Add symfony Validator Transformer

[leroy0211]

Symfony Validator component has a built in feature to normalize a ConstraintViolationListInterface to an RFC7807 output. However, you need to do this by returning this yourself like so:

# IndexController.php

public function index(ValidatorInterface $validator) 
{
     $errors = $validator->validate(...);
     return $this->json($errors, 400);
}

It would be much nicer to throw an exception, because in the above example, it is very easy to mis the response status. And with an exception it doesn't.

Maybe something like:

throw new ApiValidationException($errors);

Or does this package already has a solution for it?

Hello @leroy0211,

This one is already built-in in the main package: https://github.com/phpro/api-problem#validationapiproblem

new ValidationApiProblem($errors);

You can wrap and throw an ExceptionApiProblem or create your own ValidationFailedException and add a transformer for that one.
