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

I ran into same problem and using ajokn answer I did this.

Ext.define('ThemeApp.model.peopleModel', {
    extend: 'Ext.data.Model',

    fields: [ 
        {name: 'id', type: 'int', persist: false},
        {name: 'xyz', type: 'auto'}
    ]
}

I didn't set the idProperty : 'login' cause its default value is 'id', so simply set persist: false for id property in your model.

Answer 2

Set the idProperty to a non existing field. Its dirty I know, but this should do it.

Ext.define('User', {
    extend: 'Ext.data.Model',
    idProperty : 'foo'
});

Answer 3

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'}
    ]
});
