how to use @RelationProvider

[TOTOleHero]

Hello,

I don't understand how to use the annotation @RelationProvider. The current object is never available on all methods (exp(), object::static() or func() )

How to get the current object to iterate on elements from his method ?

example :

namespace App\Entity;

/*
* @Hateoas\Relation( ??? ... object.getOtherObjects() ... ??? )
*/
class MyObject
{

    /**
     * @ORM\ManyToMany(targetEntity=MyOtherObject::class, inversedBy="myObjects")
     */
    private $otherObject;

...
    public function getOtherObjects()
    {
        return $this->otherObject;
    }
...

}


class MyObject
{

...
     public function getId()
    {
        return $this->id;
    }
...
}

To generate ...

{
  "_links": {
    "otherObjects": [
      {"href": "/api/otherObject/1"},
      {"href": "/api/otherObject/6"},
      {"href": "/api/otherObject/78"}
    ]
  }
}

thank's you

Hi @TOTOleHero,

I've got the exact same question. As far as I understand the RelationProvider construct, it's not meant to provide Relations in realtime, but provide a single place where you can provide parsed Relation (expressions) which then can be cached.

I did not read the code to the end, but I guess all a RelationProvider does is providing a collection of cachable Relation metadata from one place.

However I think you use case should be adressed with @Embedded.

Please, someone correct me if I'm wrong.
