i ZarejestrujModelUżytkownika
public class RegisterUserModel

private const int EMAIL_LENGTH = 100;
private const int PASSWORD_MIN_LENGTH = 5;
private const int PASSWORD_MAX_LENGTH = 20;

public string PasswordSalt { get; set; }
[Required]
[DefaultValue(UserType.User)]
public UserType Type { get; set; }
public ICollection<Task> Tasks { get; set; }
}
i używam RegisterUserModel jako modelu widoku do rejestracji użytkownika
@model TaskManager.Models.RegisterUserModel
@{
ViewBag.Title = "Registration";
}
<div class="col-md-6">
<h2>Registration</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<div class="form-group">
@Html.LabelFor(u => u.Name)
@Html.TextBoxFor(u => u.Name, new { @class = "form-control" })
@Html.ValidationMessageFor(u => u.Name, null, new { @class = "error" })
</div>
<div class="form-group">
@Html.LabelFor(u => u.Email)
@Html.TextBoxFor(u => u.Email, new { @class = "form-control" })
@Html.ValidationMessageFor(u => u.Email, null, new { @class = "error" })
</div>
<div class="form-group">
@Html.LabelFor(u => u.Password)
@Html.PasswordFor(u => u.Password, new { @class = "form-control" })
@Html.ValidationMessageFor(u => u.Password, null, new { @class = "error" })
</div>
<div>
<input type="submit" class="btn btn-default" value="Registration" />
</div>
}
</div>
UserController
[HttpGet]
public ActionResult Registration()
{
var registerUser = new RegisterUserModel();
return View(registerUser);
}
[HttpPost]
public ActionResult Registration(RegisterUserModel registerUser)
{
var user = new UserModel
{
Name = registerUser.Name,
Email = registerUser.Email,
Password = registerUser.Password
};
if (ModelState.IsValid)
{
if (!IsUserExist(registerUser.Email))
{
var crypto = new SimpleCrypto.PBKDF2();
var encrpPass = crypto.Compute(user.Password);
var newUser = _db.Users.Create();
newUser.Name = user.Name;
newUser.Email = user.Email;
newUser.Type = UserType.User.ToString();
newUser.Password = encrpPass;
newUser.PasswordSalt = crypto.Salt;
_db.Users.Add(newUser);
_db.SaveChanges();
return RedirectToAction("Index", "Task");
}
else
{
ModelState.AddModelError("", User already exists");
}
}
else
{
ModelState.AddModelError("", "Incorrect data");
}
return View(user);
}
ale gdy próbuję na przykład zarejestrować użytkownika z adresem e-mail, który już istnieje w DB, mam Exception.
Element modelu przekazany do słownika jest typu „TaskManager.Models.UserModel”, ale ten słownik wymaga modelu element typu "TaskManager.Models.RegisterUserModel".
System.InvalidOperationException: element modelu przekazany do słownika jest typu „TaskManager.Models.UserModel”, ale to słownik wymaga elementu wzorcowego typu "Menedżer zadań.Modele.ZarejestrujModelUżytkownika".
Co zrobiłem źle? Jak to naprawić?

2 dla odpowiedzi № 1Twój problem jest na samym dole, przekazujesz użytkownika do funkcji View zamiast registerUser.
