symfony: [PropertyAccess] Can't access static property $lazyPropertiesNames on Doctrine proxies

Symfony version(s) affected: 5.1.2, and previous versions.

Description

I’m having an issue with the PropertyAccessor component (while using the Serializer component) on an entity managed by Doctrine: Accessing static property Proxies\__CG__\App\Entity\User::$lazyPropertiesNames as non static

Capture d’écran de 2020-06-18 12-27-48

I don’t know if it comes from recent Doctrine updates or from Symfony itself, but some people got the issue on schmittjoh/serializer, see https://github.com/schmittjoh/serializer/issues/1209.

I’ve tried their workaround (downgrade doctrime/orm from 2.7.3 to 2.7.2) but this does not work.

Here is my composer show if it can helps:

How to reproduce

Unfortunately I can’t send a reproducer right now, I’m in a big rush until saturday night.

However @jannmylj posted a reproducer (https://github.com/schmittjoh/serializer/issues/1209#issuecomment-637445190), you may be able to reproducible the issue with the code adapted for the Serializer component.

Possible Solution

I’ve opened a PR to support static properties, see #37335.

I’m not sure this is the real solution, maybe Doctrine-related properties should be ignored by the Serializer component… I don’t know at all 😕

Additional context

No.

[Help] Bug on accessing static property Doctrine proxy with Serializer

Most upvoted comments

Problem is still here with Sf 5.2 using the standard symfony/serializer. Creating custom normalizers for each entity doesn’t sounds like a fix to me.

There are many ways to work around this problem, but i don’t think it is the intended behavior of the serializer, or is it? If not, the issue should be re-opened.

fl0cke on Mar 30, 2021

Well… I fixed my stuff by using createQueryBuilder. I basically did this:

...
//this is running in a foreach where I query multiple entities, hence the $e
....
 $queryBuilder = $this->entityManager->createQueryBuilder();
            $select = ['u'];
            $queryBuilder
                 ->from($e, 'u')
....
             ;

            $this->getAssociations($queryBuilder, $e, $select, 'u');
            $queryBuilder->select($select);
            $result = $queryBuilder->getQuery()->getResult();
....
    private function getAssociations(QueryBuilder $qb, string $classPath, array& $select, string $alias) : void
    {
        $md = $this->entityManager->getClassMetadata($classPath);
        $assoc = $md->getAssociationNames();

        foreach ($assoc as $a) {
            if ($a === 'parent')
                continue;

            if (!in_array($a, $select, true)) {
                $select[] = $a;
                $qb->join("$alias.$a", $a);
                $this->getAssociations($qb, $md->getAssociationTargetClass($a), $select, $a);
            }
        }
    }

getAssociations basically created a joins for all the associations and that forced doctrine to load everything.

The problem is still there in the serializer but I get what I need.

I just added a few properties to the ignored_attributes, and now it works.

Geekimo on Dec 31, 2020

I just got this error in a fresh Symfony project. Seems like a pretty big deal to me if i can’t use the serializer with regular entities anymore?!
