I’ve already researched it, I’ve spent two hours burning the dog but I couldn’t find a solution. Has anyone ever had that problem?

I have the following link:

http://localhost:49609/Manufacturer/Editarregistro/53/1/4/G/3/13

Controller -> Fabricante
Action -> EditarRegistro
Param01 ->53
Param02 ->1
Param03 ->4
...
Param05 -> 13.

My route is configured as follows:

  ///ROTAS PARA FABRICANTE
            routes.MapRoute(
                    name: "EditarFabricante",
                    url: "{controller}/" +
                         "{action}/" +
                         "{org_tab_in_codigo}/" +
                         "{org_pad_in_Codigo}/" +
                         "{org_in_codigo}/" +
                         "{Org_Tau_In_Codigo}/" +
                         "{vFab_In_Codigo}/" +
                         "{Alf_In_codigo}",
                    defaults: new
                    {
                        controller = "Fabricante",
                        action = "EditarRegistro",
                        org_tab_in_codigo = UrlParameter.Optional,
                        org_pad_in_Codigo = UrlParameter.Optional,
                        org_in_codigo = UrlParameter.Optional,
                        Org_Tau_In_Codigo = UrlParameter.Optional,
                        vFab_In_Codigo = UrlParameter.Optional,
                        Alf_In_codigo = UrlParameter.Optional
                    });

Man controller is configured:

    [Route("EditarFabricante")]
    public ActionResult EditarRegistro(int Org_Tab_In_Codigo,
                                       int Org_Pad_In_Codigo,
                                       int Org_In_Codigo,
                                       string Org_Tau_In_Codigo,
                                       string vFab_In_Codigo,
                                       int Alf_In_Codigo)
    {
        ViewBag.NotView = ViewData.vNotView;
        var appFabricante = new WebEstFabricanteAplicacao();
        var webFabricante = appFabricante.ListarUmRegistrodaOrganizacao(Org_Tab_In_Codigo,
                                                                        Org_Pad_In_Codigo,
                                                                        Org_In_Codigo,
                                                                        Org_Tau_In_Codigo,
                                                                        int.Parse(vFab_In_Codigo.ToString()),
                                                                        Alf_In_Codigo);

        return View(webFabricante);
    }

[EDIT]

Man button to edit the record is as follows:

                                                       <a href="@Url.RouteUrl("EditarFabricante", 
                                    new {action = "EditarRegistro",
                                    org_tab_in_codigo = item.Org_Tab_In_Codigo,
                                    org_pad_in_Codigo = item.Org_Pad_In_Codigo,
                                    org_in_codigo = item.Org_In_Codigo,
                                    Org_Tau_In_Codigo = item.Org_Tau_St_Codigo,
                                    vFab_In_Codigo = item.Fab_In_Codigo,
                                    Alf_In_codigo = item.Alf_In_Codigo})"
                               title="Editar Registro"
                               onclick="Loading();"
                               class="btn btn-primary">
                                <i class="fa fa-edit"></i>
                            </a>

[/EDIT]

By clicking on button it presents the error: Erro

I can’t decipher because damn, my controller is taking the value of vFAB_IN_CODIGO as null, and it is identified in the URL.

[EDITION]

Now I discovered that the problem occurs in the second ROUTE created, when I call the first custom ROUTE the system performs normally, but when executing another ROUTE with the same parameters the system displays the null parameter error.

        ///ROTAS PARA FABRICANTE
        routes.MapRoute(
                name: "EditarFabricante",
                url: "{controller}/" +
                     "{action}/" +
                     "{org_tab_in_codigo}/" +
                     "{org_pad_in_Codigo}/" +
                     "{org_in_codigo}/" +
                     "{Org_Tau_In_Codigo}/" +
                     "{vFab_In_Codigo}/" +
                     "{Alf_In_codigo}",
                defaults: new
                {
                    controller = "Fabricante",
                    action = "EditarRegistro",
                    org_tab_in_codigo = UrlParameter.Optional,
                    org_pad_in_Codigo = UrlParameter.Optional,
                    org_in_codigo = UrlParameter.Optional,
                    Org_Tau_In_Codigo = UrlParameter.Optional,
                    vFab_In_Codigo = UrlParameter.Optional,
                    Alf_In_codigo = UrlParameter.Optional
                });


        routes.MapRoute(
                name: "ExcluirFabricante",
                url: "{controller}/{action}/{org_tab_in_codigo}/{org_pad_in_Codigo}/{org_in_codigo}/{Org_Tau_In_Codigo}/{vFab_In_Codigo}/{Alf_In_codigo}",
                defaults: new
                {
                    controller = "Fabricante",
                    action = "ExcluirRegistro",
                    org_tab_in_codigo = UrlParameter.Optional,
                    org_pad_in_Codigo = UrlParameter.Optional,
                    org_in_codigo = UrlParameter.Optional,
                    Org_Tau_In_Codigo = UrlParameter.Optional,
                    vFab_In_Codigo = UrlParameter.Optional,
                    Alf_In_codigo = UrlParameter.Optional
                });

Running the first route:

When clicking normally calls to the edit ROUTE. inserir a descrição da imagem aqui

Now by clicking delete which calls the second route with the same parameters, but Action different from the error.

I’m doing it wrong?

[/EDITION]

c# url laravel-routes

  • Tried instead of getting string vFab_In_Codigo receive int vFab_In_Codigo. In the error message it says that it is not coming whole, maybe for some reason(supernatural) it is not converting int to string

  • In fact he is int I put it as a string to check the value that was returning, but it always returns as null. [link]https://imgur.com/a/g34oyD6

  • vFab_In_Codigo is int or int? ???

  • "int", as it is a record edit button it has to pass the/ composed keys to find this record in the database.

  • and you noticed that in the view you assign item.Org_Tau_St_Codigo for Org_Tau_In_Codigo, Is this difference in name right? I built your structure here and got no error.

  • Leandro, I verified that the problem occurs in the second route onwards. I edited the post with some new details that I detected.

  • The two routes have the same number of parameters; how do you think MVC will be able to solve which is which?

  • Marcelo thinking about what you said, I reached another conclusion/solution. I will post the {GATO} that was made to work this.

I came to this solution, I’m not sure if it’s the right pooooorem....

I modified the two ROUTES:

        ///ROTAS PARA FABRICANTE
        routes.MapRoute(
                name: "EditarFabricante",
                url: "{controller}/" +
                     "{action}/" +
                     "{org_tab_in_codigo}/" +
                     "{org_pad_in_Codigo}/" +
                     "{org_in_codigo}/" +
                     "{org_tau_in_codigo}/" +
                     "{fab_in_codigo}/" +
                     "{alf_in_codigo}",
                defaults: new
                {
                    controller = "Fabricante",
                    action = "EditarRegistro"
                });


        routes.MapRoute(
                name: "ExcluirFabricante",
                url: "{controller}/" +
                     "{action}/" +
                     "{org_tab_in_codigo}/" +
                     "{org_pad_in_Codigo}/" +
                     "{org_in_codigo}/" +
                     "{org_tau_in_codigo}/" +
                     "{fab_in_codigo}/" +
                     "{alf_in_codigo}",
                defaults: new
                {
                    controller = "Fabricante",
                    action = "ExcluirRegistro"
                });

Before I was passing the parameters directly on ROUTE, removed the parameters keeping the URL normally. Now I do the route modification directly on controller.

[Route("Fabricante/Editarregistro/{org_tab_in_codigo}/{org_pad_in_Codigo}/{org_in_codigo}/{org_tau_in_codigo}/{fab_in_codigo}/{alf_in_codigo}")]

    [Route("Fabricante/EditarRegistro/{org_tab_in_codigo}/{org_pad_in_Codigo}/{org_in_codigo}/{org_tau_in_codigo}/{fab_in_codigo}/{alf_in_codigo}")]
public ActionResult EditarRegistro(int org_tab_in_codigo,
                                           int org_pad_in_Codigo,
                                           int org_in_codigo,
                                           string org_tau_in_codigo,
                                           int fab_in_codigo,
                                           int alf_in_codigo)
        {
            ViewBag.NotView = ViewData.vNotView;
            var appFabricante = new WebEstFabricanteAplicacao();
            var webFabricante = appFabricante.ListarUmRegistrodaOrganizacao(org_tab_in_codigo,
                                                                            org_pad_in_Codigo,
                                                                            org_in_codigo,
                                                                            org_tau_in_codigo,
                                                                            fab_in_codigo,
                                                                            alf_in_codigo);

            return View(webFabricante);
        }

So he accepted the ROUTES :

http://localhost:49609/Manufacturer/Editarregistro/53/1/4/G/3/13

http://localhost:49609/Manufacturer/Exclurregistro/53/1/4/G/3/13

And not getting lost and passing null value to integer parameter.

Thank you all.
