python Django日志记录设置

Posted 2021-05-09

# Logging settings for django projects, works with django 1.5+
# If DEBUG=True, all logs (including django logs) will be
# written to console and to debug_file.
# If DEBUG=False, logs with level INFO or higher will be
# saved to production_file.
# Logging usage:

# import logging
# logger = logging.getLogger(__name__)
# logger.info("Log this message")
