[ckan-dev] Using sentry with ckan

Mon Feb 17 13:46:36 UTC 2014

Hello

Yes I have got sentry working with CKAN.  If you are running ckan
under apache with a wsgi file like:
https://github.com/ckan/ckan-packaging/blob/master/etc/ckan/default/apache.wsgi

You can add the following to the bottom of the file (obviously
changing the client uri):

from raven import Client
from raven.middleware import Sentry
client = Client('https://44e18489493144403f:4e7d36fe7c08e85ba065a@app.getsentry.com/18472',
name='mytestinstance')
application = Sentry(application, client=client)

from pylons.middleware import StatusCodeRedirect
#this is to make sure 404 are redirected to a page that looks nice,
normally done by setting full_stack = True
application  = StatusCodeRedirect(application , [400, 404, 500])

You also have to set the ckan config file to have

full_stack = false

This will stop the pylons error middlewhere catching these errors and
therefore all errors will get to sentry.

IMiddlewhere would work but it would not catch all possible errors as
its too close to the centre of the middlewhere stack.  i.e if
repoze.who for example went wrong it would not catch it.   The above
approach means that it catches everything as it is the outermost app.

Thanks

David
