Threadline.Capture.AuditTransaction (Threadline v0.4.0)

Copy Markdown View Source

Ecto schema for the audit_transactions table.

An AuditTransaction groups every row mutation that occurred within a single PostgreSQL transaction. Records are created automatically by the capture triggers installed by mix threadline.gen.triggers — application code does not insert them directly.

Key fields

  • :txid — the PostgreSQL transaction ID, used by the trigger to group concurrent changes safely under PgBouncer transaction-mode pooling.
  • :occurred_at — timestamp when the transaction committed (microsecond precision).
  • :actor_ref — who performed the writes. Populated from the threadline.actor_ref GUC when it is set inside the same Ecto.Repo.transaction/1 as the audited writes (see Threadline.Plug for the bridge pattern).
  • :action_id — optional FK to Threadline.Semantics.AuditAction. Set when you call Threadline.record_action/2 and link semantic intent to captured rows.
  • :source — free-form string identifying the application subsystem, for example "web" or "oban".

Relationships

  • has_many :changes, Threadline.Capture.AuditChange — the row mutations captured in this transaction.
  • belongs_to :action, Threadline.Semantics.AuditAction — optional semantic label for this transaction.

Setup

Run mix threadline.install to generate the migration that creates this table, then mix threadline.gen.triggers to register capture triggers on your application tables. See guides/domain-reference.md for the full domain model.
