So I've tried going back to Django 1.7 but changing the app configuration
to use the AppConfig class and I've hit upon the same issue.
It would seem that part of the key is the fact that when the system hits
this line:
/home/osinski/Projects/feastly/apps/account/models.py in <module>()
11
12 from ipdb import set_trace; set_trace()
---> 13 from apps.common.models import CommonInfo
14 from feastly.paths import get_path
ImportError: No module named common.models
It would appear as though the "common" module hasn't loaded in apps yet.
Some posts on previous versions of Django have advised that the 'apps'
subdirectory should be included in the system path; we have never done this
before and thus far things have worked well, however I don't know if this
was suppored behavior. The negative to doing that is that I'd have to
rename all the imports from 'apps.X' to 'X'.
Does Django support apps that reside in submodules or have I been depending
on broken behavior?
