Propel2, createdBy field

Question

Let's say I have model "Question". Every question is created by user (current user). How to "auto" update createdBy to current.user

In Doctrine2 I should have event listener with dependency on security.context. And event will subscribe for preSave(), setting $question->setCreatedBy( $context->getToken()->getUser());

How to achieve this with Propel2 ? I could set createdBy in controller, but this is ugly :(

I could write custom behavior, but how to access security.context from the behavior ?

After ~ half year I found working solution :)

Idea: Model will have setter injection for Event Dispatcher. On pre-save model will fire event (validation/user injection etc..). This way I require ED for save. I can select objects from the DB without injected ED. Dependency manager will manage "repository". Repo will be able to inject all required dependencies on the model and then call save. $depepndanciesManager->getModelRepo->save($model). Witch will do: $model->setEventDispacher($this->getEventDispacher); $model->save();

Example of Model:

class Lyric extends BaseLyric
{
    private $eventDispacher;

    public function preSave(ConnectionInterface $con = null)
    {
        if (!$this->validate()) {
            // throw exception
        }

        $this->notifyPreSave($this);
        return parent::preSave($con);
    }

    private function getEventDispacher()
    {
        if ($this->eventDispacher === null) {
            throw new \Exception('eventDispacher not set');
        }
        return $this->eventDispacher;
    }
    public function setEventDispacher(EventDispacher $eventDispacher)
    {
        $this->eventDispacher = $eventDispacher;
    }
    private function notifyPreSave(Lyric $lyric)
    {
        $event = new LyricEvent($lyric);
        $this->getEventDispacher()->dispatch('tekstove.lyric.save', $event);
    }
}

Example of Repository:

class LyricRepository
{
    private $eventDispacher;

    public function __construct(EventDispacher $eventDispacher)
    {
        $this->eventDispacher = $eventDispacher;
    }

    public function save(Lyric $lyric)
    {
        $lyric->setEventDispacher($this->eventDispacher);
        $lyric->save();
    }
}

Example usage from controller:

public function postAction(Request $request)
{
    $repo = $this->get('tekstove.lyric.repository');
    $lyric = new \Tekstove\ApiBundle\Model\Lyric();
    try {
        $repo->save($lyric);
        // return ....
    } catch (Exception $e) {
        // ...
    }
}

Example config:

tekstove.lyric.repository:
    class: Tekstove\ApiBundle\Model\Lyric\LyricRepository
    arguments: ["@tekstove.event_dispacher"]
