In my first approach with Rails I have simply create a void SayController and static hello.rhtml view but when the page http://localhost:3000/say/hello started return me a Routing Error like this:

No route matches [GET] "/say/hello"
Try running rake routes for more information on available routes.

Rails version: 3.2.6

Seems like you didn't add a route for hello to your config/routes.rb file.

YourApp::Application.routes.draw do
  match 'say/hello' => 'say#hello', :as => :hello
end

This will match route say/hello to controller say (the part before #) and action hello (the part after #).

:as => :hello makes it a named route so you can refer to it as hello_path from within your app.

The error message tells you to run rake routes (from the console) which will show you the existing routes in your app.

You should have something in your config/routes.rb to define that route. Try: 

match 'say/hello' => 'say#hello', :as => 'say_hello'

The go to localhost:3000/say/hello Also check out this documentation:

  • it work, fine! but I don't understand if it's a task to run every time I create a controller? – mariobros Jun 19 '12 at 12:47
  • If you create a new method in controller and want to route to it, you have to define that in the config/routes.rb. – u19964 Jun 19 '12 at 12:53
  • Now i have Template Missing error: Missing template say/hello, application/hello with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}. Searched in: * "C:/rails_proj/demo/app/views" – mariobros Jun 19 '12 at 13:07
  • This is how Model View Controller in Rails works. You have a controller Say with an action Hello, now you need a View Hello that is inside Say. The app looks into app/views/application/ or app/views/say/ for something like hello.html.erb to display on the web. Try creating such html file. – u19964 Jun 19 '12 at 13:12

I assume, controller: say and action: hello

Add following to config/route.rb

 get 'say/hello' => 'Say#hello'
