In short, is it possible to build an Amazon clone without substantial modification to Spree?
回答1:
it is indeed possible. If you do, don't use spree as an engine, just use the whole sourcecode as itself. If you use it as an engine, you'll end up overriding so much features of spree that you will be lost totally! Also use and extend the tests that come with spree. You will however loose the ability to update spree, because you will have to change a lot of stuff in the core.
