where is the Exchange Rate for each currency?

[raulperezalejo]

I have seen in Spree3 that this Gem take in the admin interface you should put the price for each currency. Is there any currency rate approach like there use to be before? could someone tell me when did this change took place? Is there any fork for Spree3 working with the exchange rate approach.
I think the rates are a better way to make the approach, don´t know the reasons why this change was made, but the older is more standard, more international and extended.
thank you very much

Not knowing enough about Rails, I will venture to ask if this can be temporarily be done programmatically, as in:
product.price(Product_ID,EUR)=FXRATE*product.price(Product_ID,USD)
Can this be done directly on the database or would it have to pass through some Rails layer?
