[ckan-dev] Adding a tag to a package

Thu Aug 13 13:19:20 UTC 2015

Hello,
If you are using CKAN 2.2 read carefully
http://docs.ckan.org/en/ckan-2.3/api/index.html#ckan.logic.action.update.package_update
(It is recommended to call ckan.logic.action.get.package_show()
<http://docs.ckan.org/en/ckan-2.3/api/index.html#ckan.logic.action.get.package_show>,
make the desired changes to the result, and then call package_update() with
it.)
If you have 2.3 I recommend to use:
http://docs.ckan.org/en/ckan-2.3/api/index.html#ckan.logic.action.patch.package_patch
which i think is doing what you need.
I didn't test it, but I found it useful :)
