I am using Ext.plugin.PullRefresh plugin which is working fine when I directly run my app on
the browser but when I build my production through sencha cmd 4.0 its duplicating my content whenever I pull to refesh.
I have already used idProperty on my model.
My Jsonp:
callback({"Message":"Success","Post":[{"id":"35","UserId":"faisalkhalid690","Content":"lol","Time":"2013-12-03 05:28:15"},{"id":"50","UserId":"faisalkhalid","Content":"asdfasdfasdf","Time":"2013-12-03 05:52:27"},{"id":"51","UserId":"faisalkhalid","Content":"sadfasdfasdf","Time":"2013-12-03 05:52:38"},{"id":"52","UserId":"faisalkhalid","Content":"holloa","Time":"2013-12-03 05:52:50"},{"id":"70","UserId":"faisalkhalid690","Content":"hello","Time":"2013-12-04 23:22:52"}]});
Model:
Ext.define('talkbag.model.Comments', {
extend: 'Ext.data.Model',
config: {
idProperty: 'id',
fields: [
{ name: 'id', type: 'auto' },
{ name: 'UserId', type: 'auto' },
{ name: 'Content', type: 'auto' },
{ name: 'Time', type: 'auto' }
]
}
});
Store:
Ext.define('talkbag.store.Comments', {
extend:'Ext.data.Store',
storeId:'Comments',
config:{
autoLoad: true,
model:'talkbag.model.Comments',
proxy: {
type: 'jsonp',
url : 'http://www.litemake.com/ViewComments.php?Pid='+talkbag.User.PostId,
reader: {
type: 'json',
rootProperty: 'Post'
}
}
}
});
View:
Ext.define('talkbag.view.ViewPost.ViewCommentDetail', {
extend:'Ext.Panel',
xtype:'ViewCommentDetail',
requires:['Ext.plugin.PullRefresh'],
extend:'Ext.Panel',
config:{
layout:'vbox',
items:
[{
xtype:'appbar',
},{
flex:1,
xtype:'list',
store:'Comments',
plugins: [
{
xclass: 'Ext.plugin.PullRefresh',
pullRefreshText: 'Pull down for new Comments',
}
],
disableSelection :true,
itemTpl:'<table><tr><td width="80px"><table align="center"><tr><td align="center"><img src="http://www.litemake.com/getPic.php?userId={UserId}" heigth="30px" width="30px"/></td></tr><tr><td style="font-size:0.6em">{UserId}</td></tr></table></td><td style="padding-left:20px"><table><tr><td style="font-size:0.7em; padding:0px 0px 5px 0px">{Content}</td></tr><tr><td style="font-size:0.5em">{Time}</td></tr></table></td></tr></table>',
}]
}
});
Have you added a requires for it? that is
requires:['Ext.plugin.PullRefresh']
or something like that?
I have also faced this type of duplicating record issue, In my case i have put an autogenerated id field in my json, like this way
{
"items": [
{
"id": 0,
"ContactName": "Aanitha Ps",
},
{
"id": 1,
"ContactName": "Aby",
}
]
}
and reference that id field in my model, i think sencha some times not taking model default id field.

In my model, I have the following code:
Ext.define('Proximity.model.CandidateblocklistModel', {
extend: 'Ext.data.Model',
requires: ['Ext.data.proxy.LocalStorage'],
config: {
store:'Proximity.store.CandidateblockStore',
fields: [
{ name: 'id', type: 'id' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'designation', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'experience', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidateblock',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
"id": localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'name'
})
]
}
}
}
});
The id in the local storage is already set before calling this model. I can see the id in localStorage by inspect element in Chrome, and I did get the value of it in other section. But I only can't get it in my model when I am trying to use it in proxy. I want to get data from my web service based on the value of the localStorage.
Code in my proxy:
extraParams: {
"id": localStorage.getItem('id')
},
I want to get the id from localStorage here.
Please help me.
I think the following code works
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/candidate/getcandidatebest',
withCredentials: false,
useDefaultXhrHeader: false,
extraParams: {
id: localStorage.getItem('id')
},
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id',
property: 'id'
})
]
}
}
and then use the filtering facility of store to pass the localstorage value. To do that give filter permission remoteFilter: true, this.
Ahh i found an awesome trick. Instate of setting extraParams in your Model, set it in the store of the same model.
My new code is as follows.
Ext.define('Proximity.model.RecruiterbestlistModel', {
extend: 'Ext.data.Model',
config: {
store:'Proximity.store.RecruiterbestStore',
fields: [
{ name: 'id', type: 'int' },
{ name: 'name', type: 'string' },
{ name: 'img', type: 'string' },
{ name: 'company', type: 'string' },
{ name: 'summary', type: 'string' },
{ name: 'address', type: 'string' },
{ name: 'industry', type: 'string' },
{ name: 'functionnml', type: 'string' },
{ name: 'role', type: 'string' }
],
proxy : {
type : 'ajax',
url : Proximity.util.Config.getBaseUrl() + '/index.php/recruiter/getrecruiterbest/',
withCredentials: false,
useDefaultXhrHeader: false,
reader : {
filters: [
Ext.create('Ext.util.Filter', {
property: 'ind_id',
property: 'fun_id',
property: 'role_id'
})
]
}
}
}
});
Look i have removed the code
extraParams: {
"id": localStorage.getItem('id')
},
from Model. And in my store i have added
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
},
So my new store code is as follows
Ext.define('Proximity.store.RecruiterbestStore', {
extend: 'Ext.data.Store',
alias: 'store.recruiterbeststore',
config: {
model: 'Proximity.model.RecruiterbestlistModel',
autoLoad: true,
remoteFilter: true,
storeId: 'recruiterbeststore'
},
listeners: {
beforeload: function(store){
this.getProxy().setExtraParams({
id: localStorage.getItem('id')
});
return true;
}
}
});
And its solved my problem.
But now i am having another issue. after running sencha app build native(using cordova bild), again i am having same issue, the extraParam are not added to proxy request.
Please help me to solve this.
I created a very simple model in Sencha Touch inside the model folder:
Ext.define('Vegetable',{
extend:'Ext.data.Model',
config:{
fields:
[
{name:'title', type:'string'}
]
}
});
When I try to refer to the model inside my Main.js file it says the model does not exist.
items: [
{
xtype:'list',
title:'Home',
iconCls:'home',
store:{
model:'**VegetableTreeSenchaTouch.model.Vegetable**',
proxy:{
type:'ajax',
url:'http://vegetablegardening.com/vegetable/catalog/23',
reader:{
type:'json',
}
},
autoLoad:true
}
}
]
}
UPDATED: app.js
views:['Main'],
stores:['Vegetables'],
models:['Vegetable'],
UPDATED: Vegetables (store)
Ext.define('VegetableTreeSenchaTouch.store.Vegetables',{
extends:'Ext.data.Store',
config:{
model:'VegetableTreeSenchaTouch.model.Vegetable',
data:[
{ title: 'Onion' },
{ title: 'Potato' }
]
}
});
Any ideas?
Define the proxy in your store:
Ext.define('VegetableTreeSenchaTouch.store.Vegetables', {
extend: 'Ext.data.Store',
config: {
model: 'VegetableTreeSenchaTouch.model.Vegetable',
proxy: {
type: 'ajax',
url: 'http://vegetablegardening.com/vegetable/catalog/23',
reader: {
type: 'json',
}
}
},
//...
});
and use an instance of the store:
{
xtype: 'list',
title: 'Home',
iconCls: 'home',
store: 'Vegetables'
}
Try naming your store and model with an extended name.
Ext.define('VegetableTreeSenchaTouch.model.Vegetable',{
extend:'Ext.data.Model',
and:
Ext.define('VegetableTreeSenchaTouch.store.Vegetables',{
extends:'Ext.data.Store',
config:{
model:'VegetableTreeSenchaTouch.model.Vegetable',
data:[
{ title: 'Onion' },
{ title: 'Potato' }
]
}
});
Not certain that this is the issue, but this is always how I name my models/stores to be sure they are referenced correctly.
Based on newly created Sencha Touch 2 app as it is learned here.
Then I'd like to add my nested list - hierarchical menu tree and found that doesn't matter - my store inline or my store read from json - nothing displayed inside tab 'Menu'.
What's wrong?

At what point your store is loaded? Shouldn't you use autoLoad:true in your store?
also if you don't want to create and load your store with application load you should manually create store whenever required and set it to list
var treeStore = Ext.create('MobilePost.store.MenuTree');
treeStore.load();
and use this as store attribute in your view
{
// Mine, not working
xtype: 'nestedlist',
title: 'Menu',
id: 'myListId',
iconCls: 'settings',
store: treeStore
}
OR set the store if view is already created
Ext.getCmp('myListId').setStore(treeStore);
I'm working on a basic Sencha Touch application that displays a list of text messages and the name of an associated user that sent the message. I have followed the tutorials online on how to setup model associations but each tutorial assumes that the server produces data with a nested structure.
The data I am working with has a flat structure with primary/foreign key relationships, and I cannot figure out how to get Sencha to load both stores from a single response.
model/User.js
Ext.define('App.model.User', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'uid', type: 'number' },
{ name: 'name', type: 'string' },
]
}
});
store/Users.js
Ext.define('App.store.Users', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.User',
autoLoad: true,
}
});
model/Message.js
Ext.define('App.model.Message', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'id', type: 'number' },
{ name: 'uid', type: 'number' },
{ name: 'message', type: 'string' }
],
associations: [{
type: 'belongsTo',
model: 'App.model.User',
primaryKey: 'uid',
foreignKey: 'uid'
}],
proxy: {
type: 'jsonp',
url: 'messages.json',
reader: {
type: 'json',
rootProperty: 'req_messages'
}
}
}
});
store/Messages.js
Ext.define('App.store.Messages', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.Message',
autoLoad: true,
}
});
The messages are correctly loaded and displayed by my application (sample JSON response below), but I cannot figure out how to get the associated users to be loaded into the store. Can this be solved with a configuration, or will I need a custom reader? Any help appreciated!
Sample JSON
{
"users": [{
"uid": "1",
"name": "John"
}, {
"uid": "3033",
"name": "Noah"
}],
"req_messages": [{
"id": "539",
"uid": "1",
"message": "my message"
}, {
"id": "538",
"uid": "1",
"message": "whoops"
}, {
"id": "534",
"uid": "3033",
"message": "I love pandas."
}]
}
I've never really worked with associations and I went through the document to try to find something that would load two stores with on request, but I couldn't find anything. So here's how I would do it :
Model
Ext.define('App.model.User', {
extend: 'Ext.data.Model',
config: {
fields: [
'uid',
'name'
]
}
});
Ext.define('App.model.Message', {
extend: 'Ext.data.Model',
config: {
fields: [
'id',
'message',
'uid'
],
associations: { type: 'hasOne', model: 'User', primaryKey: 'uid', foreignKey: 'uid'}
}
});
Stores
Ext.define('App.store.Users', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.User',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'http://www.titouanvanbelle.fr/test.json',
reader: {
type: 'json',
rootProperty: 'users'
}
},
listeners:{
load:function(s,r,success,op){
var msgs = JSON.parse(op.getResponse().responseText).req_messages;
Ext.each(msgs, function(msg) {
Ext.getStore('Messages').add(Ext.create('App.model.Message',msg));
});
}
}
}
});
Ext.define('App.store.Messages', {
extend: 'Ext.data.Store',
config: {
model: 'App.model.Message'
}
});
List
Ext.define("App.view.Main", {
extend: 'Ext.Panel',
config: {
fullscreen: true,
layout:'fit',
items: [{
xtype:'list',
store:'Messages',
itemTpl: new Ext.XTemplate(
'<tpl for=".">',
'{[this.getUserName(values)]} : {message}',
'</tpl>',
{
getUserName(v){
var s = Ext.getStore('Users'),
u = s.getAt(s.find('uid',v.uid));
return u.get('name');
}
}
)
}]
}
});
And you'd get something like this :
Hope this helps. If you need explanation, let me know.
I want to make a simple request like Ext.Ajax.request and display it in a list. But it does not work.
I have a URL like this
http://server/GetContacts.aspx?CustAccount=10019
Can someone tell me exactly how it works and what I should consider?
This is an example of what I get back.
{
"HasError": false,
"ErrorString": "",
"Data": [
{"ContactPersonId":"","Name":"","FirstName":"","MiddleName":"","LastName":"","Phone":"","CellularPhone":"","Telefax":"","Email":"","Url":"","Address":"","ZipCode":"","City":"","Street":"","Country":"","Function":""}
]
}
Ext.regModel('kunden', {
idProperty: 'id',
fields: [
{ name: 'ContactPersonId', type: 'string' },
.
.
.
{ name: 'Function', type: 'string' }
]
});
Ext.regStore('kundenStore', {
model: 'kunden',
sorters: [{
property: 'LastName'
}],
proxy: {
type: 'ajax',
url: 'http://server/GetContacts.aspx?CustAccount=10019'
},
reader: {
type: 'json',
root: 'Data'
}
});
NotesApp.views.kundenList = new Ext.List({
id: 'kundenList',
store: 'kundenStore',
grouped: true,
indexBar : true,
itemTpl: '<div class="list-item-title">{firstname} {lastname}</div>' +'<div class="list-item-narrative">{email}</div>',
listeners: {}
}
});
It can be so easily XP
