#paper_trail_update_column_using_value_from_changes(name, changes: changes(), touch: true) ⇒ Object

Workaround to prevent paper_trail from incorrectly recording a change from new value to new value. Useful if you've already set the attribute to the new value and now you want to save that change to the database, with versioning.
