ViewModel이 입력 필드를 채우지 않습니다.

Question

편집보기에 사용되는 ViewModel이 있습니다. 데이터가 반환되면 편집 할 항목의 ID가 편집 뷰에 표시되지 않습니다.

public ActionResult Edit(int id) 
{ 
    Parcel parcel = _parcelDao.GetParcel(id); 

    ParcelEditViewModel viewModel = new ParcelEditViewModel(); 

    viewModel.id = parcel.id; 
    return View(viewModel); 
} 

보기와 다른 것을 반환해야합니까?

뷰 모델 :

public class ParcelEditViewModel 
{ 

    public Parcel parcel { get; set; } 
    public int id { get; set; } 
    public IEnumerable<SelectListItem> TrackStatus { get; set; } 

    public ParcelEditViewModel() 
    { 
     parcel = new Parcel(); 

     TrackStatus = new List<SelectListItem> 
     { 
      new SelectListItem 
      { 
       Value = "AwaitingCollection", 
       Text = "Awaiting Collection" 
      }, 
      new SelectListItem 
      { 
       Value = "OutForDelivery", 
       Text = "Out For Delivery" 
      }, 
      new SelectListItem 
      { 
       Value = "Delivered", 
       Text = "Delivered" 
      } 

    }; 

    } 
    public int ParcelStatus { get; set; } 
}

Answer 1

; ID뿐만 아니라 ParcelEditViewModel에는 데이터베이스에있는 내용을 알지 못합니다. 이와을 간소화하는 데 도움이 될 수 있습니다 AutoMapper로 매핑 라이브러리가

public ActionResult Edit(int id) 
{ 
    Parcel parcel = _parcelDao.GetParcel(id); 
    ParcelEditViewModel viewModel = new ParcelEditViewModel(); 
    viewModel.id = parcel.id; 

    // Populate other properties! These may not be right. 
    viewModel.ProductName = parcel.Title; 
    viewModel.RecipientName; = parcel.RecipientName; 

    return View(viewModel); 
} 

있습니다.
