Change user last logon time upon login

[ewvic]

Hello, I'm new to CakePHP. I tried searching for "user last logon" or
"last access" in this group, but I don't see any relevant post.
Apologies if I didn't read carefully enough!

Question: What's the easiest way to change a field such as "lastlogon"
in a user table upon user login? (I thought imitating what edit() is
doing would be enough, but...)

I'm following the example of Simple User Authentication:
http://manual.cakephp.org/chapter/19

Here are some snippets:

class AppController extends Controller
{
...
   function checkLogin()
    {
        // If the session info hasn't been set...
        if (!$this->Session->check('User'))
        {
            // Force the user to login
            $this->redirect('/users/login');
        }
    }
}

class UsersController extends AppController
{
    var $name = 'Users';
    var $uses = 'User';
...
        function index()
        {
                $this->checkLogin(); // force login

                // user can only read their own record
                $this->set('data', array('User' => 
$this->Session->read('User')));
        }

        function login()
    {
        // If has submitted form data:
        if (!empty($this->data))
        {

            $someone =
$this->User->findByUsername($this->params['data']['User']['username']);

            if($someone['User']['password'] ==
md5($this->params['data']['User']['password']))
            {

                $this->Session->write('User', $someone['User']);
                                $this->set('login_error', false);

                                // change lastlogon value and ip information
                                /*
                                $someone['User']['lastlogon'] = date("Y-m-d 
G:i:s");
                                $this->User->save($someone);
                                */
                                $this->User->saveField('lastlogon', date("Y-m-d 
G:i:s"));
       // neither save() or saveField() in the above block works

                $this->redirect('/users');
            }
            else
            {
                $this->set('login_error', true);
            }
        }
                else
                {
                        $this->set('login_error', false);
                }
    }
}

Field "lastlogon" is of type "datetime".

I'm sure this problem is really easy to solve. I just need some idea as
to why this code won't work. Any gotchas in my syntax?

Thank you for your time!
