查询未获取相关表中的所有结果

Question

In my symfony test project I have two tables whereby users is related to flight. Flight has fk to users in this structure

users

id | name | email |
1  | fen  | f.com |
2  | foo  | o.com |

flight
id | path | desc | dureation | users|
1  | 123  | xyz  | 3         | 1

I am using below query in a repository to pull for all the data where user id is 1.

class FlightRepository extends \Doctrine\ORM\EntityRepository
{
    public function findWithFlights($id)
{
    $queryBuilder = $this->createQueryBuilder('u')
        ->join('u.flights', 'i')
        ->where('u.id = :id')
        ->setParameter('id', $id);
    return $queryBuilder->getQuery()->getResult();
}

the above only returns flight field of path in this case 123 when called with the below in controller

$restresults2 = $this->getDoctrine()
            ->getRepository('MyBundle:Flights')
                ->findWithFlights($id);
$response = new Response(json_encode($restresults2));
        $response->headers->set('Content-Type', 'application/json');

return $response;

Please what could be wrong with my repo query

Answer 1

Ok, there are some things wrong here. But first of all, you should ask yourself: should users and flight not have a many-to-many realtionship? In your current model one flight can only have one user, and the same user can be connected to many flights. Do you really want this?

Then when you query, you should ask yourself; do I want a result of users or a result of flight and create your query builder in the repository you want to have your results of.

If you want all the flights of a user this should be your query:

class FlightRepository extends \Doctrine\ORM\EntityRepository
{
public function findWithFlights($id)
{
$queryBuilder = $this->createQueryBuilder('f')
    ->join('f.users', 'u')
    ->where('u.id = :id')
    ->setParameter('id', $id);
return $queryBuilder->getQuery()->getResult();
}

Answer 2

User fields are not there cause by default doctrine is fetching only entity data that belongs to the corresponding repository. (select('u')). Add a proper select statement to show Doctrine what you want to fetch. I believe in your case it would be select(['u', 'i'])

class FlightRepository extends \Doctrine\ORM\EntityRepository
{
  public function findWithFlights($id) {
    $queryBuilder = $this->createQueryBuilder('u')
      ->select(['u', 'i'])
      ->join('u.flights', 'i')
      ->where('u.id = :id')
      ->setParameter('id', $id);

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