getting current logged in user - symfony 4

Question

public function agencyHome(EntityManagerInterface $em)
{
    $repository = $em->getRepository(Ships::class);
    // $ships = $repository->findByOwner($own);
    $ships = $repository->findAll();
    return $this->render('agency/index.html.twig', [
        'ships' => $ships,
    ]);
}

on the code above i need to pass current logged in user to a repository, so i can find all related "ships" i tried with $u = $this->getUser()->getId(); with no succes :(

thank you in advance :)

Solution

In a Symfony 4 controller, you should be able to access the user using $this->getUser() within a controller providing that the user is authorized. If there is no logged in user, it should return null.

public function agencyHome(EntityManagerInterface $em)
{
    $this->denyAccessUnlessGranted('ROLE_USER');
    $user = $this->getUser();
}

Alternatively, you should also be able to inject the UserInterface class into the method parameters through which you can get information about the current logged in user.

public function agencyHome(EntityManagerInterface $em, UserInterface $user)
{
   ...
}

I've tested these on a Symfony 4 application, though I can't remember if I had to do anything else in the configuration so please let me know if you have any issues with them.

In what context are you trying to get the current user - is this on the controller layer or the service layer?

[Alexander Br.]

in this controller which extends AbstractController

In general. when using the Doctrine ORM you will never access or use the id. Might need to review the basics.

let's say i want to post a comment by current authenticated user :). how ?

[Alexander Br.]

i know that very well, however, how do i get the ID of the user so i can pass it to a repository, to select some items related to the current user

[jaseeey]

So from my test on my application, I was able to call $this->getUser()->getId() as per your original attempt and it returned me with the user ID. Alternatively, with using the UserInterface injection, I had to get the username with $user->getUsername() and then perform a look up on the UserRepository myself. Are either of these options working for you? Is the user actually being logged in?

I couldn't inject UserInterface but was able to do so with TokenStorageInterface. Calling $this->tokenStorage->getToken()->getUser() retrieves the currently logged in user.
