Standard ManyToMany unidirectional relation between User
and Group
entities from FOSUserBundle
(and SonataUserBundle
). System: Symfony 2.5, Doctrine 2.4.
P.S. this is not real code copied. It is not possible because there are several layers extending with different config files in different formats and places, so if you spot mistype, this is not the problem.
namespace RAZ\UserBundle\Entity;
/**
* @ORM\Table(name="fos_user_user")
*/
class User
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @var Collection
*
* @ORM\ManyToMany(targetEntity="Group")
* @ORM\JoinTable(name="fos_user_user_group")
*/
protected $groups;
}
namespace RAZ\UserBundle\Entity;
/**
* @ORM\Table(name="fos_user_group")
*/
class Group
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
}
Question very similar to: How to get entities in a many-to-many relationship that do NOT have a corresponding linked entity with DQL and Doctrine? The difference is I need to check for only one specific group.
Working SQL (returns 1423):
SELECT COUNT(*) cnt
FROM fos_user_user u
LEFT JOIN fos_user_user_group dug ON u.id = dug.user_id AND dug.group_id = 70
WHERE dug.user_id IS NULL
Incorrectly working DQL (returns 3208):
SELECT COUNT(u)
FROM RAZUserBundle:User u
LEFT JOIN u.groups dug WITH dug.id = 70
WHERE dug IS NULL
Problem is DQL generates different SQL:
SELECT COUNT(u.id)
FROM fos_user_user u
LEFT JOIN fos_user_user_group ug ON u.id = ug.user_id
LEFT JOIN fos_user_group g ON g.id = ug.group_id AND (g.id = 70)
WHERE g.id IS NULL
Any suggestions?
I don't think your DQL is quite right. Can you post it? But in the meantime, this should work.
$em = $this->getDoctrine()->getManager();
$qb = $em->createQueryBuilder();
$result = $qb->select('COUNT(u)')
->from('UserBundle:User' , 'u')
->leftJoin('u.UserGroup','g')
->where('g.GroupId = :id')
->andWhere('g.UserId = :null')
->setParameter('id', 70)
->setParameter('null', null)
->getQuery()
->getOneOrNullResult();
Also writing your DQL this way is easier to read ;)
