Mongoid+Rails: Atomic callbacks?

I know that in Rails all ActiveRecord callbacks are executed inside transaction. So if something goes wrong nothing is changed/wrong. Will Mongoid gem handle this in the same way (no transactions available as far as I know)?

Thx!

There's no such thing as a transaction in mongodb, so no this won't be handled for you. Should something blow up in an after_save or something like that you'll need to fix the damage yourself.

The general approach (as the FAQ hints at) is to try and design around this by using mongo's atomic modifiers.
