I'm trying to make a custom route to my CategoryItems, rather than using default routing (eg. /experiences/calgary-tower/) which can cause potential dublicates, I rather use custom routing (eg. /experiences/canada/alberta/calgary/calgary-tower/1247)

I have two problems:

The ActionResult 'CategoryitemRouted' in my controller, if I return the CurrentTemplate I get this error 'No physical template file was found for template CategoryitemRouted'. If I returns the view directly, I cannot inherit anything from my master template. So any of these solutions is'nt quite helpfull :|
How do I get content passed to my Template through the model. I need at least the Id in order to display my content... :-)

My files:

//My Composer
namespace Umbraco8.Project.Composers
{
    public class RegisterCustomRouteComposer : IUserComposer
    {
        public void Compose(Composition composition)
        {
            composition.Components().Append<RegisterCustomRouteComponent>();
        }
    }
}


//My Component
namespace Umbraco8.Project.Components
{
    public class RegisterCustomRouteComponent : IComponent
    {
        public void Initialize()
        {
            RouteTable.Routes.MapRoute(
                name: "Category Items Routed",
                url: "{category}/{country}/{state}/{city}/{displayName}/{id}",
                defaults: new {
                    controller = "Categoryitem",
                    action = "CategoryitemRouted",
                    state = UrlParameter.Optional
                });
        }

        public void Terminate()
        {
            throw new NotImplementedException();
        }
    }
}

//My Controller
namespace Umbraco8.Project.Controllers
{
    public class CategoryitemController : RenderMvcController
    {
        public override ActionResult Index(ContentModel model)
        {
            return CurrentTemplate(model);
        }

        public ActionResult CategoryitemRouted(ContentModel model, int id)
        {
            return CurrentTemplate(model);
        //return View("~/views/CategoryitemRouted.cshtml", model);
        }
    }
}

Hi all, I managed so solve my own problem using this tutorial: https://our.umbraco.com/documentation/reference/routing/custom-routes and it now works as intended.

My code:

public class RegisterCustomRouteComponent : IComponent
{
    private readonly IUmbracoContextFactory _context;

    public RegisterCustomRouteComponent(IUmbracoContextFactory context)
    {
        _context = context;
    }

    //Real World Example: https://our.umbraco.com/documentation/reference/routing/custom-routes
    public void Initialize()
    {
        using (var cref = _context.EnsureUmbracoContext())
        {
            IPublishedContentCache umbracoHelper = cref.UmbracoContext.Content;
            IEnumerable<IPublishedContent> categoryListing = umbracoHelper.GetByXPath("//categoryitem");


            foreach (var item in categoryListing)
            {
                RouteTable.Routes.MapUmbracoRoute(
                name: "CategoryItem-" + item.Id,
                url: UrlHelpers.GetCategoryItemUrl(item.Id).TrimStart('/'),
                new
                {
                    controller = "Categoryitem",
                    action = "Categoryitem"
                },
                new CategoryitemHandler(item));
            }
        }
    }

    public void Terminate()
    {
        //throw new NotImplementedException();
    }
}

public class CategoryitemHandler : UmbracoVirtualNodeRouteHandler
{
    private readonly IPublishedContent _node;

    public CategoryitemHandler(IPublishedContent node)
    {
        _node = node;
    }

    protected override IPublishedContent FindContent(RequestContext requestContext, UmbracoContext umbracoContext)
    {
        return _node;
    }
}

Though I'm facing a new challenge! - When I update a node, the changes does'nt show up when i view the page with a custom route, it's it is heavily cached. Any idea how to clear/bypass the cache when using custom routing...?
