Logging out feature,

Code:

def logout
@title = "Login - Books"

session[:user_id] != nil
flash[:notice] = "You have sucessfully been logged out !"
redirect_to :controller => :books, :action => :index
end
end

^^when this is run, it logs the user out (nill) and displays you have
successfully been logged out,

Code v2:
def logout
@title = "Login - Books"

session[:user_id] != nil
flash[:notice] = "You have sucessfully been logged out
#{@user.screen_name} !"
redirect_to :controller => :books, :action => :index
end
end

^^what i was hoping this would do is to display the users name as well,
(this is another task), i understand the session but how can i bring the
session back while the session is nill :S

thanks once again mates,
