Redirect with ASP.NET MVC MapRoute - asp.net-mvc

On my site, I have moved some images from one folder to another.
Now, when I receive a request for old images '/old_folder/images/*' I want to make a permanent redirect to new folder with these images '/new_folder/images/*'
For example:
/old_folder/images/image1.png => /new_folder/images/image1.png
/old_folder/images/image2.jpg => /new_folder/images/image2.jpg
I have added a simple redirect controller
public class RedirectController : Controller
{
public ActionResult Index(string path)
{
return RedirectPermanent(path);
}
}
Now I need to setup proper routing, but I don't know how to pass the path part to the path parameter.
routes.MapRoute("ImagesFix", "/old_folder/images/{*pathInfo}", new { controller = "Redirect", action = "Index", path="/upload/images/????" });
Thanks

I would do in next way
routes.MapRoute("ImagesFix", "/old_folder/images/{path}", new { controller = "Redirect", action = "Index" });
and in controller like that
public class RedirectController : Controller
{
public ActionResult Index(string path)
{
return RedirectPermanent("/upload/images/" + path);
}
}

first download and install RouteMagic package from this link , then redirect your old address to the new address Like the below code :
var NewPath = routes.MapRoute("new", "new_folder/images/{controller}/{action}");
var OldPath = routes.MapRoute("new", "old_folder/images/{controller}/{action}");
routes.Redirect(OldPath ).To(NewPath );

Redirecting Routes To Maintain Persistent URLs

Answer above using RouteMagic is a good idea, but the example code is wrong (it's included in Phil's post as a bad example).
From the RouteMagic Github demo site global.asax.cs:
// Redirect From Old Route to New route
var targetRoute = routes.Map("target", "yo/{id}/{action}", new { controller = "Home" });
routes.Redirect(r => r.MapRoute("legacy", "foo/{id}/baz/{action}")).To(targetRoute, new { id = "123", action = "index" });
If you specify two routes, you will be setting up an extra mapping that will catch URLs which you don't want.

How to utilize a user-defined url action in asp,net mvc?

My hope is to provide a method to end users that will let them enter a value 'SmallBuildingCompany', and then use this value to make a custom url that will redirect to an informational view. so for example, www.app.com/SmallBuildingCompany. Can anyone point me to some information to help on this?

My attempt so far:
I added this within RouteConfig.
RouteTable.Routes.MapRoute(
"Organization",
"O/{uniqueCompanyName}",
new { controller = "Organization", action = "Info" }
and added a new controller method and view under the organization controller.
public async Task<ActionResult> Info(string uniqueCompanyName)
{
var Org = db.Organizations.Where(u => u.uniqueCompanyName == uniqueCompanyName).FirstOrDefault();
Organization organization = await db.Organizations.FindAsync(Org.OrgId);
return View("Info");
}
You can achieve this by using the SmallBuildingCompany part of the URL as a parameter for an action that is used to display every informational view.
Set up the Route in Global.asax.cs to extract the company name as parameter and pass it to the Index action of CompanyInfoController:
protected void Application_Start() {
// Sample URL: /SmallBuildingCompany
RouteTable.Routes.MapRoute(
"CompanyInfo",
"{uniqueCompanyName}",
new { controller = "CompanyInfo", action = "Index" }
);
}
Note that this Route will probably break the default route ({controller}/{action}/{id}), so maybe you want to prefix your "Info" route:
protected void Application_Start() {
// Sample URL: Info/SmallBuildingCompany
RouteTable.Routes.MapRoute(
"CompanyInfo",
"Info/{uniqueCompanyName}",
new { controller = "CompanyInfo", action = "Index" }
);
}
Then the CompanyInfoController Index action can use the uniqueCompanyName parameter to retrieve the infos from the database.
public ActionResult Index(string uniqueCompanyName) {
var company = dbContext.Companies.Single(c => c.UniqueName == uniqueCompanyName);
var infoViewModel = new CompanyInfoViewModel {
UniqueName = company.UniqueName
}
return View("Index", infoViewModel);
}
ASP.NET Routing

ASP.NET MVC Areas in Individual Projects - Refactor AreaRegistration Stuff

I'm trying to molularize my ASP.NET MVC application by moving each Area into their own project. Everything was working fine until i decided to refactor out the AreaRegistration stuff and use my own approach (This way i can also register filters and dependencies within my module). Using reflector i have managed to come up with the following.
First i implement the following interface for each module/area:
public interface IModule {
string ModuleName { get; }
void Initialize(RouteCollection routes);
}
E.g.:
public class BlogsModule : IModule {
public string ModuleName { get { return "Blogs"; } }
public void Initialize(RouteCollection routes) {
routes.MapRoute(
"Blogs_Default",
"Blogs/{controller}/{action}/{id}",
new { area = ModuleName, controller = "Home", action = "Index",
id = UrlParameter.Optional },
new string[] { "Modules.Blogs.Controllers" }
);
}
}
Then in my Global.asax file (Application_Start event) i say:
// Loop over the modules
foreach (var file in Directory.GetFiles(Server.MapPath("~/bin"), "Modules.*.dll")) {
foreach (var type in Assembly.LoadFrom(file).GetExportedTypes()) {
if (typeof(IModule).IsAssignableFrom(type)) {
var module = (IModule)Activator.CreateInstance(type);
module.Initialize(RouteTable.Routes);
}
}
}
I then removed the existing AreaRegistration stuff. Everything is working fine up to this point. When i run my application and render the link to a module, e.g.:
#Html.ActionLink("Blogs", "Index", "Home", new { area = "Blogs" }, null)
The correct url is displayed but when i click on the url it displays the wrong view. After debugging it looks like the url is routed to the correct Action within the HomeController of my Blogs module. However it tries to display the Home/Index.cshtml view in the main project and not the one in the module/area. I'm guessing somewhere along the lines i have missed how to tell the view engine to treat the routed url as an area as it seems to be ignoring the AreaViewLocationFormats (inside the RazorViewEngine).
I'd appreciate it if someone could show me what i'm missing. Thanks
After further refactoring it appears that, the view engine looks for an area data token. I therefore changed the code to add routes in Initialize method of the module as:
// Create the route
var route = new Route("Blogs/{controller}/{action}/{id}", new RouteValueDictionary(new { area = ModuleName, controller = "Home", action = "Index", id = UrlParameter.Optional }), new MvcRouteHandler());
// Add the data tokens
route.DataTokens = new RouteValueDictionary();
route.DataTokens["area"] = this.ModuleName;
route.DataTokens["UseNamespaceFallback"] = false;
route.DataTokens["Namespaces"] = new string[] { "Modules.Blogs.Controllers" };
// Add the route
routes.Add(route);
Hope this helps.

ASPMvc Routing Issues with legacy url

I have got a legacy url that I cannot change, which is output on a page which needs to now post to a new MVC version of the page:
http://somesite.com/somepage?some-guid=xxxx-xxxx
Now I am trying to map this to a new controller but I need to get the some-guid into my controller:
public class MyController : Controller
{
[HttpGet]
public ActionResult DisplaySomething(Guid myGuid)
{
var someResult = DoSomethingWithAGuid(myGuid);
...
}
}
I can change the controller and routes as much as I like, however the legacy url cannot change. So I am a bit stumped as to how I can get access to the some-guid.
I have tried routing with the ?some-guid={myGuid} but the routing doesn't like the ?, so then I tried to let it autobind, but as it contains hyphens it doesn't seem to bind. I was wondering if there was any type of attribute I could use to hint that it should bind from a part of the querystring...
Any help would be great...
I would have thought you would have done a route a bit like this..
routes.MapRoute(
"RouteName", // Name the route
"somepage/{some-guid}", // the Url
new { controller = "MyController", action = "DisplaySomething", some-guid = UrlParameter.Optional }
);
The {some-guid} part of URL matches your url parmater and passes it to the controller.
So if you have your action like so :
public ActionResult DisplaySomething(Guid some-guid)
{
var someResult = DoSomethingWithAGuid(some-guid);
...
}
Give that a go and see how you get on..
routes.MapRoute(
"Somepage", // Route name
"simepage", // URL with parameters
new { controller = "MyController", action = "DisplaySomething"
);
And then in your controller:
public class MyController : Controller {
public ActionResult DisplaySomething(Guid myGuid)
{
var someResult = DoSomethingWithAGuid(myGuid);
...
}
}
Try this:
routes.MapRoute("SomePageRoute","Somepage",
new { controller = "MyController", action = "DisplaySomething" });
And then in your controller:
public ActionResult DisplaySomething() {
Guid sGuid = new Guid(Request.QueryString["some-guid"].ToString());
}

Pretty URL ASP.NET MVC

How can I get pretty urls like localhost:8888/News/Example-post instead of localhost:8888/Home/Details/2
My HomeController has the following for the Details method
public ActionResult Details(int id)
{
var ArticleToView = (from m in _db.ArticleSet where m.storyId == id select m).First();
return View(ArticleToView);
As the ASP.NET routing system is somewhat complicated, there are many ways to accomplish what you describe.
First of all, do you just want to have a pretty URL for the Details method? If so, you might consider renaming HomeController to NewsController or moving the Details method into a new NewsController class - that will automatically form the /News part of the URL. If you don't want a /Details part, you might rename your Details method Index, as that will be automatically called by /News. Finally, you need to change your int id parameter into string name.
If you want many custom URLs, you're going to have to define your own routes. Here are two ways of doing this:
1.
The easiest way I've found is to use an ASP.NET MVC Attribute-Based Route Mapper. That way, all you have to do is add an attribute on each method you want a pretty URL for and specify what URL you want.
First, you must follow a few steps to set up the attribute-based route mapping system, as outlined on that link.
After completing those steps, you must change your method to look like this:
[Url("News/{name}")]
public ActionResult Details(string name)
{
var ArticleToView = (from m in _db.ArticleSet where m.storyName == name select m).First();
return View(ArticleToView);
}
2.
Alternatively, you can define your custom routes manually in Global.asax.cs. In your RegisterRoutes method, you can add the following in the middle:
routes.MapRoute(
"NewsDetails",
"News/{name}",
new { controller = "News", action = "Details", name = "" }
);
What I do on my sites is that I check the URL against either the Page Title or Page Stub in cases where the page titles could have the same name for instance if you have a site that posts a "Picture of the Week" you may want to use a stub instead of title as you'll have multiples named the same thing.
URLs look like this: http://mySite.com/Page/Verse-of-the-Week
Global.asax contains this:
routes.MapRoute("Pages", "{controller}/{pageID}", new { controller = "Page", action = "Index", pageID = "Home" });
PageController is this:
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(string pageID)
{
if (pageID == null)
{
pageID = pageRepository.HomeOrLowest();
}
var p = pageRepository.ByStub(pageID);
if (p == null) { return RedirectToAction("NotFound", "Error"); }
return View(p);
}
The repository looks like this:
private static Func<mvCmsContext, string, Page> _byStub =
CompiledQuery.Compile((mvCmsContext context, string pageTitle) =>
(from p in context.Pages
where p.pageTitle.Replace(" ", "-") == pageTitle
select p).SingleOrDefault());
public Page ByStub(string pageTitle)
{
return _byStub(context, pageTitle);
}
I hope that helps.
Edit to add duplicate handling:
private static Func<mvCmsContext, string, int> _pageExists =
CompiledQuery.Compile((mvCmsContext context, string pageTitle) =>
(from p in context.Pages
where p.pageTitle.Replace(" ", "-") == pageTitle
select p).Count());
public bool PageExists(string pageTitle)
{
return Convert.ToBoolean(_pageExists(context, pageTitle));
}
Validates like this:
IValidationErrors errors = new ValidationErrors();
if (CreateOrEdit == "Create")
{
if (pageRepository.PageExists(model.pageTitle) && !String.IsNullOrEmpty(model.pageTitle))
errors.Add("pageTitle", "A page with this title already exists. Please edit it and try again.");
}

ASP.net MVC Areas and creating an ActionLink with ID (SEO / clean URL)

I am building a Help Desk Ticket system for a client using ASP.NET MVC 1.0 / C#. I have implemented Steven Sanderson's "App Areas in ASP.NET MVC, Take 2" and it is working great.
In my Globabl.asax page I have some routes defined as such:
public static void RegisterRoutes(RouteCollection routes)
{
// Routing config for the HelpDesk area
routes.CreateArea("HelpDesk", "ProjectName.Areas.HelpDesk.Controllers",
routes.MapRoute(null, "HelpDesk/{controller}/{action}", new { controller = "Ticket", action = "Index" }),
routes.MapRoute(null, "HelpDesk/Ticket/Details/{TicketId}", new { controller = "Ticket", action = "Details", TicketId = "TicketId" })
);
}
So, if I enter "http://localhost/HelpDesk/Ticket/Details/12" in the browser address bar manually, I get the results I expect. Here is my controller:
public ActionResult Details(int TicketId)
{
hd_Ticket ticket = ticketRepository.GetTicket(TicketId);
if (ticket == null)
return View("NotFound");
else
return View(ticket);
}
In my view I have:
<%= Html.ActionLink(item.Subject, "Details", new { item.TicketId } )%>
But that code generates "http://localhost/HelpDesk/Ticket/Details?TicketId=12" which also returns the expected results. My Question is...
How do I define an ActionLink when using Steven Sanderson's Areas that will create a clean URL like: "http://localhost/HelpDesk/Ticket/Details/12" ?
Try
<%= Html.ActionLink(item.Subject, "Details", new { TicketId = item.TicketId } )%>
The ActionLink method expects a dictionary with keys that match the parameter names. (Note that passing an anonymous object is a convenience for this). Anything else I believe it will just tag onto the end of the URL.
EDIT: The reason that this isn't working for you is because your first route matches and takes precedence (controller and action), but defines no TicketId parameter. You need to switch the order of your routes. You should always put your most specific routes first.
Try
<%= Html.ActionLink(item.Subject, "Details", new { TicketId=item.TicketId } )%>
I think Womp has it ...
Oh and while you are swapping your routes try
routes.MapRoute(null, "HelpDesk/Ticket/Details/{TicketId}", new { controller = "Ticket", action = "Details"})
I think the , TicketId = "id" is messing things up
Hope that helps,
Dan
