Symfony validator with Doctrine query

I'm writing a forgotten password form and, using PHP validation (as opposed to YML), I am trying to first of all check whether the e-mail address exists.

I think I'm mostly there but I can't seem to run a Doctrine query inside the validator. Here is what I have so far:

class EmailExistsValidator extends ConstraintValidator
{

    public function isValid($value, Constraint $constraint)
    {
        $em = $this->container->get('doctrine.orm.entity_manager');
        $query = $em->createQuery('SELECT COUNT(id) FROM users WHERE email=:email')
            ->setParameter('email', $value);
        $count = $query->getQuery()->getSingleScalarResult();

        if ($count != 1) {
            $this->setMessage($constraint->message);

            return false;
        }

        return true;
    }
}

I get "undefined property - container".

Just pass the doctrine service to the validator like this:

protected $doctrine;

    public function __construct($doctrine) {
        $this->doctrine = $doctrine;
    }

and than in your services.yml:

my_service.my_constraint:
        class: MyCompany\MyBundleBundle\Validator\Constraints\MyValidator
        arguments:
            - '@doctrine'
        tags:
            - { name: validator.constraint_validator, alias: my_name }

and then you can do in your validator like: $this->doctrine->getRepository('...');
