Digging deeper into #1528, I think that this should be handled at the Symfony level, so I proposed symfony/symfony#26108

I would like to revert #1528 before releasing the stable release.

ping @api-platform/core-team @adelplace

👍 we will document the proper way of handling this if we can get symfony/symfony#26108 merged! Btw you can add a 👍 to show your interest in that PR!

I think that this should be handled at the Symfony level

Yes I totally agree

[silverbackdan]

Is there any chance on how to implement this functionality with the PR now merged in Symfony?

Is it worth API Platform having a built-in handler that can be enabled with annotation on specific properties?

[soyuka]

@silverbackdan just set this in symfony configuration:

serializer:
  max_depth_handler: App\MaxDepthHandler

Your service would look like this:

<?php
namespace App;

class MaxDepthHandler
{
  public function __invoke($obj) {
    return $obj->id; // or whatever
  }
}

Thanks @soyuka - so very simple :)
