Class: Publication::Reviser

BaseService show all
Defined in:
app/services/publication/reviser.rb

Overview

Creates the next revision of a publication: deep-dups the record, bumps the
SKU revision letter, discontinues the original — and links the two through
the REAL relationship machinery:

  • +items.successor_item_id+ — the item-level succession chain (the same
    column product succession uses); readers walk this chain instead of the
    fragile "sku ILIKE '%'" pattern match, which false-matches
    across SKU prefixes (TZ-100 canonical also matched TZ-1000-A)
  • RelatedPublication.link_revision — the typed publication link with
    provenance metadata
