Как вывести данные из разных таблиц?

 
turnir.php
<?php
class actionTournamentEvent extends cmsAction {
	public function run($id = false){	
		if (!$id) { cmsCore::error404(); }			
		$tournaments = $this->model->getTournaments($id);
		$teams = $this->model->getTournamen();
 
		if (!$tournaments ) { cmsCore::error404(); }
		$template = cmsTemplate::getInstance();
 
		$template->render('event', array(
			'tournaments' 	=> $tournaments,
			'teams' 		=> $teams,
			'fields'        => $fields
	));
 
	}	
}
 

 
public function addTournament($tournament){		
		return $this->insert('tournaments', $tournaments);	
	}
	public function getTournament($id){	
		return $this->getItemById('tournaments', $id);
	}
		public function getTournaments(){	
		return $this->get('tournaments');	
	}
	public function getTournamentsCount(){	
		return $this->getCount('tournaments');	
	}
		public function getTournamen($id, $tournament_id){	
		return $this->get('streetball', 'tournaments', $id, $tournament_id);	
	}
