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'
}
},

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.
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-
im new with Sencha Touch 2 and i have a problem working with drupal, json, etc...
It's simple but i can't take the solution.
I have a list who is completed by a json. This json comes from Drupal7 views in json format.
In my view i have something like that:
var listaArtistas = {
xtype: 'list',
title: 'Artistas',
height: 240,
store: {
autoLoad: true,
fields: ['node'],
proxy: {
type: 'ajax',
url: 'http://localhost/json-artistas',
reader: {
type: 'json',
rootProperty: 'nodes'
}
}
},
listeners: {
itemtap: function(lista,index,target,record,e,eOpts)
{
var artistDetail = new Ext.create('app.view.ArtistDetail');
panelHomeNav.push(artistDetail);
}
},
itemTpl: tpl
};
This code Works for me. And complete de list with the artist.
Now i click in the artist and goes to another view (artistDetail). But to show propertly this list with details of the artist, need the ID of the artist who i cliked before.
I need something like this in artistDetail.... url: 'http://localhost/json-artistasDetail'+NID, where the NID is the ID of the artist who is in the list before.
I don't know how to pass this parameters between 2 views in Sencha
Thanks for help... or read :D
Many options are possible, here is one: after creating the detail view, you could set a dedicated property, as an example:
var artistDetail = new Ext.create('app.view.ArtistDetail');
artistDetail.setArtistID(artistID);
panelHomeNav.push(artistDetail);
I have the following nested list (only on item in at present to make testing easier).
It works ok, but how can I display a normal page view that has html within it or loads the html page in.
var data = {text: 'Top List',
items: [{
text: 'List item',
items: [{text: 'Selected Page'}]
}]
};
Ext.regModel('ListItem', {
fields: [{name: 'text', type: 'string'}]
});
var store = new Ext.data.TreeStore({
model: 'ListItem',
root: data,
proxy: {
type: 'memory',
reader: {
type: 'tree',
root: 'items'
}
}
});
var nestedList = new Ext.NestedList({
fullscreen: true,
displayField: 'text',
title: 'Theatres',
store: store
});
App.views.Pastcard = Ext.extend(Ext.Panel, {
title: "past",
iconCls: "add",
items: [nestedList]
});
Ext.reg('HomeAbout', App.views.Pastcard);
SO want the user selects the 'Selected Page' item it opens the the detailed view page and html information, preferably from an external source to limit the amount of code on one page.
EDIT
I think i can try and be a little clearer.
Below is my nested list.
var data = {text: 'My List',
items: [{
text: 'First List Item',
items: [{text: 'Sub list one'}, {text: 'Sub list Two'}]
},
{
text: 'Second List Item',
items: [{text: 'Sub list one'},{text: 'Sub list Two'}]
}
]
};
When me / the user clciks on the lsit and gets to the sublist then clicks on the list item called say "Sub list Two" then at the moment it opens to a blank page as there are no more lists, but instead I woudl liek to dispaly a normal page with details on, that can scroll and everything.
At the moment I dotn need to worry about loading in my json dynamiocally as I woudl liek to get a working model before I move on to that side of it
Thsi is not a phonegap app but a standard web app to be view online via mobiles.
* Edn of Edit **
Thanks
To use external source use a store with ajax proxy check this http://dev.sencha.com/deploy/touch/docs/?class=Ext.data.Store.
To display HTML you can use just html: '<h1>Selected Page</h1>', styleHtmlContent:true,
instead of text:'Selected Page'
The best way is to load JSON objects from:
var myStore = new Ext.data.Store({
model: 'User',
proxy: {
type: 'ajax',
url : '/users.json',
reader: {
type: 'json',
root: 'users'
}
},
autoLoad: true
});
then instead of html or text property use a template to display it:
tpl:[
'<h4>Email</h4>',
'<tpl for="emails">',
'<div class="field"><span class="label">{type}: </span>{value}</div>',
'</tpl>'
]
Check this tutorial http://www.sencha.com/learn/a-sencha-touch-mvc-application-with-phonegap/ and the API docs http://dev.sencha.com/deploy/touch/docs/ for more information.
Update
To the last items i.e. to the sub lists add this leaf: true then have add a handler fir onItemDisclosure to the list. You can get the record clicked as first argument passed to the event. Then you can use that object to display it on a different panel.
You can still use the tutorial above, just substitue the code where the contacts are fetched from the phone with some static data.
From that tutorial this is the part you need
app.views.Viewport = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
initComponent: function() {
//put instances of cards into app.views namespace
Ext.apply(app.views, {
contactsList: new app.views.ContactsList(),
contactDetail: new app.views.ContactDetail(),
contactForm: new app.views.ContactForm()
});
//put instances of cards into viewport
Ext.apply(this, {
items: [
app.views.contactsList,
app.views.contactDetail,
app.views.contactForm
]
});
app.views.Viewport.superclass.initComponent.apply(this, arguments);
}});
This is the main panel where the list and the details panel are contained. You handle the onItemDisclosure event on the list, get the record that was clicked on, update the details panel with that data and the switch to that panel with
app.views.viewport.setActiveItem(
app.views.contactsList, options.animation
);
I know the typical reason for a DataView to be blank is because the model or JSON is wrong. From what I can tell, mine is right... so I'm not sure why my DataView is blank.
Controller
rpc.controllers.AboutController = new Ext.Panel({
id: 'rpc-controllers-AboutController',
title: 'About',
iconCls: 'info',
layout: 'card',
scroll: 'vertical',
items: [rpc.views.About.index],
dockedItems: [{ xtype: 'toolbar',
title: 'RockPointe Church | Mobile'
}],
listeners: {
activate: function () {
if (rpc.stores.AboutStore.getCount() === 0) {
rpc.stores.AboutStore.load();
}
}
}
});
View
rpc.views.About.index = new Ext.DataView({
id: 'rpc-views-about-index',
itemSelector: 'div.about-index',
tpl: '<tpl for="."><div class="about-index">{html}</div></tpl>',
store: rpc.stores.AboutStore,
fullscreen: true,
scroll: 'vertical'
});
Store
rpc.stores.AboutStore = new Ext.data.Store({
id: 'rpc-stores-aboutstore',
model: 'rpc.models.AboutModel',
autoLoad: true,
proxy: {
type: 'scripttag',
url: WebService('About', 'Index'),
method: 'GET',
reader: {
type: 'json',
root: 'results'
},
afterRequest: function (request, success) {
if (success) {
console.log("success");
} else {
console.log("failed");
}
console.log(request);
}
}
});
rpc.stores.AboutStore.proxy.addListener('exception', function (proxy, response, operation) {
console.log(response.status);
console.log(response.responseText);
});
Model
rpc.models.AboutModel = Ext.regModel('rpc.models.AboutModel', {
fields: ['html']
});
JSON
mycallback({"results":{"html":"... content removed for brevity ..."},"success":true});
Can anyone see what I might be doing wrong here?
There are no console/javascript errors. And the resources are showing that I am in fact pulling down the JSON from the WebService.
If I use console.log(rpc.stores.AboutStore.getCount()); inside my activate listener on the AboutController, the result is always 0, and I'm not entirely sure why
here's the staging app if you'd like to see the request
http://rpcm.infinitas.ws/ (note, this link will expire at some point)
Try returning your json value as an array instead of an object. I think Ext is expecting an array of records instead of just one.
For example
"{results : [{"html": "Your html"}]}"
