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.

Defining a model based on a SQL view

When working on the design of an add-on module, we model the data in classes that are then mapped to database tables by Odoo's ORM. We apply some well-known design principles, such as separation of concerns and data normalization. However, at later stages of the module design, it can be useful to aggregate data from several models in a single table, and to maybe perform some operations on them on the way, especially for reporting or producing dashboards. To make this easier, and to make use of the full power of the underlying PostgreSQL database engine in Odoo, it is possible to define a read-only model backed by a PostgreSQL view, rather than a table.

In this recipe, we will reuse the rent model from the Writing a wizard to guide the user recipe in this chapter, and we will create a new model to make it easier to gather statistics about books and authors.

For this recipe, we will use the my_library module from the previous...
