Vich and gaufrette are not saving files in sonata admin - php

Question

I'm trying to make an upload linked to an entity in Sonata Admin using Vich.
All the configuration is done but the file does not upload, and I cannot find the error.
The problem is that when y try to upload the file, every thing seem to work fine, Sonata persists the data in all the data base fields, and the file is uploaded to /tmp folder in teh sistem,also, sonata prints the tmp route in the patch field in database. But the file never gets to the folder setted in gaufrette and neither generates the unique name.
Here is the code:
The admin Class:
<?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(),
)
))
;
}
}
Here is the entity, with the not persistent fieln and the path field, witch is wher eI want tostore the file path:
/**
* 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;
}
The services 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" }
and 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" }
And last vich and gaufrette configuration:
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 relies on Doctrine Events like pre persist/update to trgger its upload functionality. When you open existing entity in the admin section and upload new file without changing anything else, doctrine wouldn't dispatch lifecycle events as none of doctrine specific fields are changed.
So whenever new file object passed to the entity you need to update some doctrine specific field value, like updatedAt. Modify setDownloadFile of the entity to:
/**
* #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;
}
Also you need to add updatedAt field and it's mapping in case you didnt.
Take a look at the example on VichUploaderBundle documentation page: https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md#step-2-link-the-upload-mapping-to-an-entity
UPDATE
Also you need to define form field on downloadFile property instead of path
