I have a conundrum that I'm _sure_ someone else has already thought of
and solved. How does one best handle the scenario of association
object changes and data integrity?
For example, if I have a standard ecommerce site that sells Products
and people can have Orders and an Order has_many Products... then,
what happens if Product #3 is part of Order #2 but at some point, the
shop owner goes in and edits Product #3 to change it's description...
or it's price... or marks it as "no longer for sale"? Now, Order #2 is
referencing Product #3 via the association but the data in Product #3
is no longer the right data for the Order?
I can imagine a number of ways to handle this, but none of them seem
ideal. I'm curious what people do in this type of (very?) common
