public function renderGallery() {
        $this->template->gallery = $this->model->getAllPhoto();
    }


public function uploadFileFormSucceeded(Form $form, $values)
    {
        /** @var \Nette\Http\FileUpload */
        $fileUpload = $form['subor']->getValue();
        $name = $fileUpload->getName();
        //$tmpName = $fileUpload->getTemporaryFile();
        $file = $fileUpload->getContents();
        $file = (string)$file;
        //bdump($tmpName);
        bdump($file);

        if ($fileUpload->isOk()) {
            $this->model->savePhoto($values,$name,$file);
        }
        bdump($fileUpload);
        $this->flashMessage('Práve ste pridali fotografiu do Vašej galérie.');
