Just starting out with RoR3, and have tried to render first page.

Here is code for hello\_controller.rb

class HelloController \< ApplicationController  
def world  
render :text =\> “

# Hello world!
”  
end  
end

Did not make any changes to the routes.rb file. When I went to  
[http://localhost:3000/hello/world](http://localhost:3000/hello/world) I got the following error:

ActionController::RoutingError (No route matches “/hello/world”):

Do I need to make changes to the routes.rb file? If so, what changes?

Thank you.

first follow the MVC convention of writing correct rails code, put view  
code in the views. get out of the habit now to write view code in the  
controller, the controller should be kept lean and mean as possible

try putting the following line in routes.rb

get ‘hello/world’

you are trying yo use this ====\> match  
‘:controller(/:action(/:id(.:format)))’

read!

# This is a legacy wild controller route that’s not recommended for

RESTful applications.

# Note: This route will make all actions in every controller

accessible  
via GET requests.

# match ‘:controller(/:action(/:id(.:format)))’

you are trying to access an action like this

hello/world =====\> # match ‘:controller(/:action)’

with that line commented is not possible to access actions the old non  
restfull way.
