ManyToMany self referencing and exceeded number of join relations exception

Hi,

First of all, big thanks for api-platform it’s amazing.

I have the Campaign resource:

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;

/**
 * A campaign.
 *
 * @ORM\Entity()
 */
class Campaign
{
    /**
     * @Groups({"campaign_list", "campaign_get"})
     *
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @Groups({"campaign_list", "campaign_get"})
     *
     * @ORM\Column
     */
    private $name;

    /**
     * @Groups({"campaign_get"})
     *
     * @ORM\ManyToMany(targetEntity="AppBundle\Entity\Campaign")
     */
    private $excluded;
}

When I try to GET /campaigns I get this exception:

The total number of joined relations has exceeded the specified maximum. Raise the limit if necessary.

Indeed, you have a recursive relation here, where campaign is referencing itself. You may want to disable eager loading here by using @ApiResource(attributes={"force_eager"=false}).

@clementtalleu I didn’t have to change enythink, becasue @Simperfit pull request resolves my issue, which version of api platform do you have?
