IronRubyMvc - an extension to ASP.NET MVC to support IronRuby

Getting started

  1. Install ASP.NET MVC (link?)
  2. Create a new ASP.NET MVC project in Visual Studio
  3. Add a reference to System.Web.Mvc.IronRuby.dll
  4. Open Global.asax.cs and ...

    // add this to your usings using System.Web.Mvc;

    // make the subclass of "MvcApplication" be "RubyMvcApplication" namespace MyIronRubyMvcApp { public class MvcApplication : RubyMvcApplication {



  5. Create Routes.rb and define a default route:

    $routes.ignore_route "{resource}.axd/{*pathInfo}" $routes.map_route "default", "{controller}/{action}/{id}", :controller => 'Home', :action => 'index', :id => ''


Ruby Controllers live in the same directory as normal MVC controllers: the "Controllers" directory.

# Controllers\HomeController.rb class HomeController < Controller def index "Hello, World" end end

Run the application from Visual Studio, and it will display "Hello, World"


You can create filters in a number of ways.

class YourController < Controller

 # before_action, after_action, around_action, before_result, after_result, authorized_action, exception_action all work
 before_action :index do |context|
   # do some filtering stuff here

 around_result :index do |context|
   # do some result filtering stuff here

 before_action :index, :method_filter

 authorized_action :some_other_action do |context|
   # do some authorization checking work here

 filter :index, YourFilter
 filter :some_other_action, DifferentYourFilter

 # executes for each action
 filter YourControllerFilter 

 def index
   # index action

 def some_other_action
   # index action

 def method_filter
  # do some filter stuff here


You can define the following types of filters: ActionFilter, ResultFilter, AuthorizationFilter, ExceptionFilter

class YourFilter < ActionFilter

def on_action_executing(context)
  # Do some filter work here

def on_action_executed(context)
  # Do some filter work here



Ruby views exist in the Views directory, in a sub-folder with the same name as the Controller the View is intended to be used in. To use ERb views, the file should have the ".html.erb" extension. Shared views, such as layouts, are in the "Views/Shared" directory.

For example, an "index" view for the HomeController would be in Views/Home/index.html.erb.

# Controllers/HomeController class HomeController < Controller def index data = "Hello, World" view 'index', 'layout', data end end

MVC says: <%= model %>

<% yield %>


IronRubyMvc.Test - Tests Library. IronRubyMvcWeb - "Hello, World" test website. You need to change the connection string and attach the database or use sql express. Pictures - "Real" Demo application

Running IronRubyMvcWeb: 1. Start cassini against the website

Running Pictures: 1. Start cassini against Pictures 2. ruby Pictures\server\app.rb
