How to create a WHERE ... OR ... query with MongoDB in Symfony2?

Question

Inside my UserRepository I want to create custom queries, like the ones I can create with $dm->createQuery('some query') when not using MongoDB.

How can I do this? I see that $this->createQueryBuilder() method exists, but $this->createQuery() does not.

I also tried this as it would make sense, but didn't work:

$this->createQueryBuilder('u')
    ->where(array('$or' => array(
        array('u.username' => $username),
        array('u.email' => $username)
    )))
    // ...

It says that $or is an invalid operator.

Answer 1

Found it here: Doctrine2 Mongodb adding more $or operator

/**
 * Adds an "or" expression to the current query.
 *
 * You can create the expression using the expr() method:
 *
 *     $qb = $this->createQueryBuilder('User');
 *     $qb
 *         ->addOr($qb->expr()->field('first_name')->equals('Kris'))
 *         ->addOr($qb->expr()->field('first_name')->equals('Chris'));
 *
 * @param array|QueryBuilder $expression
 * @return Builder
 */



/**
 * Adds an "and" expression to the current query.
 *
 * You can create the expression using the expr() method:
 *
 *     $qb = $this->createQueryBuilder('User');
 *     $qb
 *         ->addAnd($qb->expr()->field('first_name')->equals('Kris'))
 *         ->addAnd($qb->expr()->field('first_name')->equals('Chris'));
 *
 * @param array|QueryBuilder $expression
 * @return Query
