Is there any reason to set the context attribute as final?
My proposal is to remove the final statement, allowing us to create custom context attributes. Our use-case is typically adding a callback for any object property implementing the attribute. But I can see many other use-case, like simplifying the context attribute when it becomes huge or repeated a lot of time like this:
class MyObject
{
#[Context(
normalizationContext: [
AbstractNormalizer::ATTRIBUTES => [MyCustomNormalizer::class],
AbstractObjectNormalizer::ENABLE_MAX_DEPTH => true,
AbstractObjectNormalizer::SKIP_NULL_VALUES => true,
],
denormalizationContext: [
AbstractNormalizer::ATTRIBUTES => [MyOtherCustomNormalizer::class],
AbstractObjectNormalizer::ENABLE_MAX_DEPTH => false,
AbstractObjectNormalizer::SKIP_NULL_VALUES => false,
],
groups: ['group1', 'group2'],
)]
private ?MyOtherObject $otherObject = null;
#[Context(
normalizationContext: [
AbstractNormalizer::ATTRIBUTES => [MyCustomNormalizer::class],
AbstractObjectNormalizer::ENABLE_MAX_DEPTH => true,
AbstractObjectNormalizer::SKIP_NULL_VALUES => true,
],
denormalizationContext: [
AbstractNormalizer::ATTRIBUTES => [MyOtherCustomNormalizer::class],
AbstractObjectNormalizer::ENABLE_MAX_DEPTH => false,
AbstractObjectNormalizer::SKIP_NULL_VALUES => false,
],
groups: ['group1', 'group2'],
)]
private ?MyOtherObject $otherObject2 = null;
}Example
Another example is when you want to normalize as you wish your objects.
#[\Attribute(\Attribute::TARGET_PROPERTY|\Attribute::TARGET_METHOD|\Attribute::IS_REPEATABLE)]
class FloatAsString extends Context
{
public function __construct()
{
parent::__construct(
normalizationContext: [
AbstractNormalizer::CALLBACKS => [
'floatProperty' => fn (float $value): string => (string) $value,
],
],
denormalizationContext: [
AbstractNormalizer::CALLBACKS => [
'floatProperty' => fn (string $value): float => (float) $value,
],
],
);
}
}class MyObject
{
#[FloatAsString]
private ?MyOtherObject $otherObject = null;
}Thank you!
