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 features to a model using inheritance

One of the most important Odoo features is the ability of module add-ons to extend features that are defined in other module add-ons without having to edit the code of the original feature. This might be to add fields or methods, modify the existing fields, or extend the existing methods to perform additional logic.

According to the official documentation, Odoo provides three types of inheritance:

  • Class inheritance (extension)
  • Prototype inheritance
  • Delegation inheritance

We will see each one of these in a separate recipe. In this recipe we will see Class inheritance (extension). It is used to add new fields or methods to existing models.

We will extend the built-in partner model res.partner to add it to a computed field with the authored book count. This involves adding a field and a method to an existing model.

Getting ready

We will continue using the my_library add-on module from the previous recipe.
