Anonymous modules have no name to be referenced by

Hello! This is my first time with RoR and web development :stuck_out_tongue:

I’m trying to run the “hello world” script from the book Agile Wev
Development with Rails…

I’ve created my “SayController”:

class SayController < ApplicationController
def hello
end
end

and I’ve created my hello.rhtml with basic html that shows “Hello from
Rails!”.

However, when I try to access it, I get this error from the Webrick
console:
(I’m trying to go to http://localhost:3000/say/hello)

  • -> /say/hello

I don’t know why it doesn’t work, any idea? Thanks :wink:

Did you create the controller with script/generate?

yes, exactly like says the book

No one knows why I get an 404error when try to see the controller? I
need some help with that :S
