[ckan-dev] Create free-form tag programmatically?

Tue Mar 26 23:34:00 UTC 2013

I'm trying to figure out how to add free-form (vocabulary-free) tags to a package programmatically, and I'm finding the documentation a little confusing.

http://docs.ckan.org/en/latest/ckan.logic.action.create.html#ckan.logic.action.create.package_create says I can add tags and "see tag_create() for the format of tag dictionaries"
http://docs.ckan.org/en/latest/ckan.logic.action.create.html#ckan.logic.action.create.tag_create says "To create a new free tag simply add the tag to a package, e.g. using the package_update function"
http://docs.ckan.org/en/latest/ckan.logic.action.update.html#ckan.logic.action.update.package_update doesn't really specify how to use it, so I tried:

package_update({"id": "my-package-id", "tags": [ "some", "free", "tags"]})

However that complains that it wants tags in dictionary format, as I would use for specifying tags that are part of a vocabulary. How do I specify a free tag?

Also, what is the best way to access the tags once I have them entered? I ran into a situation where my_package.package_tags contained a tag, but my_package.get_tags() returned an empty list?

Thanks so much!!
