Fail to load entity that has enum as primary key via ManyToOne association #10471
Description
BC Break Report
| Q | A |
|---|---|
| BC Break | yes |
| Version | 2.14.1 |
Summary
I have an entity "Field" that has a ManyToOne relationship to "FieldType". The ID column of FieldType is backed by a native PHP enum FieldTypeID.
I can load a FieldType entity just fine, but if I load a Field and try to access the FieldType from it, I get an error.
Previous behavior
This was working fine in 2.14.0
Current behavior
Exception is thrown:
Object of class App\Entity\Enum\FieldTypeID could not be converted to string
File: vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php
Line: 1575
How to reproduce
class Field
{
#[ORM\Id]
#[ORM\GeneratedValue(strategy: 'IDENTITY')]
#[ORM\Column(name: 'id', type: Types::INTEGER, nullable: false)]
private ?int $id = null;
#[ORM\ManyToOne(targetEntity: FieldType::class)]
#[ORM\JoinColumn(name: 'type_id', referencedColumnName: 'id', nullable: false)]
private FieldType $type;
public function getId(): ?int
{
return $this->id;
}
public function getType(): ?FieldType
{
return $this->type;
}
}
class FieldType
{
#[ORM\Id]
#[ORM\GeneratedValue(strategy: 'NONE')]
#[ORM\Column(name: 'id', type: Types::INTEGER, nullable: false, enumType: FieldTypeID::class)]
private readonly FieldTypeID $id;
public function getId(): int
{
return $this->id->value;
}
}
enum FieldTypeID: int
{
case FOO = 1;
case BAR = 2;
case BAZ = 3;
}
// accessing FieldType directly works OK
$fieldType = $doctrine->getRepository(FieldType::class)->find(1);
$id = $fieldType->getId();
// accessing via association fails
$field = $doctrine->getRepository(Field::class)->find(1);
$fieldType = $field->getType();
$id = $fieldType->getId(); // exception thrown here
