Redirect to dashboard by user's group

I have acl based CakePHP app and users are belong to groups.

Please开发者_如何学C advice me where I should implement the redirection code by user's group:

• users belong to admin group redirect to admin/dashboard
• users belong to manager group redirect to manager/dashboard
• users belong to user group redirect to user/dashboard

set $this->Auth->autoRedirect = false; in beforeRedirect() in users controller

In the login() function:

if ($this->Auth->user()){
$this->redirect(array('prefix'=>$this->Auth->user('group'),'controller'=>'dashboard','action'=>'index'));
 }

This code is just example to show how it is done, not to be taken as-is.
