[RFC] HAL implementation of "curies" link for PaginatedRepresentation

[instabledesign]

Have "curies" link on PaginetedRepresentation like this

{
  "page": 1,
  "limit": 20,
  "pages": 1,
  "total": 1,
  "_links": {
    "self": {
      "href": "/app_dev.php/api/foo/1/bar?page=1&limit=20"
    },
    "first": {
      "href": "/app_dev.php/api/foo/1/bar?page=1&limit=20"
    },
    "last": {
      "href": "/app_dev.php/api/foo/1/bar?page=1&limit=20"
    },
    "curies": [
      {
        "href": "/api/foo/{foo}/bar",
        "name": "api_get_foo_bar",
        "templated": "true"
      }
    ]
  },
  "_embedded": {
    "items": [
      {
        "id": 2,
        "title": "test",
        "_links": {
          "self": {
            "href": "/app_dev.php/api/bar/2"
          }
        }
      }
    ]
  }
}

For the moment i have implemented with annotation like this

<?php

namespace Instable\PhotoBundle\Representation;

use Hateoas\Representation\PaginatedRepresentation;
use Hateoas\Configuration\Annotation as Hateoas;

/**
 * Class PaginatedRepresentationWithCuries
 *
 * @Hateoas\Relation(
 *      "curies",
 *      attributes = {
 *          "name" = "expr(object.getRoute())",
 *          "templated" = "true"
 *      },
 *      href = "expr(service('router').getRouteCollection().get(object.getRoute()).getPath())",
 *      exclusion = @Hateoas\Exclusion(
 *          excludeIf = "expr(object.getRoute() === null)"
 *      )
 * )
 */
class PaginatedRepresentationWithCuries extends PaginatedRepresentation
{
}

Its an RFC because i don't know if it's the best way to implement it. (Don't know about efficiency of "expr(service('router'))")

An another way to implement it is to have the Symfony\Component\Routing::$path in Hateoas\Configuration\Route and pass it to the Hateoas\Representation\PaginatedRepresentation::__construct() but this constructor already have 10 arguments

@instabledesign Have you solved your problem? Any follow-ups? I created a CurieExtension (ConfigurationExtensionInterface) that does more-or-less what you described.

Hi, ~~I dont remember because this issue was old. But i think i was solved in a different way.~~

I just re read and the answer was in the question :) I extend PaginatedRepresentation to add annotation and used expression language to do the job...

thanks
