Doctrine method find() returns a proxy object

Question

I'm running two equal find methods. One is returning a proxy, the other one is returning a real Entity object.

I can't find a reason why doctrine would handle both differently. Do you have any idea why my first Entity is returned as a proxy?

This project is running:

"doctrine/doctrine-bundle": "^2.6",
"symfony/symfony": "5.4.*",

Following my Test Controller Action:

public function startAction(InstitutionRepository $institutionRepository, CountryRepository $countryRepository): Response
{

    $result = $institutionRepository->find(266);
    $result2 = $countryRepository->find(1);
    return $this->json([$result, $result2]);
}

None of the Entity classes have black magic inside and look equal:

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Institutions.
 *
 * @ORM\Table(name="institutions")
 *
 * @ORM\Entity(repositoryClass="App\Repository\InstitutionRepository")
 */
class Institution
{
    /**
     * @var int
     *
     * @ORM\Column(name="institution", type="integer", nullable=false)
     *
     * @ORM\Id
     *
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="code", type="string", length=10, nullable=false)
     */
    private $code;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255, nullable=false)
     */
    private $name;
    public function getId(): int
    {
        return $this->id;
    }
    public function setId(int $id): void
    {
        $this->id = $id;
    }
    public function getCode(): string
    {
        return $this->code;
    }
    public function setCode(string $code): void
    {
        $this->code = $code;
    }
    public function getName(): string
    {
        return $this->name;
    }
    public function setName(string $name): void
    {
        $this->name = $name;
    }
}

Country Entity:

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Countries.
 *
 * @ORM\Table(name="countries", uniqueConstraints={@ORM\UniqueConstraint(name="code", columns={"code"})})
 *
 * @ORM\Entity(repositoryClass="App\Repository\CountryRepository")
 */
class Country
{
    /**
     * @var int
     *
     * @ORM\Column(name="country", type="integer", nullable=false)
     *
     * @ORM\Id
     *
     * @ORM\GeneratedValue(strategy="IDENTITY")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="code", type="string", length=10, nullable=false)
     */
    private $code;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=45, nullable=false)
     */
    private $name;

    /**
     * Get id.
     *
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set code.
     *
     * @param string $code
     *
     * @return Country
     */
    public function setCode($code)
    {
        $this->code = $code;

        return $this;
    }

    /**
     * Get code.
     *
     * @return string
     */
    public function getCode()
    {
        return $this->code;
    }

    /**
     * Set name.
     *
     * @param string $name
     *
     * @return Country
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name.
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }
}

And both Repository methods are almost empty:

<?php

declare(strict_types=1);

namespace App\Repository;

use App\Entity\Country;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;

/**
 * @extends ServiceEntityRepository<Country>
 */
class CountryRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Country::class);
    }
}

InstitutionRepository:

<?php

declare(strict_types=1);

namespace App\Repository;

use Database\OrganisationBundle\Entity\Institution;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Persistence\ManagerRegistry;

/**
 * @extends ServiceEntityRepository<Country>
 */
class InstitutionRepository  extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Institution::class);
    }


}

The serialized Result looks like this:

[
  {
    "id": 266,
    "code": "LGSE_QS_IN",
    "name": "LGSE QS Test Institution",
    "__initializer__": null,
    "__cloner__": null,
    "__isInitialized__": true
  },
  {
    "id": 1,
    "code": "AF",
    "name": "Afghanistan"
  }
]

I'm totally out of ideas. Maybe someone experienced something like this already with Symfony and Doctrine?

Answer 1

There is a mistake in your InstitutionRepository.

@extends ServiceEntityRepository<Country>

should be

@extends ServiceEntityRepository<Institution>
