Working with Authlogic in script/console

with 6 comments

When probing / debugging issues with Authlogic on rails console, you want to be able to create UserSessions and authenticate just like a live app does. However, you may run into issues if you plainly try to instantiate and save UserSession objects in console.

>> UserSession.new(:email => "validemail@domain.com", :password => "password")
Authlogic::Session::Activation::NotActivatedError: You must activate the Authlogic::Session::Base.controller with a controller object before creating objects
	from /var/lib/gems/1.8/gems/authlogic-2.1.1/lib/authlogic/session/activation.rb:47:in `initialize'
	from /var/lib/gems/1.8/gems/authlogic-2.1.1/lib/authlogic/session/klass.rb:61:in `initialize'
	from /var/lib/gems/1.8/gems/authlogic-2.1.1/lib/authlogic/session/scopes.rb:79:in `initialize'
	from (irb):2:in `new'
	from (irb):2

Authlogic uses framework adapters (RailsAdapter or MerbAdapter) to extract information such as session/cookies when working on authentication stuff. In order to enable this same mechanism for rails console, you need to do the following inside console:

>> Authlogic::Session::Base.controller = Authlogic::ControllerAdapters::RailsAdapter.new(self)

After this, you should be able to create UserSession objects like you normally would:

>> us = UserSession.new(:email => "validemail@domain.com", :password => "password")
=> #<UserSession: {:password="<protected", :email="validemail@domain.com"}>
>> us.save!
  User Load (0.6ms)   SELECT * FROM `users` WHERE (LOWER(`users`.email) = 'validemail@domain.com') LIMIT 1
  SQL (0.2ms)   BEGIN
  User Update (0.4ms)   UPDATE `users` SET `failed_login_count` = 2, `updated_at` = '2009-09-25 02:31:57', `perishable_token` = 'bP_s1_z9gwCFmrIX9cdV' WHERE `id` = 1
  SQL (1706.2ms)   COMMIT
Authlogic::Session::Existence::SessionInvalidError: Your session is invalid and has the following errors: Password is not valid
	from /var/lib/gems/1.8/gems/authlogic-2.1.1/lib/authlogic/session/existence.rb:85:in `save!'
	from (irb):11

2. Great fix! It’s great to be able to hop over to script/console to to some quick exploratory tests.

   Question: Can is it possible to search for *all* logged_in users from script console without touching the User table? Does the UserSession model support this?

4. Good question. UserSession provides a ActiveRecord like interface to cookies/session. However, I don’t believe there is any static find* methods that would give us the aggregate information, atleast not directly.

   You might want to crack open the gem files and see if there is any such thing built in. Or else the other option is to use :last_accessed_at and other magic columns on User model to figure out currently logged in users…

5. Hi,

   By any chance, do you have the same fix, but for backgroundrb ? Because I’m getting the exact same error, (You must activate the Authlogic::Session::Base.controller with a controller object before creating objects), but within the context of backgroundrb (see http://osdir.com/ml/authlogic/2009-12/msg00014.html)

   Thank you.
