Subject: Re: conditional before_save :encrypt_password

You got the wrong Maillinglist, it's Ruby, not RoR, latter got it's own
ML, check google for the address...

Anyway, try:

before_save :encrypt_password, :if => :is_new_user?

private
def is_new_user
    new_record?
end

Of course, adjust the :is_new_user method as needed.

Greets, Chris

PS. You can also use procs instead symbols on the :if condition, useful
for simple 1 liners
:if => lambda{ new_record? }
