Is there any way to disable “idProperty” of Model in Extjs?

Question

I have a simple Model/proxy. When I create a object of model to send to server via REST, ExtJs is generating Id and putting its value in my \"id\" field and that is conflicting

Answer 1

Set config options: persist: false.

Ext.define('User', {
    extend: 'Ext.data.Model',
    idProperty : 'login'
    fields: [
        {name: 'login', type: 'string', persist: false},
        {name: 'username', type: 'string'},
        {name: 'password', type: 'string'}
    ]
});
