Just put the following into your environments (the period before the domain name is the key here)

COOKIE_DOMAIN = '.yourdomain'

if ActionController::Base.session
  ActionController::Base.session[:domain] = COOKIE_DOMAIN
else
  ActionController::Base.session = { :domain => COOKIE_DOMAIN }
end

And put the following into config/initializers/clearance_override.rb and restart and you should be golden.

Clearance::Authentication::InstanceMethods.module_eval do
  def remember(user)
    user.remember_me!
    cookies[:remember_token] = { :value   => user.token,
                                 :expires => user.token_expires_at,
                                 :domain => COOKIE_DOMAIN }
  end

  def forget(user)
    user.forget_me! if user
    cookies.delete(:remember_token, :domain => COOKIE_DOMAIN)
    reset_session
  end
end

Infocow connects young people with useful stuff to help take control of life - sites, stories, information and inspiration.

Worked on the front end code and UI design with Nicolas Alpi and Ed Davey developing the back end on this project for Futurelab. Was a great experience with lots of brilliant feedback and user testing done by Futurelab feeding into the Agile development methodology we use here at Jiva.

The private beta is now live and we are looking for students and tutors to start testing.
