Are you *really* sure you want to do this? Monkey-patching running code, adding class attributes and inserting database columns on the fly to a production system isn't something recommended in textbooks. Try describing your situation a bit. Maybe you could use a key-value approach and m2m relations instead? If you *really* want to do it, and you want to edit models.py, then you should schedule an external task that appends the column to models.py (and commits the change to your VCS, adds tests, ...) and deploys the new code on your server. Another possibility is that you avoid editing models.py by creating the new database column manually using raw SQL, so Django doesn't know about it. Then override __getattr__ on the model so my_obj.extra_col_123 circumvents the ORM and fetches data by other means, or simply issue raw SQL when you need to access 'extra_col_123' in your code.
