使用視圖模型進行遠程驗證。 列出視圖模型中的屬性
[英]Remote validation with viewmodels. List properties in viewmodel
問題描述
我正在嘗試對預訂 web 應用程序中的某些屬性進行遠程驗證。
public class ReservationVM
{
public Rsvn ReservationInfo { get; set; } // Model for Reservation
public AdminFilterRsvn FilterAdmin { get; set; } // Model for Filter in Admin Panel ???
public IEnumerable<Rsvn> ReservationQuery { get; set; } // Query of All Reservations in Database
public IEnumerable<AvailableRooms> AvailableRooms { get; set; } // Query of All Free and Reserved Rooms SearchResult View
public List<Room> RoomList { get; set; } // List of Rooms
public List<Guest> GuestList { get; set; } // List of Guests
}
該虛擬機的視圖是：

我正在嘗試進行的驗證是在訪客模式下進行的，即：
public class Guest
{
public int? GusetID { get; set; }
public string ReservationID { get; set; }
[Required(ErrorMessage = "Въведете име")]
public string FirstName { get; set; }
public string LastName { get; set; }
[Required(ErrorMessage = "Въведете семейно име")]
public string FamilyName { get; set; }
public string PhoneNumber { get; set; }
[EnumDataType(typeof(PersonType), ErrorMessage = "Въведете тип гост")]
public PersonType PersonType { get; set; }
[EnumDataType(typeof(PersonAge), ErrorMessage = "Въведете възраст")]
public PersonAge PersonAge { get; set; }
[EnumDataType(typeof(Gender), ErrorMessage = "Въведете пол")]
public Gender Gender { get; set; }
[Required(ErrorMessage = "Полето ЕГН не може да бъде празно")]
[Remote("IsCorrectEGN", "Reservation", HttpMethod ="POST", ErrorMessage = "Въведете правилно ЕГН.")]
public string EGN { get; set; }
[Required(ErrorMessage = "Въведете дата на раждане")]
public DateTime? BirthDate { get; set; }
[Required(ErrorMessage ="Въведете номер на стая")]
[Remote("CheckPersonAge", "Reservation", HttpMethod ="POST", ErrorMessage = "Възраста която въведохте, не съответсва с тип гост.")]
public int? GuestRoomID { get; set; }
public char? IsMainGuest { get; set; }
public string PersonTypeDescription { get; set; }
public string PersonAgeDescription { get; set; }
public string PersonGenderDescription { get; set; }
public IEnumerable<SelectListItem> PersonTypeList { get; set; }
public IEnumerable<SelectListItem> PersonAgeList { get; set; }
public IEnumerable<SelectListItem> PersonGenderList { get; set; }
public IEnumerable<SelectListItem> GuestRoomIDList { get; set; }
}
驗證碼在 ReservationController 中：
public JsonResult IsCorrectEGN(ReservationVM Reservation)
{
Reservation
string EGN = null;
string[] ListEGN = new string[Reservation.GuestList.Count];
for (int index = 0; index < Reservation.GuestList.Count; index++)
{
EGN = Reservation.GuestList[index].EGN;
//ListEGN[index] = Reservation.GuestList[index].EGN;
}
return Json(CheckEGN(EGN), JsonRequestBehavior.AllowGet);
}
public bool CheckEGN(string EGN)
{
DbManager db = new DbManager();
int result = db.CheckIfEGNISValid(EGN);
bool isValidEgn = false;
if (result == 1)
isValidEgn = true;
return isValidEgn;
}
CheckEGN(param) 正在調用 db 方法，該方法將 EGN 發送到 Oracle DB，如果正常則返回 1，如果錯誤則返回 0。 數據庫方法如下：
public int CheckIfEGNISValid(string egn)
{
OracleCommand cmd = new OracleCommand("", GetDBConnection());
cmd.CommandType = CommandType.Text;
cmd.BindByName = true;
OracleParameter ret = new OracleParameter();
ret.Direction = ParameterDirection.ReturnValue;
cmd.Parameters.Add(ret);
cmd.CommandText = @"select s_checks.is_EGN(:str_inp) from dual";
cmd.Parameters.Add(GetStringParameter(egn, "str_inp"));
//cmd.Parameters.Add(GetNotNullableDateParameter(begDate, "p_beg_date"));
//cmd.Parameters.Add(GetNotNullableDateParameter(endDate, "p_end_date"));
//cmd.ExecuteNonQuery();
ret.Value = cmd.ExecuteScalar();
closeDBConnection();
var result = Convert.ToInt32(ret.Value.ToString());
return result;
}
如果我處理簡單數據，我知道遠程驗證的概念是 MVC。 我所說的簡單數據不是列表等。這里的事情是我可以有 X 位客人，我需要檢查他們是否輸入了有效的 PersonID(EGN)。 到目前為止，我的代碼僅適用於第一位客人。 對於第 2 個、第 3 個...第 N 個，ReservationVM 是 null。因此沒有數據從視圖傳遞到 controller 和 AJAX。
我如何進行驗證以檢查每位客人。 我願意接受任何建議。 我還是 ASP.NET 的新手，還有很多東西要學。
所以這就是列表中第一項發生的情況，首先 EGN 到達 controller 1
第二個： 2

我想你忘了在view中添加這些腳本
