routing

In rails 2.3.5 you could do something like this inside the routes.rb file: map.root :controller => "pages", :action => "show", :id => 3 In rails 3 I haven't found any way to pass a specific parameter (like in rails 2.3.5 with :id => 3). I know I can handle it from the controller and have the same result (which I did), but I was wondering if there is a way to do the same thing in rails 3 from the routes.rb or has it changed because it is better practice for some reason? Are you sure the following doesn't work? root :to => "pages#show", :id => 3 来源： https://stackoverflow.com/questions/3533960

I'm using Express JS and I want a functionality similar to Django's reverse function. So if I have a route, for example app.get('/users/:id/:name', function(req, res) { /* some code */ } ) I'd like to use a function for example reverse('/users/:id/:name', 15, 'John'); or even better reverse('/users/:id/:name', { id : 15, name : 'John' }); which will give me the url /users/15/John . Does such function exist? And if not then do you have any ideas how to write such function (considering Express' routing algorithm)? Here is your code: function reverse(url, obj) { return url.replace(/(\/:\w+\??)/g,

Let's say I have an action that optionally accepts two parameters: def foo(name: String, age: Integer) = Action { // name & age can both be null if not passed } How do I setup my route file to work with any of the following call syntaxes: /foo /foo?name=john /foo?age=18 /foo?name=john&age=18 /foo?authCode=bar&name=john&age=18 // The controller may have other implicit parameters What is the correct syntax for this? Something like this should work: GET /foo controllers.MyController.foo(name: String ?= "", age: Int ?= 0) Since your parameters can be left off you need to provide default values for

So I have a route like this in my MVC 3 application running under IIS 7: routes.MapRoute( "VirtualTourConfig", "virtualtour/config.xml", new { controller = "VirtualTour", action = "Config" } ); The trick is that a file actually exists at /virtualtour/config.xml. It seems like the request is just returning the xml file at that location instead of hitting the route, which processes the XML, makes some changes and returns a custom XmlResult. Any suggestions on how I can tell my application to hit the route and not the actual file in the event that the file exists on disk? EDIT: It appears that I

I am working on a website in asp.net mvc. I have a route routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); which is the default route. And I have a method public ActionResult ErrorPage(int errorno) { return View(); } Now if I want to run this code with http://something/mycontroller/Errorpage/1 it doesn't work. But if I change the parameter name to id from errorno it works. Is it compulsory to have same parameter name for this method? Or do I need to

Maybe I am missing something but there doesn't seem to be a way to define querystring parameters in routes in Symfony2 so that they can be passed into a controller. For instance, instead of generating a URI like /blog/my-blog-post (from Symfony2's routing documentation ) and passing it to the following route: # app/config/routing.yml blog_show: pattern: /blog/{slug} defaults: { _controller: AcmeBlogBundle:Blog:show } I would prefer to generate a URI like /blog?slug=my-blog-post . The problem is I can't find anywhere to define the slug parameter in the route configuration file (like its {slug}
