Technical requirements
The code in this chapter is based on the code created in Chapter 3, Your First Odoo Application. The necessary code can be found in the ch03/ directory of the Git repository at https://github.com/PacktPublishing/Odoo-12-Development-Essentials-Fourth-Edition.
You should have it in your addons path and install the library_app module. The code examples will assume that the Odoo database to work with is 12-library, to be consistent with the installation instructions given in Chapter 2, Preparing the Development Environment.
The code in this chapter can be found on the same repository, in the ch09/ directory.
