Проект состоит из четырех связанных таблиц:

1. orders (id, status, client_email, partner_id)
2. order_products (id, order_id, product_id, quantity, price)
3. partners (id, email, name)
4. prods* (id, name, price, vendor_id)
*таблица products есть и используется под другие функции, поэтому использую здесь "prods"

создаю 4 модели:

<?php
    //App\Order.php
    namespace App;
    use Illuminate\Database\Eloquent\Model;

    class Order extends Model
    {
        protected $fillable = [
      'id',  'status', 'client_email', 'partner_id',
    ];

public function partner()
  {
    return $this->belongsTo('App\Partner');
  }

public function order_product()
  {
//belongsToMany - возвращает server error
    return $this->belongsTo('App\Prod', 'order_products');
  }

public function prod()
  {
    return $this->belongsTo('App\Prod');
  }

    }

<?php
//App\Partner.php
namespace App;
use Illuminate\Database\Eloquent\Model;

class Partner extends Model
{
   protected $fillable = ['id', 'email', 'name'];

public function order()
  {
    return $this->hasOne('App\Order');
  }
}

 <?php
    //App\Order_product.php
    namespace App;
    use Illuminate\Database\Eloquent\Model;

    class Order_product extends Model
    {
        protected $fillable = ['order_id', 'product_id', 'quantity', 'price'];

 public function order()
  {
    return $this->hasOne('App\Order');
  }

    }

<?php
    //App\Prod.php
    namespace App;
    use Illuminate\Database\Eloquent\Model;

    class Prod extends Model
    {
        protected $fillable = ['order_id', 'product_id', 'quantity', 'price'];

    public function order()
  {
    return $this->belongsToMany('App\Order', 'order_products');
  }

    }

Далее создаю Order Resources:

<?php
//App\Http\Resources\Order.php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;

class Order extends JsonResource
{
    public function toArray($request)
{
    return [
        'id'           => $this->id,
        'status'       => $this->status,
        'client_email' => $this->client_email,
        'partner_id'   => $this->partner_id,
        'partner_name' => $this->partner->name,

        //возвращает server error
        'product_id'   => Prod::collection($this->order_product), 
        'name'         => $this->prod->name,

    ];
}
}

создаю Prod Resource:

<?php
//App/Http/Resources\Prode.php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;

class Prod extends JsonResource
{
    public function toArray($request)
    {
        return [
            'id'      => $this->id,
            'name'    => $this->name,
            'price'   => $this->price,
        ];
    }
}

И возвращаю из Order Controller:

<?php
//App\Http\Controllers\Api\OrderController.php
namespace App\Http\Controllers\Api;

use App\Order;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Http\Resources\Order as OrderResource;

class OrderController extends Controller
{
public function index()
  {
    $orders = Order::with(['partner', 'order_product', 'prod'])->get();
    return OrderResource::collection($orders);
   }
}

Как я могу получить название продукта в заказе?
