记录MongoEngine生成的原始查询

Question

是否有一个更简单的方法来编写中间件或任何其他方式，我可以记录所有的查询。

Answer 1

我在我的项目中使用了pymongo.monitoring。

import logging
from pymongo import monitoring

class CommandLogger(monitoring.CommandListener):

    def started(self, event):
        log.debug("Command {0.command}".format(event))
        logging.info("Command {0.command_name} with request id "
                 "{0.request_id} started on server "
                 "{0.connection_id}".format(event))

    def succeeded(self, event):
        logging.info("Command {0.command_name} with request id "
                 "{0.request_id} on server {0.connection_id} "
                 "succeeded in {0.duration_micros} "
                 "microseconds".format(event))

    def failed(self, event):
        logging.info("Command {0.command_name} with request id "
                 "{0.request_id} on server {0.connection_id} "
                 "failed in {0.duration_micros} "
                 "microseconds".format(event))

monitoring.register(CommandLogger())
