only works for components stored in the items collection.
