Hmm..not sure what the problem with the code is...if you''re interested
in a fast login system, you can try the acts_as_authenticated plugin.
Just type sudo ruby script/plugin install
http://svn.techno-weenie.net/projects/plugins/acts_as_authenticated/
Then in your application.rb file, you can just type:
include AuthenticatedSystem and before_filter :login_from_cookie
With it installed, you get some scripts to generate things. So:
ruby script/generate authenticated user account
gives you some migrations and some views to play around with.
On the other hand, if you want to build it homegrown, I totally
understand.

You can then put before_filter :login_required before any controller
you want password protected.
