symfony2 first doctrine query

Question

I am trying make my first query on symfony2 so the question will be maybe stupid.

I have my table with users and table with (friends) requests. In requests table i store

id,nick(id),odobera(another user Id- who i follow),time

And the nick property looks:

/**
 * @ORM\ManyToOne(targetEntity="TB\UserBundle\Entity\User", inversedBy="Requests")
 * @ORM\JoinColumn(name="nick", referencedColumnName="id")
 */

And now i want rebuild my old functional query to the new symfony one:

    $select_all=mysql_query("SELECT re.*,tb.rank,tb.profile_picture_ultra_small,tb.country,tb.typ_hraca,tb.rank 
                            FROM requests as re
                            INNER JOIN tb_users as tb
                            ON re.nick=tb.nick
                            WHERE re.odobera='$nick' AND re.nick<>'$nick' ORDER BY re.id DESC LIMIT 50");

I started just simply:

public function getMyFollowers($my_id)
{
    $qb = $this->createQueryBuilder('mf')
               ->select('mf')
               ->where('mf.odobera = :my_id')
               ->addOrderBy('mf.time','DESC')
               ->setParameter('my_id', $my_id)
               ->setMaxResults(50);

    return $qb->getQuery()
              ->getResult();
}  

I dont have there the inner join for selecting profile_picture of user who follow me + my result looks weird when i dump it now: (as you can see there is no ID (nick) of the user who follow me)

"Proxies\__CG__\TB\UserBundle\Entity\User" ["odobera"]=> int(25) ["time"]=> int(1359128544) ["viewed"]=> bool(true) } [6]=> object(stdClass)#624 (6) { ["__CLASS__"]=> string(33) "TB\RequestsBundle\Entity\Requests" ["id"]=> int(57443) ["nick"]=> string(40) "Proxies\__CG__\TB\UserBundle\Entity\User" ["odobera"]=> int(25) ["time"]=> int(1359124714) ["viewed"]=> bool(true) } [7]=> object(stdClass)#625 (6) { ["__CLASS__"]=> string(33) "TB\RequestsBundle\Entity\Requests" ["id"]=> int(57013) ["nick"]=> string(40) "Proxies\__CG__\TB\UserBundle\Entity\User" ["odobera"]=> int(25) ["time"]=> int(1359047459) ["viewed"]=> bool(true) } [8]=> object(stdClass)#626 (6) { ["__CLASS__"]=> string(33) "TB\RequestsBundle\Entity\Requests" ["id"]=> int(56766) ["nick"]=> string(40) 

Any ideas please? :P Thx!

i tried add this to my entity as you said but changed the names but i think it doesn't make sence at all and my query was loading 9s in one time and withdrawed just one user + i cant load the page now... USERS:

/**
 * @ORM\OneToMany(targetEntity="TB\RequestsBundle\Entity\Requests", mappedBy="following")
 *
 **/
private $followers;

REQUESTS:

/**
* @ORM\ManyToOne(targetEntity="TB\UserBundle\Entity\User", inversedBy="followers")
* @ORM\JoinColumn(name="nick", referencedColumnName="id")
**/

private $following;

But ... it doesn't make sence..

You can define a Repository for user class adding the annotation to User class.

@ORM\Entity(repositoryClass="Acme\YourBundle\Entity\UserRepository")

And inside the repository you will have:

public function getFollowers($id)
{
    $qb = $this->getEntityManager()->createQueryBuilder();
    $qb
        ->select('user')
        ->from('YourBundle:User', 'user')
        ->leftJoin('user.requests', 'friends')
        ->where('friends.odobera = :id')
        ->setParameter('id', $id)
        ->orderBy('friends.time', 'DESC')
        ->setMaxResults(50);

    return $qb->getQuery()->getResult();
}

Check this Custom Repositories

On your controller

$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('YourBundle:User')->getFollowers($id);

Mapping info example

On Users

/**
 * @ORM\OneToMany(targetEntity="Followers", mappedBy="following")
 *
 **/
private $followers;

On Followers (the table were you defined the followers)

/**
 * @ORM\ManyToOne(targetEntity="Users", inversedBy="followers")
 * @ORM\JoinColumn(name="company_id", referencedColumnName="id")
 **/
private $following;
