lets say your product have relation to model example.example which is named in your product model example_id then you need to check if the example_id is null or not by this:
@api.multi
def unlink(self):
for prod in self:
if not prod.example_id:
super(ProductProduct, self).unlink()
but as far as i know product.product model is important model.. which is the original product.product model has many relations to another model..
product_id is foreign key in (sales.order.line or purchase.order.line ) not the opposite
yes and?
