When building a Django application, how can I properly design and manage relationships between different database tables (models) — like one-to-many, many-to-many, or nested relationships — so that my code stays clean and my app runs efficiently?
This isn’t really a Django-specific question. The Django ORM is a wrapper around the SQL being generated, and a mapping of the table data being retrieved to a set of Python classes. As a result, your database design would be the same as it would for any other relational-db-based application. Using Django should not alter how you design your database.
