Description
I probably problem with Ignore attribute and DiscriminatorMap at symfony 7.1.5
Example case:
<?php
declare(strict_types=1);
namespace App\Test;
use Symfony\Component\Serializer\Attribute\DiscriminatorMap;
use Symfony\Component\Serializer\Attribute\Ignore;
#[DiscriminatorMap(
typeProperty: 'type',
mapping: [
'base_payload' => BasePayload::class,
'new_payload' => ExamplePayload::class,
],
)]
readonly class BasePayload
{
public function __construct(
protected string $a,
) {
}
public function getA(): string
{
return $this->a;
}
#[Ignore]
public function isAString(): bool
{
return is_string($this->a);
}
}
<?php
declare(strict_types=1);
namespace App\Test;
final readonly class ExamplePayload extends BasePayload
{
public function __construct(
string $a,
protected string $b,
) {
parent::__construct($a);
}
public function getB(): string
{
return $this->b;
}
}
Runs this:
$serialized = $this->serializer->serialize($new BasePayload('string'), 'json');
get:
But then i drop Ignore attribute - it passes (but with unnecessary key "aString") !!
{"type":"base_payload","a":"string","aString":true}
How to reproduce
<?php
declare(strict_types=1);
namespace App\Test;
use Symfony\Component\Serializer\Attribute\DiscriminatorMap;
use Symfony\Component\Serializer\Attribute\Ignore;
#[DiscriminatorMap(
typeProperty: 'type',
mapping: [
'base_payload' => BasePayload::class,
'new_payload' => ExamplePayload::class,
],
)]
readonly class BasePayload
{
public function __construct(
protected string $a,
) {
}
public function getA(): string
{
return $this->a;
}
#[Ignore]
public function isAString(): bool
{
return is_string($this->a);
}
}
<?php
declare(strict_types=1);
namespace App\Test;
final readonly class ExamplePayload extends BasePayload
{
public function __construct(
string $a,
protected string $b,
) {
parent::__construct($a);
}
public function getB(): string
{
return $this->b;
}
}
$serialized = $this->serializer->serialize($new BasePayload('string'), 'json');
