In asp.net mvc, if you have two routes with the same number of parameters and no constraints, first route will be called.

Can you check this thread: http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=121971

Hi Dejan, i checked your thread, and i found your last post there interesting.. about adding constraints. 

But i don't quite follow how to apply constraints in my case. How can i differentiate between my routes. As you can see in my PageContollerBase. i have my actions defined which are hit using matching url pattern.

I'm running latest EPiServer 8.8.x version at the moment.

Hope you can give some more insight in my case.

Hi,

Something like this?

public class CustomConstraint : IContentRouteConstraint
{
    private readonly Type _contentType;
    private readonly string _actionName;


    private readonly IContentLoader _contentLoader = ServiceLocator.Current.GetInstance<IContentLoader>();

    public CustomConstraint(Type contentType, string actionName)
    {
        _contentType = contentType;
        _actionName = actionName;
    }

    public bool Match(Route route, SegmentContext segmentContext, string parameterName)
    {
        if (ContentReference.IsNullOrEmpty(segmentContext.RoutedContentLink))
        {
            return false;
        }

        var content = _contentLoader.Get<IContent>(segmentContext.RoutedContentLink);

        // constraint 1: content types must match
        if (_contentType.IsInstanceOfType(content))
        {
            // constraint 2: actions must match
            if (segmentContext.RouteData.Values.ContainsKey("action") &&
                string.Equals(segmentContext.RouteData.Values["action"] as string, _actionName,
                                StringComparison.CurrentCultureIgnoreCase))
            {
                return true;
            }
        }

        return false;
    }
}

[InitializableModule]
[ModuleDependency(typeof(ServiceContainerInitialization))]
public class CustomRoutingModule : IInitializableModule
{
    public void RegisterRoutes(RouteCollection routes)
    {
        RouteTable.Routes.MapContentRoute(null, "{language}/{node}/{action}/{name}/{pid}",
                                            new
                                            {
                                                action = "Index",
                                                name = UrlParameter.Optional,
                                                pid = UrlParameter.Optional
                                            },
                                            new MapContentRouteParameters
                                            {
                                                Constraints = new
                                                {
                                                    x = new CustomConstraint(typeof(SitePageData), "showcase")
                                                }
                                            });

        RouteTable.Routes.MapContentRoute(null, "{language}/{node}/{action}/{name}/{sid}",
                                            new
                                            {
                                                action = "Index",
                                                name = UrlParameter.Optional,
                                                sid = UrlParameter.Optional
                                            },
                                            new MapContentRouteParameters
                                            {
                                                Constraints = new
                                                {
                                                    x = new CustomConstraint(typeof(SitePageData), "epib")
                                                }
                                            });
    }

    public void Initialize(InitializationEngine context)
    {
        RegisterRoutes(RouteTable.Routes);
    }

    public void Uninitialize(InitializationEngine context)
    {
    }

    public void Preload(string[] parameters)
    {
    }
}

I'm sure there's a much more easier / epi-friendly way to solve this, but this should do the trick in the meantime :)

awesome dejan...

i will dive into what exactly we are doing here, but i implemented this and it works... why do we have the action="Index" now for the routes? I thought the action name must match the action in my controller... How does that work?

C/p, sorry :)

You can remove action="Index", you don't need it (at least in version 8.8.1). It seems that action="something" doesn't have any effect here.

i thought so... thanks for getting back... :-)
