I tried that, but it doesn't work.
Here's the piece of relevant code on settings.py
```python
LOG_FILE = PROJECT_DIR.child('logs', 'frespo.log')

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'standard': {
            'format': '%(asctime)s [%(levelname)s] %(name)s: %(message)s'
        },
    },
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'handlers': {
        'null': {
            'level':'DEBUG',
            'class':'django.utils.log.NullHandler',
        },
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        },
        'default': {
            'level':'DEBUG',
            'class':'logging.handlers.RotatingFileHandler',
            'filename': LOG_FILE,
            'maxBytes': 1024*1024*5, # 5 MB
            'backupCount': 5,
            'formatter':'standard',
        },
#... etc etc
```

then on env_settings.py I override the `LOG_FILE` variable, but this override is ignored - which makes sense, because the `LOGGING` is alrady configured.

No worries. I'll redefine the entire `LOGGING` dictionary on the env_settings. That's ok.
