Usage with Tornado (was: No DB associated to model)

Description

from tortoise.models import Model
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():
        await Tournament.create(name='Another Tournament')

        # Now search for a record
        tour = await Tournament.filter(name__contains='Another').first()
        print(tour.name)
    run_async(dps())

Research direction

The issue arises from misconfiguring the Tortoise ORM's `modules` parameter. Review the official documentation on model registration and the `Tortoise.init` call. Check if the model class is in the specified module and imported correctly. The comments in the issue may contain the resolution. For Tornado integration, ensure the async setup is compatible.
