Database Handling

At the moment there are no good general best practices for how to integrate database support into your bundle. Consider looking at one of the existing bundles that require a database for how to set things up.

  • All database tables need to be prefixed with the bundle unique name .e.g uniquename_tablename

// In *Extension.php, using the ExtensionTrait
public function prepend(ContainerBuilder $container)
    $this->registerEntityManager($container, 'dbp_relay_myname_bundle');
    // ...
