// Make the complex query
$rs = $di->get('modelsManager')
    ->createBuilder()
    ->columns('*')
    ->from('Acme\Model\AclRole')
    ->join('Acme\Model\AclResource', 'ar.role_id = Acme\Model\AclRole.id', 'ar')
    ->join('Acme\Model\AclAction', 'aa.resource_id = ar.id', 'aa')
    ->getQuery()
    ->execute();

// Start working with \Phalcon\Mvc\Model\Row
print_r($rs->toArray()); // Here we got notice and warning in server logs
