This project is a Django REST Framework API for managing a collection of books and authors. It includes features like token-based authentication, filtering, searching, and ordering.

• Book and Author API Endpoints: Provides full CRUD (Create, Read, Update, Delete) functionality for books and authors.
• Token Authentication: Secures the API using djangorestframework.authtoken.
• Filtering: Allows filtering books by publication_year and author__name.
• Searching: Enables searching for books by title and author__name.
• Ordering: Supports ordering books by title and publication_year.
• Serialization: Uses ModelSerializer to handle the conversion of Book and Author models to and from JSON.
• Nested Serialization: The Author serializer includes a list of books written by the author.
