Question

The following would return the a random record with Doctrine:

$name = Doctrine::getTable('nametable')
->createQuery()
->select('name')
->orderBy('RAND()')
->fetchOne();

But I’m running CI2 + Doctrine2, and so it does not work Call to undefined method Doctrine::getTable()

I’ve tried

$data = $this->doctrine->em->getRepository('ORM\Project\Names')
                 ->orderBy('RAND()')
                 ->fetchOne();

But this does not work either: Uncaught exception 'BadMethodCallException' with message 'Undefined method 'orderBy'. The method name must start with either findBy or findOneBy!'

Perhaps findOneBy is what I want, but it expects an array.

Is there an elegant way to fetch a random record in this setup?

Edit:

This is what I’ve come up with:

$query = $this->doctrine->em->createQuery("select max(u.id) from ORM\Dynasties2\Femalenames u");
$result = $query->getSingleResult();
$highval = $result[1];
$random_name = rand(1,$highval);
$name = $this->doctrine->em->find('ORM\Dynasties2\Femalenames', $random_name);
$mother_name = $name->getName();

Surely there is a cleaner way??? Apparently there’s no such thing as RAND() in CI2/Doctrine2, short of just writing a SQL query.

This is what I’ve come up with:

$query = $this->doctrine->em->createQuery("select max(u.id) from ORM\Dynasties2\Femalenames u");
$result = $query->getSingleResult();
$highval = $result[1];
$random_name = rand(1,$highval);
$name = $this->doctrine->em->find('ORM\Dynasties2\Femalenames', $random_name);
$mother_name = $name->getName();

I assumed there was another way, but cannot discover it.
