How to config flask app.logger from a configure file?

Question

Is there any way to config flask app.logger from a configure file, like:

logging.config.fileConfig('/path/to/logging.cfg')

or

logging.config.dictConfig(config_dict)

So i can use app.logger.info('some message') to log both in develop and product mode.

Answer 1

You need to call app.logger first and then logging.config.dictConfig(config_dict). The logger name should be the same in config_dict and in app.logger_name

Answer 2

Change logging on line 22 to app.logger - that will configure the logger for your current Flask app. Alternately, you can use the logging module's getLogger function and use app.logger_name to pull the correct logger.
