Question

resource cannot be found issue

rob m 261

I have an entity framework app I am rehabilitating.
all the routes work just the one labeled details fails with the error below.

Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /Survey/Details/3

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.8.4330.0

see image below the web page is there I cannot figure out how to debug this issue ?

You misunderstand the error and most likely MVC fundamentals. In MV,C the URL maps to an Action not a View. An action returns a View but the Action was not found.

Can you share the controller and route configuration?

not sure if this is what you are asking about.

public static class WebApiConfig  
{  
     [EnableCors(origins: "https://www.comap.ca", headers: "*", methods: "*")]  
    public static void Register(HttpConfiguration config)  
    {  
        //ENABLE CORS   
        config.EnableCors();  

        config.Routes.MapHttpRoute(  
            name: "DefaultApi",  
            routeTemplate: "api/{controller}/{id}",  
            defaults: new { id = RouteParameter.Optional }  
        );  
    }  
}

I think this is what you are looking for.

namespace SWAT
{
public static class WebApiConfig
{
[EnableCors(origins: "https://www.comap.ca", headers: "", methods: "")]
public static void Register(HttpConfiguration config)
{
//ENABLE CORS
config.EnableCors();

config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); } }

}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;

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

            routes.MapRoute(
                 "CountriesList",
                 "Location/Countries/List/{regionID}",
                 new { controller = "Location", action = "CountryList", regionID = UrlParameter.Optional }

            routes.MapRoute(

Hi @rob m ,
Yes. According to your maproute, if you want to run the details page,it will run this:

url: "{controller}/{action}/{id}"

And then you need to check your controller and action. In your images,I think your url need to like this:

/User/Details/3

Hi @rob m ,I think you don't understand my meanings. According to your controller file name and routemap in your posting, your route url need like this:url: "{controller}/{action}/{id}". Because you only give us the user controller,so I make a example of user. If your problem is survey, you must to check if you have the surveycontroller and details action. You also could break point the action and routemap to check if the codes run.

rob m 261

OK

so should I be updating RouteConfig

         routes.MapRoute(
              "SurveyList",
              "Survey/Details/List/{id}",
              new { controller = "Survey", action = "Detail", id = UrlParameter.Optional }
         );

Hi @rob m ,

Your problem is if you have the file of the survey controller and the details action. Could you post the controller to us? Of course, if you have the file,you could change the maproute .routes.MapRoute( "SurveyList", "Survey/Details/{id}", new { controller = "Survey", action = "Detail", id = UrlParameter.Optional } );

Is there an explanation for this error in layman’s terms?

I have NO IDEA what your technical coding means or how to access it and follow your instructions.

Thank you,

Are you sure the namespace for the view Details is viable and namespaces in the view are viable? What about in JavaScript pathing used by the view is viable?

java seems fine

@默 SWAT.Models.tblSWATSurvey

@{ ViewBag.Title = "Details"; }

@section Scripts
{
<script src="@URL .Content("~/Scripts/jquery-2.1.0.min.js")" type="text/javascript"></script>
<script src="@URL .Content("~/Scripts/Highcharts-3.0.1/js/highcharts.js")" type="text/javascript"></script>

@Scripts.Render("~/Content/session.js")

}

Hi @rob m ,
As far as I think, the most common problem of 404 is your request URL isn't match the route url.
If it is convenient, can you provide your routing configuration (RouteConfig)? By default,the url is like this

"{controller}/{action}/{id}"

Through the information you provide, your request url is this:

/User/Details/3

By the way,you should note wheather there are spelling errors.

one spelling error and two grammar errors. They are identified with a red underline, as seen in my comment. Hopefully, when I submit my post, they won’t be auto corrected.

So I’m posting them each for your information:

way,you: needs a space between the comma after the word “way” and the word “you.”

“wheather” is spelled “whether,” in this context; otherwise, for the outdoor conditions, use the word “weather.”

Hope this helps! I mean no offense or disrespect. I thought you would like to be aware of this because you stated, “…you should note wheather there are spelling errors.”

Respectfully,
