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.

Creating models

Models are at the heart of the Odoo framework. They describe the application data structures and are the bridge between the application server and the database storage. Business logic can be implemented around models to provide application features, and user interfaces are created on top of them to provide the user experience.

In the following subsections, we will learn about the model's generic attributes, which are used to influence their behavior, and the several types we have available – regular models, transient models, and abstract models.

Model attributes

Model classes can use additional attributes to control some behaviors. These are the most commonly used attributes:

  • _name: This is the internal identifier for the Odoo model we are creating. This is mandatory when creating a new model.
  • _description: This is a user-friendly title that can be used to refer to a single Model record, such as Book. This is optional but recommended...
