複雜模型上的ASP.NET MVC 4驗證 - 模型未在服務器端進行驗證

Question

我的問題與this question類似，但我仍然在驗證服務器端和客戶端方面存在問題。我想對兩個屬性進行比較，並設置在不同的模型中。

我的型號如下：

public class User{ 
    public string Password { get; set; } 
} 

public class UserRegisterViewModel { 
    public User User{ get; set; } 

    //This is suggested in linked question - as Compare can only work with local property 
    public string Password 
    { 
     get{return this.User.Password;} 
    } 

    [DataType(DataType.Password)] 
    [Compare("Password", ErrorMessage = "Passwords must match")] 
    [Required(ErrorMessage = "Confirm password is required")] 
    [DisplayName("Confirm Password")] 
    public string CPassword { get; set; } 
} 

我的控制器操作是：

[HttpPost] 
[AllowAnonymous] 
[ValidateAntiForgeryToken] 
public ActionResult Register(UserRegisterViewModel model) 
{ 
    if (ModelState.IsValid) //This conditions is false 
    { 
    } 
    return View(); 
} 

它重定向到再次驗證錯誤說Password must match註冊頁面。有人可以幫忙嗎？我檢查了this question它有點幫助，但不完全。

如果我改變模型結構如下圖所示，比我得到一個錯誤說：Could not find a property named User.Password：

public class UserRegisterViewModel { 
    public User User{ get; set; } 

    [DataType(DataType.Password)] 
    [Compare("User.Password", ErrorMessage = "Passwords must match")] 
    [Required(ErrorMessage = "Confirm password is required")] 
    [DisplayName("Confirm Password")] 
    public string CPassword { get; set; } 
}

我CSHTML頁面的代碼如下圖所示。

<p> 
    @Html.LabelFor(model => model.User.Password) 
    @Html.PasswordFor(model => model.User.Password, new { @class = "wd189 inputtext" }) 
    @Html.ValidationMessageFor(model => model.User.Password) 
</p> 
<p> 
    @Html.LabelFor(model => model.CPassword) 
    @Html.PasswordFor(model => model.CPassword, new { @class = "wd189 inputtext" }) 
    @Html.ValidationMessageFor(model => model.CPassword) 
</p> 

Answer 1

在您的註冊視圖中，您需要引用用戶模型的密碼，而不是UserRegisterViewModel模型的密碼。如下圖所示：

@model UserRegisterViewModel 

@Html.LabelFor(model => model.User.Password) 
@Html.EditorFor(model => model.User.Password) 
@Html.ValidationMessageFor(model => model.User.Password) 

@Html.LabelFor(model => model.CPassword) 
@Html.EditorFor(model => model.CPassword) 
@Html.ValidationMessageFor(model => model.CPassword) 

public class User 
{ 
    [DataType(DataType.Password)] 
    public string Password { get; set; } 
} 

public class UserRegisterViewModel 
{ 
    public User User { get; set; } 
    public string Password{get { return this.User.Password; }} 

    [DataType(DataType.Password)] 
    [Compare("Password", ErrorMessage = "Passwords must match")] 
    [Required(ErrorMessage = "Confirm password is required")] 
    [DisplayName("Confirm Password")] 
    public string CPassword { get; set; } 
} 

Answer 2

請你檢查這article？我認爲它會幫助你。

例子：

public class RegisterModelValidator : AbstractValidator<RegisterModel> 
{ 
    public RegisterModelValidator() 
    { 
     RuleFor(x => x.UserName) 
      .NotNull(); 
     RuleFor(x => x.ConfirmPassword) 
      .Equal(x => x.User.Password); 
    } 
} 

而另一one arcticle也可以解決問題。

Answer 3

這適用於我（對於客戶端和服務器端）。

public class UserRegisterViewModel 
{ 
    private User _user; 

    public User User 
    { 
     get { return _user = (_user ?? new User()); } 
    } 

    public string Password 
    { 
     get { return User.Password; } 
     set { User.Password = value; } 
    } 

    [DataType(DataType.Password)] 
    [System.Web.Mvc.Compare("Password", ErrorMessage = "Passwords must match")] 
    [Required(ErrorMessage = "Confirm password is required")] 
    [DisplayName("Confirm Password")] 
    public string CPassword { get; set; } 
}

，顯然，認爲必須如下：

<p> 
    @Html.LabelFor(model => model.Password) 
    @Html.PasswordFor(model => model.Password, new { @class = "wd189 inputtext" }) 
    @Html.ValidationMessageFor(model => model.Password) 
</p> 
<p> 
    @Html.LabelFor(model => model.CPassword) 
    @Html.PasswordFor(model => model.CPassword, new { @class = "wd189 inputtext" }) 
    @Html.ValidationMessageFor(model => model.CPassword) 
</p>
