[ckan-dev] ckanext-harvest: "There are no new harvesting jobs"

Mon Jul 20 15:23:06 UTC 2015

Hi,

I have a problem setting up ckanext-harvest for production. I’m following the steps explained in https://github.com/ckan/ckanext-harvest/blob/master/README.rst#setting-up-the-harvesters-on-a-production-server <https://github.com/ckan/ckanext-harvest/blob/master/README.rst#setting-up-the-harvesters-on-a-production-server>, which works great at first. However, after the first time the harvester is run, I get an error message saying "Exception: There are no new harvesting jobs” each time the harvester is run again via cron. It seems I have to first create a new harvesting job via command line or Web UI. Is this intended behaviour? Or am I missing something? Could someone point me in the right direction?

Exception: There are no new harvesting jobs
------------

I should add that I’m running an old version of the ckanext-harvest (@0609262731) and an old version of CKAN (1.8.2). I don’t think that’s the reason, though.

Cheers,
Knud
