Question

我在我的狂欢应用程序中使用spree_multi_currency gem https://github.com/pronix/spree-multi-currency。它工作，但当我将产品添加到购物车时，它会给出错误，如

undefined method `target_shipment=' for #<Spree::Variant:0xb4ea7b80>

def add_to_line_item(line_item, variant, quantity, currency = nil, shipment = nil)
 if line_item
  line_item.target_shipment = shipment
  line_item.quantity += quantity.to_i
  line_item.currency = currency unless currency.nil?
 else
  .......
end

这是我的全部追踪

提前致谢。

Answer 1

看起来你正在使用的Spree提交中定义的方法与spree_multi_currency中的方法之间存在不匹配。

狂欢： add_to_line_item(variant, quantity, currency, shipment)

Spree_multi_currency： add_to_line_item(line_item, variant, quantity, currency = nil, shipment = nil)

确保您使用扩展程序的正确分支来匹配您的Spree分支。
