Overview of this book

Odoo is fast becoming the reference open source platform for business applications thanks to the fact that it provides the infrastructure needed for developers to deliver software solutions for any business process quickly. Odoo's layered module approach makes it particularly effective for combining and extending features. This updated fifth edition is a tutorial-style introduction to essential Odoo development topics. The book starts by covering the development essentials for building business applications and takes you through Odoo installation and configuration, gradually transitioning from having no specific knowledge of Odoo to being ready for application development. You'll then learn how to develop your first Odoo application, while covering topics such as models and views. Later chapters will get you up to speed with using server APIs to add business logic, helping you lay a solid foundation for advanced topics. As you progress, you’ll get equipped to build and customize your applications and explore the new features available in Odoo 12 and beyond, such as in-memory ORM and computed writable fields. Finally, you’ll gain insights into building business logic and using the Odoo API to integrate with various applications. By the end of this book, you’ll be able to build business apps from scratch using the latest version of Odoo.

An addon module is a directory containing files that implement some Odoo features. It can add new features or modify existing ones. The addon module directory must contain a manifest file—or descriptor file—named __manifest__.py.

Some module addons are featured as an app. Apps are the top-level module for a feature area in Odoo, and we expect our module to be featured in the top-level Apps menu. Examples of apps in base Odoo include CRM, Project, and HR. A non-app module addon is expected to depend on an app, adding or extending features to it.

If a new module adds new or major functionality to Odoo, it probably should be an app. If the module just makes changes to an existing app, it probably should be a regular addon module.

To develop a new module, we will do the following:

  1. Ensure that the directory where we will work is in the Odoo server addons path.
  2. Create the module's directory, containing the...
