quma 0.1.0

A SQL/database library

quma is a small SQL database library for Python and PyPy version 3.5 and higher. It maps object methods to SQL script files and supports SQLite, PostgreSQL, MySQL and MariaDB.

It also provides a simple connection pool and templating for dynamic SQL like conditional WHEREs.

Motivation

Unlike ORMs, it allows to write SQL as it was intended and to use all features the DBMS provides. As it uses plain SQL files you can fully utilize your database editor or IDE to author your queries.

If you know how to best design your DDL and already have a SELECT in your mind when data needs to be retrieved, welcome, this is for you.

It gives you back your powers you so carelessly gave away to ORMs.

Installation

pip install quma

Quick Start

The full documentation is available at https://quma.readthedocs.io

Given a directory with some SQL scripts e. g.:

/path/to/sql/scripts
├── users
│    ├── all.sql
│    └── remove.sql
└── get_admin.sql

You can access these scripts after connecting to the database:

from quma import Database

db = Database('sqlite:///:memory:', '/path/to/sql/scripts')

db.execute('CREATE TABLE users ...')

with db.cursor as cur:
    all_users = cur.users.all()

    for user in all_users:
        print(user['name'])

    cur.users.remove(id=user['id']).run()
    cur.commit()

    admin = cur.get_admin().one()
