Question

Is it possible to register a model in django-tagging not in tagging app, nor in my app?

The standard way is to edit apps/myapp/models.py this way:

from apps import tagging
tagging.register(MyModel)

I want to keep both applications without changes, for example, to be able to pull new versions and just replace them. So I tried putting this into project settings.py, in the end, but of course this fails.

from apps.myapp.models import MyModel
from apps import tagging
tagging.register(MyModel)

(This fails when importing MyModel.)

Any other way?

You can’t do that in settings.py, as the models haven’t been set up yet. One possibility is to do it in urls.py – admin.autodiscover is already there, so this might be a good place for the call to tagging.register as well.

There has been quite a lot of discussion in the django-developers group about the correct place for this sort of thing, but as yet no firm policy has been reached.
