MVC 3 routing help with dynamic route - asp.net-mvc

Question

Im trying to do something like this:
routes.MapRoute("Product", "{product}/{id}",
new
{
action = "Product",
controller = "Home",
product = UrlParameter.Optional,
id = UrlParameter.Optional
});
It gives me error when im trying to load page 404 i think,
Im trying to make the url look like this: www.tables.com/productName/ID .
How can i do it without adding a strong type word like this:
routes.MapRoute("Product", "Products/{product}/{id}", ... )
rest of the routes:
routes.MapRoute("Product", "{product}/{id}",
new
{
action = "Product",
controller = "Home",
product = UrlParameter.Optional,
id = UrlParameter.Optional
});
routes.MapRoute("Category", "Category/{category}/{template}",
new
{
action = "Index",
controller = "Category",
category = UrlParameter.Optional,
template = UrlParameter.Optional
});
routes.MapRoute("Profile", "Profile/{fullName}",
new
{
action = "Index",
controller = "Profile",
fullName = UrlParameter.Optional
});
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
thanks.

Your problem is that the Product route will match everything not starting with Category or Profile.
I would place the product route just before the default route and use a IRouteConstraint such that it doesn't match non products.
Code sample:
routes.MapRoute("Category", "Category/{category}/{template}",
new
{
action = "Index",
controller = "Category",
category = UrlParameter.Optional,
template = UrlParameter.Optional
});
routes.MapRoute("Profile", "Profile/{fullName}",
new
{
action = "Index",
controller = "Profile",
fullName = UrlParameter.Optional
});
routes.MapRoute("Product", "{product}/{id}",
new
{
action = "Product",
controller = "Home",
product = UrlParameter.Optional,
id = UrlParameter.Optional
},
new { product = new ProductRouteConstraint() });
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
And the route constraint:
public class ProductRouteConstraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
if (routeDirection == RouteDirection.IncomingRequest &&
parameterName.ToLowerInvariant() == "product")
{
var productName = values[parameterName] as string;
if (productName == null)
return false;
var productId = values["id"] as string;
if (productId == null)
returns false;
return ProductCatalogue.HasProductById(productId);
}
return false;
}
}
The ProductCatalogue should obviously be replaced with however you lookup products in your system.
