<p>The first thing to do is add the required methods in lib/authenticated_system.rb. This goes by the account_location default of using an Account model with a #username field for the subdomain name.</p> 1. module AuthenticatedSystem 2. protected 3. # Example of integration with account_location plugin: 4. def account? 5. @account ||= Account.find_by_username(account_subdomain) 6. end 7. 8. # use this method in a before_filter like #login_required 9. def account_required 10. return true if account? 11. redirect_to(:controller =&gt; &#8216;/account&#8217;, :action =&gt; &#8216;index&#8217;) and return false 12. end 13. end <p>html | txt</p> <p>Now, when logging in we need to record what domain the user has been authenticated on. You can do this by modifying the #current_user methods:</p> 1. # still in AuthenticatedSystem&#8230; 2. def logged_in? 3. # Only count the user as logged in if the subdomain matches 4. session[account_subdomain] == :authenticated &amp;&amp; current_user 5. end 6. 7. # Filter the available users to the current account. 8. # This assumes that Account has_many :users 9. def current_user 10. @current_user ||= session[:user] ? @account.users.find_by_id(session[:user]) : nil 11. end 12. 13. # Store the user id in the session, as well as the current sub domain. 14. def current_user=(new_user) 15. # Example of integration with account_location plugin: 16. session[account_subdomain] = new_user.nil? ? nil : :authenticated 17. session[:user] = new_user.nil? ? nil : new_user.id 18. @current_user = new_user 19. end <p>html | txt</p> <p>Be sure to add #account? to the to the list of helper methods:</p> 1. # The bottom of AuthenticatedSystem&#8230; 2. def self.included(base) 3. base.send :helper_method, :current_user, :logged_in?, :account? 4. end 2008-10-24T03:38:10-07:00 71688 integrating-the-account_location-plugin-with-acts_as_authenticated 67186 2008-10-24T03:38:10-07:00 30799
