This is what I need for my project, I've been figuring out decent ways to avoid duplication of model content to each and every content I make in my project. Thanks you!

An issue with Multiple Inheritance is that you can have a performance hiy if your database is too large, because in has to make joins for every query.

It would be cool if you could make a video about using composition in Django 💪

I used field created_at and updated_at in CommonField class and inherited but how do i make sure that the created_at and updated_at columns are at last of the table because when i inherited it, it comes at first of the table.

Hi Bugbytes, thanks for this new video. Can this model inheritance be used in product variation of an eccommerce? If yes, how?
