How to fix   Long Method    Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Bug introduced by
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.
