PLWRAP - asyncpg
plwrap is an easy to use wrapper for Postgresql orientend on jdbi. It is not an ORM, instead it allows to run SQL queries and dump the result into consistent Python Objects (Dataclasses are prefered)
SQL is awesome. Try to remember! :-)
Sanic integration
When used together with sanic, plwrap uses the sanic logging framework for debugging queries
Examples
import asyncio
from dataclasses import dataclass
import asyncpg
from plwrap import query, one
@dataclass
class User:
""" User store """
id: str
email: str
pwhash: str
class UserDAO:
""" some sort of database access object """
@staticmethod
@one
@query(User)
async def get_by_email(email: str) -> User:
""" Tries to get a user based on its email (unique) """
return "select id, email, pwhash from users where email = $1", email
async def main():
db_pool = await asyncpg.create_pool(database="what", user="ever")
user = await UserDAO.get_by_email(db_pool, "me@xvzf.tech")
print(user)
if __name__ == "__main__":
asyncio.get_event_loop().run_until_complete(main())
