has secure password memo
# some notes on using has_secure_password
class User < ActiveRecord::Base
has_secure_password
attr_accessible :login_name, :password, :password_confirmation
# secure_password.rb already checks for presence of :password_digest
# so we can assume that a password is present if that validation passes
# and thus, we don't need to explicitly check for presence of password
