Obtaining an empty recordset for a different model
The current model’s methods are accessible through self while creating Odoo code. It is not feasible to start working on a different model by simply instantiating its class; you must first obtain a recordset for that model.
This tutorial shows you how to get an empty recordset for any model that’s registered in Odoo inside a model method.
Getting ready
This tutorial will reuse the setup of the library example in the my_hostel add-on module.
We will write a small method in the hostel.room model and search for all hostel.room.members. To do this, we need to get an empty recordset for hostel.room.members. Make sure you have added the hostel.room.members model and access rights for that model.
How to do it…
To get a recordset for hostel.room.members in a method of hostel.room, you need to perform the following steps:
