Uncaught TypeError: Object [object Object] has no method 'validate'

Unfortunately I couldn't create a working example with your tutorial because Ember.Object.extend does not work, is it outdated?

So I have the following:

App.User = DS.Model.extend(Ember.Validations, {
    validations: {
        firstname: {
            presence: true
        }
   }
}

My Controller which handles the user object which is created by user input (form elements):

App.IndexController = Ember.Controller.extend({
    actions: {
        register: function(){
            var user = this.get('model');
            user.validate();
       }
    }
});

At that moment I get the error: Uncaught TypeError: Object [object Object] has no method 'validate' What have I done wrong? Bug? Thx for help.

For your information, why Ember.Object.extend does not work, I get the following error then:

Assertion failed: Expected hash or Mixin instance, got [object Undefined] ember.js:394
