Ошибка при добавлении записей с использованием Javascript Entity Framework C # MVC Json

Question

У меня проблема с добавлением записи, содержащейся в данных.

Внутреннее исключение:

Неверное имя столбца 'CustomerNames_CustomerId'.Неверное имя столбца 'CustomerNames_CustomerId'.Неверное имя столбца 'CustomerNames_CustomerId'.

Я не могу понять это, поскольку в CustomerNames есть столбец CustomerId.Все работает (добавление товаров в корзину, получение CustomerId), кроме тех случаев, когда вы сохраняете заказ.

То есть, когда я получаю ошибку в строке, у меня разрыв.

Действия контроллера (PartsController) :

 public ActionResult PartsDetail(int id, string mReq)
    {
        Session["CustomerId"] = id;

        if (mReq == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        SubJobDetails modelInstance = SubJobDetails.GetSubjobsAndParts(mReq, db);
        //if (modelInstance == null)
        //{
        //    return HttpNotFound();
        //}
        return View(modelInstance);
    }

    public static List<SubJobDetails> partsList = new List<SubJobDetails>();

    [HttpPost]
    public ActionResult AddToShoppingCart(SubJobDetails parts)
    {
        string message = string.Empty;

        if (parts != null)
        {
            partsList.Add(parts);
            message = "product has been added successfully !";
        }
        else
        {
            message = "something Wrong  !";
        }

        return Json(new { message = message }, JsonRequestBehavior.AllowGet);
    }
