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), Odoo.sh, 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.

Reporting errors to the user

During method execution, it is sometimes necessary to abort processing because the action that's requested by the user isn't valid or an error condition has been met. This recipe shows you how to manage these cases by showing a helpful error message.

Getting ready

This recipe assumes that you have an instance ready, with the my_library add-on module available, as described in the previous recipe.

How to do it...

We will make a change to the change_state method from the previous recipe and display a helpful message when the user is trying to change the state that is not allowed by the is_allowed_transition method. Perform the following steps to get started:

  1. Add the following import at the beginning of the Python file:
    from odoo.exceptions import UserError
from odoo.tools.translate import _
  2. Modify the change_state method and raise a UserError exception from the else part:
    def change_state(self, new_state):
