[Flask] Logging from non-flask objects

[Scott Werner]

Expanding on Ziirish's reply, I do the following:

import logging


class MyObject(object):

    def __init__(self, logger=None):

        self.logger = logger or logging.getLogger(__name__)

    def hello(self):

        self.logger.info('hi')


my = MyObject(logger=current_app.logger)
