Question

我正在使用MVC5。我有一个模型调用User，它有几个属性。其中一些是必需的，例如Password和ConfirmPassword。

看起来像这样。

public partial class Users
{
    public long User_id { get; set; }
     [Required]
     public string Password { get; set; }
    [NotMapped] // Does not effect with database
     [Compare("Password")]
    public virtual string ConfirmPassword { get; set; }
}

视图继承自模型，看起来像这样。

public class UserViewModel
{
    public Users user { get; set; }
    public IList<SelectListItem> AvailableCountries { get; set; }
}

当我更新用户时。我不会渲染密码和ConfirmPassoword。

我的更新Mehtod是这样的。

public async Task<ActionResult> Update(UserViewModel model)
{
     ModelState.Remove("Password");
     ModelState.Remove("ConfirmPassword");
     if (ModelState.IsValid)
     {
     }
}

我想禁用验证，因此，正如在几个站点中所说的那样，我在控制器中添加以下内容

ModelState.Remove

但是当我要求ModelState.IsValid时，它总是假的......

这是因为数据验证位于Users类，我是从UserViewModel继承的吗？

为什么它不起作用？

我的观点在这里

@model TableAvivaVoz.Models.UserViewModel
@{
    ViewBag.Title = "Edit";

}

<h2>Editar</h2>
@using (Html.BeginForm("Update", "Users", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()

Answer 1

不要在您的实体中添加数据注释。您必须在ViewModel中添加数据注释，以便View是强类型的用户ViewModel。

模式州考虑UserViwMode

因此，您必须在UserViewModel中删除public Users user { get; set; }并添加此更改：

public class UserViewModel
{
  puclic string Name { get; set; }

  puclic string LastName { get; set; }

  puclic bool sex { get; set; }

  // and more ...

  public IList<SelectListItem> AvailableCountries { get; set; }
}

Answer 2

我解决了这个问题，就像斯蒂芬说的那样。我复制用户实体和UserModel并使用Mapper映射这些模型。就这样 example

MVC数据验证仅插入表单
