Module: Provenance::Trackers::BulkOperations

Defined in:
lib/provenance/trackers/bulk_operations.rb

Overview

Intercepts bulk operations (‘update_all`/`delete_all`) which bypass ActiveRecord callbacks and therefore never reach the regular Trackable path. Captures the ids of the affected rows before execution and records the change in the journal.
