I am getting "undefined method 'authenticate' for User:Class" even tho I
do have it defined in my User class. I put some puts to see how far the
code in user.rb was being executed when declaring the class and it seems
that it breaks when reaching the acts_as_authorized_user line, however
rails does not spit any error it just doesn't finish loading the User
class. Here is the code:

puts "*Going to define User"
class User < ActiveRecord::Base

puts "*Going to include"
puts "*Done include"
# Virtual attribute for the unencrypted password
attr_accessor :password

validates_presence_of :login, :email
validates_presence_of :password, :if => :password_required?
validates_presence_of :password_confirmation, :if => :password_required?
validates_length_of :password, :within => 4..40, :if =>
validates_confirmation_of :password, :if => :password_required?
validates_length_of :login, :within => 3..40
validates_length_of :email, :within => 3..100
validates_uniqueness_of :login, :email, :case_sensitive => false
before_save :encrypt_password

# Authenticates a user by their login name and unencrypted password.
Returns the user or nil.
def self.authenticate(login, password)
u = find_by_login(login) # need to get the salt
u && u.authenticated?(password) ? u : nil

# Encrypts some data with the salt.
def self.encrypt(password, salt)

# Encrypts the password with the user salt
def encrypt(password)
self.class.encrypt(password, salt)

def authenticated?(password)
crypted_password == encrypt(password)

def remember_token?
remember_token_expires_at && < remember_token_expires_at

# These create and unset the fields required for remembering users
between browser closes
def remember_me
self.remember_token_expires_at = 2.weeks.from_now.utc
self.remember_token = encrypt("#{email}--#{remember_token_expires_at}")

def forget_me
self.remember_token_expires_at = nil
self.remember_token = nil

# Defining has_role? is optional when you use 'acts_as_authorized_user'.
# You can check roles against hardwired names before passing it off to

def has_role?( role, authorized_object = nil )
return true if self.username.downcase == 'admin' and (role ==
#return true if self.username.downcase == 'nobody' and role == 'nobody'
# Note that no 'conquerer' role is hardwired in, so it must be in role
table & checked through mixin has_role? method.

# before filter
def encrypt_password
return if password.blank?
self.salt = Digest::SHA1.hexdigest("--#{}--#{login}--") if
self.crypted_password = encrypt(password)

def password_required?
crypted_password.blank? || !password.blank?

puts "*Done defining User"

Any suggestions on what I can do? I am using rails 1.2.3 and rails

Are you including the module that mixes in the functionality for

yes, I tried doing
include Authorization::ObjectRolesTable::UserExtensions::ClassMethods
include Authorization::ObjectRolesTable::ModelExtensions::ClassMethods

on the User class but that didn't work either, it gives me the same
error. Using the puts I can see that rails stops loading the class at
those lines, so I am starting to suspect that the Plugin classes are not
being loaded by rails or it can't find them. However, I put some puts on
the load_plugins method of rails and it does have the correct paths for
my plugins.  I am absolutely confused at this point.

Does this plugin have docs? What plugin is it? You're absolutely
it's not loading the plugins

The authorization plugin, I am also using the acts_as_authenticated
plugin and the Dr. Nick Magic models. I tried deactivating the Magic
Models plugin but it made no difference.

I am not using the authorization plugin anymore, but the models are
still not being loaded properly. For example I have a DemeritSlip class
in the models folder with a custom attribute named std_name that looks
like this:

def std_name=(std_formal_and_id)
  def set_std_name(std_formal_and_id)
    self.student_id = std_formal_and_id.to_s.split("ID:")[1].to_i
  def std_name
    if (self.student == nil)
      return ""
      return self.student.formal_name_id

Rails doesn't find this method somehow.
