Module: ActiveStorage::AwsRecord::Persistence

Extended by:
ActiveSupport::Concern
Included in:
Item
Defined in:
lib/active_storage/aws_record/persistence.rb

Overview

Generic aws-record plumbing shared by every model that participates in the Active Storage owner contract — both the gem’s own entities and the application’s owner models (which include Owner). It deliberately holds no single-table key logic (that lives in Item, mixed only into the gem’s three entities), so an application owner keeps its own key schema.

Provides: aws-record + GlobalID, the shared client, equality by class + id, changed? → aws-record dirty?, raw attribute access, and helpers to mark an instance persisted/destroyed after a raw write.

def ==(other)
  other.instance_of?(self.class) && id.present? && id == other.id
end

#changed? ⇒ Boolean

Active Storage’s generic owner path checks changed?; aws-record names the same concept dirty?.

Returns:

  • (Boolean)
