Hello,
minimal example...
class School(models.Model):
related_student = fields.One2many('school.student', 'school_student_id')
related_book = fields.Many2many(related='related_student.related_book')
I can see all related students but only 1 book. I want to see all books of all students.
Thank you
self.related_student.mapped('books_field_in_student_model') // this returns all distinct books of this school.
