Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

We refer to times in the lifecycle of a record as “events”. There are three events:

  • create

    • ‘after_create` we call `RecordTrail#record_create`

  • update

    • ‘after_update` we call `RecordTrail#record_update`

    • ‘after_touch` we call `RecordTrail#record_update`

    • ‘RecordTrail#save_with_version` calls `RecordTrail#record_update`

    • ‘RecordTrail#update_columns` is also referred to as an update, though it uses `RecordTrail#record_update_columns` rather than `RecordTrail#record_update`

  • destroy

    • ‘before_destroy` or `after_destroy` we call `RecordTrail#record_destroy`

The value inserted into the ‘event` column of the versions table can also be overridden by the user, with `paper_trail_event`.

#changed_notably? ⇒ Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.
