[ckan-dev] Group search via API (v2)

Wed May 18 09:32:46 UTC 2011

Hi David,

thanks for your reply - I'll move it over  to the dev list now.

I followed your steps using a new DB and the test data and get the
correct results for those groups, too.

But when I create a new groups and add some of the packages to them (via
the web interface), I get empty result sets again through the API.

The permissions look fine, they are the same as for the existing groups:

User visitor ->  is reader on ->  Group tilo

reader              read-site, read-user, create-user, read

The web interface also displays the group's packages when I'm logged
out, but the API returns

$ curl http://localhost:5000/api/search/package?groups=tilo
{"count": 0, "results": []}

It seems there's something missing still, although the groups look quite
the same?

Best regards,

Tilo
