Question

Umbraco Для этого объекта не определен беспараметрический конструктор

Я пытаюсь сделать частичное представление в Умбрако. у меня есть BaseLayout.cshtml,Homepage.cshtml,BaseLayoutViewModel,HomepageViewModel

Это мой BaseLayout View

@inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.BaseLayoutViewModel>
@{
    Layout = null;
}

<!DOCTYPE html>
<html lang="en-gb">
<head>
</head>
<body>
    @Html.Action("GetPrimaryNavbar", "PrimaryNavbar", Model) //This is there the site throws an error.
    @RenderBody()
</body>
</html>

Это моя модель BaseLayout. Модель домашней страницы наследуется от базовой компоновки.

public class BaseLayoutViewModel : PublishedContentModel
    {
        public BaseLayoutViewModel(IPublishedContent content) : base(content)
        {
        }

        public string PageTitle => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageTitle);
        public string PageDescription => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageDescription);
        public string NavigationName => this.GetPropertyValue<string>(FieldNames.BaseLayout.NavigationName);
    }

Мое частичное представление PrimaryNavbar:

@inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.PrimaryNavbarViewModel>
<header>
<ul>
<li>
</li
</ul>
</header>

И контроллер для PrimaryNavbar это:

 public class PrimaryNavbarController : SurfaceController
    {
        [ChildActionOnly]
        public ActionResult GetPrimaryNavbar(RenderModel model)
        {
            //var primaryNavbarViewModel = new PrimaryNavbarViewModel(model.Content);

            return PartialView("PrimaryNavbar");//, primaryNavbarViewModel);
        }
    }

Я не могу понять, почему я получаю "Не определен конструктор без параметров для этого объекта". Может ли кто-нибудь помочь мне в этом?

Спасибо

Чтобы решить проблему, вам нужно отправить модель следующим образом:

@Html.Action("GetPrimaryNavbar", "PrimaryNavbar", new { model = Model })
