Order of the state_machine callback chain and how to abort it

  1. before transition
  2. before validation
  3. after validation
  4. before save
  5. after save
  6. after transition

Aborting the callback chain

  • You can interrupt the callback chain by returning false in before_transition.
  • You can not prevent the record from being saved by manually adding an validation error during before_transition.
  • You can rollback the database update by raising an error in after_transition. The error will bubble up to the caller, no changes will be saved.
  • You can not interrupt the callback chain by returning false in after_transition.
