How to have multiple Stores implement the same model and load it correctly?

[Saurav.Mittal]

Hi Guys,

I ran into a trivial issue, in my app, I want to have a question bank with a set of Q&A for each specific subjects and want to have an individual Store for each subject. As all the question bank fields would be same, i would like to have a single Model and have all Stores follow that model. How can this be achieved or the best way to do it?

Now, the weird problem is when i implement - When i assign the store to the List, the store which is mentioned last in the declaration (app.js) shows up in data irrespective of the Store I load.

app.js
stores: ["Java","C","DBMS"],

My view:
xtype: "list",
            store: Ext.getStore("C"),
            itemTpl: '{id}. {q}',

Even though i pass C store, the q field from DBMS store gets loaded in the view but id (the question number) is equal to the no. of questions/records in C store, not DBMS store. My model and Store defs.

Model:
---------
Ext.define("IApp.model.Questions", {
    extend: "Ext.data.Model",
    config: {
        idProperty: 'id',
        fields: [
            { name: 'id', type: 'int' },
            { name: 'q', type: 'string' },
            { name: 'a', type: 'string' }
        ]
    }
});
---------------------------------------------------------------------
Stores:
--------
Ext.define("IApp.store.C", {
    extend: "Ext.data.Store",
    config: {
        model: "IApp.model.Questions",
        data: [
        {id:1, q:'This is 1st question for C language', a:'This is 1st answer for C language'},
------------------------------------------------------------------------------------------
Ext.define("IApp.store.DBMS", {
    extend: "Ext.data.Store",
    config: {
        model: "IApp.model.Questions",
        data: [
           {id:1, q:'This is 1st question for Database', a:'This is 1st answer for Database'},

If you change the name of your id field from id to something else (e.g. uid) I imagine your problem will be fixed.

Thanks a lot! It worked, and after looking at idProperty of the Model class, I understood the reason too.

Thank you once again!
