Apiplateform:V3 doesn't send Mercure update when I set my crud operations like Post
if I uncomment the operation below the mercure update fail being sent
update are send only if I don t set the operations manualy

How can I fetch the currently logged in User from anywhere within the Backend code? For example I have an EventSubscriber class and want to fetch it from there.
How can I do that w/o the help of i.e. AbstractController?
Symfony AbstractController is the core of most Controllers. Including EasyAdmin crud controller (XXXCrudController) extends AbstractController so you can access the same methods.
One of those is getUser() which return the current logged in user.
* Get a user from the Security Token Storage.
*
* #return UserInterface|null
*
* #throws \LogicException If SecurityBundle is not available
*
* #see TokenInterface::getUser()
*/
protected function getUser()
{
if (!$this->container->has('security.token_storage')) {
throw new \LogicException('The SecurityBundle is not registered in your application. Try running "composer require symfony/security-bundle".');
}
if (null === $token = $this->container->get('security.token_storage')->getToken()) {
return null;
}
// #deprecated since 5.4, $user will always be a UserInterface instance
if (!\is_object($user = $token->getUser())) {
// e.g. anonymous authentication
return null;
}
return $user;
}
So when trying to get the logged used in a controller, just use this method.
If you want to get the same thing, but for example in a service, you can basically do the same as what the method actually does by using the service injection with TokenStorageInterface to access the TokenStorage service which can get the current user.
So in your event subscriber, add TokenStorageInterface in your constructor to use it to first get the token and then your user. You may have to add another check to see if there is an user logged in (by checking if there is a token for example)
//YourService.php
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
private $tokenStorage
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
}
public function yourMethod()
{
//get token then user
$user = $tokenStorage->getToken()->getUser();
}
I have a command which take a long time to run (it generates a big file).
I would like to use a controller to start it in background and don't wait for the end of its execution to render a view.
Is it possible? If yes, how?
I though the Process class would be useful but the documentation says:
If a Response is sent before a child process had a chance to complete, the server process will be killed (depending on your OS). It means that your task will be stopped right away. Running an asynchronous process is not the same as running a process that survives its parent process.
I solved my problem using the Messenger component as #msg suggested in comments.
To do so, I had to:
install the Messenger component by doing composer require symfony/messenger
create a custom log entity to track the file generation
create a custom Message and a custom MessageHandler for my file generation
dispatch the Message in my controller view
move my command code to a service method
call the service method in my MessageHandler
run bin/console messenger:consume -vv to handle the messages
Here is my code:
Custom log entity
I use it to show in my views if a file is being generated and to let the user download the file if its generation is complete
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\MyLogForTheBigFileRepository")
*/
class MyLogForTheBigFile
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="datetime")
*/
private $generationDateStart;
/**
* #ORM\Column(type="datetime", nullable=true)
*/
private $generationDateEnd;
/**
* #ORM\Column(type="string", length=200, nullable=true)
*/
private $filename;
/**
* #ORM\ManyToOne(targetEntity="App\Entity\User")
* #ORM\JoinColumn(nullable=false)
*/
private $generator;
public function __construct() { }
// getters and setters for the attributes
// ...
// ...
}
Controller
I get the form submission and dispatch a message which will run the file generation
/**
* #return views
* #param Request $request The request.
* #Route("/generate/big-file", name="generate_big_file")
*/
public function generateBigFileAction(
Request $request,
MessageBusInterface $messageBus,
MyFileService $myFileService
)
{
// Entity manager
$em = $this->getDoctrine()->getManager();
// Creating an empty Form Data Object
$myFormOptionsFDO = new MyFormOptionsFDO();
// Form creation
$myForm = $this->createForm(
MyFormType::class,
$myFormOptionsFDO
);
$myForm->handleRequest($request);
// Submit
if ($myForm->isSubmitted() && $myForm->isValid())
{
$myOption = $myFormOptionsFDO->getOption();
// Creating the database log using a custom entity
$myFileGenerationDate = new \DateTime();
$myLogForTheBigFile = new MyLogForTheBigFile();
$myLogForTheBigFile->setGenerationDateStart($myFileGenerationDate);
$myLogForTheBigFile->setGenerator($this->getUser());
$myLogForTheBigFile->setOption($myOption);
// Save that the file is being generated using the custom entity
$em->persist($myLogForTheBigFile);
$em->flush();
$messageBus->dispatch(
new GenerateBigFileMessage(
$myLogForTheBigFile->getId(),
$this->getUser()->getId()
));
$this->addFlash(
'success', 'Big file generation started...'
);
return $this->redirectToRoute('bigfiles_list');
}
return $this->render('Files/generate-big-file.html.twig', [
'form' => $myForm->createView(),
]);
}
Message
Used to pass data to the service
namespace App\Message;
class GenerateBigFileMessage
{
private $myLogForTheBigFileId;
private $userId;
public function __construct(int $myLogForTheBigFileId, int $userId)
{
$this->myLogForTheBigFileId = $myLogForTheBigFileId;
$this->userId = $userId;
}
public function getMyLogForTheBigFileId(): int
{
return $this->myLogForTheBigFileId;
}
public function getUserId(): int
{
return $this->userId;
}
}
Message handler
Handle the message and run the service
namespace App\MessageHandler;
use App\Service\MyFileService;
use App\Message\GenerateBigFileMessage;
use Symfony\Component\Messenger\Handler\MessageHandlerInterface;
class GenerateBigFileMessageHandler implements MessageHandlerInterface
{
private $myFileService;
public function __construct(MyFileService $myFileService)
{
$this->myFileService = $myFileService;
}
public function __invoke(GenerateBigFileMessage $generateBigFileMessage)
{
$myLogForTheBigFileId = $generateBigFileMessage->getMyLogForTheBigFileId();
$userId = $generateBigFileMessage->getUserId();
$this->myFileService->generateBigFile($myLogForTheBigFileId, $userId);
}
}
Service
Generate the big file and update the logger
public function generateBigFile($myLogForTheBigFileId, $userId)
{
// Get the user asking for the generation
$user = $this->em->getRepository(User::class)->find($userId);
// Get the log object corresponding to this generation
$myLogForTheBigFile = $this->em->getRepository(MyLogForTheBigFile::class)->find($myLogForTheBigFileId);
$myOption = $myLogForTheBigFile->getOption();
// Generate the file
$fullFilename = 'my_file.pdf';
// ...
// ...
// Update the log
$myLogForTheBigFile->setGenerationDateEnd(new \DateTime());
$myLogForTheBigFile->setFilename($fullFilename);
$this->em->persist($myLogForTheBigFile);
$this->em->flush();
}
I am trying to send a mail in Symfony 4 with Swiftmailer but I get this error whenever I try to send the mail:
"Cannot autowire argument $notification of "App\Controller\FoundController::show()": it references class "App\Entity\ContactNotification" but no such service exists."
Here is my FoundController:
/**
* #Route("/found/{id}", name="found_view", methods={"GET","POST"})
* #param Found $found
* #param Request $request
* #param ContactNotification $notification
* #return Response
*/
public function show(Found $found, Request $request, ContactNotification $notification): Response
{
$contact = new Contact();
$contact->setFound($found);
$form = $this->createForm(ContactType::class, $contact);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$notification->notify($contact, $found);
$this->addFlash('message', 'Mail sent successfully!');
return $this->redirectToRoute('found_view', [
'id' => $found->getId()
]);
}
return $this->render('found/view.html.twig', [
'found' => $found,
'form' => $form->createView()
]);
}
and the ContactNotification.php
namespace App\Entity;
use App\Entity\Contact;
use App\Entity\Found;
use App\Entity\Lost;
use Twig\Environment;
class ContactNotification{
/**
* #var \Swift_Mailer
*/
private $mailer;
/**
* #var Environment
*/
private $renderer;
public function __construct(\Swift_Mailer $mailer, Environment $renderer)
{
$this->mailer = $mailer;
$this->renderer = $renderer;
}
public function notify(Contact $contact,Found $found){
$message = (new \Swift_Message('Objet:', $contact->getFound()->getName()))
->setFrom($contact->getEmail())
->setTo($found->getUserEmail())
->setReplyTo($contact->getEmail())
->setBody($this->renderer->render('emails/contact.html.twig', [
'contact' =>$contact
]),'text/html');
$this->mailer->send($message);
}
Symfony applications use a Service Container or Dependency Injection Container (DIC) to create instances of PHP classes, that have a service-like character, e.g. Swiftmailer, EntityManager or services you write yourself. An entity is not considered a service, it is often referred to as model. As such it is not managed by the container. Instead they are managed via Doctrine's EntityManager, which can either find (and update or delete) existing models or you create a new model on the spot and save it (using persist and flush operations). Since your ContactNotification is inside the namespace for entities App\Entity\ Symfony's service autowiring will assume that it is an Entity managed by Doctrine, rather than a service.
The solution to your problem would be, to move the ContactNotification to a different folder and namespace, e.g. src/Notifications and thus namespace App\Notifications. This should allow the service to be autowired and then recognized inside the controller.
You can always check if a service was correctly autowired using debug commands:
php bin/console debug:container ContactNotification
or
php bin/console debug:autowiring
I'm having some issues understanding how the Law of Demeter should be applied in some cases with Symfony's DI system.
I have some factory that requires to access current logged in user in the application. To do that I need to require #security.token_storage to inject it as a constructor argument.
But in my factory, to access the user I will need to do : $tokenStorage->getToken()->getUser(), and worst, if I want to access some property of my user, I will need to dive one level deeper.
How would you fix this issue according to the law of demeter ?
Here is a sample of my code :
class SomeFactory
{
/**
* #var User
*/
private $currentUser;
/**
* #param TokenStorageInterface $tokenStorage
*/
public function __construct(TokenStorageInterface $tokenStorage)
{
$this->currentUser = $this->setCurrentUser($tokenStorage);
}
/**
* #param TokenStorageInterface $tokenStorage
*/
protected function setCurrentUser(TokenStorageInterface $tokenStorage)
{
if ($tokenStorage->getToken()
&& $tokenStorage->getToken()->getUser()
&& in_array('ADMIN_ROLE', $tokenStorage->getToken()->getUser()->getRoles())
) {
$this->currentUser = $tokenStorage->getToken()->getUser();
}
}
}
I hope i am being clear.
Thank you very much :)
It seems that in DI factories the session has not been initialized, which makes the current user token unavailable, at this point.
What I did to make it work:
Register a new event listener for kernel.event:
services:
before_request_listener:
class: App\EventListener\MyRequestListener
tags:
-
name: kernel.event_listener
event: kernel.request
method: onKernelRequest
In MyRequestListener I've added my service as dependency (which invokes the factory) and provides the service, with incomplete data. Also I require Security:
public function __construct(\Symfony\Component\Security\Core\Security $security, MyService $service)
{
$this->security = $security;
$this->service = $service;
}
Now, in MyRequestListener::onKernelRequest I can access the user's data and add/change the incomplete properties of my service.
public function onKernelRequest(): void
{
if ($user = $this->security->getUser()) {
$this->service->whatever = $user->whatever;
}
}
Because Symfony uses the same instance of MyService, those modification will be available in all further services.
But keep in mind, that your service, also needs to deal with the incomplete data, when no active user session is existing (e.g. because no user is logged in, or on CLI).
All of my query in Entity Repository needs to be filtered by user.
Now I want to know how can I access the currently logged in user in Entity Repository directly.
What I did today is to get the currently logged in user in my controller, through the use of $this->getUser() and then pass it to Entity Repository and this is not efficient.
You need to inject security.token_storage service into another one to get the current user, but as of Repository classes belong to Doctrine project, not Symfony, it is not recommended to do this.. May be there is a way to achieve it by creating custom entityManager class as described here, but I don't think it would a good solution..
Instead of customizing an entityManager better create a service which calls repository classes' methods, inject desired services into it.. Let Repository classes do their job.
Implementation would be something like this:
RepositoryClass:
class MyRepository extends EntityRepository
{
public function fetchSomeDataByUser(UserInterface $user)
{
// query
}
}
Service:
class MyService
{
private $tokenStorage;
public function _construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
// other services
}
public function getSomeDataByUser()
{
$user = $this->tokenStorage->getToken()->getUser();
return $this->entityManager->getRepository(MyREPOSITORY)->fetchSomeDataByUser($user);
}
}
Usage:
public function someAction()
{
$dataByUser = $this->get(MYSERVICE)->getSomeDataByUser();
}
If you use JMSDiExtraBundle it can be done by adding setter injection:
use Doctrine\ORM\EntityRepository;
use JMS\DiExtraBundle\Annotation as DI;
class YourRepository extends EntityRepository
{
/** #var User current user entity */
protected $user;
/**
* #DI\InjectParams({
* "token_storage" = #DI\Inject("security.token_storage")
* })
*/
public function setSimplaManager(TokenStorageInterface $tokenStorage)
{
$token = $tokenStorage->getToken();
if (!is_object($user = $token->getUser())) {
// e.g. anonymous authentication
return;
}
$this->user = $user;
}
}
