[Rails] #expire_fragment in models...any clean solutions?

[Derek Haynes]

I've seen a couple of workarounds on the mailing list related to
expiring cached fragments inside of models, but nothing too clean.
Anybody have any suggestions for handling this at the model-level? I
have an application is updated outside of the Rails controllers, so I
can't use a Sweeper.

The 2 methods I've seen:

a. Use a callback to generate an HTTP post on a controller action that
expires a fragment. While a little convoluted, it actually doesn't
look terribly bad, but the coupling between the controller and the
model isn't desired.

b. A home-baked solution to delete the fragments...however, there's a
lack of solid code snippets for this method.

Any other ideas?

Cheers,

Derek
