Csdrhrt

pls i'm getting error whenever i try to update my user identity model through a childonly partial view.
This is my partial method:

 [HttpGet]

   [ChildActionOnly]

    public ActionResult CheckOut(string Id)

    {

        Id = HttpContext.User.Identity.GetUserId();

        var pickupuser = db.Users.Single(s => s.Id == Id);

        CheckOutViewModel p = new CheckOutViewModel();

        pickupuser.SurName = p.SurName;

        pickupuser.UserName = p.UserName;

        pickupuser.FirstName = p.FirstName;

        pickupuser.DeliveryAddress = p.DeliveryAddress;

        pickupuser.CustomerPhone = p.CustomerPhone;

        pickupuser.DeliveryDate = p.DeliveryDate;

        pickupuser.DeliveryTime = p.DeliveryTime;

        pickupuser.CouponCode = p.CouponCode;

        return PartialView("CheckOut", pickupuser);

    }



    [HttpPost]

    [ValidateAntiForgeryToken]

    public async Task<ActionResult> CheckOut(CheckOutViewModel appuser)

    {

        if (ModelState.IsValid)

        {

            var currentUser = User.Identity.GetUserId();

            var cUser = db.Users.Single(u => u.Id == currentUser);

            cUser.FirstName = appuser.FirstName;

            cUser.SurName = appuser.SurName;

            cUser.UserName = appuser.UserName;

            cUser.CustomerPhone = appuser.CustomerPhone;

            cUser.DeliveryDate = appuser.DeliveryDate;

            cUser.DeliveryTime = appuser.DeliveryTime;

            cUser.CouponCode = appuser.CouponCode;



            try

            {

                //db.Entry(applicationUser).State = EntityState.Modified;

                await db.SaveChangesAsync();

            }

            catch (DbEntityValidationException ex)

            {

                var errorMessages = ex.EntityValidationErrors

                    .SelectMany(x => x.ValidationErrors)

                    .Select(x => x.ErrorMessage);

                var fullMessage = string.Join("", errorMessages);

                var exceptionMessage = string.Concat(ex.Message, "The validation errors are:", fullMessage);

                throw new DbEntityValidationException(exceptionMessage, ex.EntityValidationErrors);

            }

        }

        return View(appuser);

    }

and the error i'm getting:

Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.The validation errors are:The UserName field is required.

This is the parent method that i passed the CheckOut() method into:

 public ActionResult DisplayCheckOut()

    {

        List<ProductsViewModel> ShoppingCart = productList;

        var cUsers = HttpContext.User.Identity.Name;

        ViewBag.email = db.Users.Where(d => d.UserName == cUsers).Select(a => a.Email).SingleOrDefault();

        ViewBag.phone = db.Users.Where(d => d.UserName == cUsers).Select(a => a.CustomerPhone).SingleOrDefault();

        return View(ShoppingCart);

    }

my identity model class:

public class ApplicationUser : IdentityUser

{

    public string CustomerPhone { get; set; }

    public string CustomerLocation { get; set; }

    public string CustomerImage { get; set; }

    public string SurName { get; set; }

    public string FirstName { get; set; }

    public string CouponCode { get; set; }

    [DataType(DataType.Date)]

    public DateTime? DeliveryDate { get; set; }

    [DataType(DataType.Time)]

    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "0:HH:mm")]

    public DateTime? DeliveryTime { get; set; }

    public string OrderStatus { get; set; }

    public string DeliveryAddress { get; set; }

    public string TableNo { get; set; }

    public string Comment { get; set; }





    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)

    {

        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType

        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

        // Add custom user claims here

        return userIdentity;

    }

}

my view model:

 public class CheckOutViewModel

{

    [Display(Name = "Surname")]

    public string SurName { get; set; }



    [Display(Name = "Firstname")]

    public string FirstName { get; set; }



    [Display(Name = "Phone No")]

    public string CustomerPhone { get; set; }

    public string UserName { get; set; }



    [Display(Name = "Shipping Address")]

    //public string CustomerLocation { get; set; }

    public DateTime? DeliveryTime { get; set; }

    public DateTime? DeliveryDate { get; set; }

    public string DeliveryAddress { get; set; }



    [Display(Name = "Enter Coupon Code")]

    public string CouponCode { get; set; }

}

Conclusion: i have checked all my properties and my viewmodels username is a string and is not required. could it be from the database. thanks
