In your AR model, if you do this

after_update :do_foo, :if => :bar_changed?
after_update :do_foo, :if => :qux_changed?

The method #do_foo will only be called after an update where qux has changed, not one where only bar has changed. The callbacks are keyed by the methods they call, so the second callback overwrites the first one entirely.
