我正在尝试让用户在点击"添加到购物车"之后重定向到他们的current_cart。链接。我在行项目控制器中这样做,并使用railscasts源代码作为参考。 https://github.com/ryanb/railscasts-episodes/blob/master/episode-141/store/app/controllers/line_items_controller.rb
当我点击"添加到购物车"链接我收到此错误:
未定义的局部变量或方法`current_cart'
这是我的LineItemsController:
class LineItemsController < ApplicationController
def create
@product = Product.find(params[:product_id])
@line_item = LineItem.create!(:cart => current_cart, :product => @product,
:quantity => 1, :unit_price => @product.price)
flash[:notice] = "Added #{@product.title} to cart."
redirect_to current_cart_url
end
end
这是我的CartsController:
class CartsController < ApplicationController
def show
@cart = current_cart
end
end
感谢您的帮助。

您的订单项控制器看起来缺少current_cart方法:
def current_cart
# where you should find your current cart, i.e.
@current_cart ||= Cart.find(session[:cart_id])
end
