retrieving user information from auth component

I have problems checking 开发者_JS百科if user is logged in from any controller other than UsersController.

I was trying to make a user profile page. I routed it to PagesController and when I use

$this->Auth->user()

it always returns null. But if I route it to UsersController it works fine. Why is that? Login seems to work ok.

Your app_controller.php :

class AppController extends Controller {

    var $components = array('Auth', 'Session', 'Cookie');

    function beforeFilter() {
        $this->Auth->authError = 'blabla';
        $this->Auth->loginError = 'blabla';
    }

}

In your controllers :

function beforeFilter() {
    parent::beforeFilter();
    $this->Auth->allow('function1', 'function2', 'function3'); //etc
    $this->Auth->autoRedirect = true;
}

It's because you include the Auth component only in your User's controller. You should include it in AppController and in beforeFilter(). This way you will have access in all controllers.
