편집 동작으로 ViewModel 오류 편집

Question

편집 viewmodel을 작동 시키려고합니다. [httpget]에서는 문제가 없지만 [httppost]에서는 데이터베이스에 저장/업데이트되지 않습니다. 그것은 나를 내 http 오류 404.0로 보냅니다 - 찾을 수 없습니다. 내 축제 컨트롤러에서

편집 작업 : :

[HttpGet] 
    public ActionResult Edit2(int? id) 
    { 
     //Festival fest = db.Festivals.Include("County").Include("FestivalType").Include("Towns").Where(x => x.FestivalId == id).Single(); 
     Festival fest = db.Festivals.Where(x => x.FestivalId == id).FirstOrDefault(); 

     FestivalVM festival = new FestivalVM { SelectedCounty = fest.FestivalCounty.ID, endDate = fest.EndDate, FestivalName = fest.FestivalName, SelectedFestivalType = fest.FType.ID, startDate = fest.StartDate, SelectedTown = fest.FestivalTown.ID }; 
     if (fest != null) 
     { 

      festival.County = db.Counties.ToDictionary(p => p.ID, q => q.Name); 
      festival.FestivalType = db.FestivalTypes.ToDictionary(p => p.ID, q => q.FType); 
      festival.FestivalType.Add(-1, "----- Add New Festival Type -----"); 
      festival.Towns = db.Towns.ToDictionary(p => p.ID, q => q.Name); 

      festival.startDate = (from f in db.Festivals where fest.FestivalId == id select f.StartDate).FirstOrDefault(); 

      festival.endDate = (from f in db.Festivals where fest.FestivalId == id select f.EndDate).FirstOrDefault(); 

      return View(festival); 
     } 
     return HttpNotFound(); 
    } 

    [HttpPost] 
    public ActionResult Edit2(FestivalVM model) 
    { 
     if (ModelState.IsValid != true) 
     { 
      if (model.SelectedFestivalType != -1)

       return RedirectToAction("Details", "Festival", new { id = f.FestivalId });

      } 
      ModelState.AddModelError("", "No Festival Type Picked"); 
     } 
     model.County = db.Counties.ToDictionary(p => p.ID, q => q.Name);

) (변경 사항이 db.SaveChanges를 호출하기 전에이 줄을 추가 저장하려면 여기

내 코드입니다 :

db.Festival.Add(f); 

컨텍스트에 추가하지 않습니다.
