With the whole ARel integration I wonder if hooking into the DB calls
just got harder or easier. I haven't had a chance to dig for a
solution yet but if someone is already working on this please chime
in. Thanks!
Today I launched a new write-through-cache gem for Rails 3, see
https://github.com/orslumen/record-cache. It's works great in Rails
3.0.x and will support Rails 3.1.x in the near future.
The reason I built it, is because we were using cache money and recently
migrated to Rails 3. So chances are, it will also serve you well.
