Rails - Nov 2006 - #expire_fragment in models...any clean solutions?

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
