django-deferred-filelogger

This package provides a new logging handler that defers evaluation of the filepath until a message is emitted. It uses a setting LOG_ROOT as the folder for the log files. This is useful when you don't know the exact location of your log files when the LOGGING setting is defined - this can be the case if you have a environment specific settings file which gets imported after your core settings.

Usage

In your main settings file, configure your handlers with a filename

LOGGING = {
    ...
    'handlers': {
        'error_file': {
            'level': 'INFO',
            'class': 'deferred_filelogger.DeferredFilehandler',
            'filename': 'errors.log',
        }
    },
    'loggers': {
        'django.request': {
            'handlers': ['error_file', 'mail_admins'],
            'level': 'ERROR',
            'propagate': False
        }
    }
}

then in your environmental overrides (eg settings_local.py), specify a LOG_ROOT folder. For instance, in your test environment you might specify

LOG_ROOT = '/var/www/client/project/logs/test'

which would cause your Django errors to be logged to /var/www/client/project/logs/test/errors.log.
