Auth Module

The UmlautAuth module extends functionality available from the [Authlogic|http://github.com/binarylogic/authlogic] (version 2.1.0) gem and configured as a plugin based on the [Authlogic OpenID add-on|http://github.com/binarylogic/authlogic_openid].

Core Umlaut Files Added or Updated

Several core Umlaut files were updated in order to develop the UmlautAuth module.

• app/controller/application.rb

The application controller was updated to filter passwords and provide two methods for accessing the current user session and the current user. The method current_user_session (aliased as has_logged_in_user) returns nil if no user session has been established. The method current_user (aliased as logged_in_user) return either nil or the current logged in user.

• app/controllers/user_sessions_controller.rb

The user sessions controller manages the routing of user session requests. Three methods are available:

• 1. new - renders the login screen or redirects to external login screen
  2. validate - validates the user upon login
  3. destroy - processes logout
• app/controllers/users_controller.rb

The users controller manages the routing of user related requests. Two methods are available:

• 1. edit (also called from show) - renders the user preferences screen.
  2. update - processes updates to user preferences.
• app/models/user_sessions

Extends Authlogic::Session::Base

• app/models/user

Serializes user_attributes and adds acts_as_authentic functionality to leverage the Authlogic gem. Also sets to_param to username rather than id for prettier urls.

• app/views/user_sessions/new

The default login screen

• app/views/users/edit

The default user preferences screen. Users can update mobile phone numbers and the like.

  map.validate "validate", :controller => "user_sessions", :action => "validate"
  map.resources :user_sessions
