Django logging is empty

Question

I'm having a problem, what on Earth just happened after I added a formatter to the LOGGING configuration? The logging file is empty.

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'verbose': {
            'format': '{asctime} [{module}]:: {message}',
            'style': '{',
        },
        'simple': {
            'format': '{levelname} {message}',
            'style': '{',
        },
    },
    'handlers': {
        'console':{
            'level': 'INFO',
            'class': 'logging.StreamHandler',
            'formatter': 'verbose'
        },
        'file.DEBUG': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'logs/debug.log',
            'maxBytes' : 1024*1024*10,
            'backupCount': 10,
            'formatter':'verbose'
        },
        'file.INFO': {
            'level': 'INFO',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'logs/info.log',
            'maxBytes' : 1024*1024*10,
            'formatter':'verbose'
        },
        'file.ERROR': {
            'level': 'INFO',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': 'logs/error.log',
            'maxBytes' : 1024*1024*10,
            'backupCount': 10,
            'formatter':'verbose'
        },
    },
    'loggers': {
        'django.request': {
            'handlers': ['file.DEBUG'],
            'level': 'DEBUG',
            'propagate': True,
        },
        'django': {
            'handlers': ['file.INFO'],
            'level': 'INFO',
            'propagate': True,
        },
        'django': {
            'handlers': ['file.ERROR'],
            'level': 'ERROR',
            'propagate': True,
        },
    },
}

Now all the outputed debug files are empty except for the error file which I tested on the view with this code

import logging
logger = logging.getLogger('django')

logger.info('tests')
logger.error('tests')
logger.debug('tests')
logger.debug('tests')
logger.error('tests')
logger.info('tests')

Only the error is being logged on the file, why is this happening? I'm using the new version of django which is 2.2

Update Don't know what just I did but its working now This is my new LOGGING setting

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
            'verbose': {
                'format': '{levelname} {asctime} [{module}]:: {message}',
                'style': '{',
            },
            'simple': {
                'format': '{levelname} {message}',
                'style': '{',
            },
        },
    'handlers': {
        'file_debug': {
            'level': 'DEBUG', 
            'class': 'logging.FileHandler',
            'filename': 'logs/debug.log',
            'formatter':'verbose'
        },
        'file_error': {
            'level': 'ERROR',
            'class': 'logging.FileHandler',
            'filename': 'logs/error.log',
            'formatter':'verbose'
        },
        'file_info': {
            'level': 'INFO',
            'class': 'logging.FileHandler',
            'filename': 'logs/info.log',
            'formatter':'verbose'
        },
    },
    'loggers': {
        'django.server': {
            'handlers': ['file_debug'], 
            'level': 'DEBUG',
            'propagate': True, 
        },
        'django': {
            'handlers': ['file_error'], 
            'level': 'ERROR',
            'propagate': True, 
        },
        'django': {
            'handlers': ['file_info'], 
            'level': 'INFO',
            'propagate': True, 
        },
    },
}

Because you did not configure the LOGGING. In your settings you have two entries for django, and django is writing logs based on the last entry. Instead of that, you should have put the configuration like this:

'loggers': {
        'django.request': {
            'handlers': ['file.DEBUG'],
            'level': 'DEBUG',
            'propagate': True,
        },
        'django': {
            'handlers': ['file.INFO', 'file.ERROR'],  # <-- Here
            'level': 'INFO',
            'propagate': True,
        }
}

Please see the last example of the examples section of documentation.
