$em->flush($entity) flushes all entities scheduled for insert

[jskarpe]

doctrine/orm: v2.5.12

I have an entity without any relations set that I pass to flush().

Expected result

INSERT of only this entity

Actual result

All entities scheduled for inserts are put into the database

Looking at the code, computing changesets for all insert changesets in computeSingleEntityChangeSet seems strange to me:

UnitOfWork.php -> function computeSingleEntityChangeSet contains the following:

// Compute changes for INSERTed entities first. This must always happen even in this case.
$this->computeScheduleInsertsChangeSets();

With computeScheduleInsertsChangeSets:

/**
 * Computes the changesets of all entities scheduled for insertion.
 *
 * @return void
 */
private function computeScheduleInsertsChangeSets()
{
    foreach ($this->entityInsertions as $entity) {
        $class = $this->em->getClassMetadata(get_class($entity));

        $this->computeChangeSet($class, $entity);
    }
}

This is normal: EntityManager#flush($entity) is deprecated, as it was initially only thought for performance optimisations, but does indeed perform any DB operations that were already scheduled.

Please don't use it, and just use EntityManager#flush() instead.
