Passing model data onto another view

Question

So I've tried to follow multiple threads on here to do what I am to, and so far it all seems to have something to do with a singleton which I think is a bit over-the-top solution for my issue.

I'm trying to do the following: I have my login async task which is executed when the user logins in a partial view, then it takes a LoginViewModel as a parameter, when succesfully logged in this happens:

case SignInStatus.Success:
return RedirectToLocal(returnUrl);

Afterwards when my users click into the Member section as follows:

@Html.ActionLink("Medlemsområde", "LoggedIn", "Home", null, new { @class = "login-field btn btn-primary" })

My home controller looks like this

public ActionResult LoggedIn()
{
    if (User.Identity.IsAuthenticated)
        return View("Dashboard");
    else
        return View("Login");
}

My dashboard looks like this

@{
    Html.RenderAction("Index", "Manage");
 }

And then I have my Manage controller

public async Task<ActionResult> Index(ManageMessageId? message)
{
            ViewBag.StatusMessage =
                message == ManageMessageId.ChangePasswordSuccess ? "Dit password er blevet ændret."
                : message == ManageMessageId.SetPasswordSuccess ? "Dit password er gemt."
                : message == ManageMessageId.SetTwoFactorSuccess ? "Din to-faktor godkendelse er gemt."
                : message == ManageMessageId.Error ? "Der skete en fejl."
                : message == ManageMessageId.AddPhoneSuccess ? "Dit telefon nummer blev tilføjet."
                : message == ManageMessageId.RemovePhoneSuccess ? "Dit telefon nummer blev fjernet."
                : "";

            var userId = User.Identity.GetUserId();
            var model = new IndexViewModel
            {
                HasPassword = HasPassword(),
                PhoneNumber = await UserManager.GetPhoneNumberAsync(userId),
                TwoFactor = await UserManager.GetTwoFactorEnabledAsync(userId),
                Logins = await UserManager.GetLoginsAsync(userId),
                BrowserRemembered = await AuthenticationManager.TwoFactorBrowserRememberedAsync(userId)
            };
            return View(model);
}

Whenever I have

Html.RenderAction("Index", "Manage");

I get the following error:

The model item passed into the dictionary is of type 'ClientSideProgramming.Models.IndexViewModel', but this dictionary requires a model item of type 'ClientSideProgramming.Models.LoginViewModel'.

How can I fix this without ending up with either passing models all around, or having a singleton?

Answer 1

I think you should probably do

return RedirectToAction("Index");

instead of return View("Dashboard") when you are successfully logged in.
