[FIXED] Symfony Fixture - Reference does not exist

Issue

I try to write fixtures in multiple files, I've never created fixtures by setting object, so I try to follow SF doc (https://symfony.com/bundles/DoctrineFixturesBundle/current/index.html#loading-the-fixture-files-in-order)

I have this error: Reference to "lang49" does not exist lang49 being first object set

LangFixture:

use App\Entity\Lang;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;

class LangFixture extends Fixture
{
    public const ENGLISH_LANG_REFERENCE = 'lang39';
    public const FRENCH_LANG_REFERENCE = 'lang49';
    public const SPANISH_LANG_REFERENCE = 'lang41';
    public const TURKISH_LANG_REFERENCE = 'lang163';

    public function load(ObjectManager $manager): void
    {
...
        $lang39 = new Lang();
        $lang39->setLang("en");
        $lang39->setName("English");
        $lang39->setEnglishName("English");
        $lang39->setEnabled(true);
        $manager->persist($lang39);
        $this->addReference(self::ENGLISH_LANG_REFERENCE, $lang39);
...
        $lang41 = new Lang();
        $lang41->setLang("es");
        $lang41->setName("Español");
        $lang41->setEnglishName("Spanish; Castilian");
        $lang41->setEnabled(true);
        $manager->persist($lang41);
        $this->addReference(self::SPANISH_LANG_REFERENCE, $lang41);
...
        $lang49 = new Lang();
        $lang49->setLang("fr");
        $lang49->setName("Français");
        $lang49->setEnglishName("French");
        $lang49->setEnabled(true);
        $manager->persist($lang49);
        $this->addReference(self::FRENCH_LANG_REFERENCE, $lang49);
...
        $lang163 = new Lang();
        $lang163->setLang("tr");
        $lang163->setName("Türkçe");
        $lang163->setEnglishName("Turkish");
        $lang163->setEnabled(false);
        $manager->persist($lang163);
        $this->addReference(self::TURKISH_LANG_REFERENCE, $lang163);
...
        $manager->flush();
    }
}

UserFixture:

use App\Entity\User;
use App\DataFixtures\LangFixture;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Common\DataFixtures\DependentFixtureInterface;
use Doctrine\Persistence\ObjectManager;

class UserFixture extends Fixture
{
    public const ADMIN_USER_REFERENCE = 'admin';
    public const VISITOR_USER_REFERENCE = 'visitor';
    
    public function load(ObjectManager $manager): void
    {
        $admin = new User();
        $admin->setLang($this->getReference(LangFixture::FRENCH_LANG_REFERENCE));
        $admin->addLang($this->getReference(LangFixture::FRENCH_LANG_REFERENCE));
        $admin->addLang($this->getReference(LangFixture::ENGLISH_LANG_REFERENCE));
        $admin->addLang($this->getReference(LangFixture::SPANISH_LANG_REFERENCE));
        $admin->setEmail('example1@mail.com');
        $admin->setRoles(["ROLE_SUPER_ADMIN"]);
        ...
        $admin->setLangContributor(true);
        $admin->addContributorLang($this->getReference(LangFixture::TURKISH_LANG_REFERENCE));
        $admin->setIsVerified(true);
        $manager->persist($admin);
        $this->addReference(self::ADMIN_USER_REFERENCE, $admin);

        $visitor = new User();
        $visitor->setLang($this->getReference(LangFixture::FRENCH_LANG_REFERENCE));
        $visitor->addLang($this->getReference(LangFixture::FRENCH_LANG_REFERENCE));
        $visitor->setEmail('example2@mail.com');
        $visitor->setRoles(["ROLE_SUPER_VISITOR"]);
        ...
        $admin->setLangContributor(false);
        $visitor->setIsVerified(true);
        $manager->persist($visitor);
        $this->addReference(self::VISITOR_USER_REFERENCE, $visitor);
        
        $manager->flush();
    }

    public function getDependencies()
    {
        return [
            LangFixture::class,
        ];
    }
}

Then UserFixture addReferences will be use into MessageFixture...

What's wrong? Thanx

UPDATED, now it's ok thanx to exepti0n

Solution

You're using class constants for your languages references, but your are not using them for setting the reference.

$this->addReference('ENGLISH_LANG_REFERENCE', $lang39);
// Results in a reference called "ENGLISH_LANG_REFERENCE"

$this->addReference(self::ENGLISH_LANG_REFERENCE, $lang39);
// Results in a reference called "lang39" since that is the value of your constant

Since you are using dependent fixtures your UserFixture should implement DependentFixtureInterface.

// Old
class UserFixture extends Fixture {

// New
use Doctrine\Common\DataFixtures\DependentFixtureInterface;

class UserFixture extends Fixture implements DependentFixtureInterface {
