PhoenixKitManufacturing.Migrations.Machines (PhoenixKitManufacturing v0.2.0)

Copy Markdown View Source

Versioned migration for the Manufacturing module.

Creates the machines reference-book tables:

  • phoenix_kit_machines
  • phoenix_kit_machine_types
  • phoenix_kit_machine_type_assignments (join)

All statements use IF NOT EXISTS guards — safe to run multiple times.

Implements the versioned-migration protocol expected by PhoenixKit Core (mix phoenix_kit.update): current_version/0 and migrated_version_runtime/1. The host applies these by running mix phoenix_kit.update, which discovers this module via PhoenixKitManufacturing.migration_module/0, diffs the applied version against current_version/0, and generates + runs a wrapper migration. Reference implementation — PhoenixKit.Migrations.Postgres in Core.

Depends on uuid_generate_v7(), provided by core's early migrations.
