Description

Hello there !

As I was pretty hyped to use DatePoint for my new entities, I made one, built a form, but encountered something wrong on form submitting : a DateTime instance was given to my DatePoint property.

I then figured out that there is no DatePointType to support converting the chosen DateTime to a DatePoint instance. In order to get this working, I had to create a very simple FormType with a ModelTransformer that would reverse transform the DateTime into a DatePoint instance. However, I think this could be integrated to Symfony, because it feels incomplete right now.

The only concern I thought about is : difference between Date and DateTime. Should we have both DatePointType and DateTimePointType ? I don't know.

Waiting to here from you guys.

Thanks !

Example

$builder->add('date', DatePointType::class);

class DatePointType extends AbstractType
{
    public function __construct(
        private readonly DatePointModelTransformer $modelTransformer,
    ) {}

    public function getParent(): string
    {
        return DateTimeType::class;
    }

    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder->addModelTransformer($this->modelTransformer);
    }
}

final readonly class DatePointModelTransformer implement DataTransformerInterface
{
    public function transform(mixed $value): string
    {
        return $value;
    }

    public function reverseTransform(mixed $value): ?DatePoint
    {
        if (null === $value) {
            return null;
        }

        return DatePoint::createFromInterface($value);
    }
}

Just wrote the code on Github from memory, sorry it is incorrect
