My routes.rb reads at the top:
Hello::Application.routes.draw do match ':controller(/:action(/:id(.:format)))'
and then all the commented material it comes with and an "end" at the end of the file.
But when I type http://localhost:3000 into my browser I get the following error message:
Routing Error No route matches "/"
I'm stumped.

I don't see that you've routed anything to the '/' path.
Your route requires the controller to be in the path.
First step would be to uncomment this # You can have the root of your site routed with "root" # just remember to delete public/index.html. # root :to => "welcome#index"
replacing 'welcome' with the controller you want / to route to and index.html with the action.
Along those lines, usually there is a public/index.html that should be displayed.
Do you have a file in public/html?

The above means that rails can only recognized paths that start with the name of a controller, optionally followed by an action and id. '/' clearly doesn't fall into that pattern so you get a routing error. One way of specifying a default root is by saying
root :to => 'pages#main'
which says that / should be routed to the main action in PagesController

I'm following the instructions in Beginning Rails 3:
$ rails generate controller salutation Then I added a Hello method to the controller. Then I created a hello.html.erb template in app/views/salutation.
So the routes.rb file with this code:
Hello::Application.routes.draw do match ':controller(/:action(/:id(.:format)))' end
is supposed to deliver the desired result of "Hello World!".
But I went ahead and changed the routes.rb file to read:
Hello::Application.routes.draw do root :to => "salutation#hello"
That delivers the Hello World! in the browser, but along with the .erb code:
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss \fcharset0 Arial;}} {\*\generator Msftedit 5.41.21.2509;}\viewkind4\uc1\pard\f0\fs20 \par \tab \par \tab\tab Hello World! \par \tab \par \par }
What to do?

That looks like you edited your template with an editor that saved it as an rtf file rather than plain text.

You're right! Much thanks to all of the above responders.
But for the sake of learning, can anyone tell me why the Beginning Rails 3 code doesn't work, and what exactly is it supposed to do?
