MVC遠程驗證從類以上

Question

訪問字段在下面的代碼我的用戶名不傳遞到遠程驗證函數：

public string UserName { get; set; } 

public class Numbers 
{ 


      [Display(Name = "Additonal Numbers")] 
      [Remote("NumberExists", "Account", AdditionalFields = "UserName", ErrorMessage = "Serial is already taken.")] 
      public string additionalNumbers { get; set; } 
} 


public List<Numbers> NumberList { get; set; } 

這是一個簡單的例子，但我想從同一個模型通過附加字段在一個列表中，但我似乎無法訪問公共課範圍外的任何內容。

我是否需要將模型的其餘部分以某種方式傳遞到列表中以實現此目的，還是我在這裏做錯了什麼？

Answer 1

遠程驗證屬性中的AdditionalFields參數需要與正在驗證的對象處於相同的類中。

..edit ..意見後

public class Numbers 
{ 

      public string UserName { get; set; } 

      [Display(Name = "Additonal Numbers")] 
      [Remote("NumberExists", "Account", AdditionalFields = "UserName", ErrorMessage = "Serial is already taken.")] 
      public string additionalNumbers { get; set; } 
} 

..edit .. 看起來你想要做的是驗證所有的號碼都輸入用戶名獨特的東西。試試這個：

public string UserName { get; set; } 

[Display(Name = "Additonal Numbers")] 
[Remote("NumberExists", "Account", AdditionalFields = "UserName", ErrorMessage = "Serial is already taken.")] 
public List<String> NumberList { get; set; } 

在你NumberExists行動採取字符串列表，而不是隻1串。這將讓你一次驗證你的整個數組。

Public ActionResult NumberExists(List<String> NumberList, String UserName){ 
    //Validate list is unique for username 
} 

Answer 2

UserName屬性應該是在同一個類中的additionalNumbers屬性：

public class NumbersViewModel 
{ 
    public string UserName { get; set; } 

    [Display(Name = "Additonal Numbers")] 
    [Remote("NumberExists", "Account", AdditionalFields = "UserName", ErrorMessage = "Serial is already taken.")] 
    public string additionalNumbers { get; set; } 

    public List<Numbers> NumberList { get; set; } 
}
