- Maybe just use simple variable assignment.
- If you want to persist an entity into the database, use $em->persist(), not
$em->merge().
- You only have to call $em->persist() to _update_ an entity if you changed the
Change Tracking Policy to "Deferred Explicit".
$position = 1;
foreach (array_keys($genres) as $genreId) {
$genre = $this->getRepository()->findOneById($genreId);
$genre->setRanking($position);
$this->getObjectManager()->persist($genre); // only for "Deferred
Explicit"
$position++;
}
