How to separate a fixed route from a variable route with Asp.net mvc5

Question

I have a control that manages videos. I’m trying to make these two methods:

[Route("video/categoria/{categoria}")]
public async Task<ActionResult> Index(string categoria)
{


}

[Route("video/categoria/new-movies")]
public async Task<ActionResult> Index()
{


}

When you run the url /video/categoria/new-movies it falls on the route [Route("video/categoria/{categoria}")] putting the value new-movies within the category variable.

I wonder if there’s any way he could land on the other route.

If it does not exist, it is best to treat everything in the same method?

I seek a more technically correct solution to avoid future problems and facilitate maintenance.

Answer 1

Try reversing the methods:

[Route("video/categoria/new-movies")]
public async Task<ActionResult> Index()
{


}

[Route("video/categoria/{categoria}")]
public async Task<ActionResult> Index(string categoria)
{


}

Alternatively, step one more method, which is setting up routes in the RouteConfig. Precedence always begins with the most specific route. The most generic route must be last because it is solved last.

namespace SeuProjeto
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "NovosFilmes",
                url: "video/categoria/new-movies",
                defaults: new { controller = "Videos", action = "Index" }
            );

            routes.MapRoute(
                name: "Filmes",
                url: "video/categoria/{categoria}",
                defaults: new { controller = "Videos", action = "Index", categoria = UrlParameter.Optional }
            );

            ...
        }
    }
}
