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.

The QWeb parser looks for special directives in the templates and replaces them with dynamically generated HTML. These directives are XML element attributes and can be used in any valid tag or element – for example, <div>, <span>, or <field>.

Sometimes, a QWeb directive needs to be used, but we don't want to place it in any of the XML elements in the template. For these cases, the <t> special element can be used. It can have QWeb directives such as t-if or t-foreach, but it is silent, and it won't have any effect on the final XML/HTML produced.

The QWeb directives frequently use evaluated expressions to produce different effects that depend on record values. The language used to evaluate these expressions depends on the environment where the QWeb is being executed. There are two different QWeb implementations: client-side JavaScript and server-side Python. Reports and website pages use the server-side...
