raven - sentry + django = No servers configured, and sentry not installed. Cannot send message - sentry

Question

I have a sentry server that works ok.
raven test <dnstoserver> -> Sending a test message... success!
I have a dev machine with django 1.3 and raven 1.93.
In the django project I have this:
setting.py:
SENTRY_KEY=<secretkey>
SENTRY_DNS=<dnstoserver>
INSTALLED_APPS = (
'bar',
'foo',
'raven.contrib.django',
)
LOGGING = {
'version': 1,
'disable_existing_loggers': True,
'root': {
'level': 'WARNING',
'handlers': ['sentry'],
},
'formatters': {
'verbose': {
'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'
},
},
'handlers': {
'sentry': {
'level': 'ERROR',
'class': 'raven.contrib.django.handlers.SentryHandler',
},
'console': {
'level': 'DEBUG',
'class': 'logging.StreamHandler',
'formatter': 'verbose'
}
},
'loggers': {
'django.db.backends': {
'level': 'ERROR',
'handlers': ['console'],
'propagate': False,
},
'raven': {
'level': 'DEBUG',
'handlers': ['console', 'sentry'],
'propagate': False,
},
},
}
Mind the absence of 'sentry' in the installed_apps. This is intentionally, since sentry is the server and should not be on a client!
views.py (in a view):
import logging
logger = logging.getLogger("raven")
logger.error("test")
When I run the view I get on the console:
No servers configured, and sentry not installed. Cannot send message
Why, and how to fix?

Answer 1

Were you really setting SENTRY_DNS or SENTRY_DSN?
When you set SENTRY_DSN the instantiation of the major config variables happens automatically (including SENTRY_SERVERS, SENTRY_PUBLIC_KEY, SENTRY_SECRET_KEY, and SENTRY_PROJECT)

Answer 2

The problem was in the construction of the raven DjangoClient. It did not get passed any servers, and couldn't find sentry config to steal that config from.
I added in the settings.py:
SENTRY_SERVERS=<dnstoserver>
Console now outputs this every time raven is called:
INFO 2012-06-21 05:33:19,831 base 4323 140735075462336 Configuring Raven for host: <dnstoserver>
But it works like a charm! Messages in sentry...
BTW. for all the undocumented settings take a look in raven.contrib.django.models.get_client()

Answer 3

I suggest to use:
SENTRY_DSN = 'http://user:password#<domain>:<port>/<project_id>'
And in APPS_INSTALLED add:
'raven.contrib.django.raven_compat'
Also take a look at this guide:
