Doctrine findBy 'does not equal'

Question

How do I do

WHERE id != 1

In Doctrine?

I have this so far

$this->getDoctrine()->getRepository('MyBundle:Image')->findById(1);

But how do I do a "do not equals"?

This maybe daft, but I cannot find any reference to this?

Thanks

Answer 1

There is no built-in method that allows what you intend to do.

You have to add a method to your repository, like this:

public function getWhatYouWant()
{
    $qb = $this->createQueryBuilder('u');
    $qb->where('u.id != :identifier')
       ->setParameter('identifier', 1);

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

Hope this helps.

Answer 2

To give a little more flexibility I would add the next function to my repository:

public function findByNot($field, $value)
{
    $qb = $this->createQueryBuilder('a');
    $qb->where($qb->expr()->not($qb->expr()->eq('a.'.$field, '?1')));
    $qb->setParameter(1, $value);

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

Then, I could call it in my controller like this:

$this->getDoctrine()->getRepository('MyBundle:Image')->findByNot('id', 1);

Based on the answer from Luis, you can do something more like the default findBy method.

First, create a default repository class that is going to be used by all your entities.

/* $config is the entity manager configuration object. */
$config->setDefaultRepositoryClassName( 'MyCompany\Repository' );

Then:

<?php

namespace MyCompany;

use Doctrine\ORM\EntityRepository;

class Repository extends EntityRepository {

    public function findByNot( array $criteria, array $orderBy = null, $limit = null, $offset = null )
    {
        $qb = $this->getEntityManager()->createQueryBuilder();
        $expr = $this->getEntityManager()->getExpressionBuilder();

        $qb->select( 'entity' )
            ->from( $this->getEntityName(), 'entity' );

        foreach ( $criteria as $field => $value ) {

            $qb->andWhere( $expr->neq( 'entity.' . $field, $value ) );
        }

        if ( $orderBy ) {

            foreach ( $orderBy as $field => $order ) {

                $qb->addOrderBy( 'entity.' . $field, $order );
            }
        }

        if ( $limit )
            $qb->setMaxResults( $limit );

        if ( $offset )
            $qb->setFirstResult( $offset );

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

}

The usage is the same than the findBy method, example:

$entityManager->getRepository( 'MyRepo' )->findByNot(
    array( 'status' => Status::STATUS_DISABLED )
);

Answer 4

There is now a an approach to do this, using Doctrine's Criteria.

A full example can be seen in How to use a findBy method with comparative criteria, but a brief answer follows.

use \Doctrine\Common\Collections\Criteria;

// Add a not equals parameter to your criteria
$criteria = new Criteria();
$criteria->where(Criteria::expr()->neq('prize', 200));

// Find all from the repository matching your criteria
$result = $entityRepository->matching($criteria);

Answer 5

I solved this rather easily (without adding a method) so i'll share:

use Doctrine\Common\Collections\Criteria;

$repository->matching( Criteria::create()->where( Criteria::expr()->neq('id', 1) ) );

By the way, i'm using the Doctrine ORM module from within Zend Framework 2 and i'm not sure whether this would be compatible in any other case.

In my case, i was using a form element configuration like this: to show all roles except "guest" in a radio button array.

$this->add(array(
    'type' => 'DoctrineModule\Form\Element\ObjectRadio',
        'name' => 'roles',
        'options' => array(
            'label' => _('Roles'),
            'object_manager' => $this->getEntityManager(),
            'target_class'   => 'Application\Entity\Role',
            'property' => 'roleId',
            'find_method'    => array(
                'name'   => 'matching',
                'params' => array(
                    'criteria' => Criteria::create()->where(
                        Criteria::expr()->neq('roleId', 'guest')
                ),
            ),
        ),
    ),
));
