Vich和gaufrette没有在sonata admin中保存文件

我正在尝试使用Vich将上传链接到Sonata Admin中的实体 .

所有配置都已完成，但文件没有上传，我找不到错误 .

问题是，当你尝试上传文件时，每件事似乎都能正常工作，Sonata会在所有数据库字段中保存数据，并且文件会上传到teh sistem中的/ tmp文件夹，而且，sonata打印tmp路由在数据库中的补丁字段中 . 但文件永远不会到达gaufrette中设置的文件夹，也不会生成唯一的名称 .

这是代码：

管理员类：

<?php

namespace DownloadFileAdminBundle\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Form\FormMapper;

class DownloadFileAdmin extends Admin
{
    const FILE_MAX_SIZE = 2 * 1024 * 1024; // 2 megas

    /**
     * @param FormMapper $formMapper
     */
    protected function configureFormFields(FormMapper $formMapper)
    {
        $fileOptions = array(
            'label' => 'Archivo',
            'required' => true,
            'vich_file_object' => 'downloadfile',
            'vich_file_property' => 'downloadFile',
            'vich_allow_delete' => true,
            'attr' => array(
                'data-max-size' => self::FILE_MAX_SIZE,
                'data-max-size-error' => 'El tamaño del archivo no puede ser mayor de 2 megas'
            )
        );

        $formMapper
            ->add('slug', null, array('label' => 'Slug'))
            ->add('title', null, array('label' => 'Título'))
            ->add('description', null, array('label' => 'Descripción'))
            ->add('roles')
            ->add('path', 'DownloadFileAdminBundle\Form\Extension\VichFileObjectType', $fileOptions)
        ;

    }

    /**
     * @param ListMapper $listMapper
     */
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->add('id')
            ->add('slug')
            ->add('title')
            ->add('description')
            ->add('path')
            ->add('roles')
            ->add('_action', null, array(
                'actions' => array(
                    'show' => array(),
                    'edit' => array(),
                    'delete' => array(),
                )
            ))
        ;
    }

}

这是实体，具有非持久性fieln和路径字段，女巫是我想要存储文件路径：

/**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     * @Vich\UploadableField(mapping="download_file", fileNameProperty="path")
     * @var File
     */
    private $downloadFile;

    /**
     * @ORM\Column(type="string")
     */
    protected $path;

    public function getDownloadFile()
    {
        return $this->downloadFile;
    }

    /**
     * @param File|\Symfony\Component\HttpFoundation\File\UploadedFile $file
     *
     * @return File
     */
    public function setDownloadFile(File $file = null)
    {
        $this->downloadFile = $file;
        return $this;
    }

    /**
     * @return mixed
     */
    public function getPath()
    {
        return $this->path;
    }

    /**
     * @param mixed $path
     */
    public function setPath($path)
    {
        $this->path = $path;
    }

服务os admin.yml

services:
    sonata.admin.file:
        class: DownloadFileAdminBundle\Admin\DownloadFileAdmin
        arguments: [~, Opos\DownloadFileBundle\Entity\DownloadFile, SonataAdminBundle:CRUD]
        tags:
            - { name: sonata.admin, manager_type: orm, group: "Files", label: "Archivo" }

和services.yml：

services:
    download_file_admin_bundle.vich_file_object_type:
        class: DownloadFileAdminBundle\Form\Extension\VichFileObjectType
        arguments: [ "@doctrine.orm.entity_manager" ]
        tags:
            - { name: "form.type", alias: "vich_file_object" }

最后的vich和gaufrette配置：
