Odoo 11 Development Cookbook - Second Edition - Second Edition

Overview of this book

Odoo is a full-featured open source ERP with a focus on extensibility. The flexibility and sustainability of open source are also a key selling point of Odoo. It is built on a powerful framework for rapid application development, both for back-end applications and front-end websites. Version 11 offers better usability and speed: a new design (as compared to the current Odoo Enterprise version) and a mobile interface. The book starts by covering Odoo installation and administration and Odoo Server deployment. It then delves into the implementation of Odoo modules, the different inheritance models available in Odoo. You will then learn how to define access rules for your data; how to make your application available in different languages; how to expose your data models to end users on the back end and on the front end; and how to create beautiful PDF versions of your data. By the end of the book, you will have a thorough knowledge of Odoo and will be able to build effective applications by applying Odoo development best practices

Traversing recordset relations

When working with a recordset of length 1, the various fields are available as record attributes. Relational attributes (One2many, Many2one, and Many2many) are also available with values that are recordsets too. When working with recordsets with more than one record, the attributes cannot be used.

This recipe shows you how to use the mapped() method to traverse recordset relations; we will write two methods performing the following operations:

  • Retrieving the emails of all contacts of one or more companies passed as an argument
  • Retrieving the various companies to which some contact partners are related

Getting ready

We will reuse the simplified Partner model shown in the Create new records recipe...
