Installation

Installation is as simple as:

pip install ormar

Ormar uses databases for connectivity issues, pydantic for validation and sqlalchemy-core for queries.

All three should install along the installation of ormar if not present at your system before.

The required versions are pinned in the pyproject.toml file.

Optional dependencies

ormar has three optional dependencies based on database backend you use:

pip install ormar[postgresql]

Will install also asyncpg and psycopg2.

pip install ormar[mysql]

Will install also aiomysql and pymysql.

pip install ormar[sqlite]

Will install also aiosqlite.

pip install ormar[orjson]

Will install also orjson that is much faster than builtin json parser.

pip install ormar[crypto]

Will install also cryptography that is required to work with encrypted columns.

Of course, you can also install these requirements manually with pip install asyncpg etc.
