Use Devise authentication for Typus 3.0

20101219150921_add_typus_attributes_to_users.rb

class AddTypusAttributesToUsers < ActiveRecord::Migration
  def self.up
    add_column :users, :role, :string
    add_column :users, :status, :boolean, :null=>false, :default=>true
    User.find(1).update_attribute(:role,'admin')
  end

  def self.down
    remove_column :users, :role
    remove_column :users, :status
  end
end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :nick, :email, :password, :password_confirmation, :remember_me

  validates_uniqueness_of :nick


  
  #
  # Typus adaptation
  #

  
  enable_as_typus_user

  ROLE = Typus::Configuration.roles.keys.sort
  LANGUAGE = Typus.locales

  def self.authenticate(email, password)
    resource = find_for_database_authentication({ :email=>email })
    resource && resource.valid_password?( password ) ? resource : nil
  end

  # Typus redefines it
  def password_required?
    true
  end
  
  def first_name
    email
  end

  def last_name
  end

  def preferences
    ''
  end

end

I guess if Typus.authentication returned 'devise_session' and there was the appropriate
Typus::Authentication::DeviseSession
class around it might work.

However there are some spots in your views where you hard code routes instead of delegating to the adapter.

----------------------
app/views/admin/helpers/_login_info.html.erb
----------------------
  1 <ul>
  2   <li><%= Typus::I18n.t("Logged as") %> <%= link_to admin_user.name, { :controller => "/admin/#{Typus.user_class.to_resource}", :action => 'edit', :id => admin_user.id } %></li>
  3   <li><%= link_to Typus::I18n.t("Sign out"), admin_session_path, :confirm => Typus::I18n.t("Are you sure you want to sign out and end your session?"), :method => :delete %></li>
  4 </ul>

for instance

  "/admin/#{Typus.user_class.to_resource}"

is the trouble bit

I started to extract the authentication mechanisms to make easier to integrate with other systems, but I must say I have never integrated devise with typus because I'm using the session mechanism.

I accept pull requests fixing that stuff, so feel free to work on that if you want.

I've pushed a branch which adds devise support to Typus.

Works well. Thanks :)
