Description

I use the MoneyType with the scale option set to 4.

The property is a string, using the decimal Doctrine type. And the setter on the entity accepts a string as argument.

When submitting the form & saving the entity into the database, there's always an update of the entity, even if the value has not changed (it's rounding e.g. 0.0000 to 0).

I noticed the issue disappears if I use the same form configuration, but using the NumberType instead, with the input option set to string. However, the input option of the MoneyType does not accept the string value.

I currently fixed the issue with a form extension:

<?php

declare(strict_types=1);

namespace App\Form\Extension;

use Symfony\Component\Form\AbstractTypeExtension;
use Symfony\Component\Form\Extension\Core\DataTransformer\StringToFloatTransformer;
use Symfony\Component\Form\Extension\Core\Type\MoneyType;
use Symfony\Component\Form\FormBuilderInterface;

final class MoneyTypeExtension extends AbstractTypeExtension
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder->addModelTransformer(new StringToFloatTransformer($options['scale']));
    }

    public static function getExtendedTypes(): iterable
    {
        return [MoneyType::class];
    }
}

But I think it would be better to allow string for the input option like the NumberType does?
