Hi.

I just successfully integrated Sentry in one of my projects for evaluation purposes and I am delighted! This tool is great. So I wanted to integrate it into another project of mine that is running with Django 1.3. Unfortunately it does not seem to log. I am getting this error message when I run my project as Sentry client with the Django dev server:

No handlers could be found for logger "sentry.errors"

Any hints on what I am doing wrong and what I have to do to get this working?

The sentry.errors handler is where Sentry writes internal problems.
It's likely you have a configuration problem, but the easiest way to
diagnose that will be to configure that logger:

import logging
logger = logging.getLogger('sentry.errors')
logger.setLevel(logging.INFO)
logger.addHandler(logging.StreamHandler())

I should add a ticket to make sentry.errors auto log to stderr as a
default behavior (unless you turn off some flag), since this seems to
come up every so often.

I used this configuration and here is the result and the real problem. I guess it is a problem in my project but non the less it might be useful for you:
