Question

I’m setting my fields directly in the store configuration.

Ext.define('T.store.Users', {
    extend: 'Ext.data.Store',

    autoLoad: false,

    fields: [
        { name: 'Id', type: 'int' },
        { name: 'Name', type: 'string' }
    ]
});

Is it possible to set somehow an idProperty for these fields direct in the store ? The only option I see is to create a separate model class containing a idProperty. But I’d like to avoid this.

You can theoretically change the idProperty from within the constructor this way:

Ext.define('T.store.Users', {
    extend: 'Ext.data.Store',

    autoLoad: false,

    constructor: function(){
        this.callParent(arguments);
        this.model.prototype.idProperty = 'Id';
    },

    fields: [
        { name: 'Id', type: 'int' },
        { name: 'Name', type: 'string' }
    ]
});
