Django logger is mixing between levels: error and info

Question

i'm trying to add logging to my django project here's my logger configuration:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'standard': {
            'format': '%(asctime)s [%(levelname)s] %(name)s: %(message)s',
        },
    },
    'handlers': {
        'default': {
            'class': 'logging.FileHandler',
            'filename': os.path.join(*[BASE_DIR, 'logfiles', 'debug.log']),
            'formatter': 'standard',
        },
        'apps_errors': {
            'level': 'ERROR',
            'class': 'logging.FileHandler',
            'filename': os.path.join(*[BASE_DIR, 'logfiles', 'apps_errors.log']),
            'formatter': 'standard',
        },
        'dev_logger': {
            'level': 'INFO',
            'class': 'logging.FileHandler',
            'filename': os.path.join(*[BASE_DIR, 'logfiles', 'apps_logs.log']),
            'formatter': 'standard',
        },
    },
    'loggers': {
        '': {
            'handlers': ['default'],
            'level': 'DEBUG',
            'propagate': False,
        },
        'gui': {
            'handlers': ['dev_logger', 'apps_errors'],
            'propagate': True,
        },
        'crawler': {
            'handlers': ['dev_logger', 'apps_errors'],
            'propagate': True,
        },
    },
}

As you can see, I want to log everything to debug.log
and log errors on apps (crawler and gui) to apps_errors.log
and log info on apps (crawler and gui) to apps_logs.log

debug.log and apps_errors.log are working normally, everything is being logged to debug.log and only errors in my 2 apps, are being logged to apps_errors.log, but when it comes to apps_logs.log i keep getting both errors and info when it should be only info

by the way when i want to log something i'm doing

import logging
logger = logging.getLogger(__name__)

for info i'm doing : logging.info(my_info)

for errors i'm doing: logging.exception(my_exception) i also tried logging.error(my_exception)

PS:
i have tried defining two loggers, one for each handler, but doing that logs only errors using the errors logger/handler, the info one doesn't work

'gui': {
        'handlers': ['dev_logger'],
        'level': 'INFO',
        'propagate': True,
},
'gui': {
        'handlers': ['apps_errors'],
        'level': 'ERROR',
        'propagate': True,

If for some reason you only want INFO messages to show up in a handler's output, but nothing of higher severity, you would need to attach a filter to that handler. This is not a common requirement - though it's common to isolate errors and greater in logs, it's not common to isolate only INFO messages. Using a filter should work:

import logging

class InfoFilter(logging.Filter):
    def filter(self, record):
        return record.level == logging.INFO

and then assign that filter to your handler dev_logger. Not sure why you've called it dev_logger - perhaps you need to review your understanding of loggers and handlers. The top of the advanced tutorial gives a summary.
