I would like to show records only for certain users what belong to group logged with same state of user_id. Also, if user is not supplier would show all records.

This is the sentence, but don´t work. Thanks in advance.

['|',(user.partner_id,'=', False),('delphos_poblacion_usuario_id.city_id.id','=', user.partner_id.city_id.id)]
