Module: Collavre::Creatives::EffectiveCreativeResolution

Defined in:
app/services/collavre/creatives/effective_creative_resolution.rb

Overview

Single source of truth for "which creative's cache/ownership actually governs permission for this creative?".

A linked creative (origin_id present) borrows its origin's permission: it has no cache entries of its own and its ownership is the origin's ownership. PermissionChecker (single-item) and PermissionFilter (batch) MUST resolve the effective creative through this module so a single check and a batch filter can never diverge for the same user + linked creative.

Class Method Details

.effective_creative(creative) ⇒ Object

For a single loaded creative: returns the creative whose cache/ownership governs permission. Non-linked creatives resolve to themselves.

def effective_creative(creative)
  creative.origin_id.nil? ? creative : creative.origin
end

.effective_creative_ids(ids) ⇒ Object

For a batch of creative ids: returns { original_id => effective_id }. Linked creatives map to their origin_id; every other id (including ids not found in the table) maps to itself. This mirrors effective_creative so the batch reader resolves origin identically.

def effective_creative_ids(ids)
  # Coerce to Integer: origin_by_id is keyed by integer ids from pluck, so a
  # string id (e.g. sourced from request params) would miss origin lookup
  # and later miss the integer-keyed readable Set. Non-numeric ids can't
  # identify a Creative, so drop them.
  ids = ids.to_a.filter_map { |id| Integer(id, exception: false) }.uniq
  return {} if ids.empty?

  origin_by_id = Creative.where(id: ids).pluck(:id, :origin_id).to_h
  ids.index_with { |id| origin_by_id[id] || id }
