Как подключить базу данных к виджету ?

	class widgetTop extends cmsWidget {
 
		public function run (){
 
			return array();
 
		}
	}

$this->model->get('table_name');
или 
cmsCore::getModel('content')->get('table_name');

	public function addStreetballteam($streetball_team){		
		return $this->insert('streetball_teams', $streetball_teams);	
	}
	public function getStreetballteam($id){	
		return $this->getItemById('streetball_teams', $id);
	}
		public function getStreetballteams(){	
		return $this->get('streetball_teams');	
	}
	public function getStreetballteamsCount(){	
		return $this->getCount('streetball_teams');	
	}

		public function run(){
 
			$template = cmsTemplate::getInstance();
 
			$total = $this->model->getStreetballteamsCount();
 
			$streetball_teams = $this->model->orderBy('i.points','DESC')->getStreetballteams();
 
			$template->render('index', array(
				'teams' => $teams,
				'streetball_teams' => $streetball_teams,
				'total' => $total
			));
 
		}
