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.

Extending write() and create()

The Extending the business logic defined in a model recipe from this chapter showed us how to extend methods that are defined on a model class. If you think about it, methods that are defined on the parent class of the model are also part of the model. This means that all the base methods that are defined on models.Model (actually, on models.BaseModel, which is the parent class of models.Model) are also available and can be extended.

This recipe shows you how to extend create() and write() to control access to some fields of the records.

Getting ready

We will extend the library example from the my_library add-on module in Chapter 3, Creating Odoo Add-On Modules.

Add a manager_remarks field to the library.book model. We only want members of the Library Managers group to be able to write to that field:

from odoo import models, api, exceptions
class LibraryBook(models.Model):
    _name = 'library.book'
