Doctrine findBy 'does not equal' - doctrine-orm

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 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 2

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.

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' );
Or you can edit this in config.yml
doctrine:
orm:
default_repository_class: 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 => $value ) {
// IF INTEGER neq, IF NOT notLike
if($this->getEntityManager()->getClassMetadata($this->getEntityName())->getFieldMapping($field)["type"]=="integer") {
$qb->andWhere( $expr->neq( 'entity.' . $field, $value ) );
} else {
$qb->andWhere( $expr->notLike( 'entity.' . $field, $qb->expr()->literal($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 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([
'type' => 'DoctrineModule\Form\Element\ObjectRadio',
'name' => 'roles',
'options' => [
'label' => _('Roles'),
'object_manager' => $this->getEntityManager(),
'target_class' => 'Application\Entity\Role',
'property' => 'roleId',
'find_method' => [
'name' => 'matching',
'params' => [
'criteria' => Criteria::create()->where(
Criteria::expr()->neq('roleId', 'guest')
)
],
],
],
]);

I used the QueryBuilder to get the data,
$query=$this->dm->createQueryBuilder('AppBundle:DocumentName')
->field('fieldName')->notEqual(null);
$data=$query->getQuery()->execute();
