override to_param + restful_authentication

To all:


i think i realise what i went wrong here at http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/47c3b56034adf347/265b30d3cd97e137?lnk=gst&q=restful_authentication+nested#

I think its all due to the problem of me using restful authentication and override to_param method with a

# overriding to_param method to use permalink instead of id   def to_param     self.permalink   end

inside my User model (user.rb)

to make my urls look like localhost:3000/users/peter_login/orders

rather than localhost:3000/users/2/orders

How do i reconcile getting more meaningful urls with restful authentication?

Thank you.
