why does flask logs only when app.debug = True?
flask, python
Solution
This is because flask considers `ERROR` as the default logging level if you do not set up log level, see: https://github.com/mitsuhiko/flask/blob/master/flask/logging.py#L28.
The solution is to add `app.logger.setLevel(logging.DEBUG)` before usage.
Problem
in main : ``` handler = RotatingFileHandler('/tmp/mylog') handler.setLevel(logging.DEBUG) app.logger.addHandler(handler) my_glob.logger = app.logger app.debug = True app.run(host='0.0.0.0', port=80) ``` in a 'url' : ``` import my_glob ... handling get request here: logger = my_glob.logger logger.info('this wont show unless app.debug=True is specified') logger.error('this always shows up') ``` if I do this, it works. If I remove app.debug = True, it doesn't work. But flask documentation says that app.debug is on local environments/debugging, not on production. So what should I use to enable logging on info/debug levels ?
