Doctrine Many to Many relations - sql

Question

i edit the thread for put more info.
I have the "User" entity and the "Rol" entity, and i am fighting to do work the collection of Roles of a User.
In the User entity i defined:
/**
* #ManyToMany(targetEntity="AppsManantiales\CommonBundle\Entity\Perfil")
* #JoinTable(name="usuarios_perfiles",
* joinColumns={#JoinColumn(name="idUsuario", referencedColumnName="idusuario")},
* inverseJoinColumns={#JoinColumn(name="idPerfil", referencedColumnName="idperfil")}
* )
*/
protected $perfiles;
And in the constructor:
public function __construct(){
$this->perfiles = new \Doctrine\Common\Collections\ArrayCollection();
$this->contacto = new \Doctrine\Common\Collections\ArrayCollection();
}
Before the class namespace put:
use AppsManantiales\CommonBundle\Entity\Perfil;
When execute:
php app/console generate:doctrine:entities CommonBundle
An error appear:
[Doctrine\Common\Annotations\AnnotationException]
[Semantical Error] The annotation "#ManyToMany" in property AppsManantiales\CommonBundle\Entity\Usuario::$perfiles was never impo
rted. Did you maybe forget to add a "use" statement for this annotation?
Any ideas ?.

Answer 1

First part: So in this case, u got a relation many-to-many between Role entity and User entity. First of all, check, r entities correct after generting. Here u can find examples of establishing different realtions: http://docs.doctrine-project.org/en/latest/reference/association-mapping.html && http://docs.doctrine-project.org/en/2.0.x/reference/association-mapping.html (the second has more information with examples of Doctrine queries)
Second part of your question: after establishing right relations, select query of your User gonna be smth like:
$user = $em->createQueryBuilder()
->select('u, r')
->from('YourBundle:User', 'u')
->innerJoin('u.roles', 'r')
->where('u.id IN (:ids)')
->setParameter('ids', $ids)
->getQuery()
->getResult();
And as u guess, u can get roles with the help of your accessor: $user->getRoles()
p.s. yes, ofcource if all entities r correct, u can add methods manually.
EDITED
Oh sry, I forgot, u use Symfony2. So by default in your entities, u got such line:
use Doctrine\ORM\Mapping as ORM;
As u can notice, all annotations u used were with prefix #ORM\. exmpls:
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
So just add prefix #ORM and the result:
/**
* #ORM\ManyToMany(targetEntity="AppsManantiales\CommonBundle\Entity\Perfil")
* #ORM\JoinTable(name="usuarios_perfiles",
* joinColumns={#ORM\JoinColumn(name="idUsuario", referencedColumnName="idusuario")},
* inverseJoinColumns={#ORM\JoinColumn(name="idPerfil", referencedColumnName="idperfil")}
* )
