Phalcon PhP - how to change the view dynamically

I'm working in a website where part of it I have the static html, so I created a layout and in it I'm inserting the static content using views. My problem is as this website has many pages I feel wrong creating an action for each url. So I implemented the controller below:

class PageController extends ControllerBase

{

    public function initialize(){

        $this->init();

        $this->view->setLayout( 'website' );

    }



    public function indexAction ($url=''){

        if($url == 'about')

            $this->view->pick('page/about');

    }

}

When I set the controller view to render $this->view->pick('page/about'); it doesn't insert the view in the template. It renders only the view.

Is there a way to render the view within the layout, and is there a better approach to what I'm doing?

Thanks for any help
