addUpload a zachovanie hodnoty

vedel by si mi prosím pomôcť so zostavením tejto podmienky?

neviem totiž, čo mám porovnávať a čo k čomu priradiť.
(neviem, či addUpload obsahuje defaulte prázdnu hodnotu – aj po naplnení celého formuláru so setDefaults, či musím success funkcii priradiť parameter s cestami k súboru atď)

V modeli

public function saveBrewery($values)
{
    if (!$values['idbrewery'])
        $this->db->insert('?', $values)->into('brewery')->execute();
    else
        $this->db->update('brewery', $values)->where('idbrewery = ?', $values['idbrewery'])->execute();
}

V presenteri render

public function renderUpravPivovar($idexhibition, $idbrewery)
{
    //load single brewery
    if ($idbrewery) ($getBrewery = $this->vystavaManager->getBrewery($idexhibition, $idbrewery)) ? $this['upravitPivovarForm']->setDefaults($getBrewery) : $this->flashMessage('Žiadaná výstava neexistuje!');
    $this->template->breweryinfo = $this->vystavaManager->getBrewery($idexhibition, $idbrewery);
}

V presenteri component form

protected function createComponentUpravitPivovarForm()
{
    $exhibition = (int)$this->getParameter('idexhibition');
    //var_dump($this->context->parameters['wwwDir']); exit;

    $form = new Form;

    $form->addHidden('idbrewery');
    $form->addText('name', 'Názov pivovaru *')->setRequired();
    //$form->addText('imgBrewery', 'Obrázok pivovaru *')->setRequired();
    //$form->addText('imgBreweryteam', 'Obrázok tímu pivovaru *')->setRequired();
    $form->addUpload('imgBrewery', 'Obrázok pivovaru *')
        ->addCondition(Form::FILLED)
        ->addRule(Form::IMAGE, 'Vložte obrázok vo formáte JPEG/PNG/GIF')
        ->addRule(Form::MAX_FILE_SIZE, 'Maximálne veľkosť súboru je 300 kB.', 300 * 1024);
    $form->addUpload('imgBreweryteam', 'Obrázok tímu pivovaru *')
        ->addCondition(Form::FILLED)
        ->addRule(Form::IMAGE, 'Vložte obrázok vo formáte JPEG/PNG/GIF')
        ->addRule(Form::MAX_FILE_SIZE, 'Maximálne veľkosť súboru je 300 kB.', 300 * 1024);
    $form->addText('www', 'Webová stránka pivovaru');
    $form->addHidden('exhibition', $exhibition);
    $form->addInteger('breweryOrder', 'Poradie')
         ->setRequired()
         ->addRule(Form::RANGE, 'Poradie musí byť hodnota od 0 do 999', [0, 999]);
    $form->addSelect('enabled', 'Povoliť?', ['1' => 'Áno', '0' => 'Nie'])
         ->setDefaultValue('1');

    $form->addSubmit('submit', 'Uložiť');

    $form->onSuccess[] = [$this, 'upravitPivovarFormSucceeded'];
    return $form;
}

V presenteri succeed

public function upravitPivovarFormSucceeded($form, $values)
{
    $values = $form->getValues();
    $fileBrewery = $values->imgBrewery;
    $fileBreweryteam = $values->imgBreweryteam;

    if($fileBrewery->isImage() and $fileBrewery->isOk()) {
        $file_ext=strtolower(mb_substr($fileBrewery->getSanitizedName(), strrpos($fileBrewery->getSanitizedName(), ".")));
        $file_name = uniqid(rand(0,20), TRUE).$file_ext;
        $fileBrewery->move($this->context->parameters['wwwDir'] . '/img/pivovary/'. $file_name);
        $values->imgBrewery = 'img/pivovary/'. $file_name;
    }

    if($fileBreweryteam->isImage() and $fileBreweryteam->isOk()) {
        $file_ext=strtolower(mb_substr($fileBreweryteam->getSanitizedName(), strrpos($fileBreweryteam->getSanitizedName(), ".")));
        $file_name = uniqid(rand(0,20), TRUE).$file_ext;
        $fileBreweryteam->move($this->context->parameters['wwwDir'] . '/img/pivovary/'. $file_name);
        $values->imgBreweryteam = 'img/pivovary/'. $file_name;
    }

    try {
        $this->vystavaManager->saveBrewery($values);
        $this->flashMessage('Pivovar uložený.');
        $this->redirect('Vystava:uprav', $values->exhibition);
    } catch (UniqueConstraintViolationException $ex) {
        $this->flashMessage('Pivovar s týmto ID už existuje!');
    }
}

to mi ale tracy vyhodí chybu:
SQL translate error: Unexpected Nette\Http\FileUpload

UPDATE `brewery`
SET `idbrewery`='2', `name`=':) happy.', `imgBrewery`=**Unexpected Nette\Http\FileUpload**,
`imgBreweryteam`=**Unexpected Nette\Http\FileUpload**, `www`='', `exhibition`='2', `breweryOrder`=0,
`enabled`=1
WHERE idbrewery = '2'
