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"]
Config is based on symfony framework.
Real implementation:
Links may not work, project is in active development!
