CakePHP: how to use Controller::referer() in a view

I'm getting the following error:

Strict (2048): Non-static method Controller::referer() should not be called statically,
assuming $this from incompatible context [APP/View/Questions/admin_edit.ctp, line 20]

Caused by this: 

//in app/View/Questions/admin_edit.ctp
echo $this->Html->link('Cancel', Controller::referer() );

Why?

$referer_url = $this->referer('/', true); // you will get like (without base URL) "/users/profile"
$refererController = Router::parse($referer_url); // this will return $referer_url as array which contains 

Array ( 
   [controller] => users 
   [action] => profile 
}

if anyone face any error when you use Router::parse($referer_url) please add cakephp routing in your controller

use Cake\Routing\Router;

You don't. You use the request object instead:

$this->request->referer();

The controller does nothing else internally.

Careful: the referer can be empty and thus you might want to provide a fallback here in that case.

Also note the optional param $local:

@param boolean $local If true, restrict referring URLs to local server
