I usually combine blame with the acts_as_versioned or acts_as_audited plugins when I need to track record updates.

Can you have it output messages to syslog or another logging facility as well?

Ah, yes. That makes sense! It’s pretty close to what I ended up doing.
Thanks,
And thanks for Blame, it’s made my life easier.

Stuart, Sorry, I guess that's not a well thought out example. So, again off the top of my head... :-) You can do something similar to the default behavior. The default implementation of userstamp_object is:

def userstamp_object
  User.current_user
end

This simply requires that you add a class accessor to the model:

class User < ActiveRecord::Base
  cattr_accessor :current_user
end

Then, once the user logs in and you have access to the session, you can add a before_filter to ApplicationController:

class ApplicationController  :logged_in?

  def get_current_user
    User.current_user = User.find(session[:user_id])
  end

  def logged_in?
     !session[:user_id].nil?
  end
end

I'll update the post with a better example. Cheers, Keith

The code below does not seem to work.
ActiveRecord’s not available at this point. It works in my init.rb…except it would seem that
the session variable is not available in an ActiveRecord model.
Have I done something wrong?

# In environment.rb
class ActiveRecord::Base
  def userstamp_object
    User.find(session[:user_id])
  end
end
