Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

	Ever wondered how to login as another user within Devise?

	Recently we had a feature request that would provide Admins with the ability
	to sign is as another user. You could imagine live demonstrations or even production
	support calls where you would like to be signed in as another user, yet not
	have to ask for or decrypt their current password. After stewing for a bit, we found a
	pretty nice solution with Devise.

	Here's the Cucumber feature...

	Host heroku.com
	HostName heroku.com
	User git
	IdentityFile ~/.ssh/heroku.identity
	IdentitiesOnly yes
