Really disable logger logging in Flask

flask.py

# I have my own logging setup and had a hard time disabling console output in Flask. 

    app.logger.disabled = True
    log = logging.getLogger('werkzeug')
    log.disabled = True
    
# New, 2022 Method:

    logging.getLogger('werkzeug').disabled = True

Nice!

Great, used this today. Thanks!

What is 'cf'?

import logging
app.logger.disabled = True
log = logging.getLogger('werkzeug')
log.disabled = True

It dosn't work fo me

It doesn't work for me either.

This was used back in maybe 2012 and published in 2014. Sorry to any users who are having issues w. it in 2021+ no longer working. If anybody provides an update, I can update the gist. Thanks.

This works for me :)

i just add the line "logging.getLogger('werkzeug').disabled = True" and worked

Thank you, it worked

For the record, this only disables the logging statements. If you want to disable the console warnings too, you have to monkeypatch the function that does that (see: cs01/gdbgui#425):

import flask.cli    
flask.cli.show_server_banner = lambda *args: None

The old hack (os.environ["WERKZEUG_RUN_MAIN"] = "true") doesn't work in werkzeug >=2.1.0.

@mconigliaro Man! your code works well! Thanks :)

If using flask-socketio:

logging.getLogger("werkzeug").disabled = True
logging.getLogger("geventwebsocket.handler").disabled = True

Really nice! I'm using Flask 2.2.3, it works.

Thank you!
This worked perfectly for me.

pasted right below the instantiation line
app = Flask(name)
logging.getLogger('werkzeug').disabled = True
