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 addon module my_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.

How to do it…

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

In the LibraryBook class, write a method called get_all_library_members:

class LibraryBook(models.Model):
    # ...
    @api.model
    def get_all_library_members(self):
        # ...

In the body of the method, use the following...
