We have an application that gets its data from a series of daemons that go out and read in data. This works great, except, we are caching pages. And I'd like to expire those pages based on an update.
It turns out that an Observer doesn't have access to expire_action or fragment. And a Sweeper is not called from data-only (i.e non-controller) updates! Buggers!
But there is a solution. You can call the sweeper directly from your importer:
MySweeper.instance.clean_up(model_instance)
This works, except I couldn't get it reliably to expire the actions. So, I used direct calls to Rails.cache.delete to do this.
Thinking about it, I guess I could then have just written an observer! As those do get called from controller-less updates.
