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.

Adding a monetary field to a model

Odoo has special support for monetary values related to a currency. Let's see how we can use this in a model.

Getting ready

We will continue to use the my_library add-on module from the previous recipe.

How to do it...

The monetary field needs a complementary currency field to store the currency for the amounts.

my_library already has models/library_book.py, which defines a basic model. We will edit this to add the required fields:

  1. Add the field to store the currency that is to be used:
    class LibraryBook(models.Model): 
    # ... 
    currency_id = fields.Many2one( 
        'res.currency', string='Currency')
  2. Add the monetary field to store the amount:
    class LibraryBook(models.Model): 
    # ... 
    retail_price = fields.Monetary( 
        ...
