Break in 2.8: Cannot bind QueryBuilder parameters with \IteratorAggregate entities: leads to incorrect SQL generated code #8365
Description
Bug Report
Binding QueryBuilder query parameters to entities that implements \IteratorAggregate leads to incorrect DQL generated code.
| Q | A |
|---|---|
| BC Break | yes |
| Version | 2.8.x-dev 418587b |
| Working on | 2.7 branch |
It seems that QueryBuilder tries to serialize object instead of using its primary key:
// Node is a valid Doctrine entity with primary key
// Node implements \IteratorAggregate, \Countable
$node = $this->_em->find(Node::class, $nodeId);
// …
$qb = $this->createQueryBuilder('t');
$qb->select('t')
->innerJoin('t.nodeSources', 'ns')
->andWhere($qb->expr()->eq('ns.node', ':node'))
->setParameter('node', $node);leads into:
An exception occurred while executing […]
n1_.node_id = ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?
with params [7, false, false, false, false, false, false, false, false, false, false, false, false]:
To fix this I need to explicitely use primary key $node->getId():
$qb = $this->createQueryBuilder('t');
$qb->select('t')
->innerJoin('t.nodeSources', 'ns')
->andWhere($qb->expr()->eq('ns.node', ':node'))
->setParameter('node', $node->getId());
