I have an abstract model called CharIDModel in
myproject/utils/__init__.py. If I import it as "from utils import
CharIDModel" and inherit from it, makemigrations crashes with:
{{{

Comment:
Based on the traceback, it looks like you're using Django 1.7. In Django
1.8 it looks like that `IndexError` is caught and you should get an error
message like 'Unable to detect the app label for model "%s." Ensure that
its module, "%s", is located inside an installed app.'" You might try
adding an explicit `Meta.app_label` to your abstract model. Feel free to
reopen if you continue to suspect a bug and can provide a sample project
running Django 1.8, as 1.7 is only receiving security updates at this
time. Thanks!
