tornado deploy django and the log repeat output - django

Question

In my project i deployed my django-project with tornado server, and my tornado main function is:
def main():
tornado.options.options.logging = None
tornado.options.parse_command_line()
os.environ['DJANGO_SETTINGS_MODULE'] = 'Zero.settings'
application = get_wsgi_application()
container = tornado.wsgi.WSGIContainer(application)
http_server = tornado.httpserver.HTTPServer(container, xheaders=True)
http_server.listen(tornado.options.options.port)
tornado.ioloop.IOLoop.current().start()
When i use tornado.options.options.logging = None to disabled tornado logging output, but it still output the log message in my console with twice, my django logging config is:
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'formatters': {
'standard': {
'format': '%(asctime)s [%(threadName)s] [%(name)s:%(funcName)s] [%(levelname)s]- %(message)s'}
},
'filters': {
},
'handlers': {
'error': {
'level': 'ERROR',
'class': 'logging.handlers.RotatingFileHandler',
'filename': os.path.join(BASE_DIR, 'log', 'error.log'),
'maxBytes': 1024*1024*5,
'backupCount': 5,
'formatter': 'standard',
},
'console':{
'level': 'INFO',
'class': 'logging.StreamHandler',
'formatter': 'standard'
},
},
'loggers': {
'django': {
'handlers': ['console'],
'level': 'INFO',
'propagate': True
},
}
}
The final result is:
2018-06-15 17:40:55,724 [MainThread] [base_views:get] [INFO]- get message correct
INFO:base_views:get message correct
so what can i do to solve this problem.
Thank U.

You've only configured the django logger, not the root logger. When Tornado sees that the root logger is not configured, it adds its own last-resort handler (using logging.basicConfig instead of tornado.log). Because of the way python loggers propagate, this results in any other loggers being duplicated.
When you use tornado.options.options.logging = None, you should make sure that you configure the root logger yourself, or configure all of your other handlers with propagate=False. In this case, move the loggers.django section of your config to a new root section:
'handlers': {...}
'root': {
'handlers': ['console'],
'level': 'INFO',
},
