Overview of this book

With its latest iteration, the powerful Odoo framework released a wide variety of features for rapid application development. This updated Odoo development cookbook will help you explore the new features in Odoo 14 and learn how to use them to develop Odoo applications from scratch. You'll learn about the new website concepts in Odoo 14 and get a glimpse of Odoo's new web-client framework, the Odoo Web Library (OWL). Once you've completed the installation, you'll begin to explore the Odoo framework with real-world examples. You'll then create a new Odoo module from the ground up and progress to advanced framework concepts. You'll also learn how to modify existing applications, including Point of Sale (POS) applications. This book isn't just limited to backend development; you'll discover advanced JavaScript recipes for creating new views and widgets. As you progress, you'll learn about website development and become a quality Odoo developer by studying performance optimization, debugging, and automated testing. Finally, you'll delve into advanced concepts such as multi-website, In-App Purchasing (IAP),, the IoT Box, and security. By the end of the book, you'll have all the knowledge you need to build impressive Odoo applications and you'll be well versed in development best practices that will come in handy when working with the Odoo framework.

Adding models

Models define the data structures that will be used by our business applications. This recipe shows you how to add a basic model to a module.

In our example, we want to manage books for a library. To do this, we need to create a model to represent books. Each book will have a name and a list of authors.

Getting ready

We should have a module to work with. If you followed the first recipe in this chapter, Creating and installing a new add-on module, you will have an empty module called my_library. We will use that for our explanation.

How to do it...

To add a new Model, we need to add a Python file describing it and then to upgrade the add-on module (or install it, if this was not already done). The paths that are used are relative to our add-on module's location (for example, ~/odoo-dev/local-addons/my_library/):

  1. Add a Python file to the models/ module with the following code:
