Doctrine ORM Entity class name is returning a Proxy class name

Question

I am currently retrieving the class name of my entities to save changes into a log. This happens in a listener:

In my service layer:

$product = $line->getProduct();

$product->setAvailability($product->getAvailability() - $line->getAmount());
$em->persist($product);

the problem is that by doing following in a listener:

$className = join('', array_slice(explode('\\', get_class($entity)), -1));
$modification->setEntidad($className);

The $className that is set into the modification is miomioBundleEntityProductoProxy.

How can I get the real class name for my entity, and not the proxy class name?

I neither have an idea of what your problem is nor what your question is. Please consider rephrasing your question so it can be understand. — Sgoettschkes

As the proxy class always extends from the real entity class:

class <proxyShortClassName> extends \<className> implements \<baseProxyInterface>

then, you can get it with class_parents() function:

if ($entity instanceof \Doctrine\Common\Proxy\Proxy) {
    $class = current(class_parents($entity)); // get real class
}

Especially useful when you don't have access to EntityManager instance.

The fact that you receive a proxy name when calling get_class on a proxy is quite normal, since proxies are a required concept to let the ORM and lazy loading of associations work.

You can get the original class name by using following API:

$realClassName = $entityManager->getClassMetadata(get_class($object))->getName();

Then you can apply your own transformations:

$normalizedClassName = join('', array_slice(explode('\\', $realClassName), -1));

$modificacion->setEntidad($normalizedClassName);

it's faster to use ClassUtils::getRealClass($className)

That's not going to retrieve the class name in all cases. You shouldn't do that manually as it's an implementation detail.
