peewee-async

Asynchronous interface for peewee ORM powered by asyncio.

Overview

• Requires Python 3.8+
• Has support for PostgreSQL via aiopg
• Has support for MySQL via aiomysql
• Asynchronous analogues of peewee sync methods with prefix aio_
• Drop-in replacement for sync code, sync will remain sync
• Basic operations are supported
• Transactions support is present

The complete documentation:
http://peewee-async-lib.readthedocs.io

Install

Install with pip for PostgreSQL:

pip install peewee-async[postgresql]

or for MySQL:

pip install peewee-async[mysql]

Quickstart

Create 'test' PostgreSQL database for running this snippet:

createdb -E utf-8 test

import asyncio
import peewee
import peewee_async

# Nothing special, just define model and database:

database = peewee_async.PooledPostgresqlDatabase(
    database='db_name',
    user='user',
    host='127.0.0.1',
    port='5432',
    password='password',
)

class TestModel(peewee_async.AioModel):
    text = peewee.CharField()

    class Meta:
        database = database

# Look, sync code is working!

TestModel.create_table(True)
TestModel.create(text="Yo, I can do it sync!")
database.close()

# No need for sync anymore!

database.set_allow_sync(False)

async def handler():
    await TestModel.aio_create(text="Not bad. Watch this, I'm async!")
    all_objects = await TestModel.select().aio_execute()
    for obj in all_objects:
        print(obj.text)

loop = asyncio.get_event_loop()
loop.run_until_complete(handler())
loop.close()

# Clean up, can do it sync again:
with database.allow_sync():
    TestModel.drop_table(True)

# Expected output:
# Yo, I can do it sync!
# Not bad. Watch this, I'm async!
