			0 ignored issues – show Bug introduced 2016-01-14 13:56 UTC by Report Bug Copy Issue Report You have injected the EntityManager via parameter `$entityManager`. This is generally not recommended as it might get closed and become unusable. Instead, it is recommended to inject the ManagerRegistry and retrieve the EntityManager via `getManager()` each time you need it. The `EntityManager` might become unusable for example if a transaction is rolled back and it gets closed. Let’s assume that somewhere in your application, or in a third-party library, there is code such as the following: function someFunction(ManagerRegistry $registry) { $em = $registry->getManager(); $em->getConnection()->beginTransaction(); try { // Do something. $em->getConnection()->commit(); } catch (\Exception $ex) { $em->getConnection()->rollback(); $em->close(); throw $ex; } } If that code throws an exception and the `EntityManager` is closed. Any other code which depends on the same instance of the `EntityManager` during this request will fail. On the other hand, if you instead inject the `ManagerRegistry`, the `getManager()` method guarantees that you will always get a usable manager instance. Loading history...
