FOSMessageBundle in Symfony2

Question

How do i set, when i create a thread, that the message is read by the creator of the thread?

I have this portion of code

$composer = $this->get('fos_message.composer');
    $message  = $composer->newThread()
        ->setSender($this->getUser())
        ->setSubject('myThread')
        ->setBody($request->get('createThread')['my_thread']);

    $sender = $this->get('fos_message.sender');
    $sender->send($message);

But when i send the message in the last line, in the database the value of is_read is set to 0, when the sender should be set to 1. So, i need to set the author to is read when he send the message.

Anyone? :)

Message metadata doesn't exist until message is persisted. That's why you have to set read status after saving message to database.

The easiest way to do this is registering EventSubscriber. Working example code:

<?php
namespace Acme\DemoBundle\EventListener;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use FOS\MessageBundle\Event\MessageEvent;
use FOS\MessageBundle\Event\FOSMessageEvents as Event;
use FOS\MessageBundle\ModelManager\MessageManagerInterface;

class MessageSendSubscriber implements EventSubscriberInterface
{
    private $messageManager;

    public function __construct(MessageManagerInterface $messageManager)
    {
        $this->messageManager = $messageManager;
    }

    public static function getSubscribedEvents()
    {
        return array(
            Event::POST_SEND => 'markAsReadBySender'
        );
    }

    public function markAsReadBySender(MessageEvent $event)
    {
        $message = $event->getMessage();
        $sender = $message->getSender();

        $this->messageManager->markAsReadByParticipant($message, $sender);
        $this->messageManager->saveMessage($message);
    }
}

In services.yml:

message_send_listener:
    class: Acme\DemoBundle\EventListener\MessageSendSubscriber
    arguments: [@fos_message.message_manager]
    tags:
        - { name: kernel.event_subscriber }
