Symfony 3 - How to set currently logged user as entity "author"

Question

Let's assume, that I have two entity classes:
\AppBundle\Entity\User - user provider;
\AppBundle\Entity\Article - simple article.

The Article class also have these properties:
author - indicating on user which created this particular entity;
updatedBy - indicating on user which lately updated content of particular article.

How to pass currently logged user object to Article entity to set specific values on author and/or updatedBy properties on backend generated by EasyAdminBundle on Symfony 3.0.1?

Answer 1

If you are in a Controller you just do that

$article->setAuthor($this->getUser());
$article->setUpdatedBy($this->getUser());

Or

If you want that this is automatic

You need to declare a listener on Doctrine event. In your case I guess on preUpdate by including the current user.

There is a very nice documentation here http://symfony.com/doc/current/cookbook/doctrine/event_listeners_subscribers.html

I edit here to answer at your comment

Don't worry you can inject the user entity when you declare your listener as Service

For example :

services:
    your_listener:
        class:     App\AppBundle\Your_Listener
        arguments: ["@security.token_storage"]

Your listener :

private $current_user;

public function __construct($security_context) {
        if ($security_context->getToken() != null) {
            $this->current_user = $security_context->getToken()->getUser();
        }
    } 

Now you can do

$entity= $args->getEntity(); // get your Article

if (!$entity instanceof Article) {
        return;
}

$entity->setAuthor($this->current_user);
$entity->setUpdatedBy($this->current_user);
