MVC3: Derleyici Hata İletisi: CS0103: Geçerli modelde 'model' adı mevcut değil

Question

Modelimi jilet görünümünde kullanmaya çalışıyorum ve yukarıda belirtilen hatayı alıyorum. @model anahtar sözcüğünü içeren MVC3'te üretilen varsayılan kod (Account \ ChangePassword.cshtml, ... etc) iyi çalışıyor, sadece yeni görünümüm sorun yaşıyor.

şöyle cshtml dosyasında Benim kodudur:

aşağıdaki

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using System.Web.Security; 
using System.ComponentModel.DataAnnotations; 

namespace VidLib.Models 
{ 
    public class LogedInUsersModel 
    { 
     public MembershipUserCollection GetUsers() 
     { 
      return Membership.GetAllUsers(); 
     } 

    } 

} 

alıyorum hata olarak: şu şekildedir:

@model VidLib.Models.LogedInUsersModel 


@{ 
    ViewBag.Title = "LogedInUsers"; 
} 

<h2>LoggedInUsers</h2> 

@foreach (MembershipUser user in model.GetUsers()) 
{ 
    <p>Name: @user.UserName 
    </p> 
} 

Benim modelim kodudur

Answer 1

Görünümünüzdeki (LogedInUsers.cshtml) dosyayı kontrol edin. It adlı Modeli,

@foreach modelleyemez (Model.GetUsers içinde MembershipUser kullanıcı()) {

Answer 2

benim uygulamada iki sorun vardı.

1) Model, Mik-Mark'ın önerdiği gibi model yerine Görünümde kullanılmalıdır. 2) Modelimi, yapmadığım denetleyicide View'a geçirmem gerekiyor.

[Authorize(Roles = "Admin")] 
public ActionResult LogedInUsers() 
{ 
     var model = new LogedInUsersModel(); 
     return View(model); 
} 

Answer 3

Modelinizden birden çok kayıt döndüğünüzü varsayıyorum. Bir modele model bağlamayı denemedim, işe yaradığından emin değilim. Bir mülkü deneyebilirim. Model

public class User 
{ 
    public int UserId { get; set; } 
    public string UserName { get; set; } 
} 

ViewModel

public class UserViewModel { get; set; } 
{ 
    public List<User> UserList { get; set; } 
} 

kontrol

DBContext db = new DBContext(); 

public ViewResult() 
{ 
    List<Users> users = db.Users.Where(m => m.LoggedIn == true).ToList(); 

    UserViewModel userVM = new UserViewModel(); 

    userVM.UserList = users; 

    return View(userVM); 
} 

@model MyUserApp.ViewModels.UserViewModel 

foreach(User u in Model.Users) 
{ 
    Name: @u.UserName<br/> 
} 

özellikleri yerine yöntemler bağlanma deneyin görünüşüdür. Veritabanına bağlı Modelinizden ziyade bir ViewModel'e bağlamayı da düşünmelisiniz. Görünümü doğrudan veri deposu modeline veya havuzuna bağladığınızda, modeli görüntüye sıkı sıkıya bağlıyorsunuz demektir. Model daha sonra hem görünüme hem de veritabanına bağlıdır (varlık çerçevesini ve veri ek açıklamalarını kullandığınızı varsayarak). Bu, bir modeli görünüm ve veritabanına karşı doğrulamaya çalıştığınızda çok sayıda veri doğrulama hatasına neden olabilir. Örneğin bu nitelikler Kural olarak modelin

[Required(ErrorMessage="User name is required")] 
[StringLenth(50)] // this causes validation against the database and the view 
public string UserName { get; set; } 

eklenirse, kullanım verisi açıklama Modelinizdeki veritabanı tanımlamak ve sonra ViewModel UI doğrulama yapmak yardım etmek bağlıyor. Aynı nitelikleri görünüm modeline eklerseniz, yalnızca görünüme karşı doğrulama yaparsınız.
