Product, Cart, Customer, Delivery, Payment, Order - what are the relationships between models in the Django project (online store)?

Question

Django

I made such relationships in models:
Product - many to many (Cart)
Customer - one to many (Order)
Delivery - one to one (Order)
Cart - one to one (Order)
Payment - one to one (Order)
1) What did it right, what's wrong?
2) What are the typical connections between these models?

Answer 1

Invent a virtual store for yourself Invent
the rules for how it works
Implement
Then change everything
There is no right or wrong option - the business sets the rules, not the developer

Answer 2

The easiest way is to take a ready-made Django store module as an example and see how everything is arranged inside. There are tons of django stores for you to choose from.
As for your data schema, I would correct it like this:

Товар - не связан с корзиной.
ЭлементКорзины - имеет внешние ключи к Товар и Заказ.
Заказ - содержит поля АдресДоставки (заполнятся клиентом) и ДоставкаВыполнена (булево поле или дата).
Корзина (как таблица БД) - не нужна.
Доставка (как таблица БД) - не нужна.
