I installed Instant Rails on windows and tested using http://127.0.0.0:3000 on browser it showing WELCOME page.
Next : i started a sample application using commands
> rails hello
> ruby script/generate controller Hello index
with this it created a hello app
but i am when accessing http://127.0.0.0:3000/hello
it is giving me
Routing Error
No route matches “/hello” with {:method=>:get}
You should have a view called hello.html.erb in the views/Hello folder
