在理论上与邻居建立多对多关系

Question

Many User entities has many House entities using joint table in annotation

class User
{
    /**
     * @ORM\ManyToMany(targetEntity="House")
     * @ORM\JoinTable(name="house_user",
     *   joinColumns={@ORM\JoinColumn(name="user_uuid", rerencedColumnName="uuid") },
     *   inverseJoinColumns={@ORM\JoinColumn(name="house_uuid", ferencedColumnName="uuid") }
     *   }
     * )
     */
    public $houses;

I need to get all neighbors from all houses where given user living inclungin user itself. Also I need to get counter of this neighbours.

Using SQL i can get this by join joint table 2 times:

select DISTINCT usr.*
FROM users usr
       LEFT JOIN house_user houseDUser ON houseDUser.user_uuid = 'uuid-v4-goes-here'
       LEFT JOIN house h on houseDUser.housing_complex_uuid = h.uuid
       LEFT JOIN house_user houseUser ON houseUser.housing_complex_uuid = h.uuid
WHERE usr.uuid = houseUser.user_uuid

And so I can get neighbors using QueryBuilder (but not so elegant, i think):

    $qb = $this->reateQueryBuilder('usr')
        ->addSelect('users')
        ->leftJoin(HouseUser::class, 'houses', Join::WITH, 'usr MEMBER OF houses.users')
        ->leftJoin(User::class, 'users', Join::WITH, 'users MEMBER OF houses.users')
        ->where('usr = :userUuid')
        ->setParameter('userUuid', (string)$user->getUuid());

    $paginator = new Paginator($qb);
    $count = count($paginator);

But as a count i got 1 everytime. Is there the right way to do queries like this?
