logging.Handler を拡張する db モデルにログを記録する独自のログ ハンドラーを作成しようとしています。
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()
これはログ構成です:
'db_search_log':{
'level': 'INFO',
'class': 'db_logger.handlers.DBHandler',
'model': 'db_logger.models.SearchLog',
'formatter': 'verbose',
}
ただし、次のエラーが発生します。スタックトレースを参照してください。

@istruble のおかげで、これは設定の循環インポートが原因であると指摘されました。どうすればそれを回避し、データベース モデルにログを記録できますか?
