Updating an Object
Once you've fetched an object from Doctrine, updating it is easy. Suppose you have a route that
maps a product id to an update action in a controller:
public function updateAction($id)
{
$em = $this->getDoctrine()->getEntityManager();
$product = $em->getRepository('AcmeStoreBundle:Product')->find($id);
if (!$product) {
}
throw $this->createNotFoundException('No product found for id '.$id);
$product->setName('New product name!');
$em->flush();
}
return $this->redirect($this->generateUrl('homepage'));
Updating an object involves just three steps:
1. fetching the object from Doctrine;
2. modifying the object;
3. calling flush() on the entity manager
Notice that calling $em->persist($product) isn't necessary. Recall that this method simply tells
Doctrine to manage or "watch" the $product object. In this case, since you fetched
the $productobject from Doctrine, it's already managed.
