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

Obtaining an empty recordset for a different model

When writing Odoo code, the methods of the current model are available via self. If you need to work on a different model, it is not possible to directly instantiate the class of that model; you need to get a recordset for that model to start working.

This recipe shows how to get an empty recordset for any model registered in Odoo inside a model method.

Getting ready

This recipe will reuse the setup of the library example in the my_module addon module.

We will write a small method in the library.book model searching for all library.members. To do this, we need to get an empty recordset for library.members.
