Comment (by mkibbel):
I've been having a similar problem recently with one of my projects. The
AttributeError gets raised inside the call to admin.autodiscover() in my
urls.py, similar to bugs described in #8569. Due to model
interdependencies, I have to to use lazy model referencing with quoted
strings for some of the FK and M2M relationships in my project.
I never ran into this AttributeError until I turned DEBUG off. After
reading through these tickets and pouring through some of the Django
source code, I came up with a simple workaround for my particular problem.
Just add this to urls.py before calling admin.autodiscover():
{{{
from django.db.models.loading import cache as model_cache
if not model_cache.loaded:
model_cache.get_models()
}}}
My reasoning for this is explained briefly in the next comment.
