Hi! I have a one2many field with some calculated fields. I need to save changes in database when I change the one2many, so my calculated fields run ok. Now, I need press Save button upper the page before to add another record in my one2many, and this is a little unconfortable. So I need that when you modify a record on my one2many, the changes will automatically be recorded in the database. I know that save data in a on_change method is far less correct, but would need to know if this can be done and how it would. thank you very much and sorry for my english
