Features
- Make Peewee ORM to work async
- Supports PostgresQL, MySQL, SQLite
- Supports asyncio and trio
- Contains types as well
- Drivers supported:
Requirements
- python >= 3.8
Installation
peewee-aio should be installed using pip:
$ pip install peewee-aio
You can install optional database drivers with:
$ pip install peewee-aio[aiosqlite]
$ pip install peewee-aio[aiomysql]
$ pip install peewee-aio[aiopg]
$ pip install peewee-aio[asyncpg]
$ pip install peewee-aio[trio_mysql]
$ pip install peewee-aio[triopg]
Quickstart
import peewee
from peewee_aio import Manager, AIOModel, fields
manager = Manager('aiosqlite:///:memory:')
@manager.register
class Role(AIOModel):
# Pay attention that we are using fields from Peewee-AIO for better typing support
id = fields.AutoField()
name = fields.CharField()
@manager.register
class User(AIOModel):
# Pay attention that we are using fields from Peewee-AIO for better typing support
id = fields.AutoField()
name = fields.CharField()
role = fields.ForeignKeyField(Role)
async def handler():
# Initialize the database's pool (optional)
async with manager:
# Acquire a connection
async with manager.connection():
# Create the tables in database
await Role.create_table()
await User.create_table()
# Create a record
role = await Role.create(name='user')
assert role
assert role.id # role.id contains correct string type
user = await User.create(name="Andrey", role=role)
assert user
assert user.id
role = await user.role # Load role from DB using the foreign key
assert role # role has a correct Role Type
# Iterate through records
async for user in User.select(User, Role).join(Role):
assert user # user has a corrent User Type
assert user.id
role = await user.role # No DB query here, because the fk is preloaded
# Change records
user.name = "Dmitry"
await user.save()
# Update records
await User.update({"name": "Anonimous"}).where(User.id == user.id)
# Delete records
await User.delete().where(User.id == user.id)
# Drop the tables in database
await User.drop_table()
await Role.drop_table()
# Run the handler with your async library
import asyncio
asyncio.run(handler())
Usage
TODO
Sync usage
The library still supports sync mode (use manager.allow_sync):
class Test(peewee.Model):
data = peewee.CharField()
with manager.allow_sync():
Test.create_table()
Test.create(data='test')
assert Test.select().count()
Test.update(data='new-test').execute()
Get prefetched relations
TODO
# We prefetched roles here
async for user in User.select(User, Role).join(Role):
role = user.fetch(User.role) # get role from user relations cache
