Copy and paste this code in a file and run:
from datetime import datetime
import sqlalchemy as sa
from aiohttp import web
from sqlalchemy import orm
import aiohttp_sqlalchemy as ahsa
metadata = sa.MetaData()
Base = orm.declarative_base(metadata=metadata)
class MyModel(Base):
__tablename__ = 'my_table'
pk = sa.Column(sa.Integer, primary_key=True)
timestamp = sa.Column(sa.DateTime(), default=datetime.now)
async def main(request):
sa_session = ahsa.get_session(request)
async with sa_session.begin():
sa_session.add(MyModel())
result = await sa_session.execute(sa.select(MyModel))
result = result.scalars()
data = {
instance.pk: instance.timestamp.isoformat()
for instance in result
}
return web.json_response(data)
async def app_factory():
app = web.Application()
ahsa.setup(app, [
ahsa.bind('sqlite+aiosqlite:///'),
])
await ahsa.init_db(app, metadata)
app.add_routes([web.get('/', main)])
return app
if __name__ == '__main__':
web.run_app(app_factory())
