后端代码————

[Route("~/DesignDeliverable/Edit/{id?}")]
  [HttpGet]
  public ActionResult Edit(Guid? id) {
   using ( EmpsDbContext db = new EmpsDbContext() ) {
    DesignDeliverable entity = null;
    if ( id.HasValue ) {
     entity = db.DesignDeliverables.SingleOrDefault(x => x.Id == id.Value);
    }
    else {
     entity = new DesignDeliverable();
    }
    ViewBag.Rooms = RoomFacade.GetAll().Select(x => new SelectListItem { Text = x.Name, Value = x.Id.ToString() }).ToList();
    ViewBag.Areas = AreaFacade.GetAll().Select(x => new SelectListItem { Text = x.Name, Value = x.Id.ToString() }).ToList();
    return View(entity);
   }
  }
  [Route("~/DesignDeliverable/Save")]
  [HttpPost]
  public JsonResult Edit(DesignDeliverable model) {
   using ( EmpsDbContext db = new EmpsDbContext() ) {
    if ( !ModelState.IsValid ) {
     return Error();
    }
    try {
     model.GroupId = new Guid("e030c300-849c-4def-807e-a5b35cf144a8"); //todo: fix this hardcode
     db.DesignDeliverables.AddOrUpdate(model);
     db.SaveChanges();
     return Success();
    }
    catch {
     //TODO: to store the exception message
    }
    return Error();
   }
  }
