It sounds a lot like you should rethink your models. Would any of those
routes make sense for what you are doing?

foobar.com/quantity/new ?
foobar.com/location/new ?

No they dont. What would make sense is this:
foobar.com/reservation/new or foobar.com/order/new

So when creating a new order you can choose the products, the quantity
and show the location of the products. Otherwise you are making the
product or the location model do something that they shouldnt really be
doing.

This would be my approach at least.
