Provides a method to validate an entity.

Namespace

Code

protected static function validate(EntityInterface $entity, array $field_names = NULL) {
    if (!$entity instanceof FieldableEntityInterface) {
        return;
    }
    $violations = $entity->validate();

    // changes.
    $violations->filterByFieldAccess();
    // Filter violations based on the given fields.
    if ($field_names !== NULL) {
        $violations->filterByFields(array_diff(array_keys($entity->getFieldDefinitions()), $field_names));
    }
    if (count($violations) > 0) {
        // Instead of returning a generic 400 response we use the more specific
        // 422 Unprocessable Entity code from RFC 4918. That way clients can
        // distinguish between general syntax errors in bad serializations (code
        // 400) and semantic errors in well-formed requests (code 422).
        // @see \Drupal\jsonapi\Normalizer\UnprocessableHttpEntityExceptionNormalizer
        $exception = new UnprocessableHttpEntityException();
        $exception->setViolations($violations);
        throw $exception;
