Learning project – improving the Library app

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

We will add a category hierarchy, to use for book categorization, with the following:

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

The book model already has fields for essential information, and we will add a few more to showcase the several data types available in Odoo.

We will also add some constraints to the Books Model:

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