Symfony2: Overriding createAction() in SonataAdmin - php

Question

I've been googling as crazy the last days trying to figure out (with no success) how override a SonataAdmin action to capture the session username and save it in the foreign key field.
AttachmentAdminController class:
<?php
namespace Application\Sonata\UserBundle\Controller;
use Sonata\AdminBundle\Controller\CRUDController as Controller;
#use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use FOS\UserBundle\Entity\User;
use Symfony\Component\Security\Core\SecurityContextInterface;
use Symfony\Bridge\Monolog\Logger;
use Mercury\CargoRecognitionBundle\Entity\Attachment;
class AttachmentAdminController extends Controller
{
/**
* (non-PHPdoc)
* #see Sonata\AdminBundle\Controller.CRUDController::createAction()
*/
public function createAction()
{
$result = parent::createAction();
if ($this->get('request')->getMethod() == 'POST')
{
$flash = $this->get('session')->getFlash('sonata_flash_success');
if (!empty($flash) && $flash == 'flash_create_success')
{
#$userManager = $this->container->get('fos_user.user_manager');
#$user = $this->container->get('context.user');
#$userManager = $session->get('username');
$user = $this->container->get('security.context')->getToken()->getUser()->getUsername();
$attachment = new Attachment();
$attachment->setPath('/tmp/image.jpg');
$attachment->setNotes('nothing interesting to say');
$attachment->getSystemUser($user);
$em = $this->getDoctrine()->getEntityManager();
$em->persist($product);
$em->flush();
}
}
return $result;
}
}
service attachment:
mercury.cargo_recognition.admin.attachment:
class: Mercury\CargoRecognitionBundle\Admin\AttachmentAdmin
tags:
- { name: sonata.admin, manager_type: orm, group: General, label: Attachments }
arguments: [ null, Mercury\CargoRecognitionBundle\Entity\Attachment, "SonataAdminBundle:CRUD" ]
Seems to me as the actionController() is been ignored by SonataAdminBundle (and maybe the whole class file), because there's not error messages at all, but I don't know why. Actually, I'm not sure if I'm fetching the username from the session.
I really need a good tutorial about this, but seems like any information I get about this is obsolete in some aspect. By the way, I'm using Symfony 2.0.16

Finally I got to the solution. I'm sure there are some others (like using event listeners, for example, that seems to be simpler), but right now it's the best I could find (it works, and that's what matters).
I was trying to override the createAction() based on examples that I found in another forum thread, but I was getting two records in the table instead of one only. The most important thing was overriding the WHOLE action method and put the custom code in it.
Controller:
<?php
namespace Mercury\CargoRecognitionBundle\Controller;
use Symfony\Component\Security\Core\SecurityContextInterface;
use Symfony\Bridge\Monolog\Logger;
use Sonata\AdminBundle\Controller\CRUDController as Controller;
use Application\Sonata\UserBundle\Entity\User;
use Mercury\CargoRecognitionBundle\Entity\Attachment;
use Mercury\CargoRecognitionBundle\Entity\SystemUser;
use Mercury\CargoRecognitionBundle\Repository\SystemUserRepository;
class AttachmentAdminController extends Controller
{
/**
* Set the system user ID
*/
private function updateFields($object)
{
$userName = $this->container->get('security.context')
->getToken()
->getUser()
->getUsername();
$user = $this->getDoctrine()
->getRepository('ApplicationSonataUserBundle:User')
->findOneByUsername($userName);
$object->setSystemUser($user);
return $object;
}
/**
* (non-PHPdoc)
* #see Sonata\AdminBundle\Controller.CRUDController::createAction()
*/
public function createAction()
{
// the key used to lookup the template
$templateKey = 'edit';
if (false === $this->admin->isGranted('CREATE')) {
throw new AccessDeniedException();
}
$object = $this->admin->getNewInstance();
$object = $this->updateFields($object);
// custom method
$this->admin->setSubject($object);
$form = $this->admin->getForm();
$form->setData($object);
if ($this->get('request')->getMethod() == 'POST') {
$form->bindRequest($this->get('request'));
$isFormValid = $form->isValid();
// persist if the form was valid and if in preview mode the preview was approved
if ($isFormValid && (!$this->isInPreviewMode() || $this->isPreviewApproved())) {
$this->admin->create($object);
if ($this->isXmlHttpRequest()) {
return $this->renderJson(array(
'result' => 'ok',
'objectId' => $this->admin->getNormalizedIdentifier($object)
));
}
$this->get('session')->setFlash('sonata_flash_success','flash_create_success');
// redirect to edit mode
return $this->redirectTo($object);
}
// show an error message if the form failed validation
if (!$isFormValid) {
$this->get('session')->setFlash('sonata_flash_error', 'flash_create_error');
} elseif ($this->isPreviewRequested()) {
// pick the preview template if the form was valid and preview was requested
$templateKey = 'preview';
}
}
$view = $form->createView();
// set the theme for the current Admin Form
$this->get('twig')->getExtension('form')->setTheme($view, $this->admin->getFormTheme());
return $this->render($this->admin->getTemplate($templateKey), array(
'action' => 'create',
'form' => $view,
'object' => $object,
));
}
}
Service for the controller:
mercury.cargo_recognition.admin.attachment:
class: Mercury\CargoRecognitionBundle\Admin\AttachmentAdmin
tags:
- { name: sonata.admin, manager_type: orm, group: General, label: Attachments }
arguments: [ null, Mercury\CargoRecognitionBundle\Entity\Attachment, "MercuryCargoRecognitionBundle:AttachmentAdmin" ]
I took the solution from the following sites:
Sonata-Users,
Symfony framework forums,
(And the Sonata Project documentation)

It might be useful to override only the preCreate hook with your own logic:
/**
* This method can be overloaded in your custom CRUD controller.
* It's called from createAction.
*
* #param mixed $object
*
* #return Response|null
*/
protected function preCreate(Request $request, $object)
{
}
