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 fields

Inside a form or list view, fields widgets are the way to present and edit data from model fields.

View fields have a few attributes available to them. Most of these attribute values have defaults that are taken from the model definition, but these can be overridden in the view.

Here is a quick reference for the common field attributes:

  • name is the field name in the model and identifies the field that's being rendered by this element.
  • string is the label text to be used. It overrides the model definition.
  • help provides some tooltip help text that's shown when the mouse is hovered over the field.
  • placeholder provides suggestion text to be displayed inside the field.
  • widget sets a specific widget to be used to render the field. The available widgets will be discussed later in this section.
  • options is a JSON data structure that's used to pass additional options to the widget. The values to use depend on the widget being used...
