Vich Uploader 和 Symfony 验证的问题

Question

我有这个表格，附有 oneToMany 文档的报告

class ReportType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('documentDatas', CollectionType::class, array(
                'entry_type' => DocumentType::class,
                'allow_add' => true,
                'allow_delete' => true,
                'label' => false
            ))
            ->add('comment', TextType::class, array(
            'label' => 'vat',
            'required' => false,
             ))
            ->add('save', SubmitType::class);
    }
}

这是文档类型

class DocumentType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('examDocument', VichImageType::class, array(
                'label' => 'examDocument',
                'data_class' => null,
                'attr' => array('class' => 'upload-image'),
            ))
            ->add('note', TextType::class, array(
                'label' => 'notes',
                'required' => false,
            ));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Model\DocumentData',
        ));
    }
}

我使用 VichImageType 上传的地方。当表单验证正常时，一切正常，文件被上传，文档实体添加到我的数据库中。 但是当某些验证被违反时（在文档或评论上）我收到这个奇怪的错误：

“AppBundle\Model\DocumentData”类不可上传。如果你使用 配置 VichUploaderBundle 的注释，你可能只是忘记了 在您的实体顶部添加@Vich\Uploadable。如果你不使用 注解，检查配置文件是否正确 地方。在这两种情况下，清除缓存也可以解决问题。

当我的操作尝试响应视图时，当表单无效时，我会收到此消息：

public function commentAction(Request $request) {
        $reportData = new ReportData();

    $form = $this->createForm(ReportType::class, $reportData);

    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()){

        //some logic
    }

    return $this->render('report/form.html.twig', [
        'form' => $form->createView(),  //symfony evidence this row in the exception
    ]);
}

Answer 1

我解决了在我的数据模型中添加 Vich Uploadable 注释映射，如下所示：

/**  * @Vich\Uploadable  */ class DocumentData {
    /**
     * @Assert\NotNull()
     * @Assert\File(
     *     maxSize = "5M",
     *     mimeTypes = {"image/*", "application/pdf"}
     * )
     * @Vich\UploadableField(mapping="document_file", fileNameProperty="examDocument")
     */
    public $examDocument;

    /**
     * @Assert\Length(
     *      min = 2,
     *      max = 30,
     * )
     */
    public $note;

    public function getExamDocument()
    {
        return $this->examDocument;
    }

    public function setExamDocument($examDocument)
    {
        $this->examDocument = $examDocument;
    }

    public static function create(Document $document)
    {
        $edm = new static();
        $edm->examDocument = $document->getExamDocument();
        $edm->note = $document->getNote();

        return $edm;
    } }
