[ckan-dev] production deployment

Tue May 31 12:37:11 UTC 2011

A suggestion, change your wsgi boot file to import ckanext as per this snippet

...
execfile(activate_this, dict(__file__=activate_this))
# this is werid but without importing ckanext first import of
paste.deploy will fail
import ckanext
from paste.deploy import loadapp
...

I don't know why this helps but it seems to be useful for the plugins.
Also how are you running your production? Apache + modwsgi? We've
occasionally found problems running apache + modwsgi in daemon mode
with certain plugins (you have datapreview loaded i see).
