unsubmitted form doesn't get violation mapped #30011
Description
I am not sure if this is a bug, but the behavior looks strange.
CarBrandType
class CarBrandType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('name', FormTypes\TextType::class, [
'label' => 'acme.car_brand.name.label',
'required' => true,
])
->add('enabled', FormTypes\CheckboxType::class, [
'label' => 'acme.car_brand.enabled.label',
'required' => false,
])
->add('image', FormTypes\TextType::class, [
'label' => 'acme.car_brand.image.label',
'required' => false,
]);
}
}
violation rules
Acme\Bundle\AutoBundle\Entity\CarBrand:
properties:
name:
- NotBlank: { groups: ['acme'] }
- Length: { groups: ['acme'] , max: 40}
Test
I submitted data without the required field name, I can see a violation happened at Symfony\Component\Form\Extension\Validator\EventListener\ValidationListener class, however, calling $form->isValid() will return true, because the Symfony\Component\Form\Extension\Validator\ViolationMapper\ViolationMapper doesn't map violation to unsubmitted form. that is the isValid method is not 100% sure the form has no violations. what is the sure way?
