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.

Chapter 7: Recordsets – Working with Model Data

In the previous chapters, we gave an overview of model creation and loading data into models. Now that we have a data model and some data to work with, it's time to learn more about how to programmatically interact with it.

A business application needs business logic to compute data, perform validations, or automate operations. The Odoo framework API provides the tools for a developer to implement this business logic. Most of the time, this means querying, transforming, and writing data.

Odoo implements an Object-Relational Mapping (ORM) layer on top of the lower level database. The ORM objects provide the Application Programming Interface (API) to be used to interact with the data. This API provides an execution environment and the creation of recordsets, that are objects used to work the data stored in the database.

This chapter explains how to use the execution environment and recordsets so that you have all the...
