这是我的视图模型:
public class UpdateReservationVM
{
public virtual Reservation Reservation { get; set; }
public virtual Payment Payment { get; set; }
public virtual FlightInfo Flight { get; set; }
public virtual RoomReservation Room { get; set; }
public virtual Transfer Transfer { get; set; }
}
这个代码有什么问题?试图调试它时,它总是转到控制器的action方法,但传递的值都是NULL 试试
[HttpPost]
public ActionResult Update(ViewModels.UpdateReservationVM reservation)
{
if (ModelState.IsValid)
{
db.Reservation.Attach(UpdateReservationVM.reservation);
db.Entry(UpdateReservationVM.reservation).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(reservation);
}
调试时,请检查保留(小写)是否不为null
另一方面,您可能需要更改
public ActionResult Update(ViewModels.UpdateReservationVM reservation)
到
并在控制器顶部添加using语句,以包括viewmodel命名空间
using YOURPROJECTNAME.NAMEOFVIEWMODELSFOLDER;
所以,在我的情况下
using salesWebsite.viewModel;
在您的表单中添加antiforgerytoken:
@using (Html.BeginForm("Update", "Reservations", FormMethod.Post, new { @class = "form-horizontal" }))
{
@Html.AntiForgeryToken()
@*
rest of code
*@
}
修改了我的问题,@DLeh well付款、航班、房间和转机在我提交form@LuigiVibal-如果执行此操作,还需要在控制器中[HttpPost]的正下方添加[ValidateAntiForgeryToken]。@tintyethan仍然不工作您是否按照我在上面的完整回复中所说的做了?添加antiforgerytoken是一种很好的做法,但我认为它与空表单值无关。
using salesWebsite.viewModel;
@using (Html.BeginForm("Update", "Reservations", FormMethod.Post, new { @class = "form-horizontal" }))
{
@Html.AntiForgeryToken()
@*
rest of code
*@
}
