How to use (chain?) multiple normalizers with Symfony Serializer?
You have to use the NormalizerAwareTrait so you can access the normalizer for books
- add interface
- use trait
- call normalize() method for books
code:
class UserNormalizer implements NormalizerInterface, NormalizerAwareInterface{ use NormalizerAwareTrait; public function normalize($object, $format = null, array $context = array()) { return [ 'name' => $object->getName(), 'books' => $this->normalizer->normalize($object->getBooks(), $format, $context) ]; } public function supportsNormalization($data, $format = null) { return $data instanceof User; }}
