Question

我正在设置SQLAlchemy日志记录，因此只记录特定类型的delete语句：

class DeleteFilter(logging.Filter):
    def filter(self, record):
        return 'DELETE FROM cr_pending_config WHERE cr_pending_config.id' in record.getMessage()

logger = logging.getLogger('sqlalchemy.engine')
logger.setLevel(logging.INFO)
logger.addFilter(DeleteFilter())

# create a file handler
handler = logging.FileHandler('sql_log.log')
handler.setLevel(logging.INFO)
handler.addFilter(DeleteFilter())

# create a logging format
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)

# add the handlers to the logger
logger.addHandler(handler)

问题是，在我的日志文件中，我看到了：

2017-11-07 20:34:44,196 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s
2017-11-07 20:40:37,169 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s
2017-11-07 20:41:21,704 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s
2017-11-07 20:41:21,858 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s
2017-11-07 20:41:21,987 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s
2017-11-07 20:41:44,658 - sqlalchemy.engine.base.Engine - INFO - DELETE FROM cr_pending_config WHERE cr_pending_config.id = %s

即，未记录实际ID。为什么???

sqlalchemy日志记录不显示参数值
