Module: ChronoForge::Generators::MigrationActions

Included in:
InstallGenerator, UpgradeGenerator
Defined in:
lib/generators/chrono_forge/migration_actions.rb

Overview

Shared migration-copy logic for the install and upgrade generators.

Copying is idempotent: a migration whose name already exists in the host application’s db/migrate is skipped, so it is safe to re-run either generator. ‘install` copies the full set (a fresh app has none yet); `upgrade` copies only the migrations a previously-installed app is missing. Both share this method — the difference is purely which migrations already exist in the target app.

MIGRATIONS is listed in application order; copying preserves that order because each migration_template assigns the next sequential version number.
