AttributeError: 'NoneType' object has no attribute 'acquire'

I have this problem when switching schemas dynamically

def demo_conf_db_switch(db_base):
    def func_work(func):
        @functools.wraps(func)
        async def wrapper(*args, **kwargs):
            await Tortoise.init(db_base)
            await Tortoise.generate_schemas()
            data = await func(*args, **kwargs)
            await Tortoise.close_connections()
            return data
        return wrapper
    return func_work

db_base Is the link parameter I passed

There's this

But I do this

It can perfectly solve the switching mode, but I need to use SQL. Can I use tortoise statements

Start from the demo_conf_db_switch wrapper and the reported AttributeError involving acquire. Review how Tortoise.init, generate_schemas, and close_connections are used during dynamic schema or database switching. Done would require a confirmed explanation and a documented or tested way to perform the requested SQL-backed workflow, but no repository files or tests are named.
