MVC'de Görüntüleme/Oluşturma işlevi nasıl eklenir ve dizine güncellenir?

Question

Hala MVC'ye yeni geliyorum ama bunu gerçekten merak ediyorum. Create view işlevim var, ama neden indeksime geri oluşturduğum yeni verileri gösteremediğimi merak ediyordum? Burada

benim denetleyicisi geçerli:

 //GET /UserActivity/Create 
    public ActionResult Create() 
    { 
     UserActivityModels ua = new UserActivityModels(); 
     return View(userActivity); 
    } 


    // 
    // POST: /UserActivity/Create 
    [HttpPost] 
    public ActionResult Create(FormCollection formCollection) 
    { 
     try 
     { 
      UserActivityModels ua = new UserActivityModels(); 


      ua.Id = Int32.Parse(formCollection["Id"]); 
      ua.CreatedBy = Int32.Parse(formCollection["CreatedBy"]); 
      ua.CreatedOn = DateTime.Parse(formCollection["CreatedOn"]); 
      ua.ModifiedBy = Int32.Parse(formCollection["ModifiedBy"]); 
      ua.ModifiedOn = DateTime.Parse(formCollection["ModifiedOn"]); 
      ua.ContactId = formCollection["ContactId"]; 
      ua.StatusCode = Int32.Parse(formCollection["StatusCode"]); 
      ua.StateCode = Int32.Parse(formCollection["StateCode"]); 
      ua.EntityName = formCollection["EntityName"]; 
      ua.EntityId = Int32.Parse(formCollection["EntityId"]); 
      ua.ActivityType = Int32.Parse(formCollection["ActivityType"]); 
      ua.ActivityStatus = formCollection["ActivityStatus"]; 

      ua.DueDate = DateTime.Parse(formCollection["DueDate"]); 

      ua.ActualEndDate = DateTime.Parse(formCollection["ActualEndDate"]); 

      ua.MasqueradeOn = DateTime.Parse(formCollection["MasqueradeOn"]); 

      ua.MasqueradeBy = Int32.Parse(formCollection["MasqueradeBy"]); 


      return RedirectToAction("Index"); 
     } 

     catch 
     { 
      return View("Index"); 
     } 
    } 

modeli:

public class UserActivityModels 
{ 
    public int Id { get; set; } 

    public DateTime CreatedOn { get; set; } 

    public int CreatedBy { get; set; } 

    public int ModifiedBy { get; set; } 

    public DateTime ModifiedOn { get; set; } 

    public string ContactId { get; set; } 

    public string EntityName { get; set; } 

    public int EntityId { get; set; } 

    public int StatusCode { get; set; } 

    public int StateCode { get; set; } 

    public int ActivityType { get; set; } 

    public string ActivityStatus { get; set; } 

    public DateTime DueDate { get; set; } 

    public DateTime ActualEndDate { get; set; } 

    public DateTime MasqueradeOn { get; set; } 

    public int MasqueradeBy { get; set; } 

    public string ContactName { get; set; } 

    //public int TotalCount { get; set; } 

    // public List<string> userActivity { get; set; } 

} 

ben tıklayın "Gönder" butonuna zaman, yeni oluşturulan veri şimdi dizinde gösteriyor neden

kimse bana söyleyebilirdi mu ? senin Index yöntemle İçinde

    ViewBag.Title = "Index";

Answer 1

, size Create yöntemde oluşturulan modeli almak zorunda ve bağımsız değişken olduğu gibi o kullanır: Burada

ve teşekkür

Görünüm/Endeksi ise görünümü döndürüyor.

Bir denetleyici yönteminden diğerine bir model geçirmenin bir yolu, TempData sözlüğünü kullanmaktır.

Peki yapabileceğiniz şudur: sizin Create yöntemde, sadece return RedirectToAction("Index"); çağırmadan önce, TempData modelinizi saklamak: Index yöntemde, Sonra

TempData["MyModel"] = ua; 

TempData gelen modeli almak ve geçmek görünüm:

var myModel = (UserActivityModels)TempData["MyModel"]; 

return View(myModel);
