[ckan-dev] Upgrading to 2.7.2 - error building search index

Tue Oct 17 15:07:29 UTC 2017

Hi List

Thanks for all the work going into new versions of CKAN.  I've just upgraded to 2.7.2 on Ubuntu 14.04.  I run the web application on one server and the database on another.  I have got almost everything working correctly again but there are a couple of issues I have.

My site (http://opendata.angus.gov.uk) is reading the customised theme and gets the list of organisations and groups but not the datasets.

I've tried to rebuild the search index and get the following error:

# paster search-index rebuild -c /etc/ckan/default/production.ini

2017-10-17 15:25:42,627 WARNI [ckan.lib.celery_app] ckan.lib.celery_app is deprecated, use ckan.lib.jobs instead.

Line 101 in search/index.py self.index_package(pkg_dict, defer_commit)

Line 256 in search/index.py pkg_dict['metadata_created'] += 'Z'

I can get to http://opendata.angus.gov.uk/stats/ and http://opendata.angus.gov.uk/report/ and from there I can see datasets and resources like http://opendata.angus.gov.uk/dataset/angus-council-conservation-areas and http://opendata.angus.gov.uk/dataset/angus-council-conservation-areas/resource/f2ce10ae-2571-4f27-8904-2304fc8efdd1 so it is reading the database and pulling out the correct information.

The other issue I have is logging in - I have a valid username / password  but I keep getting an error.  Are these credentials stored in the PostgreSQL database?  I upgraded the database with

# paster db upgrade -c /etc/ckan/default/production.ini

But got returned to the prompt after a few seconds with no indication of success or failure.

I also set the datastore permissions.

So, I guess my questions are 1) has my database been upgraded to work with 2.7.2 and 2) is that why my search index rebuild fails?

As an aside, the warning messages about Celery being deprecated and to use ckan.lib.jobs instead that keep popping up, are these for me or for extension developers?  Is the upgrade to 2.8.0 going to change the backend even more?

Thanks in advance for any pointers
