FluentValidation ModelState.IsValid始终为true [英] FluentValidation ModelState.IsValid always true

问题描述

好吧，我的问题是来自fluentValidation的modelvalidator在我的项目中不起作用，并且无论验证状态如何，ModelState.IsValid始终为true，我预先使用了asp.net mvc 4，.net 4.5，thx. /p>

Global.asax

protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
        FluentValidationModelValidatorProvider.Configure();
    }

LoginViewModel

using FluentValidation.Attributes;

namespace ViewModel.Cuentas
{

 [Validator(typeof(LoginViewModel))]
 public class LoginViewModel
 {
    public string UserName { get; set; }
    public string Password { get; set; }
 }
}

LoginViewModelValidator

using FluentValidation;
using FluentValidation.Results;
namespace ViewModel.Cuentas.Validadores
{
    public class LoginViewModelValidator : AbstractValidator<LoginViewModel>
    {
        public LoginViewModelValidator()
        {
        RuleFor(x => x.UserName).NotEmpty().WithMessage("El Campo Usuario es Necesario");
        RuleFor(x => x.Password).NotEmpty().WithMessage("El Campo Usuario es Necesario");
        }
   }
}

和我的客户经理

   [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginViewModel viewModel)
    {
        if (!ModelState.IsValid)
        {
            return View();
        }
        FormsAuthentication.SetAuthCookie(viewModel.UserName, false);
        if (!String.IsNullOrEmpty(returnUrl) && returnUrl != "/")
        {
            return Redirect(returnUrl);
        }
        return RedirectToAction("Enviar", "Cartas");
    }

解决方案

您的Validator属性似乎具有错误的类型.你有:

[Validator(typeof(LoginViewModel))]
public class LoginViewModel

type参数应该是您的验证器类-LoginViewModelValidator.就像这样:

[Validator(typeof(LoginViewModelValidator))]
public class LoginViewModel

Ok my problem is the modelvalidator from fluentValidation is not working in my project, and ModelState.IsValid is always true no matter the state of the validation, im using asp.net mvc 4, .net 4.5, thx in advance.

Global.asax

protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        AuthConfig.RegisterAuth();
        FluentValidationModelValidatorProvider.Configure();
    }

LoginViewModel

using FluentValidation.Attributes;

namespace ViewModel.Cuentas
{

 [Validator(typeof(LoginViewModel))]
 public class LoginViewModel
 {
    public string UserName { get; set; }
    public string Password { get; set; }
 }
}

LoginViewModelValidator

using FluentValidation;
using FluentValidation.Results;
namespace ViewModel.Cuentas.Validadores
{
    public class LoginViewModelValidator : AbstractValidator<LoginViewModel>
    {
        public LoginViewModelValidator()
        {
        RuleFor(x => x.UserName).NotEmpty().WithMessage("El Campo Usuario es Necesario");
        RuleFor(x => x.Password).NotEmpty().WithMessage("El Campo Usuario es Necesario");
        }
   }
}

and my account controller

   [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginViewModel viewModel)
    {
        if (!ModelState.IsValid)
        {
            return View();
        }
        FormsAuthentication.SetAuthCookie(viewModel.UserName, false);
        if (!String.IsNullOrEmpty(returnUrl) && returnUrl != "/")
        {
            return Redirect(returnUrl);
        }
        return RedirectToAction("Enviar", "Cartas");
    }

解决方案

Your Validator attribute appears to have the wrong type. You have:

[Validator(typeof(LoginViewModel))]
public class LoginViewModel

The type argument should be your validator class - LoginViewModelValidator. So it would be like this:

[Validator(typeof(LoginViewModelValidator))]
public class LoginViewModel
