ASP.NET MVC 4复杂的模型验证 - 模型不验证服务器端 [英] ASP.NET MVC 4 validation on complex models - model does not validated on server side

问题描述

我的问题是类似于<一href=\"http://stackoverflow.com/questions/18087358/asp-net-mvc-4-unobtrusive-validation-broken-on-complex-models\">this问题但我仍然有验证服务器端和客户端的问题。我想进行比较的两个属性，在不同的模型设定。

我的模型如下：

 公共类用户{
  公共字符串密码{搞定;组; }
}公共类UserRegisterViewModel {
    公众用户用户{搞定;组; }    //这个建议在链接的问题 - 因为比较只能与本地产业合作
    公共字符串密码
    {
        {返回this.User.Password;}
    }    [数据类型（DataType.Password）
    [比较（密码的ErrorMessage =密码必须匹配）]
    [必需（的ErrorMessage =确认需要输入密码）]
    [显示名称（确认密码）]
    公共字符串CPassword {搞定;组; }
}
 

我的控制器动作是：

  [HttpPost]
[使用AllowAnonymous]
[ValidateAntiForgeryToken]
公众的ActionResult寄存器（UserRegisterViewModel模型）
{
    如果（ModelState.IsValid）//此条件是假的
    {
    }
    返回查看（）;
}
 

据重定向到再次验证错误说密码必须匹配注册页面。是否有人可以帮忙吗？我已经检查<一个href=\"http://stackoverflow.com/questions/18087358/asp-net-mvc-4-unobtrusive-validation-broken-on-complex-models\">this 的问题，它帮助了一点，但不是全部。

如果我改变模型结构如下图所示，比我得到一个错误说：找不到一个名为user.password的属性：

 公共类UserRegisterViewModel {
    公众用户用户{搞定;组; }    [数据类型（DataType.Password）
    [比较（user.password的的ErrorMessage =密码必须匹配）]
    [必需（的ErrorMessage =确认需要输入密码）]
    [显示名称（确认密码）]
    公共字符串CPassword {搞定;组; }
}
 

修改

我CSHTML页code是像下面。

 ＆LT; P＆GT;
    @ Html.LabelFor（型号=＆GT; model.User.Password）
    @ Html.PasswordFor（型号=＆GT; model.User.Password，新{@class =wd189 inputText的}）
    @ Html.ValidationMessageFor（型号=＆GT; model.User.Password）
＆所述; / P＆GT;
＆所述p为H.;
    @ Html.LabelFor（型号=＆GT; model.CPassword）
    @ Html.PasswordFor（型号=＆GT; model.CPassword，新{@class =wd189 inputText的}）
    @ Html.ValidationMessageFor（型号=＆GT; model.CPassword）
＆所述; / P＆GT;
 

解决方案

这为我工作（适用于：客户端和服务器端）

。

 公共类UserRegisterViewModel
{
    私人用户_user;    公众用户用户
    {
        {返回_user =（_user ??新用户（））; }
    }    公共字符串密码
    {
        {返回user.password的; }
        集合{user.password的=价值; }
    }    [数据类型（DataType.Password）
    [System.Web.Mvc.Compare（密码的ErrorMessage =密码必须匹配）]
    [必需（的ErrorMessage =确认需要输入密码）]
    [显示名称（确认密码）]
    公共字符串CPassword {搞定;组; }
}
 

修改

的显然，认为必须如下所示：的

 ＆LT; P＆GT;
    @ Html.LabelFor（型号=＆GT; model.Password）
    @ Html.PasswordFor（型号=＆GT; model.Password，新{@class =wd189 inputText的}）
    @ Html.ValidationMessageFor（型号=＆GT; model.Password）
＆所述; / P＆GT;
＆所述p为H.;
    @ Html.LabelFor（型号=＆GT; model.CPassword）
    @ Html.PasswordFor（型号=＆GT; model.CPassword，新{@class =wd189 inputText的}）
    @ Html.ValidationMessageFor（型号=＆GT; model.CPassword）
＆所述; / P＆GT;
 

My problem is similar to this question but I'm still having problem with validation both server- and client-side. I want to perform a compare on two properties, set in different models.

My models are as follows:

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; }
}

My Controller action is:

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

It redirects to again register page with the validation error saying Password must match. Can someone please help ? I have checked this question it helped a bit, but not completely.

If I change the model structure like below, than I get an error saying: 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; }
}

EDIT

My cshtml page code is like below.

<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>

解决方案

This worked for me (for both: client and server sides).

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; }
}

EDIT:

and obviously, the view must be as follows:

<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>
