When I enter the registration details by the ID index it is always null.

http://localhost:17542/Availability/Details/0

Controller Details:

public ActionResult Detalhes(int? id)
        {
            var disponibilidade = db.Disponibilidade.Where(d => d.DisponibilidadeID == id).FirstOrDefault();

            if (disponibilidade == null)
            {
                return new HttpNotFoundResult();
            }
            DisponibilidadeViewModel model = new DisponibilidadeViewModel()
            {     
                AnoPastoral = disponibilidade.AnoPastoral,
                DiaDisponivel = disponibilidade.DiaDisponivel,
                HoraDisponivel = disponibilidade.HoraDisponivel,
                Observacoes = disponibilidade.Observacoes
            }; 
            return View(model);
        }

Create controller:

public ActionResult CriarDisponibilidade([Bind(Include = "DisponibilidadeID,AnoPastoral,DiaDisponivel,HoraDisponivel,Observacoes,CatequistaID")] Disponibilidade disponibilidade)
        {
            if (ModelState.IsValid)
            {
                db.Disponibilidade.Add(disponibilidade);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(disponibilidade);
        }

Action Index:

@model IEnumerable<WebAppCatechesis2.ViewModels.DisponibilidadeViewModel>

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_mytemplate.cshtml";
}

<div id="page-wrapper">

        </div>
        <!-- /.col-lg-6 -->

</div>

Viewmodel:

 public class DisponibilidadeViewModel
    {
        public int DisponibilidadeID { get; set; }
        public String Nome { get; set; }
        public String AnoPastoral { get; set; }
        public String DiaDisponivel { get; set; }
        public String HoraDisponivel { get; set; }
        public String Observacoes { get; set; }
    }

You can put in your question how you are doing to call this URL?

The link is called a View associated with DisponibilidadeController? You should not go ID 0. Can you tell me why the link is being generated with this ID 0?

– Leonel Sanches da Silva

2015/12/15 at 20:12
If the id is manually placed in the url it works perfectly. But I don’t understand why it is 0.

– Simão Lopes

2015/12/15 at 20:15
Yes, the problem is obviously the link. You can put in your question to Action that saves an availability?

– Leonel Sanches da Silva

2015/12/15 at 20:19
My availabilities are being stored correctly. With the correct Ids.I will put the complete View.

If you’re wearing one Viewmodel for their Views, need to fill in DisponibilidadeID, otherwise it obviously won’t work:

        DisponibilidadeViewModel model = new DisponibilidadeViewModel()
        {   
            DisponibilidadeID = disponibilidade.DisponibilidadeID,
            AnoPastoral = disponibilidade.AnoPastoral,
            DiaDisponivel = disponibilidade.DiaDisponivel,
            HoraDisponivel = disponibilidade.HoraDisponivel,
            Observacoes = disponibilidade.Observacoes
        };

Controller problem Index:

Select new DisponibilidadeViewModel { Nome = p.Nome, DisponibilidadeID = d.DisponibilidadeID, AnoPastoral = d.AnoPastoral, DiaDisponivel = d.DiaDisponivel, HoraDisponivel = d.HoraDisponivel, Observacoes = d.Observacoes });

Was missing: DisponibilidadeID = d.DisponibilidadeID

Had already done this, the problem is that when I click on the Index Details it does not enter the method "Actionresult Details".

I’m gonna need the Action Index in your question too.

– Leonel Sanches da Silva

2015/12/15 at 21:15
It was amended with the Action Index, and Model View

– Simão Lopes

2015/12/15 at 21:25
So that’s it. You’re not filling in DisponibilidadeID, therefore the mistake.

– Leonel Sanches da Silva

2015/12/15 at 21:27
How can I fill this in Viewmodel?

– Simão Lopes

2015/12/15 at 21:33
I have already put this in my answer. It is not yet clear?

– Leonel Sanches da Silva

DisponibilidadeID = disponibilidade.DisponibilidadeID,, this field is only filled in if you place the ID in the URL.

– Simão Lopes

2015/12/15 at 21:51
var disponibilidade = db.Disponibilidade.Where(d => d.DisponibilidadeID == id).FirstOrDefault();,is the NULL and I can’t get around this.

– Simão Lopes

2015/12/15 at 21:57
I don’t think you understand. The wrong fill is in Index. Not in Details. In Details it’s all right.

– Leonel Sanches da Silva

2015/12/15 at 22:03
Sorry. OK I’ve figured out my problem.

In my experience I can tell you the following.

If you change the URL to :

http://localhost:17542/Availability/Details? id=0

It’ll work the way it is...

Now, to make this question URL work just put the following line in the file Route.Config.cs

        routes.MapMvcAttributeRoutes();

Would look like this:

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapMvcAttributeRoutes();


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

And put the following annotation in your method:

    [Route("seucontrole/detalhes/{id}")]

With that the route with /0 works.
