asp.net-mvc-4 - Automapper を使用してモデル MVC4 の選択したフィールドを編集する

Question

元のモデル (OApply) のビューモデル (OApplyIDViewModel) を使用して、選択したフィールドを更新しようとしています。実行しても変更は反映されません。これを経験した人からの助けに感謝します。エラーは発生しません。フォームが送信され、リダイレクトされます。

私はglobal.asaxでこれを持っています

   AutoMapper.Mapper.CreateMap<OApplyIDViewModel, OApply>();

これはビューモデルです

 public class OApplyIDViewModel
{
    [Key]
public int OAId { get; set; }

[Display(Name = "Identification")]
[Required(ErrorMessage = "Identification Required")]
public int IdId { get; set; }

[Display(Name = "Identification Number")][Required(ErrorMessage="ID Number Required")]
public string AIdentificationNo { get; set; }

[Display(Name = "Licence Version(5b)")]
[RequiredIf("IdId", Comparison.IsEqualTo, 1, ErrorMessage = "Version(5b) Required")]
public string ALicenceVersion { get; set; }

   public int CountryId { get; set; }
    [RequiredIf("IdId",Comparison.IsNotEqualTo,1, ErrorMessage="Country Required")]

    [Display(Name = "Your Electronic Signature Date Seal")]
    [Required(ErrorMessage="Date Signature Seal Required")]
    public DateTime SigDate { get; set; }
    [ScaffoldColumn(false)]
    [Display(Name = "Last Updated on")]
    public DateTime UDate { get; set; }
    [ScaffoldColumn(false)]
    [Display(Name = "Last Updated by")]
    public String UDateBy { get; set; }
    }

これはコントローラーにあります

//得る

     public ActionResult  ClientEditID(int id)
    {
     var model = new OApplyIDViewModel();
     OApply oapply  = db.OApply.Find(id);
    if (model == null )
     {

         return HttpNotFound();
     }
     ViewBag.CountryId = new SelectList(db.Countries, "CountryId", "CountryName", model.CountryId);
     ViewBag.IdId = new SelectList(db.PhotoIds, "IdId", "IdName",  model.IdId);
     return View();
      } 


[HttpPost]
   public ActionResult ClientEditId(OApplyIDViewModel oapply, int Id)
    {
   if (!ModelState.IsValid)
     {
    return View(oapply);
     }

    var onlineid = db.OApply.Where(x => x.OAId == Id).FirstOrDefault();
    Mapper.Map<OApplyIDViewModel,OApply>(oapply);
     oapply.UDateBy = Membership.GetUser().ProviderUserKey.ToString();
     oapply.UDate = DateTime.Now;
     db.Entry(onlineid).State= EntityState.Modified;
     db.SaveChanges();
     ViewBag.CountryId = new SelectList(db.Countries, "CountryId", "CountryName", oapply.CountryId);
     ViewBag.IdId = new SelectList(db.PhotoIds, "IdId", "IdName", oapply.IdId);
     return RedirectToAction("HomeAccount");

}

これがビューです

   @using (Html.BeginForm("ClientEditId", "OApply", FormMethod.Post, new { enctype = "multipart/form-data", @class = "stdform" }))
  {
    @Html.ValidationSummary(true)
      <fieldset>
    <legend>OnlineApplication</legend>
      @Html.HiddenFor(model => model.OAId)

    <div class="related">
    <div class="editor-label">
        @Html.LabelFor(model => model.IdId, "IdType")
    </div>
    <div class="editor-field">
        @Html.DropDownList("IdId", String.Empty)
        @Html.ValidationMessageFor(model => model.IdId)
    </div>
    <div class="editor-label">
        @Html.LabelFor(model => model.AIdentificationNo)
    </div>
    <div class="editor-field">

    <div class="country">

      <div class="editor-label">
