Django Model Inheritance - Abstract Models and Multi-Table Inheritance

[@tarikr5853]

As a Merise user, this gives an answer to how is implemented inheritance of entities that is modeled at the conceptual level of a database. thank you to you and the django project.

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!

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

[@bugbytes3923]

Thanks for commenting. Yes, you may have multiple different types of products, each with their own fields. But there may be a common set of fields that you can define on a base class (this could be an abstract model, or you could go with the multi-table inheritance approach). For example, all products would have a "price", so it makes sense to use this on a base class. But certain products may have different, specific fields. A clothing product may have fields such as "size", whereas a food/drink product may have fields such as "calories". These would belong in the subclasses. I hope that makes sense!

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.

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.
