Как работать с двумя таблицами на одной странице в fat free framework ?

<?php
class Controller {
    protected $f3;
    protected $db;
    function beforeroute() {
    }

    function afterroute() {
		echo Template::instance()->render('client_layout.html');
    }

    function __construct() {

        $f3=Base::instance();

        $db=new DB\SQL(
            $f3->get('db_host') . $f3->get('db_name'),
            $f3->get('db_user'),
            $f3->get('db_pass')
        );

        $this->f3=$f3;
        $this->db=$db;
    }
}

class UserController extends Controller {
	public function index()
	{
		$this->f3->set('page_head','Главная странца');
		$this->f3->set('view','client/index.html');
	}
	
	public function breakage()
	{
		$breakage = new Breakage($this->db);
		$this->f3->set('breakage',$breakage->all());
		if($this->f3->exists('POST.create'))
		{
			$breakage = new Breakage($this->db);
			$breakage->datetime=date("Y-m-d H:i:s");
			$breakage->add();
			$this->f3->reroute('/breakage');
		} else
		{
		$this->f3->set('page_head','Список');
		$this->f3->set('view','client/breakage.html');
		}
	}
}

<?php
class Breakage extends DB\SQL\Mapper {
	
	public function __construct(DB\SQL $db)
	{
		parent::__construct($db,'breakage');
	}
	public function all()
	{
		$this->load();
		return $this->query;
	}
	public function add()
	{
		$this->copyFrom('POST');
		$this->save();
	}
	public function getById($id)
	{
		$this->load(array('id=?',$id));
		$this->copyTo('POST');
	}
}
