Hi everyone,

i'm completely new to odoo and i'd like some help for something i'm doing.
I extended the product.product model, and added a m2m relation with the class itself, so a product can be "linked" to another product.

Now, i would like to be able to add those "linked products" to my sale_order when i add the "master" product.

I extended the sale_order class and i'm trying to redefine the method _create, but i don't know what to do next. I can't iterate on self.order_line :/

@api.model

def create(self, vals):

     for line in self.order_line:

        print("add new line")

     return super(sale_order,self).create(vals)

Thanks a lot for your help!
