Localstorage access first()

[Kurt001]

Hi there,

I want to access the first item in a localstorage.

Here is my model:

Ext.define('AppData', {
    extend: 'Ext.data.Model',
    config: {
        identifier: 'uuid',
        proxy: { type: 'localstorage', id: 'appData' },
        fields: [{ 'id', 'name' }]
    }
});

Saving a record:

var myApp =Ext.create('AppData',{ name:'Ed Spencer' });
myApp.save({
        success:function(ed){
                console.log("Saved Ed! His ID is "+ ed.getId());
        }
});

The id is something like ext-record-1417

Here is how I want to load the first record:

var app = Ext.ModelMgr.getModel('AppData');
app.load(1, {
        success: function(app) {
                console.log("Loaded app 1: " + app.get('name'));
        },
        failure: function() {
                console.log("NOT loaded app 1");
        }
});

This always throws the failure.

I tried to use the example from the official example http://docs.sencha.com/touch/2-0/#!/guide/models.
But with the localstorage this does not work either.

Any idea?

Best

You could try something like this..

myStore.getData().items[0]

Hi ,

I do not have a store for the data.

I use this in my app with a Store too:

Store:

..
 config: {
        storeId: 'credentialsStore',
..

and then when I need the model

var credentials = Ext.getStore('credentialsStore').first();
credentials.get('name');

I use this in my app with a Store too:

Thanks but again: I do not want to use a store. This is a simple update function. The old version had a store, but only used a single record. Now I want to import the data from that first record.

I could create a store and destroy it right after the import, but I was wondering if there is a way without using a store.

what does first mean? you order by what?

model.load(id,config)

id != index

as you said

The id is something like ext-record-1417

so why you pass a count or index number?

[Kurt001]

what does first mean? you order by what?

Using a store I would receive this item with store.first().
Anyways as there is only one item in the localstorage for that model, I would just need that one.

so why you pass a count or index number?

What else would you pass?

[haduki]

pass the id

[george.m]

I'm guessing it's because that id changes every time he uses the app as it is one automatically generated by Sencha. Can you not add your own id to it?

@haduki
how do i find out the id?

I'm guessing it's because that id changes every time he uses the app as it is one automatically generated by Sencha. Can you not add your own id to it?

This is an update of the app. So the old app wrote the localstorage and now I want to load the localstorage in the model. If I write the id I would write a new record, which I could load afterwards.
But for now I do not know the id (auto-generated by Sencha).

so what I am doing for now is:

        Ext.define('oldData', {
            extend: 'Ext.data.Model',
            config: {
                identifier: 'uuid',
                fields: [
                    {name: 'id', type: 'int'},
                    {name: 'oneOfManyValues'}
                ],
                proxy: {
                    type: 'localstorage',
                    id: 'personalData'
                }
            }
        });
        var myStore = Ext.create('Ext.data.Store', {
            model: 'oldData',
            autoLoad: true
        });
        var oldData = myStore.first() ? myStore.first().getData() : null;
        Ext.StoreManager.remove(myStore);

This will do the trick, but I was hoping to go without the store.
