Question

我在Symfony中尝试编辑记录。我可以编辑文本记录但是我无法在记录中编辑新文件。（（文件保存在存储中但不保存在数据库上））

我如何使用VichUploaderBundle 1.4在Symfony 3.4中做到这一点...... 对于插入，我没有任何问题我将图像上传到存储并保存在数据库中 .....

这是我的editAction

/**
 * @Route("/Article/editArticle/{id}",name="editArticle")
 */
public function editArticleAction(Request $request, $id)
{
    $em = $this->getDoctrine()->getManager();
    $articleRepo=$em->getRepository('AdminBundle:Article');
    $articleata = $articleRepo->find($id);
    // $satelliteImage=new satelliteImage;
    $article = new Article();
    $form = $this->createForm(ArticleType::class,$article,array(
        'action' => $this->generateUrl('editArticle',array('id' => $articleata->getId())),
        'attr' => array(
            'class' => 'dropzone',
            'id'  => "my-awesome-dropzone"
        ),
        'method' => 'POST',
        [
            'name'        => $articleata->getName(),
            'title'       => $articleata->getTitle(),
            'subject'     => $articleata->getSubject(),
            'description' => $articleata->getDescription(),
            'smallPic'    => $articleata->getSmallPic(),
            'largPic'     => $articleata->getLargPic(),
            'displayStatus' => $articleata->getDisplayStatus()]
    ));
   //

    if ($request->getMethod() == Request::METHOD_POST){
 $form->handleRequest($request);
        $article->setName($form->get('name')->getData());
        $article->setTitle($form->get('title')->getData());
        $article->setSubject($form->get('subject')->getData());
        $article->setDescription($form->get('description')->getData());
        $article->setDisplayStatus($form->get('displayStatus')->getData());
        $article->setSmallPic($form->get('imageFile')->getData());
        $article->setLargPic($form->get('imageFile2')->getData());
        $em = $this->getDoctrine()->getManager();

        $em->flush();
    }
    return $this->render('AdminBundle:Article:edit_article.html.twig', array(
        'form' => $form->createView(),
        'Articles' => $articleata


    ));
}

在冲洗之前，你需要：

$em->persist($article);

更新：

通常，VichUploader Bundle不再被视为上传图像的最佳做法。在DB中存储图像数据确实会增加它的大小，并且不建议这样做。你有另一个名为media的实体，有一些字段，如hash，path，size等...你应该使用文件系统，如果你想改变，可以使用抽象，例如，未来的亚马逊S3或谷歌存储。

查看使用flysystem bundle的令人敬畏的flysystem library。

尝试编辑symfony中的记录（文件VichUploaderBundle）
