I am very new to Umbraco and I need help understanding how I can inherit umbraco modelproperties to my custom model loginViewModel.

My loginViewModel is used on a view called Mypages (MinaSidor). And i like to enable some part of the view to be modified by the umbraco backoffice users. They should be able to set new bodyText and etc.

I am trying to map my view to the umbracos PublishedModels.

My @Model has the context of LoginviewModel and the ContenModels has the context of MinaSidor, (Umbraco.Web.PublishedModels.MinaSidor;)

I have tried to implement IpublishedContent on my model but I keep generating NullreferenceException whenever i call any action from my controller.

View;

@inherits Umbraco.Web.Mvc.UmbracoViewPage<legimusWeb.ViewModels.LoginViewModel>
@using ContentModels = Umbraco.Web.PublishedModels.MinaSidor;
@{
Layout = "Master.cshtml";
}
<h1>@Model.UserInformationModel.userRole</h1>
<h1>@ContentModels.GetModelPropertyType(x => x.BodyText)</h1>
@if (User.Identity.IsAuthenticated)
{ [...]

Model without IpublishContent

public class LoginViewModel
{
    private IPublishedContent _publishedContent;
    public LoginViewModel() { }

    [Required]
    [DisplayName("Epost")]
    [DataType(DataType.EmailAddress)]
    public string Username { get; set; }
    [Required]
    [DisplayName("Lösenord")]
    [DataType(DataType.Password)]
    public string Password { get; set; }
    public UserInformationModel UserInformationModel { get; set; }

If the solution is to inherit from Ipublishcontent in my loginViewModel Could anyone give an example to avoid the nullreference exception on the controller.

Controller:

[HttpPost] [ValidateAntiForgeryToken] public async Task

        try
        {
            var response = await _authenticationService.LoginUserAndGetTicketAsync(new AuthorizeCurrentUserInputModel()
            {
                ndsUserName = loginViewModel.Username,
                ndsUserPasswd = loginViewModel.Password
            });
            success = response.Item1;
            ticket = response.Item2;

        } catch (Exception e)
        {
            this.ModelState.AddModelError(String.Empty, @"Något gick fel.");
            return View("Login", loginViewModel);
        }

        if (success)
        {
            FormsAuthentication.SetAuthCookie(loginViewModel.Username, true);
            Session["ticketkey"] = ticket;
            if (!Request.RawUrl.Contains("/mina-sidor/"))
            {
                return Redirect("/");
            }
            //Mina sidor redirect
            return Redirect("/mina-sidor/");
        }
        else
        {
            this.ModelState.AddModelError(String.Empty, @"Användarnamn eller lösenord är fel.");
        }

        return View("Login", loginViewModel);
    }
