Hello everyone,

I'm new here, and i'm so happy to join this big and generous family,

I'm asking about version 9, i want some explication about the Odoo tutorial in the community website 'openacademy', and exactly about the relation of the two classes (Course / Res.User)

So my question is : why we don't have the reverse relationship One2Many ine the class User for responsible_id in the model Course ?

The course says that for every Many2One there's a One2Many relationship in the other side, but not used on that tutorial, why i'm wondering.

Thanks for you all
