class PostPresenter extends BasePresenter
{
    /** @var Nette\Database\Context */
    private $database;

    public function __construct(Nette\Database\Context $database)
    {
        $this->database = $database;
    }

    public function renderShow($postId)
    {
        $this->template->post = $this->database->table('blog_posts')->get($postId);
        $this->template->post = $post;
    	$this->template->comments = $post->related('comment')->order('date_comment');
    }

    public function createComponentCommentForm() {

    	$form = new Form;

    	$form->addText('name','Meno:')
    		 ->setRequired();

    	$form->addTextArea('content', 'Komentár:')
        ->setRequired();

        $form->addSubmit('send', 'Publikuj');
     	$form->onSuccess[] = array($this, 'commentFormSucceeded');
    	return $form;
    }

    public function commentFormSucceeded($form, $values) {
    	$postId = $this->getParameter('postId');
    	$this->database->table('comments')->insert(array(
    		'post_id' => $postId,
    		'name' => $values->name,
    		'text' => $values->text,
    		));
    	$this->flashMessage('Ďakujem za komentár', 'success');
    	$this->redirect('this');
    }
}

a tu je šablona

  {foreach $comments as $comment}
        <p><b>{$comment->name}</b> napisal:</p>
        <div>{$comment->content}</div>
    {/foreach}
