錯誤與編輯用戶[ASP MVC]

Question

我有修改用戶信息，當我嘗試編輯暱稱或電子郵件地址或電話號碼，然後點擊保存，什麼都沒有改變一個問題....

這裏是我的賬戶控制器方法：

[Authorize] 
    [HttpPost] 
    // POST: /Account/Edit_Info 

    public ActionResult Edit_Info(UserVm model) 
    { 
     var id = User.Identity.GetUserId(); 

     if (ModelState.IsValid) 
     { 
      var User_Model = db.AspNetUsers.Find(id); 
      User_Model.NickName = model.User.NickName; 
      User_Model.Email = model.User.Email; 
      User_Model.PhoneNumber = model.User.PhoneNumber; 
      db.Entry(User_Model).State = EntityState.Modified; 
      db.SaveChanges(); 
      return RedirectToAction("Index"); 
     } 
     return RedirectToAction("Index"); 

    } 

這是我的觀點：

@using (Html.BeginForm("Edit_Info", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" })) 
            { 
            @Html.AntiForgeryToken() 

            <div class="form-horizontal"> 
             <h4>Personal Information</h4> 
             <hr /> 
             @Html.ValidationSummary(true, "", new { @class = "text-danger" }) 
             @Html.HiddenFor(model => model.User.Id) 

             <div class="form-group"> 
              @Html.LabelFor(model => model.User.NickName, htmlAttributes: new { @class = "control-label col-md-2" }) 
              <div class="col-md-10"> 
               @Html.EditorFor(model => model.User.NickName, new { htmlAttributes = new { @class = "form-control" } }) 
               @Html.ValidationMessageFor(model => model.User.NickName, "", new { @class = "text-danger" }) 
              </div> 
             </div> 
             <div class="form-group"> 
              @Html.LabelFor(model => model.User.Email, htmlAttributes: new { @class = "control-label col-md-2" }) 
              <div class="col-md-10"> 
               @Html.EditorFor(model => model.User.Email, new { htmlAttributes = new { @class = "form-control" } }) 
               @Html.ValidationMessageFor(model => model.User.Email, "", new { @class = "text-danger" }) 
              </div> 
             </div> 
             <div class="form-group"> 
              @Html.LabelFor(model => model.User.PhoneNumber, htmlAttributes: new { @class = "control-label col-md-2" }) 
              <div class="col-md-10"> 
               @Html.EditorFor(model => model.User.PhoneNumber, new { htmlAttributes = new { @class = "form-control" } }) 
               @Html.ValidationMessageFor(model => model.User.PhoneNumber, "", new { @class = "text-danger" }) 
              </div> 
             </div> 


             <div class="form-group"> 
              <div class="col-md-offset-2 col-md-10"> 
               <input type="submit" value="Save" class="btn green" /> 
              </div> 
             </div> 
            </div> 
            } 

這裏是我的ViewModel：

public class UserVm 
{ 

    public List<Book> Books { set; get; } 
    public AspNetUser User { set; get; } 
    public List<ReadLater> ReadLaters { set; get; } 
    public List<Favourite> Favourites { set; get; } 
    public ChangePasswordViewModel ChangePasswordViewModel { set; get; } 

} 

誰能幫我找到這個問題，並感謝

解決這個（感謝@斯蒂芬 - Muecke）的：

是ModelState中實際上是有效的（和你打的代碼來保存數據） ？你的控制器方法的最後一行應該是返回View（model）; （不返回RedirectToAction（「Index」）;），以便驗證錯誤顯示並且可以更正。

public ActionResult Edit_Info(UserVm model) 
{ 
    var id = User.Identity.GetUserId(); 

    if (id != null) 
    { 
     var User_Model = db.AspNetUsers.Find(id); 
     User_Model.NickName = model.User.NickName; 
     User_Model.Email = model.User.Email; 
     User_Model.PhoneNumber = model.User.PhoneNumber; 
     db.Entry(User_Model).State = EntityState.Modified; 
     db.SaveChanges(); 
     return RedirectToAction("Index"); 
    } 
    return view (model); 

}
