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?

I am sure: I don't want it. I guess you have read my post too fast.

> 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.

Yes, this would be a solution.

Thank you for your feedback.
