Question

[Doctrine\\ORM\\ORMException]   
The EntityManager is closed.  

After I get a DBAL exception when inserting data, EntityManager closes and I\'m not

Answer 1

In Symfony 4.2+ you have to use the package:

composer require symfony/proxy-manager-bridge

otherwiese you get the exception:

Resetting a non-lazy manager service is not supported. Declare the "doctrine.orm.default_entity_manager" service as lazy.  

Than you can reset the entityManager like this:

services.yaml:

App\Foo:
    - '@doctrine.orm.entity_manager'
    - '@doctrine'

Foo.php:

use Doctrine\Bundle\DoctrineBundle\Registry;
use Doctrine\DBAL\DBALException;
use Doctrine\ORM\EntityManagerInterface;


 try {
    $this->entityManager->persist($entity);
    $this->entityManager->flush();
} catch (DBALException $e) {
    if (!$this->entityManager->isOpen()) {
        $this->entityManager = $this->doctrine->resetManager();
    }
}
