Spree::Price objects track a price for a specific currency and variant
combination. For example, if a variant is available for $15 USD or €7 EUR, that
variant would have two Spree::Price objects associated with it (one for each
currency).
If none of a product's Spree::Variants have a price value for the site's
configured currency, that product is not visible in the store frontend.
You can see a variant's price in the store's configured currency by calling the
price method on that instance:
Spree::Variant.find(1).price
# => 15.99You can also call the price method on a Spree::Product. If you call the
price method on a product, it gets the price of the product's master variant.
For a list of all of the Spree::Prices associated with a product or variant,
you can call the prices method on an instance of them:
Spree::Product.find(1).prices
# => [#<Spree::Price id: 2 ...]
# [#<Spree::Price id: 3 ...]
Spree::Variant.find(1).prices
# => [#<Spree::Price id: 4 ...]
# [#<Spree::Price id: 5 ...]
