Ich versuche, meinen eigenen Protokoll-Handler zu erstellen, um in DB-Modellen zu protokollieren, wodurch die Protokollierung erweitert wird

import logging
from logging import Handler
from logger.models import SearchLog

class DBHandler(Handler,object):
    model = None
    def __init__(self, model):
        super(DBHandler, self).__init__()
        mod = __import__(model)
        components = name.split('.')
        for comp in components[1:]:
            mod = getattr(mod, comp)
        self.model = mod

    def emit(self,record):
        log_entry = self.model(level=record.levelname, message=record.msg)
        log_entry.save()

und das ist die log config:

'db_search_log':{
    'level': 'INFO',
    'class': 'db_logger.handlers.DBHandler',
    'model': 'db_logger.models.SearchLog',
    'formatter': 'verbose',
     }

Ich erhalte jedoch den folgenden Fehler (siehe Stacktrace):

Dank @istruble darauf hingewiesen, dass dies auf zirkuläre Importe von Einstellungen zurückzuführen ist, wie kann ich es vermeiden und trotzdem in die Datenbankmodelle einloggen?
