Description

from tortoise.fields import *

class Tournament(Model):
    id = IntField(pk=True)
    name = TextField()

if __name__ == "__main__":
    from tortoise import Tortoise, run_async


    async def init():
        # Here we create a SQLite DB using file "db.sqlite3"
        #  also specify the app name of "models"
        #  which contain models from "app.models"
        await Tortoise.init(
            db_url='sqlite://otc.db',
            modules={'models': ['model']} # 传入模块名称，本模块名为 model
        )
        # Generate the schema
        await Tortoise.generate_schemas()


    run_async(init())

    async def dps():

Contributor guide

Research direction

Ensure that Tortoise.init() is called within an async context and that the event loop remains active. Wrap all async calls in a single async main function and use run async() once. For Tornado integration, initialize Tortoise inside the Tornado application's startup handler using IOLoop.current().
