Re: log doesn't work

[Shu Lin]

I basically identified it is a paste parsing ini file problem since if I put below into code, things start working:

import logging

log = logging.getLogger(__name__)

log.setLevel(logging.INFO)

But, we can see, in the ini file, I have set log level at least to INFO level for every module.

What's the problem of ini file parsing? How to debug it?

Thanks a lot,

Hi,

The debug log doesn't work for dependent libraries suddenly. The log still works for the main project, in this case, it is "crossbow_py". But, not for sqlalchemy anymore. What's wrong with my configuration? Below is my development.ini.

Thanks a lot,

If you're having issues with log messages and levels etc, I highly recommend Brandon Rhodes' logging_tree module:

http://rhodesmill.org/brandon/2012/logging_tree/

Python's logging is a complex beast; there are talks on it at every PyCon I've been at.

Good luck!

Taavi,

The logging tree really helps on understanding of the log. Now, I know the logging is really a beast.

Thanks a lot,
