Obtaining an empty recordset for a different model

When writing Odoo code, the methods of the current model are available through 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 you how to get an empty recordset for any model that's registered in Odoo inside a model method.

Getting ready

This recipe will reuse the setup of the library example in the my_library add-on module.

We will write a small method in the library.book model and search for all library.members. To do this, we need to get an empty recordset for library.members. Make sure you have added the library.members model and access rights for that model.

How to do it...

To get a recordset for library.members in a method of library.book, you need to perform the following steps:

1. In the LibraryBook class, write a method called get_all_library_members...
