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

Wed Mar 27 00:56:13 UTC 2013

Hi Ryan,

AFAIK, there're two ways to do what you want. You could create a new Tag by
using the model directly and adding it to the package you want, as in:

    my_tag = model.Tag('my-tag')
    package.add_tag(my_tag)
    package.save()

Or you could simply do:

    package.add_tag_by_name('my-new-tag')

This will create a free tag with that name, if one doesn't exist yet.

Does this solve your problem?

Cheers,
Vítor Baptista.
