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.

Exploring the Odoo external API

Some familiarity with the Odoo external API should be gained before we implement the client app. The following sections explore the XML-RPC API using a Python interpreter.

Using XML-RPC to connect to the Odoo external API

The simplest way to access the Odoo server is by using XML-RPC. The xmlrpc library, from Python standard library, can be used for this.

Remember that the application being developed is a client that connects to a server. So, a running Odoo server instance is needed for the client to connect to. The code examples will assume that an Odoo server instance is running on the same machine, http://localhost:8069, but any reachable URL can be used if the server you wish to use is running on a different machine.

The Odoo xmlrpc/2/common endpoint exposes public methods, and these can be accessed without a login. These can be used to inspect the server version and check login credentials. Let's use the xmlrpc library to explore...
