Authlogic & Perishable token

Hi
I'm setting up authlogic and have an error:

Column 'perishable_token' cannot be null
.....
.....

Does anyone know what should generate value for this column?

Thanks in advance!

I've found:

class User < ActiveRecord::Base
  acts_as_authentic do |c|
    c.transition_from_restful_authentication = true
  end
end
