No route matches [GET] "/say/hello" - ruby-on-rails

Question

I've written a very small program to help me learn ruby. Below is the error I get from the server logs.
This is the URL I am trying from browser and followed errors: localhost:3000/say/hello
Started GET "/say/hello" for 127.0.0.1 at Sun Jun 10 14:28:45 +0800 2012

I've had a look at a few other SO threads, but none seem to relate specifically to my problem.

Answer 1

In your routes.rb you need either:
match "say/hello" => "myController#myaction" (replacing controller and action with proper values)
or
match ':controller(/:action(/:id))(.:format)' Which will allow you to use code like: link_to "hello", :controller => "mycontroller", :action => "myaction" or enter the URL (like /say/hello)
The former is the preferred method because users cannot go to urls you don't want them to.
Also, your view should be in a subdirectory with the name of the controller that will be using it, not in the actual 'views' directory
EDIT:
Looking at answer below you need to make your file an html.erb not rhtml

Answer 2

Type bundle execute rake routes to list all the routing paths in your application. Check if :controller=>"say", :action=>"hello" there.
Also this doesn't follow the restful rules of rails, so you maybe need to uncomment the match ':controller(/:action(/:id))(.:format)', which at the last line of config/routes.rb.
