Validation for uniqueness?

Question

symfony

Doesn't fit, because it needs to be written in the entity.
And it is necessary to validate the data even before the entity is.

$constraint = new Assert(
                [
                    'email' => [
                        new UniqueEntity(
                            [
                                'fields'      => 'email',
                                'errorPath'   => 'email',
                                'entityClass' => User::class,
                                //'em'  => 'some service id',
                                //'repositoryMethod'  => 'findBy',
                                'message'     => 'Not unique email'
                            ]
                        ),

Apparently you need to write your own validator, right?

Yes, and by the way, it's quite convenient.
