A number of Rails 2.3 apps are using Restful Authentication but that plugin seems to have some issues with Rails 3. In upgrading to Rails 3 I have been using Devise. Is there any way to smoothly transition from Restful Authentication to Devise? Has anyone done a migration that shows how to update the User model?

In my case it works (analized authentication.rb and by_password.rb in old gem restful_authentication):
config/initializers/devise.rb add this:
config.encryptor = :restful_authentication
config.stretches = 10 #REST_AUTH_DIGEST_STRETCHES frome Restful Authentication file config/initializers/site_key.rb
config.pepper = 'mashauronilavrechkumyachik' #REST_AUTH_SITE_KEY frome Restful Authentication file config/initializers/site_key.rb
app/models/user.rb add :encryptable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:encryptable, :omniauthable, :authentication_keys => [:login]
config/initializers/devise_encryptor.rb create with this this:
# -*- encoding : utf-8 -*-
require "digest/sha1"
module Devise
module Encryptable
module Encryptors
class RestfulAuthentication < Base
def self.digest(password, stretches, salt, pepper)
digest = pepper
stretches.times do
digest = secure_digest(digest, salt, password, pepper)
end
digest
end
def self.secure_digest(*args)
Digest::SHA1.hexdigest(args.flatten.join('--'))
end
def self.encrypt_password
return if password.blank?
self.password_salt = make_token if new_record?
self.encrypted_password = encrypt(password)
end
def self.make_token
secure_digest(Time.now, (1..10).map{ rand.to_s })
end
def self.encrypt(password)
self.password_digest(password, stretches, salt, pepper)
end
end
end
end
end

Here is a good guide on migration from restful_authentication to devise

I was having problems with the password encryption (but I found the answer, see my other response). The old app used an old version of Restful Authentication. It was handling the password encryption like so:
# before filter
def encrypt_password
return if password.blank?
self.salt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") if new_record?
self.crypted_password = encrypt(password)
end
# Encrypts some data with the salt.
def self.encrypt(password, salt)
Digest::SHA1.hexdigest("--#{salt}--#{password}--")
end
# Encrypts the password with the user salt
def encrypt(password)
self.class.encrypt(password, salt)
end
If I set Devise's config.encryptor
to :restful_authentication_sha1
it doesn't work.

Here's how to overcome the password problem:
You need to make a custom encryptor like so:
# /config/initializers/devise_encryptor.rb
require "digest/sha1"
module Devise
module Encryptors
class OldRestfulAuthentication < Base
def self.digest(password, stretches, salt, pepper)
Digest::SHA1.hexdigest("--#{salt}--#{password}--")
end
end
end
end
And then choose it in devise.rb
like so:
config.encryptor = :old_restful_authentication
That should do it!

I updated my application from Restful Authentication to Devise already. Here is my migration:
class AlterUsersForDevise < ActiveRecord::Migration
def self.up
remove_column :users, :name
change_column :users, :email, :string, :default => "", :null => false, :limit => 128
rename_column :users, :crypted_password, :encrypted_password
change_column :users, :encrypted_password, :string, :limit => 128, :default => "", :null => false
rename_column :users, :salt, :password_salt
change_column :users, :password_salt, :string, :default => "", :null => false, :limit => 255
add_column :users, :reset_password_token, :string
change_column :users, :remember_token, :string, :limit => 255
rename_column :users, :remember_token_expires_at, :remember_created_at
add_column :users, :sign_in_count, :integer, :default => 0
add_column :users, :current_sign_in_at, :datetime
add_column :users, :last_sign_in_at, :datetime
add_column :users, :current_sign_in_ip, :string
add_column :users, :last_sign_in_ip, :string
rename_column :users, :activation_code, :confirmation_token
change_column :users, :confirmation_token, :string, :limit => 255
rename_column :users, :activated_at, :confirmed_at
add_column :users, :confirmation_sent_at, :datetime
end
def self.down
add_column :users, :name, :string, :limit => 100, :default => ""
rename_column :users, :encrypted_password, :crypted_password
change_column :users, :crypted_password, :string, :limit => 40
rename_column :users, :password_salt, :salt
change_column :users, :salt, :string, :limit => 40
remove_column :users, :reset_password_token
change_column :users, :remember_token, :string, :limit => 40
rename_column :users, :remember_created_at, :remember_token_expires_at
remove_column :users, :sign_in_count
remove_column :users, :current_sign_in_at
remove_column :users, :last_sign_in_at
remove_column :users, :current_sign_in_ip
remove_column :users, :last_sign_in_ip
rename_column :users, :confirmation_token, :activation_code
change_column :users, :confirmation_token, :string, :limit => 40
rename_column :users, :confirmed_at, :activated_at
remove_column :users, :confirmation_sent_at
end
end
My application isn't live so far. So i use the password encryption from Devise instead the one from Restful Authorization. If you application is already alive, and you have active users you should configure Devise to use SHA1 from Restful Authentication to en- and decrypt passwords. Otherwise all your users must request a new password.
You can configure this in the devise initializer.
Hope that helps...
