In this case, you''re looking for Rails helper modules, not Ruby
methods. If
you haven''t already, check out
ActiveSupport::CoreExtensions::Time::Calculations for more of them.

next_week works on a Time object and the_event.start_on is apparently a
String object. If you''re intentionally storing it as a String, you
could
use the to_time conversion before applying the next_week method.
C:\InstantRails-1.5\rails_apps\sandbox>ruby script\console
Loading development environment.>> event=Time.now
=> Mon Mar 26 11:26:25 -0500 2007>> event_string = event.to_s
=> "Mon Mar 26 11:26:25 -0500 2007">> event_string.to_time.next_week
