Question

I’m developing an MVC 3 app

I want to have a url something like:

/some-product-name-goes-here-4726482648
(with 4726482648 being the product id)

I do have other pages such as:

/category-name
(allows browsing by category)

/about

etc…

How could I go about setting up routing to allow this?

Answer 1

You would certainly be using a RouteConstraint here

in your routes you could have something like this:

routes.MapRoute("CustomProductUrl",
                 "{Product}",
                 new { controller = "Product", action = "Index" },
                 new { Product= new ProductConstraint() }
                );

then in your ProductConstraint class you would have something as follows:

    public class ProductConstraint : IRouteConstraint
    {

        public ProductConstraint ()
        {
        }

        public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
        {
            //do your logic in here to split the name and the id and amke sure it is valid data

            //if valid return true;
            //else false;
        }

    } 

lastly in the Method signature of the Index action (or action in the route) take the string of the – and then split it down and process as appropriate

let me know if there are any issues
