Download the PHP package steevanb/doctrine-entity-merger without Composer

doctrine-entity-merger

But, if you execute 2 PARTIAL on same entity, but not same fields, you will have this problem :

You can use _steevanb\DoctrineEntityMerger\QueryHint::MERGEENTITY to define description in $foo1 :

steevanb/doctrine-events

Add it to your composer.json :

Add EntityMergerSubscriber :

If you want to add MERGE_ENTITY hint to all of your queries, you can do this :

For example, if you are on a Symfony project, you can add it in AppKernel :

# app/AppKernel.php

use Doctrine\ORM\EntityManagerInterface;
use steevanb\DoctrineEntityMerger\QueryHint;
use steevanb\DoctrineEntityMerger\EventSubscriber\EntityMergerSubscriber;

class AppKernel
{
    public function boot()
    {
        parent::boot();

        foreach ($this->getContainer()->get('doctrine')->getManagers() as $manager) {
            if ($manager instanceof EntityManagerInterface) {
                // add hint MERGE_ENTITY to all your queries
                $manager->getConfiguration()->setDefaultQueryHint(QueryHint::MERGE_ENTITY, true);

                // add listener, who use steevanb/doctrine-events to change UnitOfWork::createEntity()
                // to take into account MERGE_ENTITY hint
                $manager->getEventManager()->addEventSubscriber(new EntityMergerSubscriber());
            }
        }
    }
}
