Audit record has no user on first request posted to a server

[dchelimsky]

This happens in an app that uses acts_as_audited and relies on controller.current_user to provide the user to the Audit record. Steps to reproduce:

1. start the server
2. navigate to an edit form for an audited model
3. re-start the server
4. post the form

The audit record has no user.

This is happening because on line 28 of audit_sweeper.rb, the controller is nil.

The reason controller is nil is that the before hook on line 8 in action_controller/caching/sweeper.rb, which assigns the current controller to the @controller instance variable, is not called on the first request.

We were able to work around this issue in our app with the following addition to our ApplicationController.

require 'acts_as_audited/audit'
require 'acts_as_audited/audit_sweeper'
cache_sweeper :audit_sweeper, :only => [:create, :update, :destroy]

VERSIONS:

rails-2.3.5
acts_as_audited-1.1.1
ree-1.8.7-2010.01

Thanks for reporting David !

I've tested this on the new Rails 3 branch (discussed in #30) and cannot get the same behavour (luckily). Should we attempt to fix this on the old branch or are you fine with documenting it as a caveat in that branch's readme ?

Given the easy workaround, I'd say documenting it is fine.
