How to check if entity changed in Doctrine 2?

Question

I need to check if a persisted entity has changed and needs to be updated on the database. What I made (and did not work) was the following:

$product = $enti         


        

Answer 1

I didn't need/want to create Listeners for my case so I ended up with

$product->setName('A different name');
$uow = $entityManager->getUnitOfWork();
$uow->computeChangeSets();
if ($uow->isEntityScheduled($product)) {
    // My entity has changed
}
