#anonymizable(*fields, with:, stamp: UNSET, clear_audit_trail: UNSET, prefix: nil, suffix: nil) ⇒ Object

Declare fields and their erasure strategy. Repeatable — field rules merge across calls; stamp:/clear_audit_trail:/prefix:/suffix: apply only when explicitly passed (last explicit value wins).

Raises:

  • (ArgumentError)

#anonymize_all! ⇒ Object

Anonymize every matching record that isn't already stamped, in one transaction. Returns the Integer count of records anonymized (the 1.22 batch contract). Without a stamp column every record matches. Streams in PK batches (find_each) rather than loading the relation, filters stamped rows DB-side, and skips the per-record reload — the batch discards its instances, so reloading each one would cost a wasted SELECT per row.
