path_prefix for asp.net mvc routes

Question

I read this article about how you can prefix routes in ruby on rails. I want to be able to do the same thing with asp.net mvc

So I want to be able to define a route like :

/photographers/1/photos/2   //photo 2 of photographer with id 1
/photographers/1/photos     //all of photographer with id 1

Any tips ?

EDIT:

"photographers/{id}/photos/{photoID}" - seems to do the job quite ok, BUT how can I support

RedirectToAction<PhotosController>(x => x.Add());

I would like to redirect to : /photographers/1/photos/add

Answer 1

Define your route like this:

routes.MapRoute(
    "Photographers",
    "photographers/{id}/photos/{photoID}",
    new { controller = "Photographers", action = "Photo", photoID = null });

Then define your controller action like this:

public ActionResult Photo(int id, int? photoID)
{
    // If photoID is not null, show just that photo.
    // Otherwise, show all photographs.
}

Answer 2

You could use regex routing or use wildcards in your routing table so that the {id*} matches the /1/photos/2 for the photographers default controller, parse the string, and redirect to an appropriate action.

Also take a look at this post about nested resources.

RouteTable.Routes.Add(
        new Route { Url = "events/[eventId]/tickets/[action]/[id]", 
                    Defaults = new { controller = "Tickets", 
                                     action = "List", id = (string)null }, 
                    RouteHandler = typeof(MvcRouteHandler) });
