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

Adding a hierarchy to a Model

Hierarchies are represented using model relations with itself; each record has a parent record in the same model and also has many child records. This can be achieved by simply using many-to-one relations between the model and itself.

However, Odoo also provides improved support for this type of field using the Nested set model (https://en.wikipedia.org/wiki/Nested_set_model). When activated, queries using the child_of operator in their domain filters will run significantly faster.

Staying with the Library Books example, we will build a hierarchical category tree that can be used to categorize books.

Getting ready

We will reuse the my_module addon module from Chapter 4, Creating Odoo Addon Modules...
