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.

Using XML data files

While CSV files provide a simple and compact format to represent data, XML files are more powerful and give more control over the loading process. For example, their filenames are not required to match the model to be loaded. This is because the XML format is much richer and more information regarding what to load can be provided through the XML elements inside the file.

We used XML data files in the previous chapters. The user interface components, such as the views and menu items, are, in fact, records that are stored in system models. The XML files in the modules are used to load these records into the instance database.

To showcase this, a second data file will be added to the library_app module, data/book_demo.xml, with the following content:

<?xml version="1.0"?>
<odoo noupdate="1">
  <!-- Data to load -->
  <record model="res.partner" id="res_partner_huxley"> 
&...
