26023	Importing GenericForeignKey on Django 1.9	Chris Mitchell	nobody	"It appears it is not possible to import GenericForeignKey from outside a live Django project in 1.9.  To reproduce this error:


{{{
from django.conf import settings
settings.configure()
from django.contrib.contenttypes.fields import GenericForeignKey
}}}

Produces:

}}}

This seems to be occurring because ModelBase is attempting to get the app config, but the configuration step has not occurred. "	Bug	closed	contrib.contenttypes	1.9	Normal	invalid	generic foreign keys		Unreviewed	0	0	0	0	0	0
