If I have the following MapRoute:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
I can have an url like:
blabla.com/Home/Index/123
But what kind of MapRoute do I need to create to be able to do this:
blabla.com/Home/123 or blabla.com/Home/DEADBEEF?
I imagine it involves something along the lines of
"{controller}/{id}/{action}"
Action and id are reversed, and maybe there should be a default action. But how will the MapRoute know which controller should be treated like this?
You probably need something along these lines.
routes.MapRoute(
name: "DefaultRoute",
url: "Home/{action}",
defaults: new { controller = "Home", action = "Index" },
constraints: new { action = "[A-Za-z]*" }
);
or without an action
routes.MapRoute(
name: "DefaultRoute",
url: "Home/{id}",
defaults: new { controller = "Home", action = "Index", id = "" },
constraints: new { id = "[A-Za-z]*" }
);
You will need to make sure that the route name is different than any other routes you have setup and pay attention to the ordering of the routes as other routes that are similar can override each other. In this case make sure you would probably want this before the default route but be aware that it will override it.
As for the not having controller or even the action you can set defaults and do not need them within the route.
As for constraints you can simply add the constraints parameter to the route to set a regular expression for a certain attribute as shown above.

You can add a route like this:
routes.MapRoute(
"CustomRoute",
"Home/{id}",
new { controller = "Home", action = "Index", id = "" });
Make sure you place it above the default route. However this route will block all the other actions in HomeController. Since we don't have a constraint on id parameter, the framework can't possibly know if you are referring to an action or an id in your URL. Since this route comes first, it will map it to id parameter.

Given this URL's
http://localhost:51095/Person // This is equivalent to this one Person/Index
http://localhost:51095/Person/Allan
I setup a route config for it as follows :
routes.MapRoute(
"Person",
"Person/{personName}",
new { controller = "Person", action = "Person", personName = UrlParameter.Optional }
)
;
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
First URL should follow the Default route and the second should follow the Person route.
This is not working because the first config seems to catch all these URL's
The first thing I'd do is remove personName = UrlParameter.Optional in the first Route. This would allow only urls that provide a personName value to access this Route. If no value is provided, it should fall through to the default Route.
But you'd want to think about the future with this strategy: if you implement new actions on that Person controller, you'd need to add a new Route for each of them. If you had a new 'Edit' action for example:
routes.MapRoute(
"Person_Edit",
"Person/Edit/{personName}",
new { controller = "Person", action = "Edit" }
)
You'd want to add these new Routes before the first one though - ordering/precedence of Routes is important.
Let's look at these two routes mapped in RouteConfig.cs, one with a guid and one without:
// Non-guid route
routes.MapPageRoute(
name: null,
url: "dashboard/{action}",
defaults: new { controller = "Dashboard", action = "Index" }
);
// Guid route
routes.MapPageRoute(
name: null,
url: "{guid}/dashboard/{action}",
defaults: new { controller = "Dashboard", action = "Index" }
);
And the method call:
UrlHelper.Action("Index", "Dashboard", new { guid = "c73b47b9-4ad5-414a-a92e-8937231f8e2bD" })
The method returns this:
"/dashboard/?guid=c73b47b9-4ad5-414a-a92e-8937231f8e2b"
But I'm expecting this:
"/c73b47b9-4ad5-414a-a92e-8937231f8e2b/dashboard/"
Note that it's putting the guid as a querystring value instead of the first parameter.
Now if I hardcode that second url the app uses the correct guid route and also works if I use route names instead (UrlHelper.RouteUrl) so I don't think it's an issue with the route mappings themselves. Neither of these solutions will work well with our application as we have hundreds of routes and currently using UrlHelper.Action all over the place.
I've also tried pretty much every overload and variation of UrlHelper.Action, including passing a RouteValueDictionary instead of an anonymous object.
This is an ASP.NET MVC 4 web application.
Any ideas to why this isn't working? (or alternatives, maybe using one route)
Try this. Put the more specific route first:
routes.MapRoute(
name: "WithGUID",
url: "{guid}/dashboard/{action}",
defaults: new { controller = "Dashboard", action = "Index" }
);
routes.MapRoute(
name: "NoGUID",
url: "dashboard/{action}",
defaults: new { controller = "Dashboard", action = "Index", guid = "" }
);
I have a request controller that is getting out of hand, and I want to divide the actions on several controllers while maintaining a clean URL. I'm trying to experiment with routing, but without success. I've read some examples and tutorials on routing, but, though I understand the examples, nothing seems to apply to my case, and I feel non the wiser. What I want is for the URL Requests/Approval to be handled on my ApprovalController instead of my RequestController, so I wrote the following.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Approval",
"Request/{controller}/{action}",
new { controller = "Approval", action="Index", id = "" }
);
}
But it's not working. Why? I have a folder in the my Views called Approval, and in there I have a file called Index.cshtml. How should I code the MapRoute?
Edit
I added all the routes I've got
You need to swap the two MapRoute statements, like so:
routes.MapRoute(
"Approval",
"Request/Approval/{action}",
new { controller = "Approval", action="Index", id = "" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
The reason it is currently not working is because the first statement ('Default' route name) is getting matched before the second one is even evaluated.
In addition (as noted in my above example,) you need to remove '{controller}' in the Approval route and replace with 'Approval'... unless you specifically want the URL /Request/{ANY controller}/{action} to go through, which I doubt. From your question it seems you only want /Request/Approval/ to go to your Approval controller.
Don't forget to keep the Default route at the bottom, so as to match your other controllers and actions. It serves as a catch-all should no other matches exist.
The order you map your routes matters. Move the second route before the default route.
You will still have a problem though, as any thing /request/something will look for the SomethingContoller. To fix this, change your route to this:
routes.MapRoute(
"Approval",
"Request/Approval/{action}",
new { controller = "Approval", action="Index", id = "" }
);
I need to access a parameter without name.
Ex: I have a controller test, I want to get "data" in mysite.com/test/data. Without calling the action data.
I know how to do that passing it though Index action.
public ActionResult Index(string id)
That way I'd only need to type mysite.com/test/Index/data to get "data", but I don't want to have to type Index.
Does anyone know how to do it?
EDIT:
Thanks a lot to #andyc!
AndyC I used what you said and created a test. It worked =D
Now I can type mysite.com/something and if something is not an controller it redirects to my profile page.
This is what is working for me
routes.MapRoute(
"Profile",
"{id}",
new { Controller = "Profile", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
Setup a custom route
In your global.asax file, put (Inside the RegisterRoutes method):
routes.MapRoute(
"MyShortRoute",
"view/{id}",
new { Controller = "test", action = "Index" }
);
The first parameter is a name, the second is the URL format and the last parameter is the default values (in this case if you leave id empty it'll default to id 0.
Notice that I don't use test/{id} as this would also match test/Edit, where edit is an action that you do not want passed as a parameter (I can't think of another way to avoid this, especially if you're using strings instead of ints for your parameters).
Remember to order your routes appropriately in your global.asax file. Put more specific routes before less specific routes. When the system is searching for a route to take, it does not attempt to find the most specific match but instead it starts from the top, and uses the first match it finds.
Therefore, this is bad:
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "test", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"Specific",
"test/{id}",
new { controller = "test", action = "Index", id = 0 }
);
In this example, if you browse to test/somevalue it will match the FIRST entry, which is not what you want, giving you the testcontroller and the somevalue action.
(As your adding a more specific route, you will want it near the top, and definitely before your default).
How do I generate friendly URLs within the ASP.NET MVC Framework? For example, we've got a URL that looks like this:
http://site/catalogue/BrowseByStyleLevel/1
The 1 is Id of the study level (Higher in this case) to browse, but I'l like to reformat the URL in the same way StackOverflow does it.
For example, these two URLs will take you to the same place:
https://stackoverflow.com/questions/119323/nested-for-loops-in-different-languages
https://stackoverflow.com/questions/119323/
EDIT: The friendly part of the url is referred to as a slug.
There are two steps to solve this problem. First, create a new route or change the default route to accept an additional parameter:
routes.MapRoute( "Default", // Route name
"{controller}/{action}/{id}/{ignoreThisBit}",
new { controller = "Home",
action = "Index",
id = "",
ignoreThisBit = ""} // Parameter defaults )
Now you can type whatever you want to at the end of your URI and the application will ignore it.
When you render the links, you need to add the "friendly" text:
<%= Html.ActionLink("Link text", "ActionName", "ControllerName",
new { id = 1234, ignoreThisBit="friendly-text-here" });
This is how I have implemented the slug URL on my application.
Note: The default Maproute should not be changed and also the routes are processed in the order in which they're added to the route list.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home",
action = "Index",
id = UrlParameter.Optional
} // Parameter defaults
);
routes.MapRoute("Place", "{controller}/{action}/{id}/{slug}", new { controller = "Place", action = "Details", id = UrlParameter.Optional,slug="" });
you have a route on the global.asax
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = ""}
// Parameter defaults )
you can define your own route like :
controller is the cs class inside the the controllers folder.
you can define your id - with the name you choose.
the system will pass the value to your actionResult method.
