Usage examples


import asyncio
from sqlalchemy import Integer, Column, String, ForeignKey
from asyncsa.manager.async_pg import PostgresManager
from asyncsa.model.mixin import Mixin
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import relationship
from sqlalchemy.sql import select

dsn = "postgres://postgres:test@localhost:2345/test"

conf = {'dsn': dsn}

Base = declarative_base()


Manager = PostgresManager(conf=conf)


class User(Mixin, Base):

    _manager = Manager

    __tablename__ = 'test'
    id = Column(Integer, autoincrement=True,  primary_key=True)
    name = Column(String(50))

    def __repr__(self):
        return "<User(name='%s', id='%s')>" % (
            self.name, self.id)


class Parent(Mixin, Base):
    __tablename__ = 'parent'
    _manager = Manager
    id = Column(Integer, primary_key=True)
    child = relationship("Child", lazy='joined')


class Child(Mixin, Base):
    _manager = Manager
    __tablename__ = 'child'
    id = Column(Integer, primary_key=True)
    parent_id = Column(Integer, ForeignKey('parent.id'))
    parent = relationship("Parent", back_populates="child")


if __name__ == '__main__':

    loop = asyncio.get_event_loop()
    loop.run_until_complete(Manager.connect())

    result = loop.run_until_complete(Manager.get(
        User.objects([User.id]).join(
            Parent.__table__,
            Parent.id == User.id)))
    print(result)

    # result = loop.run_until_complete(Child.create_table())
    # print(result)
    # u = loop.run_until_complete(User.create(name='test'))
    # print('create', u)
    # print('get', loop.run_until_complete(User.get(name='test')))
    # print('all', loop.run_until_complete(User.all()))
    # u.name = 'aaa'
    # print('save', loop.run_until_complete(u.save()))
