Hello, Sorry, I forgot that relative imports don’t work in standalone scripts, just modules. In this case, yes, you should go on with the original import line of yours, and modify the loading path. However, if you want to use your models outside of Django, that is 1) pretty much unsupported and 2) you must initialize your app (I hope someone can point to a document that shows how; I have no knowledge on this. I guess you will have to mess around with django.apps).
Well, all this is unless you create a django-admin command, which will do all this for you (the application/model initialization). When you invoke a command like “python manage.py migrate”, all your apps in INSTALLED_APPS get loaded, and thus, initialized. After that, in the command’s handle() method, you can do whatever you want. Also another thing you win is that the maintenance scripts will be actually integrated into your application and you can even write tests for them.
