The BitExpert blog has a post sharing some of author Stephan Hochdörfer's experience in combining Doctrine and the ramsey/uuid-doctrine and willdurand/hateoas packages to create a system that follows the HATEOAS API documentation structure for his Doctrine-based objects.
Recently I experimented a bit with Doctrine ORM and the willdurand/Hateoas library to expose my Doctrine objects via an HATEOAS api which luckily is a fairly trivial thing to do. All you need to do is set up the Hateoas serializer and call the respective serialize() method passing your Doctrine object as well the serialization type.
He shares the code to make the integration work, pointing out that the ramsey/uuid-doctrine library makes masking the autoincrement database identifiers (their "id" column) with UUIDs easier. He shows how to integrate this Uuid data type into the Doctrine docblock configuration and how to use the
HateoasBuilder to handle the serializer instance containing the Doctrine object/results.
