    Metadata details:
    filename: cart_products_controller.rb
    path of file: ./repos/convene/app/furniture/marketplace
    
    the code of the file until where you have to start completion: class Marketplace

    expose :cart_product, scope: -> { policy_scope(cart.cart_products) }, model: CartProduct

    def create
   
    
    def destroy
      authorize(cart_product).destroy

      if cart_product.destroyed?
        flash[:notice] =
          t(".success", product: cart_product.product.name.pluralize(cart_product.quantity),
            quantity: cart_product.quantity)
      else
        flash[:alert] =
          t(".failure", product: cart_product.product.name.pluralize(cart_product.quantity),
            quantity: cart_product.quantity)
      end
