远程验证在别处工作

Question

我有一个用户注册页面，我在其中实现了用户名的远程验证概念。我基本上想为每个用户名保留一个唯一值。我能够实现它，但是现在在登录页面中，当我输入用户名时，它会提示一条消息，说用户名不可用。这仅适用于注册页面，而不是登录页面。有人可以解释我在做什么错误。我有一个具有 Username 属性的模型用户；我正在使用远程验证。我有一个名为 UserNameExsists 的 Action 方法，它被触发以进行远程验证。以及用于验证的注册视图。但是登录页面也会触发验证。有没有办法只为注册视图设置它？

型号：

public class User
{
    public int ID { get; set; }
    [Required]
    [Remote("UserNameExists","User",ErrorMessage="Username not available")]
    [Display(Name="User Name")]
    public string UserName { get; set; }
    [Required]
    [DataType(DataType.Password)]
    public string Password { get; set; }
    [Required]
    [Display(Name="First Name")]
    public string FirstName { get; set; }
    [Required]
    [Display(Name="Last Name")]
    public string LastName { get; set; }
    [Required]
    [DataType(DataType.PhoneNumber)]
    [MinLength(10)]
    [MaxLength(10)]
    [Display(Name="Mobile No")]
    public string PhoneNum { get; set; }
}

控制器：（名称是用户）

    //Remote Validation
    public JsonResult UserNameExists(string username)
    {
        bool user = db.Users.Any(p => p.UserName == username) ? false : true;
        return Json(user,JsonRequestBehavior.AllowGet);

    }

您对登录和注册页面使用相同的模型，因此您在两个页面上获得相同的验证。

为每个视图创建一个 ViewModel 并将您的验证属性放在那里。 这样您就可以区分每个页面的验证。
