Why is Django logging not working with Gunicorn?

Question

I have a django site with is behind a gunicorn server. Here are the logging settings for django -

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': '[%(asctime)s][%(levelname)s] %(message)s',
        },
    },
    'handlers': {
        'file': {
            'level': os.environ['DJANGO_LOGLEVEL'],
            'class': 'logging.FileHandler',
            'filename': '/mnt/storage/logs/django.log',
            'formatter': 'verbose',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': os.environ['DJANGO_LOGLEVEL'],
            'propagate': True,
        },
    },
}

Here is the command which starts gunicorn server -

gunicorn training_service.wsgi -b 0.0.0.0:8000 -w 4 --access-logfile /mnt/storage/logs/access.log --log-file /mnt/storage/logs/gunicorn.log --log-level $GUNICORN_LOGLEVEL

Now, my understanding is that both the logging frameworks should work completely independent of each other. But when I launch the django site by calling manage.py runserver logging works are expected from the django settings.

But when I launch the same thing using the gunicorn command both the logging format and the debug logs from django disappear. I am not sure what is wrong here because disable_existing_loggers is also set to false. And I don't know if there is any setting in gunicorn which should effect django's logging functionality.

The only difference is Debug is set to False when I run with gunicorn.

我遇到了同样的问题，在 view.py 中，我有以下行

import logging
logger = logging.getLogger("logger_name")

我打印了 logger.__dict__，结果发现 logger 已禁用=True 因此，在执行任何信息/调试/错误等操作之前，我将其更改为 False。

logger.disabled = False

然后它就像一个魅力
