Hello, I have Odoo8.
I have a model A with a many2many field which relates him with a model B. I want to filter this many2many field with a domain, which filters (not consider) all the B records which has one relation to any A record. How can I do this? Thanks!
@Ivan, thanks for your reply. In model B I don't have any reference to model A. How can count the number of model A related to model B in a function field?
