Rails Routing

I have a profiles controller and added a method named student_add. I
would like to access this method via:

http://localhost/profiles/add/student

However, when I add the route "map.connect 'profiles/student/
add', :controller => 'profile', :action => 'student_add'

I am given the following error:

Unknown action
No action responded to add

Obviously I'm doing something wrong here. I would like to have a few
different methods in my profiles controller and access them each with

http://localhost/profiles/add/

such as

http://localhost/profiles/add/student
http://localhost/profiles/add/partner
http://localhost/profiles/add/faculty

Am I going about the method/routing the wrong way?

The controller should be plural

:controller => 'profiles'
