Class Method Details

.from_product_ish(product_ish) ⇒ Object

Create a LineItem from a Spree::LinteItem-ish thing (line_items, products, variants)

All attributes in ATTRIBUTES will be mapped:

When we add a (private) method with the name map_product_ish_sku, this method will be called and get the product_ish to generate a value for that attribute.

When the product_ish has the same attribute name and no mapping-method provided the value, it will simply use the value from that attribute on product_ish
