Learning project – improving the Library app

In Chapter 3, Your First Odoo Application, we created the library_app add-on module and implemented the simple library.book model to represent a book catalog. In this chapter, we will revisit that module to enrich the data that we can store for each book.

• Name: The category title
• Parent: The parent category that it belongs to
• Subcategories: The categories that have this one as the parent
• Featured book or author: A selected book or author that represents this category

A few more fields will be added to showcase the different data types available for Odoo fields. We will also use model constraints to implement a few validations on the Books model:

• The title and publication date should be unique.
• ISBNs entered should be valid.
