How can I save the same form more than once in Django 1.8?

Question

I have a model Product and a corresponding form Product and I need to update the stock with lets say 5 product, so I input the data for the Product and ask how many items of this product I want to store, because all products to save are the same, except for Django default ID, i was thinking of doing something like this in the view:

for i in range(0, 5):
   form.save()

Unfortunately this only saves the last form.

How else can I achieve what I need?

Save one, then create clones of the one from the form

Calling save with commit=False returns an instance that is not saved to the database.

instance = form.save(commit=False)

You can the save the instance multiple times in a loop. By setting the primary key to None, a new object will be saved each time.

for i in range(0, 5):
    instance.pk = None
    instance.save()
