Символьная ссылка MongoDB ObjectID на атрибут Mysql mongoId (FK)

Question

Невозможность сохранения автоматически сгенерированного идентификатора объекта MongoDB в атрибут таблицы mysql mongo_id (FK)

Я уже использовал https://github.com/jenssegers/laravel-mongodb, проверил связь между mysql ORM и MongoDB ODM / ORM, используя tinker и HybridRelations Trait из пакета, но не могу автоматически сгенерировать самогенерируемый MongoDB ObjectID с атрибутом таблицы mysql mongo_id используется в качестве внешнего ключа. Я должен вручную скопировать этот идентификатор объекта в таблицу mysql, чтобы проверить отношение / связь между mysql и mongodb ORM / ODM. Как мне решить эту проблему?

DCSurvey (Mysql):

<?php

namespace App\Models\Modules\DataCollection\Organisation;

use Illuminate\Database\Eloquent\Model;
use Jenssegers\Mongodb\Eloquent\HybridRelations;

class DCSurvey extends Model
{
    use HybridRelations;

    protected $connection = 'mysql';

    protected $table = 'd_c_surveys';

    protected $fillable=['user_id','country','lang','title','category','start_date','end_date','status','istemplate','isprivate','istemporary','points','mongo_id','deleted_at'];

    public function mongosurvey(){
        return $this->hasOne('App\Models\Modules\DataCollection\MongoDB\MongoSurvey','_id','mongo_id');
    }
}

MongoSurvey (MongoDB):

<?php

namespace App\Models\Modules\DataCollection\MongoDB;

use Jenssegers\Mongodb\Eloquent\Model as Eloquent;

class MongoSurvey extends Eloquent
{
    protected $connection = 'mongodb';

    protected $collection = 'mongo_surveys';

    protected $casts = [
        '_id' => 'binary',
    ];

    public function dcsurvey(){
        return $this->belongsTo('App\Models\Modules\DataCollection\Organisation\DCSurvey','mongo_id');
    }
}

Было бы очень полезно, если бы кто-то мог разобраться с этой проблемой. Заранее спасибо.
