Dependency Inject non-default Entity Manager into Service in Symfony

Question

I want to change from the default em to an em called \'ps\'. The configuration is correct and in the controller I can simply type $this->getManager(\'ps\')->getC

Answer 1

If your service class just needs the connection then it easiest way it make your own connection class and inject it.

namepace AppBundle\Connection;

class PsConnection extends Doctrine\DBAL\Connection
{
}

# doctrine.yaml
doctrine:
    dbal:
        connections:
            ps:
                wrapper_class: AppBundle\Connection\PsConnection

class HilaService
{
    public function __construct(AppBundle\Connection\PsConnection $conn)

Everything will work as before but you can get the connection directly.

if you really do need the entity manager then you can make a service definition:

# services.yaml
AppBundle\Service\HilaService:
    $entityManager: '@doctrine.orm.ps_entity_manager'

Finally, if you don't want to fool around with any of this stuff you can inject the ManagerRegistry and pull what you need from it.

class HilaService
{
    public function __construct(Doctrine\Common\Persistence\ManagerRegistry $managerRegistry)
    {
        $em = $managerRegistry->getManager('ps'); // or getConnection()
