• Routing Skype call to another Voip company

  - by Anarchist

  Hello, As my project to do over this summer I would like to create a program that answers a Skype call using the Skype API and allows a user to connect to another VOIP provider (through SIP) and make calls by dialling through the client callers Skype application. I understand that the Skype API allows me to answer and receive keypad input, but I'm stuck on actually sending the sound of the call to a SIP client. Is there an API/library that would allow me to take the Skype receiving audio as input in the SIP client? Is this even possible? I'm not tied to a language but I had planned on using Python. Thanks.

• GAE app.yaml appears to be inconsistently routing requests

  - by kamens

  I have the following in app.yaml: - url: /gae_mini_profiler/static static_dir: gae_mini_profiler/static - url: /gae_mini_profiler/.* script: gae_mini_profiler/main.py - url: .* script: main.py and the following in gae_mini_profiler/main.py: def main(): logging.critical("gae_mini_profiler request!") run_wsgi_app(application) However, when I fire requests to, say, /gae_mini_profiler/request?request=ABC, and repeatedly reload the page, sometimes I will get the proper response (as well as a "gae_mini_profiler request!" log entry, and sometimes I get a blank response and nothing in the App Engine logs other than a 200 with an empty response body. This is completely reproducible, only happens in the live environment, and I'd say ~50% of the refreshes work while 50% do not. This only happens in production. Any ideas?

• Rails routing aliasing and namespaces

  - by kain

  Given a simple namespaced route map.namespace :api do |api| api.resources :genres end how can I reuse this block but with another namespace? Currently I'm achieving that by writing another routes hacked on the fly map.with_options :name_prefix => 'mobile_', :path_prefix => 'mobile' do |mobile| mobile.resources :genres, :controller => 'api/genres' end But it seems less than ideal.

• Determine if a url matches a Route, and pull out the terms if it does

  - by Kevin Montrose

  I've got a big old log file I'm trying to break down in terms of routes. Essentially, I'm getting input of a path (/questions/31415 for example) and a list of all the registered Routes. What I want out is a Route and the parameters specified in the route (so in, /questions/{id}/{answer} I'd get id and answers out). I've got a working solution that basically generates a nasty bit of regex on the fly with named groups to do matching and parsing all-in-one. My gut tells me this is a brittle way to do it, and frankly there has to be a better way, right?

• Passing parameters to custom RESTful routes in Rails (using :collection)

  - by dwhite

  I am trying to add a custom route to my RESTful routes using the :collection param on map.resources like so: map.resources :products, :collection => { :tagged => :get } The tagged action takes in a :tag parameter. I am able to link to the URL route using: tagged_products_path(:tag => tag.name). My issue with this is that the URL that this generates: /products/tagged?tag=electronic I would like the tag to be in the URL and not the tag, like so: /products/tagged/electronic Of course this can be accomplished by a separate named route, but I'm wondering if I'm missing something and there is a way to do this with the :collection hash. Thanks in advance for your help -Damien

• Synchronizing reading and writing with synchronous NamedPipes

  - by Mike Trader

  A Named Pipe Server is created with hPipe = CreateNamedPipe( zPipePath, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_WAIT | PIPE_READMODE_BYTE, PIPE_UNLIMITED_INSTANCES, 8192, 8192, NMPWAIT_USE_DEFAULT_WAIT, NULL) Then we immediately call: ConnectNamedPipe( hPipe, BYVAL %NULL ) Which blocks until the client connects. Then we proceed directly to ReadFile( hPipe, ... The problem is that it takes the Client takes a finite amount of time to prepare and write all the fcgi request parameters. This has usually not completed before the Pipe Server performs its ReadFile(). The Read file operation thus finds no data in the pipe and the process fails. Is there a mechanism to tell when a Write() has occurred/finished after a client has connected to a NamedPipe? If I had control of the Client process, I could use a common Mutex, but I don't, and I really do not want to get into I/O completion ports just to solve this problem! I can of course use a simple timer to wait 60m/s or so which is usually plenty of time for the wrote to complete, but that is a horrible hack.

• named_scope and substings

  - by Philb28

  I have a named_scope in rails that finds episodes by there directors given name named_scope :director_given, lambda { |dr| {:joins => :director, :conditions => ['given = ?', dr]} } It works great but I would like it to also work on substrings one the name. e.g. instead of having to search for 'Lucy' you could just search 'Lu'. P.S. I also have another named scope which does exactly the same thing but on the directors last name. It there a way to combine the two? Thanks,

• Deleting orphans with JPA

  - by homaxto

  I have a one-to-one relation where I use CascadeType.PERSIST. This has over time build up a huge amount of child records that has not been deleted, to such an extend that it is reflected in the performance. Now I wish to add some code that cleans up the database removing all the child records that are not referenced by a parent. At the moment we are talking 400K+ records, at I need to run the code on all customer installations just to be sure they do not run into the same problem. I think the best solution would be to run a named query (because we support two databases) that deletes the necessary records, and this is where I get into problems, because how should I write it in JPQL? The result I want can be defined like the following sql statement, which unfortunaltely does not run on MySQL. DELETE FROM child c1 WHERE c1.pk NOT IN (SELECT DISTINCT p.pk FROM child c2 JOIN parent p ON p.child = c2.pk);

• Java/C++ communication via pipe on Windows

  - by Warlax

  Hi, I have two separate programs, one in Java and one in C++, both running on Windows. We need to do bidirectional interprocess communication between the two. Up until now, we were using this awkward solution of writing to text files and reading them on the other side, where the producer would generate a .lock file when it's done writing and the consumer would remove that when it's done reading... like I said, awkward. If we were on *nix, we would use a pipe using popen() on the C++ and RadomAccessFile on the Java side. It seems to work well. What can we do on Windows? Can we use named pipes? Thank you.

• NetNamedPipe: varying response time when communication is idling

  - by Sven Künzler

  I have two WCF apps communicating one-way over named pipes. All is nice, except for one thing: Normally, the request/response cycle takes zero (marginal) time. However, if there was a time span of, say, half a minute without any communication, the request/response increases up to ~300-500ms. I looked around the net and I got the idea of using a heart beat/ping mechanism to keep the communication channel busy. Using trial and error I found that when doing a request each 10 seconds, the response times stay low. Starting at around 15s intervals, the "hiccup" response times begin to appear. Now I'm wondering where this phenomenon is originating from. I tried setting alle conceivable timeouts on both sides to 1 minute, but that did not help. Can anybody explain what's going on there?

• Best way to convert Stream (of unknown length) to byte array, in .NET?

  - by Frank Hamming

  Hello, I have the following code to read data from a Stream (in this case, from a named pipe) and into a byte array: // NPSS is an instance of NamedPipeServerStream int BytesRead; byte[] StreamBuffer = new byte[BUFFER_SIZE]; // defined elsewhere (less than total possible message size, though) MemoryStream MessageStream = new MemoryStream(); do { BytesRead = NPSS.Read(StreamBuffer, 0, StreamBuffer.Length); MessageStream.Write(StreamBuffer, 0, BytesRead); } while (!NPSS.IsMessageComplete); byte[] Message = MessageStream.ToArray(); // final data Could you please take a look and let me know if it can be done more efficiently or neatly? Seems a bit messy as it is, using a MemoryStream. Thanks!

• SQL 2008/2005 Hosting :: Error - “Named Pipes Provider, error: 40 – Could not open a connection to SQL Server”

  - by mbridge

  When setting up a Microsoft Windows Server 2008 system, I went through the motions to set up IIS, MS SQL Server 2008, and Visual Studio 2010 to use as a test-bed. One of the immediate benefits of setting up such a system is that most development can be done remotely: MS SQL Server Management Studio, Visual Studio’s Web development suite, as well as file shares, remote desktop, etc, make for a great way to remotely develop in ‘pristine’ conditions. But there are drawbacks, too, such as needing to deal with firewall issues, not being able to penetrate past a router or the requirement of setting up a VPN. One of the problems I encountered when trying to remote into the MS SQL Server 2008 that I’d set up was the following error: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server I followed the below steps, and was able to connect to the server after just a few moments of tinkering: 1. From the server in question, surf to this Microsoft article, and download and install the Firewall rules modification program. Never drop your firewall, even on a development machine, unless you have a really good reason to. 2. Launch SQL Server Configuration Manager. Navigate to SQL Server Network Configuration, then Protocols for your server name. Enable TCP/IP and Named Pipes by right-clicking and choosing Enable for each given Protocol Name. 3. Restart the SQL Server service from Services (or from command line, subsequently run “net stop mssqlserver” then “net start mssqlserver”. 4. Try your remote connection once more, and you should be able to connect. It’s not a terribly difficult concept, but one of the more challenging tasks developers face is dealing with environment setup. And while there is a certain blurred-line overlap between software development and server administration, sometimes the latter is daunting, especially given that you might set up only a handful of servers during your career.

• MVC Html.ActionLink not passing querystring properly

  - by Dave Hanna

  This seems like it should be pretty straight forward, but I'm apparently confused. I have a List view that displays a paged list. At the bottom I have a set of actionlinks: <%= Html.ActionLink("First Page", "List", new { page = 1} ) %> &nbsp; <%= Html.ActionLink("Prev Page", "List", new { page = Model.PageNumber - 1 }) %> &nbsp; <%= Html.ActionLink("Next Page", "List", new { page = Model.PageNumber + 1 }) %> &nbsp; <%= Html.ActionLink("Last Page", "List", new { page = Model.LastPage } )%> I'm using the basic default routes setup, except with "List" substituted for "Index": routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "List", id = UrlParameter.Optional } // Parameter defaults ); The problem is that the ActionLink helpers are generating links of the form: http://localhost:2083/Retrofit?page=2 rather than http://localhost:2083/Retrofit/?page=2 (with the trailing slash after the controller name & before the query string). When the first URL is routed, it completely loses the query string - if I look at Request.QueryString by the time it gets to the controller, it's null. If I enter the second URL (with the trailing slash), it comes in properly (i.e., QueryString of "page=2"). So how can I either get the ActionLink helper to generate the right URL, or get the Routing to properly parse what ActionLink is generating? Thanks.

• ASP.NET MVC 2 matches correct area route but generates URL to the first registered area instead.

  - by Sandor Drieënhuizen

  I'm working on a S#arpArchitecture 1.5 project, which uses ASP.NET MVC 2. I've been trying to get areas to work properly but I ran into a problem: The ASP.NET MVC 2 routing engine matches the correct route to my area but then it generates an URL that belongs to the first registered area instead. Here's my request URL: /Framework/Authentication/LogOn?ReturnUrl=%2fDefault.aspx I'm using the Route Tester from Phil Haack and it shows: Matched Route: Framework/{controller}/{action}/{id} Generated URL: /Data/Authentication/LogOn?ReturnUrl=%2FDefault.aspx using the route "Data/{controller}/{action}/{id}" That's clearly wrong, the URL should point to the Framework area, not the Data area. This is how I register my routes, nothing special there IMO. private static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); AreaRegistration.RegisterAllAreas(); routes.MapRoute( "default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional }); } The area registration classes all look like this. Again, nothing special. public class FrameworkAreaRegistration : AreaRegistration { public override string AreaName { get { return "Framework"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Framework_default", "Framework/{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = UrlParameter.Optional }); } }

• ASP.net MVC HttpException strange file not found

  - by Paddy

  I'm running asp.net MVC site on IIS6 - I've edited my routing to look like the following: routes.MapRoute( "Default", "{controller}.aspx/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); So all my urls now contain .aspx (as per one of the solutions from Phil Haack). Now, I catch all unhandled exceptions using Elmah, and for almost every page request, I get the following error caught by Elmah, that I never see on the front end (everything works perfectly): System.Web.HttpException: The file '/VirtualDirectoryName/Home.aspx' does not exist. System.Web.HttpException: The file '/VirtualDirectoryName/Home.aspx' does not exist. at System.Web.UI.Util.CheckVirtualFileExists(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVirtualPathObjectFactory(VirtualPath virtualPath, HttpContext context, Boolean allowCrossApp, Boolean noAssert) at System.Web.Compilation.BuildManager.CreateInstanceFromVirtualPath(VirtualPath virtualPath, Type requiredBaseType, HttpContext context, Boolean allowCrossApp, Boolean noAssert) at System.Web.UI.PageHandlerFactory.GetHandlerHelper(HttpContext context, String requestType, VirtualPath virtualPath, String physicalPath) at System.Web.UI.PageHandlerFactory.System.Web.IHttpHandlerFactory2.GetHandler(HttpContext context, String requestType, VirtualPath virtualPath, String physicalPath) at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig) at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) There is a Home controller, and it should be found, but I'm not sure a) where this is being called from, and b) why I don't see this error on the front end. Any ideas? Edited with answer: I think the answer for this can be found in this question: http://stackoverflow.com/questions/34194/asp-net-mvc-on-iis6

• How can I get controller type and action info from a url or from route data?

  - by Rob Levine

  How can I get the controller action (method) and controller type that will be called, given the System.Web.Routing.RouteData? My scenario is this - I want to be able to do perform certain actions (or not) in the OnActionExecuting method for an action. However, I will often want to know not the current action, but the "root" action being called; by this I mean I may have a view called "Login", which is my login page. This view may include another partial view "LeftNav". When OnActionExecuting is called for LeftNav, I want to be able to determine that it is really being called for the "root" aciton of Login. I realise that by calling RouteTable.Routes.GetRouteData(actionExecutingContext.HttpContext), I can get the route for the "root" request, but how to turn this into method and type info? The only solution I have so far, is something like: var routeData = RouteTable.Routes.GetRouteData(actionExecutingContext.HttpContext) var routeController = (string)routeData.Values["controller"]; var routeAction = (string)routeData.Values["action"]; The problem with this is that "routeController" is the controller name with the "Controller" suffix removed, and is not fully qualified; ie it is "Login", rather than "MyCode.Website.LoginController". I would far rather get an actual Type and MethodInfo if possible, or at least a fully qualified type name. Any thoughts, or alternative approaches? [EDIT - this is ASP.Net MVC 1.0]

• Help with route rewrite in asp.net mvc

  - by NachoF

  Im having a really hard time understanding routing. Please help me with this problem. Each of my controllers have these three actions right now Users have Index, Create and Edit Locations have Index, Create and Edit Companies have Index, Create and Edit The thing is, it all gets done through ajax. I have jquery ui tabs with two tabs for each, Create and Edit So the Index method is always the one that gets called for action links. and inside this main view is that you can call(by clicking on the tab icon) the other methods that return an ajax view that gets output into the jqeury tab (I hope thats clear) I have a sidebar with links to the controllers. and to specific methods of these controllers. The wanted behavior is that it should actually go into the Index Method and then with some logic autoload the wanted tab. It all works just fine right now. But my urls are horrible. To get to the create method for Users I have to go this url http://localhost/Users/Index/1 http://localhost/Users/Index/2 I want the behavior of these links to be remapped to these links http://localhost/Users/Create http://localhost/Users/Edit So even though it seems as if you are calling the Create method of the controller you are actualling always calling the Index Method.... (I know how to transform Create into "1" and Edit into two, so dont worry about that part Hope thats clear. Thanks in advance Edit: Just realized that this might not be possible cause then when I actually need to call the methods (with ajax) it wont know what to do.... am I correct?

• has_many, belongs_to and comment forms

  - by Koning Baard XIV

  I'm having two models: Snippet and SnippetComment. These also have their own controllers, as well as views. In /app/views/snippets/show.html.erb I have a form that starts like this: <% form_for(@new_snippet_comment) do |form| %> SnippetComment belongs to one Snippet, and a Snippet belongs to one User. This means that I have this routing: map.resources :users do |user| user.resources :snippets do |snippet| snippet.resources :snippet_comments, :as => "comments" end end So when I submit the SnippetComment form in the SnippetController#show view, this request should be made: POST /users/x/snippets/x/comments HTTP/1.1 (where x is the User's or Snippet's id). The problem is that I don't even get the comment submission form, but rahter this: NoMethodError in Snippets#show Showing app/views/snippets/show.html.erb where line #29 raised: undefined method `snippet_comments_path' for Extracted source (around line #29): 26: <% if current_user %> 27: <h2>Schrijf een nieuwe reactie</h2> 28: 29: <% form_for(@new_snippet_comment) do |form| %> 30: 31: <p> 32: <%= form.text_area :body %> RAILS_ROOT: /Users/jeffatwood/Dev/youjustdontneedmyrealname Application Trace | Framework Trace | Full Trace /Users/jeffatwood/.gem/ruby/1.8/gems/actionpack-2.3.5/lib/action_controller/polymorphic_routes.rb:107:in `__send__' /Users/jeffatwood/.gem/ruby/1.8/gems/actionpack-2.3.5/lib/action_controller/polymorphic_routes.rb:107:in `polymorphic_url' /Users/jeffatwood/.gem/ruby/1.8/gems/actionpack-2.3.5/lib/action_controller/polymorphic_routes.rb:114:in `polymorphic_path' /Users/jeffatwood/.gem/ruby/1.8/gems/actionpack-2.3.5/lib/action_view/helpers/form_helper.rb:298:in `apply_form_for_options!' /Users/jeffatwood/.gem/ruby/1.8/gems/actionpack-2.3.5/lib/action_view/helpers/form_helper.rb:277:in `form_for' /Users/jeffatwood/Dev/youjustdontneedmyrealname/app/views/snippets/show.html.erb:29:in `_run_erb_app47views47snippets47show46html46erb' /Users/jeffatwood/Dev/youjustdontneedmyrealname/app/controllers/snippets_controller.rb:19:in `show' Request Parameters: {"id"=>"1", "user_id"=>"2"} Show session dump Response Headers: {"Content-Type"=>"text/html", "Cache-Control"=>"no-cache"} Can anyone help me with this problem?

• Optional route parameters in ASP.NET 4 RTM no longer work as before

  - by Simon_Weaver

  I upgraded my project to ASP.NET 4 RTM with ASP.NET MVC 2.0 RTM today. I was previously using ASP.NET 3.5 with ASP.NET MVC 2.0 RTM. Some of my routes don't work suddenly and I don't know why. I'm not sure if something changed between 3.5 and 4.0 - or if this was a regression type issue in the 4.0 RTM. (I never previously tested my app with 4.0). I like to use Url.RouteUrl("route-name", routeParams) to avoid ambiguity when generating URLs. Here's my route definition for a gallery page. I want imageID to be optional (you get a thumbnail page if you don't specify it). // gallery id routes.MapRoute( "gallery-route", "gallery/{galleryID}/{imageID}/{title}", new { controller = "Gallery", action = "Index", galleryID = (string) null, imageID = (string) null, title = (string) null} ); In .NET 3.5 / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => /gallery/cats Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles In .NET 4.0 RTM / ASP.NET 2.0 RTM / IIS7 Url.RouteUrl("gallery-route", "cats") => null Url.RouteUrl("gallery-route", "cats", 4) => /gallery/cats/4 Url.RouteUrl("gallery-route", "cats", 4, "tiddles") => /gallery/cats/4/tiddles Previously I could supply only the galleryID and everything else would be ignored in the generated URL. But now it's looking like I need to specify all the parameters up until title - or it gives up in determining the URL. Incoming URLs work fine for /gallery/cats and that is correctly mapped through this rule with imageID and title both being assigned null in my controller. I also tested the INCOMING routes with http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx and they all work fine.

• django powering multiple shops from one code base on a single domain

  - by imanc

  Hey, I am new to django and python and am trying to figure out how to modify an existing app to run multiple shops through a single domain. Django's sites middleware seems inappropriate in this particular case because it manages different domains, not sites run through the same domain, e.g. : domain.com/uk domain.com/us domain.com/es etc. Each site will need translated content - and minor template changes. The solution needs to be flexible enough to allow for easy modification of templates. The forms will also need to vary a bit, e.g minor variances in fields and validation for each country specific shop. I am thinking along the lines of the following as a solution and would love some feedback from experienced django-ers: In short: same codebase, but separate country specific urls files, separate templates and separate database Create a middleware class that does IP localisation, determines the country based on the URL and creates a database connection, e.g. /au/ will point to the au specific database and so on. in root urls.py have routes that point to a separate country specific routing file, e..g (r'^au/',include('urls_au')), (r'^es/',include('urls_es')), use a single template directory but in that directory have a localised directory structure, e.g. /base.html and /uk/base.html and write a custom template loader that looks for local templates first. (or have a separate directory for each shop and set the template directory path in middleware) use the django internationalisation to manage translation strings throughout slight variances in forms and models (e.g. ZA has an ID field, France has 'door code' and 'floor' etc.) I am unsure how to handle these variations but I suspect the tables will contain all fields but allowing nulls and the model will have all fields but allowing nulls. The forms will to be modified slightly for each shop. Anyway, I am keen to get feedback on the best way to go about achieving this multi site solution. It seems like it would work, but feels a bit "hackish" and I wonder if there's a more elegant way of getting this solution to work. Thanks, imanc

• Open PDF Content files in ASP.NET MVC 2

  - by mcbingo

  I want to provide simple href links to my PDF forms that reside in my Forms folder. I have a created a simple Index.aspx and FormController Index action that simple iterates through the list of PDF files using my FormMetaData.xml file. The links get created just fine but when you click on the links I get a 404 exception. That looks like this: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Forms/ccindteamgolfform.pdf Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927 This seems like this should open up a new browser window with the PDF in it but perhaps I am making a bad assumption. The PDF content files have Build Action of Content and Copy to Output set to Copy Always. Here is an example output html for the link from my Index.aspx page: <span class="form"> <a href="Forms/ccindteamgolfform.pdf" target="_blank"> <span class="description">Entry Form</span></span> I must be missing something because this does not work. Do I need to add a MapRoute for these documents? Or am I missing something else with the routing? This seems like it should not be that difficult.

• How do I set up routes to enable me to call different actions on the same controller?

  - by Remnant

  I am building my first asp.net mvc application for learning and development purposes and have come across an issue that I'd like some guidance with. Suppose I have a controller with two actions as follows: public class MyController : Controller { public ActionResult Index() { dbData = GetData("DefaultParameter") return View(dbData); } public ActionResult UpdateView(string dbParameter) { dbData = GetData("dbParameter"); return View(dbData); } } On my webpage I have the following: <% using (Html.BeginForm("UpdateView", "MyController")) %> <% { %> <div class="dropdown"><%=Html.DropDownList("Selection", Model.List, new { onchange="this.form.submit();" })%></div> <% } %> I have the following route in Global.asax: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute("Default", "{controller}", new { controller = "MyController", action = "Index"}); } The issue I am having is as follows: When I use the dropdownlist I get an error saying that /MyController/UpdateView could not be found. It therefore seems that I need to add an additional route as follows: routes.MapRoute("Default", "{controller}", new { controller = "MyController", action = "UpdateView"}); However, this causes two new issues for me: Due to the hierachy within the routing list, the similarity of the routes means that the one that appears first in the list is always executed. I don't see why I need to create another route for UpdateView. All I want to do is to retrieve new data from the database and update the view. I don't see what this has to do with the URL schema. It feels like I have gone down the wrong track here and I have missed something quite fundamental?

• Rails redirections with new users and logins

  - by Kenji Crosland

  So I'm trying to get the user to return to the page they were looking at before they click "log in" This is what I got in my user application controller: def redirect_back_or_default(default) redirect_to(session[:return_to] || default) session[:return_to] = nil end And this is what I have in my sessions controller: def new @user_session = UserSession.new session[:return_to] = request.referer end end def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default(home_path) else render :action => :new end end This works fine most of the time but if a user logs in right after they register to the site, they will get redirected to a blank page. I imagine this is the "create" action because it was the last action before going to user sessions new. So I tried this: def new @user_session = UserSession.new unless request.referer == join_path session[:return_to] = request.referer end end And this tries to take me back to the login page after I log in. What I'd really like to do is have the user see their profile when they log in for the very first time. This wouldn't give me a user id and raised a routing error def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Login successful!" redirect_back_or_default(user_path(current_user)) else render :action => :new end end Anybody gone through these redirecting acrobatics before? I can't seem to get it to work. I'm using authlogic if that helps.
