DynamoDB Dynomite Model Callbacks
Dynomite provides support for callbacks by leveraging ActiveModel.
These callbacks are supported:
- save (before, after, around)
- create (before, after, around)
- update (before, after, around)
- validation (before, after)
- destroy (before, after, around)
- touch (after)
- initialize (after)

end
