未找到Symfony2实体-在关系中上传文件 - Symfony2 Entity was not found - FIle Upload in a relationship

Symfony2 Entity was not found - FIle Upload in a relationship

本文关键字：关系文件 Symfony2 实体 | 更新日期: 2023-09-27

我有一个实体，它有一个带有文件实体的ManyToOne。

我的问题是当我试图删除。

我是这样创建的:

/**
 * Creates a new Catalogo entity.
 *
 * @Route("/create", name="catalogo_create")
 * @Method("POST")
 * @Template("BWSBajaCupcakesBundle:Catalogo:new.html.twig")
 */
public function createAction(Request $request)
{
    $entity  = new Catalogo();
    $file = new Archivo();
    $form = $this->createForm(new CatalogoType(), $entity);
    $form->bind($request);
    $file_form = false;
    if($form['file']->getData()){
        $file_form = $form['file'];
        //unset($form['file']);
    }
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($entity);
        if($file_form){
                $tipoImagen = $em->getRepository('BWSBajaCupcakesBundle:TipoArchivo')->find(1);
                $file->setFile($file_form->getData());
                $file->setPrincipal(true);
                $file->setTipo($tipoImagen);
                $file->setFechaCaptura(date_create(date("Y-m-d H:i:s")));
                $file->upload();   
                $em->persist($file);
                $entity->setImagen($file);
        }
        $em->flush();
        return $this->redirect($this->generateUrl('catalogo_show', array('id' => $entity->getId())));
    }
    return array(
        'entity' => $entity,
        'form'   => $form->createView(),
    );
}

我是这样删除的:

/**
     * Deletes a Catalogo entity.
     *
     * @Route("/{id}/delete", name="catalogo_delete")
     * @Method("POST")
     */
    public function deleteAction(Request $request, $id)
    {   
        $form = $this->createDeleteForm($id);
        $form->bind($request);
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $entity = $em->getRepository('BWSBajaCupcakesBundle:Catalogo')->find($id);
        if (!$entity) {
            throw $this->createNotFoundException('Unable to find Catalogo entity.');
        }
        $em->remove($entity);
        $em->flush();
    }
    return $this->redirect($this->generateUrl('catalogo'));
}

这是我的关系:

/**
 * @ORM'ManyToOne(targetEntity="BWS'BajaCupcakesBundle'Entity'Archivo", cascade={"all"})
 * @ORM'JoinColumn(name="imagen_id", referencedColumnName="id")
 */
private $imagen;

我不明白，我在我的其他Symfony应用程序中也这样做过，从来没有遇到过这个问题。

提前感谢您的帮助。

欢呼

虽然您在评论中有答案，但我认为我将在任何情况下(基于cookbook文档实体)给出代码:

/**
 * Pre remove upload
 *
 * @ORM'PreRemove()
 */
public function preRemoveUpload()
{
    $this->temp = $this->getAbsolutePath();
}
/**
 * Remove upload
 *
 * @ORM'PostRemove()
 */
public function removeUpload()
{
    if ($this->temp) {
        unlink($this->temp);
    }
}
