ASP.NET MVC] Route match but controller never called. -> 404 - asp.net-mvc

Hi everyone I have a problem with MVC3 routing and areas:
My route matches but the controller is never called, instead i get a 404 error.
I have set an MVC3 solution with 2 project:
One is the main MVC Project: CityServices
One for an area: CityServices.Demo
In my area I register the following route:
public class TestAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "Test";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Test_default",
"Test/{controller}/{action}",
new { controller = "Stuff", action = "ListAll" }
);
}
}
Content of StuffController.cs:
public class StuffController : Controller
{
public ActionResult ListAll()
{
List<Stuff> lstStuff = new List<Stuff>
{
new Stuff()
{
Id = 0,
Name = "HEeey",
Value = 10.456f
},
new Stuff()
{
Id = 1,
Name = "Beeee",
Value = 456789.47879999f
},
new Stuff()
{
Id = 2,
Name = "HooAAaoo",
Value = 0f
}
};
return Json(lstStuff);
}
}
I register area in the main project:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
//RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);
}
My route is matched: http://host/Test
But i always get a 404 error.
Any ideas?
Thanks,
- Jeremy
Edit: Here is a proof that the route matches:
Found Solution
So to sum it up.
My AreaRegistration inherited class was not in the same namespace as my controllers.
Since i did not have any views (it's just a restful websvc) i did not have to use MvcContribs which seems to be useful when you have views&controllers in a differents project than the main site.
Hope this helps if you arrive on this question ;)

You have your area in another project which won't work per default unless you are using MvcContribs portable areas or another custom implementation

I think you need to set the allow get for json:
return Json(data, JsonRequestBehavior.AllowGet)

ASP.NET MVC - Attribute Routing not finding area view

I've been searching for answers for this everywhere, but I can't seem to find any. I basically have an MVC application setup and I am using the built in AttributeRouting for my routes.
The folder structure looks like this;
Models
Views
Controllers
Areas
Member
MemberAreaRegistration.cs
Controllers
HomeController.cs
Views
Home
Account.cshtml
And then I wire up my routes in the global.asax like this;
public class Application : System.Web.HttpApplication {
protected void Application_Start(){
AreaRegistration.RegisterAllAreas();
// other web optimization stuff
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
So then, MemberAreaRegistration.cs is simple.
namespace App.Web.Areas.Member {
public class MemberAreaRegistration: AreaRegistration {
public override string AreaName { get { return "Member"; } }
}
public override void RegisterArea( AreaRegistrationContext context){ }
}
And I try to wire it using the attributes...
/areas/member/controllers/homecontroller.cs
// ...
[Route("member/account")]
public ActionResult Account() { return View(); }
// ...
The problem is that this finds the route, but it cannot find the view. I get the following error;
The view 'Account' or its master was not found or no view engine
supports the searched locations. The following locations were
searched:
~/Views/Home/Account.aspx
~/Views/Home/Account.ascx
~/Views/Shared/Account.aspx
~/Views/Shared/Account.ascx
~/Views/Home/Account.cshtml
~/Views/Home/Account.vbhtml
~/Views/Shared/Account.cshtml
~/Views/Shared/Account.vbhtml
By all accounts, this should work fine - and if not, I expect the ~/area to at least be in the path it is trying to search. Do I have to wire something additional up to make this function?
I am using ASP.NET MVC 5.0
If I hardcode the absolute path of the view, it works. Obviously this is not a good situation though. I'd prefer it to find the view out of convention. But if I type return View("~/areas/member/views/home/account.cshtml"); I do get the view back - so I know it can access to file and that it is correct.
Here is my RouteConfig.cs per request
RouteConfig.cs
public class RouteConfig {
public static void RegisterRoutes(RouteCollection routes) {
// mvc attribute routing allows us to supersede normal routing mechanisms and
// declare our routes a bit more verbosely
routes.MapMvcAttributeRoutes();
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: new[] { "App.Web.Controllers" }
);
}
}
That's because, once you are defining your route as an action's attribute, ASP.NET MVC doesn't know which area it is in, hence it doesn't know where to look for Views.
In the Controller the Account action is in, try to explicitly specify a RouteArea attribute.
I'm writing this off the top of my head, but it should look like:
[RouteArea("Member")]
[RoutePrefix("member")]
public class HomeController: Controller {
[Route("account")]
public ActionResult Account() { return View(); }
}
or, alternatively:
[RouteArea("Member")]
public class HomeController: Controller {
[Route("member/account")]
public ActionResult Account() { return View(); }
}

MVC4 w/o WebAPI: Area routes return 404

I'm using MVC4 without WebAPI, just plain on MVC. I have an admin area (called "Admin", as usual) which is properly registered:
public class AdminAreaRegistration : AreaRegistration
{
public override string AreaName { get { return "Admin"; } }
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute("EditGroupRoute", "admin/groups/{action}/{id}", new { controller = "EditGroup", action = "Index", id = UrlParameter.Optional });
//...
//No default handler at the end, all routes are predetermined
}
Global.asax:
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
//...
}
}
My regular, non-area RouteConfig.RegisterRoutes works as it should and contains normal routes with no default catch-all handler at the end.
Whenever I try some admin area route I get a 404 error. I'm using Haack's RouteDebugger and it shows a full match (and only one match) below the 404 error text, with the correct area, controller and action.
I've checked similar questions on SO, but no joy. Any ideas what could be wrong?
Area controllers were in the wrong namespace. Originally they were in /Controllers when I moved them to area controllers I didn't update the namespaces.

MVC 3 - New Area - 404 error - Resource not found - have tried route debugger

I have a small MVC 3 app - bit of a demo ground.
I have one area and thats been working fine.
I have just added another area expecting to just spin up the app and it work - but no, 404 - The resource cannot be found.
The map route in the AreaRegistration is the default (as is the first area i created).
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Postcard_default",
"Postcard/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
I have tried adding in a specific controller into this, but nothing.
So I downloaded Phil Haack's RouteDebugger and my route is found when typing in http://server/Postcard/Create (which is where I am trying to get too)
Structure of the Area
My controller
public class CreateController : Controller
{
private ILogger Logger { get; set; }
private ICardSender Emailer { get; set; }
private IOCCardRepository CardRepository { get; set; }
public CreateController(ILogger logger, ICardSender cardSender, IOCCardRepository repository)
{
this.Logger = logger;
this.Emailer = cardSender;
this.CardRepository = repository;
}
//
// GET: /Postcard/Create/
public ActionResult Index()
{
var model = new OCPostcardModel().Create();
return View(model);
}
NOW: I have since deleted the entire area, tried again it didn't work. So I added in the specific controller in the route (Inside AreaRegistration file)
context.MapRoute(
"Postcard_default",
"Postcard/{controller}/{action}/{id}",
new { controller = "Create", action = "Index", id = UrlParameter.Optional }
);
And its working...I don't know why it didn't work when I did this before, but it is now.
Still curious though as I've not seen anyone add in this controller into route in any of the demo's i've looked at - and I haven't got it in my other area?
I ran into this when I moved a controller into an Area but forgot to update the namespace. The controller name is scoped to the Area's namespace. So "Some" in "Area" will map to App.Areas.Area.Controllers.SomeController, which didn't exist.
You were missing the controller part in your maproute
Try to add a class PostCardAreaRegistration under PostCard Area
using System.Web.Mvc;
namespace Areas.PostCard
{
public class PostCardAreaRegistration: AreaRegistration
{
public override string AreaName
{
get
{
return "PostCard";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"PostCard_default",
"PostCard/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
}
}

MVC 2 AreaRegistration Routes Order

I noticed that in MVC 2 Preview 2, AreaRegistration is loading the routes for each area in an arbitrary order. Is there a good way to get one before the other?
For example, I have two areas - "Site" and "Admin". Both have a "Blog" controller.
I would like the following:
/admin/ --> go to Admin's Blog controller
/ --> go to Site's Blog controller.
The problem is that it is loading the site's route first, so it is matching {controller}/{action}/{id} instead of admin/{controller}/{action}/{id} when I go to the url "/admin/". I then get a 404, because there is no Admin controller in the "Site" area.
Both areas default to the "Blog" controller. I realize I could simply put site/{controller}/... as the url, but I would rather have it at the root if possible. I also tried keeping the default route in the global RegisterRoutes function, however, it is then not sent to the "Sites" area.
Thanks in advance!
Aside from what Haacked said, it is very much possible to order area registrations (and thus their routes). All you have to do is register each area manually, in whatever order you want. It's not as sleek as calling RegisterAllAreas() but it's definitely doable.
protected void Application_Start() {
var area1reg = new Area1AreaRegistration();
var area1context = new AreaRegistrationContext(area1reg.AreaName, RouteTable.Routes);
area1reg.RegisterArea(area1context);
var area2reg = new Area2AreaRegistration();
var area2context = new AreaRegistrationContext(area2reg.AreaName, RouteTable.Routes);
area2reg.RegisterArea(area2context);
var area3reg = new Area3AreaRegistration();
var area3context = new AreaRegistrationContext(area3reg.AreaName, RouteTable.Routes);
area3reg.RegisterArea(area3context);
}
Another option is to take the code for RegisterAllAreas(), copy it into your own app, and build your own mechanism for determining the order. It is quite a bit of code to copy if you want all the fancy caching logic that the built-in method does, but your app might not even need that.
Currently it's not possible to order areas. However, I think it makes sense to try and make each area as independent from other areas as possible so the order doesn't matter.
For example, instead of having the default {controller}/{action}/{id} route, maybe replace that with specific routes for each controller. Or add a constraint to that default route.
We are mulling over options to allow ordering, but we don't want to overcomplicate the feature.
I make this solution:
AreaUtils.cs
using System;
using System.Web.Mvc;
using System.Web.Routing;
namespace SledgeHammer.Mvc.Site
{
public static class Utils
{
public static void RegisterArea<T>(RouteCollection routes,
object state) where T : AreaRegistration
{
AreaRegistration registration =
(AreaRegistration)Activator.CreateInstance(typeof(T));
AreaRegistrationContext context =
new AreaRegistrationContext(registration.AreaName, routes, state);
string tNamespace = registration.GetType().Namespace;
if (tNamespace != null)
{
context.Namespaces.Add(tNamespace + ".*");
}
registration.RegisterArea(context);
}
}
}
In global.asax:
Utils.RegisterArea<SystemAreaRegistration>(RouteTable.Routes, null);
Utils.RegisterArea<ClientSitesAreaRegistration>(RouteTable.Routes, null);
//AreaRegistration.RegisterAllAreas(); do not dublicate register areas
No requred changes to generated area registration code.
I also use custom constrant in routes to filter routes by type of domain in request (system domain or user site).
This is my area registrations as example:
namespace SledgeHammer.MVC.Site.Areas.System
{
public class SystemAreaRegistration : AreaRegistration
{
public override string AreaName
{
get { return "System"; }
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"System_Feedback",
"Feedback",
new { controller = "Feedback", action = "Index" }
);
context.MapRoute(
"System_Information",
"Information/{action}/{id}",
new { controller = "Information", action = "Index", id = UrlParameter.Optional }
);
}
}
}
namespace SledgeHammer.MVC.Site.Areas.ClientSites
{
public class ClientSitesAreaRegistration : AreaRegistration
{
public override string AreaName
{
get { return "ClientSites"; }
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"ClientSites_default",
"{controller}/{action}/{id}",
new { controller = "Site", action = "Index", id = UrlParameter.Optional },
new { Host = new SiteInGroups("clients") }
);
}
}
}
For reference,
In MVC3 (don't know about MVC2) when you just want to map root to a specific area/controller you could simply use a global route.
Just remember to specify the namespace/area.
routes.MapRoute(
"CatchRoot", "",
new { controller = "SITEBLOG-CONTROLLER-NAME", action = "Index"}
).DataTokens.Add("area", "SITE-AREA-NAME");

ASP.NET MVC Routing Question

I must be dense. After asking several questions on StackOverflow, I am still at a loss when it comes to grasping the new routing engine provided with ASP.NET MVC. I think I've narrowed down the problem to a very simple one, which, if solved, would probably allow me to solve the rest of my routing issues. So here it is:
How would you register a route to support a Twitter-like URL for user profiles?
www.twitter.com/username
Assume the need to also support:
the default {controller}/{action}/{id} route.
URLs like:
www.twitter.com/login
www.twitter.com/register
Is this possible?
What about
routes.MapRoute(
"Profiles",
"{userName}",
new { controller = "Profiles", action = "ShowUser" }
);
and then, in ProfilesController, there would be a function
public ActionResult ShowUser(string userName)
{
...
In the function, if no user with the specified userName is found, you should redirect to the default {controller}/{action}/{id} (here, it would be just {controller}) route.
Urls like www.twitter.com/login should be registered before that one.
routes.MapRoute(
"Login",
"Login",
new { controller = "Security", action = "Login" }
);
The important thing to understand is that the routes are matched in the order they are registered. So you would need to register the most specific route first, and the most general last, or all requests matching the general route would never reach the more specific route.
For your problem i would register routing rules for each of the special pages, like "register" and "login" before the username rule.
You could handle that in the home controller, but the controller method would not be very elegant. I'm guessing something like this might work (not tested):
routes.MapRoute(
"Root",
"{controller}/{view}",
new { controller = "Home", action = "Index", view = "" }
);
Then in your HomeController:
public ActionResult Index(string view) {
switch (view) {
case "":
return View();
case "register":
return View("Register");
default:
// load user profile view
}
}
OK I haven't ever properly tried this, but have you tried to extend the RouteBase class for dealing with users. The docs for RouteBase suggest that the method GetRouteData should return null if it doesn't match the current request. You could use this to check that the request matches one of the usernames you have.
You can add a RouteBase subclass using:
routes.Add(new UserRouteBase());
When you register the routes.
Might be worth investigating.
i think your question is similar to mine. ASP.NET MVC Routing
this is what robert harvey answered.
routes.MapRoute( _
"SearchRoute", _
"{id}", _
New With {.controller = "User", .action = "Profile", .id = ""} _
)
Here is an alternative way to standar route registration:
1. Download RiaLibrary.Web.dll and reference it in your ASP.NET MVC website project
2. Decoreate controller methods with the [Url] Attributes:
public SiteController : Controller
{
[Url("")]
public ActionResult Home()
{
return View();
}
[Url("about")]
public ActionResult AboutUs()
{
return View();
}
[Url("store/{?category}")]
public ActionResult Products(string category = null)
{
return View();
}
}
BTW, '?' sign in '{?category}' parameter means that it's optional. You won't need to specify this explicitly in route defaults, which is equals to this:
routes.MapRoute("Store", "store/{category}",
new { controller = "Store", action = "Home", category = UrlParameter.Optional });
3. Update Global.asax.cs file
public class MvcApplication : System.Web.HttpApplication
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoutes(); // This do the trick
}
protected void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
}
How to set defaults and constraints? Example:
public SiteController : Controller
{
[Url("admin/articles/edit/{id}", Constraints = #"id=\d+")]
public ActionResult ArticlesEdit(int id)
{
return View();
}
[Url("articles/{category}/{date}_{title}", Constraints =
"date=(19|20)\d\d-(0[1-9]|1[012])-(0[1-9]|[12][0-9]|3[01])")]
public ActionResult Article(string category, DateTime date, string title)
{
return View();
}
}
How to set ordering? Example:
[Url("forums/{?category}", Order = 2)]
public ActionResult Threads(string category)
{
return View();
}
[Url("forums/new", Order = 1)]
public ActionResult NewThread()
{
return View();
}
