Make 1 app called core or common of whatever and replace models.py with models/<namespace_or_domain>.py and import those into models/__init__.py
Everyone jumps into apps with foreign keys across app boundaries and it makes a mess of things from the start that doesnt buy you anything.
1 app. 1 set of migrations. Turn models, views, etc into a package instead of the single file module.
Its the one thing I wish the docs would prescribe and demonstrate for new project advice. .
