In the following code, I assume there's a cache_key_for method defined in ApplicationHelper that's being used by the Rails app to compute the key used for caching the asset objects. If that isn't the case in your app, you won't need the helper calls, but you'll need to supply whatever code you're actually using for determining cache key values.

in Rails console:

controller = ApplicationController.new
controller.expire_fragment(helper.cache_key_for(asset))

in other code (where the "helper" method is not defined):

include ApplicationHelper
controller = ApplicationController.new

controller.expire_fragment(cache_key_for(asset))

# Redefine Time.now to be one day earlier than the real thing.
# N.B. Using the "alias" keyword does not work correctly -- in the following, it would cause infinite stack recursion.  Cf. http://www.ruby-forum.com/topic/135598
