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.

Obtaining an empty recordset for a different model

When writing Odoo code, the methods of the current model are available through self. If you need to work on a different model, it is not possible to directly instantiate the class of that model; you need to get a recordset for that model to start working.

This recipe shows you how to get an empty recordset for any model that's registered in Odoo inside a model method.

Getting ready

This recipe will reuse the setup of the library example in the my_library add-on module.

We will write a small method in the model and search for all library.members. To do this, we need to get an empty recordset for library.members. Make sure you have added the library.members model and access rights for that model.

How to do it...

To get a recordset for library.members in a method of, you need to perform the following steps:

  1. In the LibraryBook class, write a method called get_all_library_members...
