Rails SHA1 issue

Has anyone used the SHA1 hash in Rails on DH? I can't get it to work. In my code:

Digest::SHA1.hexdigest(password)

Causes an "Application Error (Rails)", and I see this in the log:

NameError (uninitialized constant SHA1):

Digest is part of the Ruby standard lib, so this should work with no trouble. Anyone know what's going on here?

anyone know how i can include the Digest::SHA1 method on my own so this works?

Try this:

  require 'digest/sha1'

That's working for me.
