db_state = ContextVar("db_state", default=db_state_default.copy())


class PeeweeConnectionState(peewee._ConnectionState):
    def __init__(self, **kwargs):
        super().__setattr__("_state", db_state)
        super().__init__(**kwargs)

    def __setattr__(self, name, value):
        self._state.get()[name] = value

    def __getattr__(self, name):
        return self._state.get()[name]

So, we need to do some extra tricks to make it work as if it was just using `threading.local`. The `__init__`, `__setattr__`, and `__getattr__` implement all the required tricks for this to be used by Peewee without knowing that it is now compatible with FastAPI.
