Hi Team

What could be the reason why my routing is not working? I have configured this to my Routing.cs page. Please i need some assistance to this problem.

What I have tried:

// Route to CoursesRegistered
         routes.MapRoute(
             name:"CoursesRegistration",
             url:"courses-enrolled-for/",
             defaults: new {controller="Home", action = "CoursesRegistration", url = UrlParameter.Optional}

          );

[HttpPost]
 public ActionResult CoursesRegistration( eNtsaRegCourses model)
   {
       if(ModelState.IsValid)
       {
           try
           {
               cb.SaveChanges();
               return Json(new { success = true });
           }catch(Exception ex)
           {
               ModelState.AddModelError("", ex.Message);
           }
       }

       return PartialView("CoursesRegistration", model);
   }


   // saving changes here.
   static void SaveChanges(eNtsaCourses model)
   {

   }

Routes are resolved in the order you've added them so make sure your custom route is before the default route

routes.MapRoute(
    name: "CoursesRegistration",
    url: "courses-enrolled-for/",
    defaults: new { controller = "Home", action = "CoursesRegistration", url = UrlParameter.Optional }
);

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

If the default route is first it will take "courses-enrolled-for" as the controller name as the url matches the default pattern.

@F-ES Sitecore, my application is using AspNetIdentity, so below is my configuration from routing; // Route to CoursesRegistered
routes.MapRoute(
name: "CoursesRegistration",
url: "courses-enrolled-for/",
defaults: new { controller = "Home", action = "CoursesRegistration", url = UrlParameter.Optional }

);

// Route to home-page.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Account", action = "Index", id = UrlParameter.Optional }
); // This is used when used are registered/login on the site hope you get an idea

Well that config works for me, what is the url when you get a 404?

F-ES Sitecore 20-Aug-20 8:41am

Reading between the lines, are you submitting the form which is requiring authentication so you are directed to the login form then back to your action? If so that is your problem as your action is HttpPost and the redirect is an HttpGet. When you redirect to your url after login it doesn't preserve the original form data so you'll need an httpget version of the action that redirects to the original form. The user will have lost their data though so ensure the person is logged in when they access the form, not after they have submitted it.

In another words [HttpGet] public ActionResult(....) {}?

I have tried its work, the issue i get now is not saving to my table from the database

F-ES Sitecore 20-Aug-20 8:56am

Probably because the data isn't being submitted. If you are redirecting to that action from the login page there is no data in that request so your model will always be null. You have to submit from a form with method=post direct to your action.

If HttpGet is working and HttpPost is giving you a 404 that suggests your form is not doing a post to that action, somewhere along the way it is making a get instead. Look at my response to your new question so see why.
