I have added this code to my settings.py, but it's not working (It's not logging errors warnings and ...). Django default logging works perfectly fine, debug is True in my settings and I've created logs folder manually.

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'file_logging': {
            'format': '{levelname} / {levelno} - {asctime} --- {pathname} in {lineno} --- {process:d} {thread:d} -- {message}',
            'style': '{'
        },
        'email_logging': {
            'format': '{levelname} at {asctime} --- {pathname} in {lineno} -- {message}',
            'style': '{'
        },
    },
    'filters': {
        'debug_true_required': {
            '()': 'django.utils.log.RequireDebugTrue'
        }
    },
    'handlers': {
        'full_handler': {
            'level': 'INFO',
            'class': 'logging.FileHandler',
            'filename': 'logs/full.log',
            'formatter': 'file_logging',
        },
        'critical_handler': {
            'level': 'CRITICAL',
            'class': 'logging.FileHandler',
            'filename': 'logs/critical.log',
            'formatter': 'file_logging',
        },
        'error_handler': {
            'level': 'ERROR',
            'filters': ['debug_true_required',],
            'class': 'logging.FileHandler',
            'filename': 'logs/error.log',
            'formatter': 'file_logging',
        },
        'critical_email_handler': {
            'level': 'CRITICAL',
            'class': 'django.utils.log.AdminEmailHandler',
            'formatter': 'email_logging',
        },
        'error_email_handler': {
            'level': 'ERROR',
            'filters': ['debug_true_required',],
            'class': 'django.utils.log.AdminEmailHandler',
            'formatter': 'email_logging',
        },
    },
    'loggers': {
        'file_logger': {
            'handlers': ['full_handler', 'critical_handler', 'error_handler'],
            'level': 'INFO',
            'propagate': True
        },
        'email_logger': {
            'handlers': ['critical_email_handler', 'error_email_handler'],
            'level': 'ERROR',
            'propagate': True
        },
    }
}

I tried recreating logs folder again, but it didn't work. I then tried to change 'propagate': False to True but it didn't work again. I also tried logging manualy with this code, which works perfectly fine, and the logs saved correctly in my logging files.

logger = logging.getLogger('file_logger')
logger.info("This is a test log message.")

logger = logging.getLogger('email_logger')
logger.critical("This is a test critical message.")
