I have a problem while trying to USE QueryBuilder OR DQL.
I have the following relation:
User <-1:n-> Profile <-n:m-> RouteGroup <-1:n-> Route
I would like to make a DQL that lists all the routes that a specific user has access. I can get this information with the following code:
$usr = $this->container->get('security.context')->getToken()->getUser();
foreach ($usr->getProfiles() as $profile){
foreach ($profile->getRoutegroups() as $routegroup){
var_dump($routegroup->getRoutes()->toArray());
}
}
For obvious reason i cant use this code, otherwise I will overload my server, LOL.
I tried the following approaches:
DQL:
$em->createQuery('SELECT p FROM CRMCoreBundle:User u
JOIN CRMCoreBundle:Profile p
JOIN CRMCoreBundle:RoleGroup rg
JOIN CRMCoreBundle:Role r
WHERE
u.id=:user')
->setParameter('user', $user->getId())
->getResult();
QueryBuilder (i tried using u.profiles - the name of the relationship instead of the entity - but this did not work also):
$em->createQueryBuilder()
->select('r')
->from('CRMCoreBundle:User', 'u')
->innerJoin('u.profiles','p')
->where('u.id = :user_id')
->setParameter('user_id', $user->getId())
->getQuery()
->getResult();
Can someone help please???
UPDATE: I tried Zeljko's solution and made this script:
return $this->getEntityManager()
->createQueryBuilder()
->select('u, r')
->from('CRMCoreBundle:User', 'u')
->innerJoin('u.profiles','p')
->innerJoin('p.routegroups','rg')
->innerJoin('rg.routes','r')
->where('u.id = :user_id')->setParameter('user_id', $user->getId())
->getQuery()
->getResult();
But i got this error:
The parent object of entity result with alias 'r' was not found. The parent alias is 'rg'.
If i change "->select('u, r')" to "->select('r')" i get this:
[Semantical Error] line 0, col -1 near 'SELECT r FROM': Error: Cannot select entity through identification variables without choosing at least one root entity alias.
After trying some alternatives I found out that I could make an inverse lookup, starting from routes to users. The solution was as follows:
return $this->getEntityManager()
->createQueryBuilder()
->select('r')
->from('CRMCoreBundle:Route', 'r')
->innerJoin('r.routegroup','rg')
->innerJoin('rg.profiles','p')
->innerJoin('p.users','u')
->where('u.id = :user_id')
->setParameter('user_id', $user->getId())
->getQuery()
->getResult();
