Local application imports

Logging

rslogger = logging.getLogger("runestone")
rslogger.setLevel(logging.DEBUG)

handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter(
    "%(levelname)s - %(asctime)s - %(funcName)s - %(message)s"
)
handler.setFormatter(formatter)
rslogger.addHandler(handler)
 

To turn on debugging for FastAPI and the database package:

from fastapi.logger import logger
import logging
logger.setLevel(logging.DEBUG)

Otherwise, FastAPI logs at the default level. There is good info here on setting up logging. There is also good info on hooking into the gunicorn logging system when you deploy here.
