Authlogic - how to check if a user is logged out - ruby

Question

This is my setup:
user.rb
acts_as_authentic do |c|
c.logged_in_timeout(1.minutes)
end
user_session.rb
def to_key
new_record? ? nil : [ self.send(self.class.primary_key) ]
end
self.logout_on_timeout = true
application_controller.rb
helper_method :current_user_session, :current_user
private
def current_user_session
logger.debug "ApplicationController::current_user_session"
return #current_user_session if defined?(#current_user_session)
#current_user_session = UserSession.find
end
def current_user
logger.debug "ApplicationController::current_user"
return #current_user if defined?(#current_user)
#current_user = current_user_session && current_user_session.user
end
def require_user
logger.debug "ApplicationController::require_user"
unless current_user
#store_location
flash[:warning] = "You must be logged in to access this page"
#redirect_to new_user_session_url
redirect_to root_url
return false
end
end
def require_no_user
logger.debug "ApplicationController::require_no_user"
if current_user
#store_location
flash[:warning] = "You must be logged out to access this page"
redirect_to account_url
return false
end
end
But when I load my page, I will get the error
undefined method `logged_out?' for #<User:0x00000103ee8348>
I try to read the official GitHub page of Authlogic, but I still don't know, what I miss... Could anyone give me a tip for fix it?
Many thanks in advance!

I was having the exact same problem, and it boiled down to the fact I didn't have all of the necessary columns in my User model.
My original User model (from db/schema.rb) was pretty minimalistic:
create_table "users", :force => true do |t|
t.string "username"
t.string "name"
t.string "crypted_password"
t.string "password_salt"
t.string "persistence_token"
t.string "perm", :default => "employee"
end
However, I added the column t.datetime :last_requested_at to my model, as well as a few others that may or may not be needed. My final User model looks like:
create_table "users", :force => true do |t|
t.string "username"
t.string "name"
t.string "crypted_password"
t.string "password_salt"
t.string "persistence_token"
t.string "perm", :default => "employee"
t.datetime "created_at"
t.datetime "updated_at"
t.integer "login_count", :default => 0, :null => false
t.integer "failed_login_count", :default => 0, :null => false
t.datetime "last_request_at"
t.datetime "current_login_at"
t.datetime "last_login_at"
t.string "current_login_ip"
t.string "last_login_ip"
end
After adding in the other columns, I no longer get the undefined method 'logged_out?'... error.
Good luck!

If you want to know if a user is logged out, you can do:
if current_user_session
...
This condition will return true if the user is logged in (there is a session), and false if they are logged out (the session is nil).
As for the error message, undefined method 'logged_out?' for #<User:0x00000103ee8348> means that you haven't defined a method called logged_out?, so it doesn't know what you mean.
Authlogic doesn't define a logged_out? method for the User model, and neither have you, so there's nothing to call. The reason is that the state of either being "logged in" or being "logged out" doesn't have anything to do with the User model, but instead is a property of whether or not a given user has an active UserSession record.
