# Peewee-AIO
Async support for [Peewee ORM](https://github.com/coleifer/peewee)
[](https://github.com/klen/peewee-aio/actions)
[](https://pypi.org/project/peewee-aio/)
[](https://pypi.org/project/peewee-aio/)
## Features
* Make [Peewee ORM](https://github.com/coleifer/peewee) to work async
* Supports PostgresQL, MySQL, SQLite
* Supports [asyncio](https://docs.python.org/3/library/asyncio.html) and
[trio](https://github.com/python-trio/trio)
* Contains types as well
* Drivers supported:
- [aiosqlite](https://github.com/omnilib/aiosqlite)
- [aiomysql](https://github.com/aio-libs/aiomysql)
- [aiopg](https://github.com/aio-libs/aiopg)
- [asyncpg](https://github.com/MagicStack/asyncpg)
- [triopg](https://github.com/python-trio/triopg)
- [trio_mysql](https://github.com/python-trio/trio-mysql)
## Requirements
* python >= 3.8
## Installation
**peewee-aio** should be installed using pip:
```shell
$ pip install peewee-aio
```
You can install optional database drivers with:
```shell
$ pip install peewee-aio[aiosqlite] # for SQLite (asyncio)
$ pip install peewee-aio[aiomysql] # for MySQL (asyncio)
$ pip install peewee-aio[aiopg] # for Postgresql (asyncio)
$ pip install peewee-aio[asyncpg] # for Postgresql (asyncio)
$ pip install peewee-aio[trio_mysql] # for MySQL (trio)
$ pip install peewee-aio[triopg] # for PostgresQL (trio)
```
### Quickstart
```python
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`):
```python
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
```python
# 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
```
