I have added a custom loggin to my django project but it isn't working

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.")

the issue with your django logging configuration is likely due to django's default loggers are not properly configured to use your custom logging setup.

By default django uses its own loggers (e.g., django, django.request, etc.) and unless you explicitly configure these loggers to use your custom handlers they won't write to your specified log files.

rewrite them like this:

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',
        },

            'level': 'INFO',
