The orm package is an async ORM for Python, with support for Postgres, MySQL, and SQLite. ORM is built with:

• SQLAlchemy core for query building.
• databases for cross-database async support.
• typesystem for data validation.

Because ORM is built on SQLAlchemy core, you can use Alembic to provide database migrations.

Documentation: https://www.encode.io/orm

$ pip install orm

You can install the required database drivers with:

$ pip install orm[postgresql] $ pip install orm[mysql] $ pip install orm[sqlite]

Driver support is provided using one of asyncpg, aiomysql, or aiosqlite.

Note: Use ipython to try this from the console, since it supports await.

import databases import orm database = databases.Database("sqlite:///db.sqlite") models = orm.ModelRegistry(database=database) class Note(orm.Model): tablename = "notes" registry = models fields = { "id": orm.Integer(primary_key=True), "text": orm.String(max_length=100), "completed": orm.Boolean(default=False), } # Create the tables await models.create_all() await Note.objects.create(text="Buy the groceries.", completed=False) note = await Note.objects.get(id=1) print(note) # Note(id=1)
