>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,但文件未上传,我找不到错误。
问题是,当y尝试上传文件时,一切似乎都工作正常,Sonata将数据保留在所有数据库字段中,并将文件上传到系统中的/tmp文件夹,此外,Sonata在数据库的补丁字段中打印tmp路由。但是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 DownloadFileAdminBundleAdmin;
use SonataAdminBundleAdminAbstractAdmin;
use SonataAdminBundleAdminAdmin;
use SonataAdminBundleDatagridDatagridMapper;
use SonataAdminBundleDatagridListMapper;
use SonataAdminBundleFormFormMapper;
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', 'DownloadFileAdminBundleFormExtensionVichFileObjectType', $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,带有非持久性 fieln 和路径字段,女巫是我想存储文件路径的:
/**
* NOTE: This is not a mapped field of entity metadata, just a simple property.
* @VichUploadableField(mapping="download_file", fileNameProperty="path")
* @var File
*/
private $downloadFile;
/**
* @ORMColumn(type="string")
*/
protected $path;
public function getDownloadFile()
{
return $this->downloadFile;
}
/**
* @param File|SymfonyComponentHttpFoundationFileUploadedFile $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: DownloadFileAdminBundleAdminDownloadFileAdmin
arguments: [~, OposDownloadFileBundleEntityDownloadFile, 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: DownloadFileAdminBundleFormExtensionVichFileObjectType
arguments: [ "@doctrine.orm.entity_manager" ]
tags:
- { name: "form.type", alias: "vich_file_object" }
最后的 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 Doctrine 事件(如预持久/更新)来扩展其上传功能。当您在管理部分中打开现有实体并上传新文件而不更改任何其他内容时,doctrine 不会调度生命周期事件,因为不会更改任何特定于 doctrine 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学说的字段值,例如updatedAt
。将实体的setDownloadFile
修改为:
/**
* @param File|SymfonyComponentHttpFoundationFileUploadedFile $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,以防万一您没有
看看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-entity
更新
此外,您还需要在downloadFile
属性上定义表单字段,而不是path
