Create a models.py and import there your models from wherever they are. This should do the trick.

Yeah, or another way of splitting up huge models files is to convert models from a module to a package by making a directory models and adding models/__init__.py, models/foo_models.py, models/bar_models.py then doing

from .foo_models import *

from .bar_models import *

in your __init__.py

Separating models like this is a hint that you may need another app. It has happened numerous times with me now that my models.py gets large and unwieldy, I spends a hour breaking it all out and then I realise my one big God app needs to be 3 smaller ones.

Totally agreed.
