View Full Version : localstorage empty after browser refresh

17 May 2012, 5:24 AM
i am using a store with a localstorage proxy which i configured like below.

Ext.define('VB1.store.FavoritesStore', {
extend: 'Ext.data.Store',
alias: 'widget.favoritesstore',
config: {
storeId: 'vbFavoritesStore'',
model: 'VB1.model.myModel',
autoLoad: false,
proxy: {
type: 'localstorage',
id: 'favprodproxy'

adding items to the store and view the is no problem, however, when i refresh the browser (chrome) the store is empty again. Is there anything i overlook? thanks a lot for any suggestions

Do you load the store?

no. i noticed previously that when i do this the store gets emptied even without page refresh.

no. i tried that before but that seems to empty the store even without page refresh. in the chrome console under resources i can see that there is a local storage object named after the proxys id (which is still there after page refresh). however this object seems to have no value. hence the store has data (since i can display it), the localstorage object in the console is empty however before and after the page refresh.

ST 2.0.0 or 2.0.1?

I always use
autoLoad: true,
autoSync: true,

which works fine.

I think you will not get an answer or solution here if you won´t post your full source or a simplified example.

I done it, how write above. Also, be sure to register types of data fields, without this will not work! ;)

It will work :

put below lines in your store -

autoLoad: true,
autoSync: true,

Make sure you let the store manage id generation of your objects. I had this bug and resolved it by letting the store manage the ids.

fields: ['id', 'nid', 'thumb', 'title', 'surface', 'chambres', 'secteur', 'prix']

nid is my own id and i added the id field.

Hope it help.

I also had problems with this when I started to use it a few weeks ago. Since I was (and I am still) in a steep learning curve, I am not sure that my problem was same. Anyway I was able to solve my issue:
I found this release note for Sencha Touch 2
If you are using a LocalStorage proxy, from now on your Model's identifier strategy must generate unique id's. We suggest you use the included UUID strategy by adding identifier: 'uuid' to your Model definition. Any existing Models you have saved to LocalStorage will need to have this added. A warning will be thrown for any Model configured with a LocalStorage proxy that doesn't have a unique id generating strategy.
So I added in the model "identifier: 'uuid". This solved my problem.
Maybe it is worth a try...

thanks everybody for the suggestions. i tried them all, however, although i can store data in the localstore once i reload he page the store is empty again:

here is my code

the store:

Ext.define('VB1.store.prod.FavProdStore', {
extend: 'Ext.data.Store',
alias: 'widget.favprodstore',
config: {
storeId: 'vbFavProdStore',
model: 'VB1.model.prod.FavProdModel',
autoLoad: true,
autoSync: true,
proxy: {
type: 'localstorage',
id: 'favprodproxy'

my model:

Ext.define('VB1.model.prod.FavProdModel', {
extend: 'Ext.data.Model',
config: {
identifier: 'uuid',
fields: [
{name: 'id'},
{name: 'mid', type: 'string'},
{name: 'shop_id', type: 'string'},
{name: 'title', type: 'string'},
{name: 'lat', type: 'float'},
{name: 'lng', type: 'float'},
{name: 'distance', type: 'float'},

this is how i dd items to the store

addFavorite: function () {
var prodDetails = this.getProdDetailView().getData(),
favData = this.favprodstore.findRecord('mid',prodDetails.mid);
if (!favData) {
var dataCount = this.favprodstore.getCount();
} else {

is anyone spotting what is wrong here?

i solved it. thanks for all the suggestions. it had to to with how other models that i was using were configured. basically the problem was that no unique identifier strategy was applied

I solved the problem adding the idProperty: 'id' to my store, this line say to the browser a way to find the data that we save ^^ you dont need have a id field this value is generated automatically ('i think so', you can see this into console>resources>localstorage (chrome))
