预设当前用户[英] PrePersit current user

问题描述

[SETTINGS]

• Symfony 3.4
• Logged user (FosUserBundle)
• Projet Entity (below)

src/AppBundle/Entity/Projet.php

class Projet {
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;
    /**
     * @var string
     *
     * @ORM\Column(name="titre", type="string", length=50)
     */
    private $titre;
    /**
     * @var \DateTime
     *
     * @ORM\Column(name="creation", type="datetime")
     */
    private $creation;
    /**
     * @var \DateTime
     *
     * @ORM\Column(name="modification", type="datetime")
     */
    private $modification;
    /**
     * @var
     *
     * @ORM\ManyToOne(targetEntity="AppBundle\Entity\User", inversedBy="projet")
     * @ORM\JoinColumn(nullable=false)
     */
    private $user;

    /**
     * @ORM\PrePersist
     * @ORM\PreUpdate
     */
    public function updatedTimestamps() {
        $this->setModification(new \DateTime());
        if($this->getCreation() == null) {
            $this->setCreation(new \DateTime());
            $this->setSupprime(false);
        }
    }
}

[PROBLEM]

As is, I'm setting creation and modification on PrePersit/PreUpdate.
I would like to also set the id of the current logged user, how can I do it?

推荐答案

To do this, you need to have access to the security.token_storage service and call $tokenStorage->getToken()->getUser() to retrieve the current user. Since it is not really recommended to inject a service into an entity, you should create an entity listener as described in this section of the doctrine documentation.

Then, by declaring your entity listener as a service and adding the security.token_storage to its constructor arguments like this (in your services.yml):

listener.projet:
    class: AppBundle\Listener\ProjetListener
    arguments: [ "@security.token_storage" ]
    tags:
        - { name: doctrine.orm.entity_listener, lazy: true }

You would be able to access the currently logged in user inside your prePersist and preUpdate methods.

Edit: Here is how your listener should look like

AppBundle/Listener/ProjetListener.php

namespace AppBundle\Listener;

use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;
use Doctrine\ORM\Event\LifecycleEventArgs;
use Doctrine\ORM\Event\PreUpdateEventArgs;
use AppBundle\Entity\Projet;

class ProjetListener
{
    private $tokenStorage;

    public function __construct(TokenStorage $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function prePersist(Projet $projet, LifecycleEventArgs $args)
    {
        // Assigning the current user to the Projet instance being persisted
        $projet->setUser($this->tokenStorage->getToken()->getUser());
        /* .. other actions of prePersist .. */
    }

    public function preUpdate(Projet $projet, PreUpdateEventArgs $args)
    {
        /* .. actions of preUpdate .. */
    }

}

I think you have to do this in a subscriber, listening on prepersist and preupdate doctrine event. You will be able to get the currentn user by injecting the security.token_storage service
