我正在尝试使用 Vich 将上传链接到 Sonata Admin 中的实体。

所有的配置都完成了,但是文件没有上传,我找不到错误。

问题是当您尝试上传文件时,一切似乎都正常,Sonata 将所有数据库字段中的数据持久化,并将文件上传到系统中的 /tmp 文件夹,此外,sonata 打印 tmp 路由在数据库的补丁字段中。但该文件永远不会到达在 gaufrette 中设置的文件夹,也不会生成唯一名称。

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,具有非持久字段和路径字段,女巫是我要存储文件路径的位置:

/**
     * 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 vich 和 gaufrette 配置:

vich_uploader:
    db_driver: orm
    storage:   gaufrette

    mappings:
        question_image:
            uri_prefix:         ~ 
            upload_destination: questions_image_fs
            namer:              vich_uploader.namer_uniqid
        download_file:
            uri_prefix:         ~
            upload_destination: download_file_fs
            namer:              vich_uploader.namer_uniqid

knp_gaufrette:
    stream_wrapper: ~

    adapters:
        questions_image_adapter:
            local:
                directory: %kernel.root_dir%/../web/images/questions
        download_file_adapter:
            local:
                directory: %kernel.root_dir%/../web/files/download

    filesystems:
        questions_image_fs:
            adapter:    questions_image_adapter
        download_file_fs:
            adapter:    download_file_adapter

VichUploaderBundle 依赖于 Pre persist/update 等 Doctrine 事件来触发其上传功能。当您在管理部分打开现有实体并上传新文件而不更改任何其他内容时,原则不会调度生命周期事件,因为没有更改任何特定于原则的字段。

因此,每当将新文件对象传递给实体时,您都需要更新一些特定于教义的字段值,例如updatedAt. 将实体修改setDownloadFile为:

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

    if ($file) {
        $this->updatedAt = new \DateTimeImmutable();
    }

    return $this;
}

此外,您还需要添加updatedAt字段并且它是映射以防万一。

查看 VichUploaderBundle 文档页面上的示例:https ://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md#step-2-link-the-upload-mapping-to-an -实体

更新

您还需要在downloadFile属性上定义表单字段而不是path
