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.

Defining onchange with the compute method

In the last two recipes, we have seen how to define and call the onchange method. We have also seen its limitation, which is that it can be invoked automatically only from the user interface. As a solution to this problem, Odoo v13 introduced a new way to define onchange behavior. In this recipe, we will see how you can use the compute method to produce behavior like the onchange method's.

Getting ready

For this recipe, we will use the my_library module from the previous recipe. We will replace the onchange method of library.return.wizard with the compute method.

How to do it...

Follow these steps to modify the onchange method with the compute method:

  1. Replace api.onchange in the onchange_member() method with compute like this:
        def onchange_member(self):
  2. Add the compute parameter...
