name	aquilia-database-orm-migrations
description	Build Aquilia database, sqlite, ORM model, query, transaction, and migration workflows. Use for DatabaseIntegration, typed DB configs, AquiliaDatabase, native sqlite, Model fields/managers, makemigrations/migrate/sqlmigrate/inspectdb/status, and schema snapshots.

Aquilia Database Orm Migrations

Purpose

Implement and debug Aquilia database and model workflows from typed config through migrations.

Trigger Conditions

Use for Workspace.database, Integration.database, SqliteConfig/PostgresConfig/MysqlConfig/OracleConfig, AquiliaDatabase, native sqlite, Model subclasses, fields, querysets, transactions, and aq db commands.

Inputs

• Database URL or typed config.
• Model classes and fields.
• Migration directory, app filter, database alias, and whether to emit DSL or SQL.

Execution Flow

1. Configure DB globally through Workspace.database(...) or Integration.database(config=...).
2. Define models as Python Model subclasses with fields from aquilia.models.
3. Use async query APIs such as Model.objects.filter(...).all(), Model.create(...), and transaction helpers.
4. Generate migrations with aq db makemigrations; apply with aq db migrate; inspect with showmigrations, sqlmigrate, status, or inspectdb.
5. For sqlite internals, use native aquilia.sqlite rather than deprecated aiosqlite paths.

Constraints

• Use parameterized query APIs; do not construct SQL with untrusted field/table names.
• Manifest-level database config is deprecated and ignored at runtime.
• Migration snapshots use Crous binary where available; do not hand-edit unless necessary.

Implementation Anchors

aquilia/db/configs.py, aquilia/db/engine.py, aquilia/sqlite/, aquilia/models/base.py, aquilia/models/fields_module.py, aquilia/models/migration_gen.py, aquilia/cli/commands/model_cmds.py, examples/sqlite_inventory_app/.

Examples

• Add SqliteConfig(path="runtime/app.db", auto_create=True) to a workspace.
• Create class Project(Model): key = CharField(max_length=64, unique=True).
• Run aq db makemigrations --app inventory then aq db migrate --plan.

Failure Handling

Unsupported URLs raise database connection faults. Field validation raises FieldValidationFault. If startup guard complains about migrations, generate/apply migrations or set an explicit development auto-migration policy.
