I have a multi tenant system and I need to allow administrators to edit the information of other customers.
I believe the correct way to do this is to append the customer ID to each request, and update my routes accordingly.
How do I make ASP.NET accept and use something like this in the controller (order doesn't mean much to me):
mysite.com/files/delete/{file}/{customerID}
and how would I pass and consume that in my controller? The ASP.NET tutorials skip this... (or I don't know where to search)
Define a route:
//mysite.com/files/delete/{file}/{customerID}
routes.MapRoute(
"Files", // Route name
"files/delete/{file}/{customerID}", // URL with parameters
new { controller = "File", action = "Delete" } // Parameter defaults
);
Create a Controller:
public class FileController : Controller
{
public ActionResult Delete(string file, string customerID)
{
//do something
return View();
}
}
I presume that {file} is a filename that should be deleted.

I want to override search controller. When I try to install a plugin, I get an error exception what multiple type were found for the controller named Catalog.
Multiple types were found that match the controller named 'Catalog'. This can happen if the route that services this request ('AdvanceSearch') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.
And my route priority is most(100).
public void RegisterRoutes(RouteCollection routes)
{
// Product Search,
routes.MapRoute("Plugin.Misc.Twigoh.Search",
"Search",
new { controller = "Catalog", action = "Search" },
new[] { "Nop.Plugin.Misc.Twigoh.Search.Controllers" });
}
public int Priority
{
get
{
return 100;
}
}
You can override your route like this:
When you override route, then you should use MapLocalizedRoute(not MapRoute) which is override localized route. Here you are trying to define route which is already define.
Here do not use MapRoute use MapLocalizedRoute in this way.
routes.MapLocalizedRoute("Plugin.Misc.Twigoh.Search",
"search/",
new { controller = "Catalog", action = "Search" },
new[] { "Nop.Plugin.Misc.Twigoh.Search.Controllers" });
Edit:
I want same route and functionality but default controller can't have
"/" search feature little bit different
/search is default route of product search, you can see in Nop.Web > Infrastructure > RouteProvider.cs
Hope this helps!
May be you rename your project so that the file name of the assembly changes, it's possible for you to have two versions.
So remove old .dll from bin folder and build your project.
I am creating a asp.net mvc 4 application
public class AspNetController : Controller
{
//
// GET: /AspNet/
public ActionResult Index()
{
return View();
}
public ActionResult Introduction()
{
return View();
}
}
as Shown Above There is AspNet Controller and Introduction Action Method
Default Url for Introduction Action Method is
localhost:55134/aspnet/introduction
But I Want Url Like
localhost:55134/aspnet/introduction-To-AspNet
Same for
/localhost:55134/aspnet/NetFrameWork To
/localhost:55134/aspnet/What-is-.Net-Framework
How to do that
You should be able to use the ActionName attribute to decorate your routes.
[ActionName("Introduction-To-AspNet")]
public ActionResult Introduction()
{
return View();
}
You really want to use AttributeRouting, either via a 3rd party package or natively if you can.
Technically this concept comes under Routing in ASP.NET MVC.
For this you need to do an entry for route in App_Start->RouteConfig.cs file under RegisterRoutes(RouteCollection routes)
For Example:
routes.MapRoute(
"customRouteName",
"aspnet/introduction-To-AspNet",
new { controller = "AspNet", action = "Introduction" });
here aspnet/introduction-To-AspNet will append after your base url i.e. localhost:55134/
The quick and dirty answer is to add a route to your ~/AppStart/RouteConfig.cs file and it will be taken care of:
routes.MapRoute(
name: "CustomRoute",
url: "Aspnet/Introduction-To-AspNet",
defaults: new { controller = "Home", action = "AspNet", id = UrlParameter.Optional }
);
However, I'm assuming this is for some type of blog? I would reccomend that you have an action method called view, and then use your name as a parameter for the article. That way, you don't have to go in and edit the code every time you add a new article or other content:
public class ArticlesController : Controller
{
public ActionResult ViewArticle(string? title)
{
ViewBag.Article = title;
return View();
}
}
that way, your URL would be www.yoursite.com/Articles/ViewArticle/Introduction-To-AspNet. In general, you don't want to add tons of specific routes to your route config if you can avoid it. That being said, if this is a legacy system, the route table may be the only way.
EDIT
Ok, so what you can do is pass the string into the ViewBag and use a case statement to determine which partial view to show (I think this just might be your ideal solution):
<!--cshtml view-->
#switch(ViewBag.Article)
{
case 'Introduction-To-AspNet':
#Html.Partial('pathToPartialView.cshtml')
break;
case 'Some-Other-Article'
#Html.Partial('pathToAnotherPartialView.cshtml')
break;
...
...
default:
#Html.Partial('invalidArticleName.cshtml')
break;
}
The controller will pass the article name through the ViewBagand then you can use the case statement to figure out which article to render... and of course, the real secret sauce you've been looking for: #Html.Partial('URL') - this will take your partial and render it right were you put that in the page. You can also pass objects to that just as an FYI.
In addition, make sure that you have a default action on the switch statement that will show some sort of 404 page that indicates that the name in the URL was invalid. You ALWAYS want to have this anytime you're taking user input from the URL because people monkey with URLs all the time (and more innocently, copy+paste them wrong/incompletely all the time)
What component(s) do I need to implement and how can I hook it into the framework in order to have urls where the query parameters with names containing 2 or more words separated by hyphens?
For example:
I would have this url:
www.mysite.com/resource/i-am-looking-for?parameterOne=foo¶meterTwo=bar
I would like to have it like this:
www.mysite.com/resource/i-am-looking-for?parameter-one=foo¶meter-two=bar
My action would be something like this:
ActionResult DoSomething(string parameterOne, string parameterTwo)
The reason: user friendly urls and consistency
I need to have:
the component to integrate seamlessly with the framework URL helpers (Url.Action, Url.RouteUrl etc)
the incoming data to be bound to the action parameters (or model)
Is there a diagram where I can see the framework extensibility point in this regard?
Thank you!
public ActionResult SomeAction( string Some-Var ) {} is invalid because in C# variable names can not contain hyphens. Underscores ARE allowed, however so this IS valid public ActionResult SomeAction( string Some_Var ) {}
Now, if you relax your need to bind to strongly typed input vars to the action, you can accomplish your goal with Request.QueryString["some-var"] but you will have to handle the type conversion and error handling associated with it.
You can add Custom Value Provider Factory as shown below,
public class MyQueryStringValueProvider : NameValuePairsValueProvider
{
public QueryStringValueProvider(
HttpActionContext actionContext,
CultureInfo culture)
: base(
() =>{
var request = actionContext.ControllerContext;
foreach(var pair in request
.GetQueryNameValuePairs()){
yield return new KeyValuePair<String,String)(
Transform(pair.Key), pair.Value
);
}, culture)
{
}
private String Transform(String key){
// just removing all - , as it is case insensitive
//
return key.Replace("-","");
}
}
And you have to register your provider as shown below,
ValueProviderFactories.Factories.Add(
new MyQueryStringValueProvider());
For safe side, you can remove existing QueryStringValueProvider to avoid name conflicts for keys that does not have dash.
For dashes in Action Name, you can refer https://github.com/AtaS/lowercase-dashed-route
How about url encoding on client's side?
This way you can call controllers using general way. Please have a look one of the answers regarding that: Encode URL in JavaScript?
for example: this is your action.
public ActionResult GetNew(int id)
{
return View(news.Where(i => i.Id == id).SingleOrDefault());
}
First Step
Open App_Start>RouteConfig.cs open in your project.
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "GetNew",
url: "news/new-detail/{id}",
defaults: new { controller = "News", action = "GetNew", id = ""}
);
}
}
Now run your project and write your browser http://localhost:….(different for you)/news/new-detail/1
New ID No. 1 will open.
I hope it's been helpful
I would like to create a simple route which will allow me to have ONLY one item listed after the base URL (other than when it's a controller), and for that item to be passed into a controller as a parameter. for example:
www.mydomain.com/user1
www.mydomain.com/user2
www.mydomain.com/user3
www.mydomain.com/user3
where user1, user2 etc are usernames and are being passed dynamically, ie i don't want to have to create a controller for each username.
naturally i would want to make sure if something like this is possible that it wont cause conflicts with other genuine controller names, thus i guess the other controllers would have to have rules created specifically for them and listed above the wildcard route
i'm not sure how to do this as i guess the first item after the slash is usually a controller.
any ideas how to tackle this?
the examples i provided may seem ambiguous, when i put www.mydomain.com/user1 etc it represents that it could be anything (ie a username),for example, www.mydomain.com/jsmith, www.mydomain.com/djohnson, www.mydomain.com/sblake, www.mydomain.com/fheeley
the idea is that a users profile can be looked up simply by entering the domain name then a fwd slash and the username.
ASP.Net MVC routes are process from the top down, and as soon as a match is found it won't look any further for a match. So put your most specific routes first, and your wildcard route last. If none of the specific routes match, control will be passed to the wildcard route.
Use a route definition such as
routes.MapRoute("{username}", new { controller = "User", action = "View"});
in your global.asax.cs file but put it last in your list of route definitions.
MVC processes your route mappings from top to bottom, so put your most general route mappings at the top, and your more specific ones at the bottom.
After you do this you will need the corresponding controller/action so create a new Controller named "UsersController" with an action named "View", like as follows:
using System.Web.Mvc;
namespace Routes.Controllers
{
public class UsersController : Controller
{
//
// GET: /{username}
public ActionResult List(string username)
{
// Get User from database/repository and pass to view
var user = ...;
return View(user);
}
}
}
You have to do following thing.
Create one controller or Action for Handle above scenario. For example controller="Home" and Action="GetUser"
public ActionResult GetUser(string username){
// do your work
}
In Global.asax ( Top route)
// Look at point 3 for UserNameConstraint
route.MapRoute("UserRoute" , "{username}" , new { controller="Home" , action="GetUser" } , new { username = new UserNameConstraint() });
// Put your default route after above here
Now for Create Route constraint.
Hope this help you.
public class UserNameConstraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
List<string> userName = GetUserName from DB
userName.Contain(values[parameterName].ToString());
}
}
Create a route like as follows,
routes.MapRoute(
"DefaultWithUser", // Route name
"{user}/{controller}/{action}/{id}", // URL with parameters
new { user=UrlParameter.Optional, controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I've been searching for something similar but no luck. I want to build an app that uses different controllers for same urls. Basic idea is like that if a user is logged in as admin he uses lets say admin controller, if user is just a user he uses user controller. This is just an example, basically I want to have a function that decides what controller route takes.
Thank u everyone. Any help is greatly appreciated.
PS
Use of this:
Admin has different UI and options,
Output catching,
Separation of concern
You need to create a RouteConstraint to check the user's role, as follows:
using System;
using System.Web;
using System.Web.Routing;
namespace Examples.Extensions
{
public class MustBeAdmin : IRouteConstraint
{
public MustBeAdmin()
{ }
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
// return true if user is in Admin role
return httpContext.User.IsInRole("Admin");
}
}
}
Then, before your default route, declare a route for the Admin role, as follows:
routes.MapRoute(
"Admins", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Admin", action = "Index", id = UrlParameter.Optional }, // Parameter default
new { controller = new MustBeAdmin() } // our constraint
);
