在创建动作条件控制器中传递自定义参数

Question

在Stripe的充电控制器的创建动作中，我想获得刚刚支付的命令。但我不知道如何在条形支付表格中传递参数。

这是我的实际代码：

charges_controller

class ChargesController < ApplicationController

  def new
    @command = Command.find(params[:command_id])
    @item = @command.commandable
  end

  def create
    @command = # I would like to have the current command...
    @item = @command.commandable
    # Amount in cents
    amount_in_cents = (@command.total_price * 100).to_i
    customer = StripeTool.create_customer(params[:stripeEmail],
                                          params[:stripeToken])

    charge = StripeTool.create_charge(customer.id,
                                      amount_in_cents,
                                      'Commande Edicouv')

    redirect_to root_path
 end

我在创建动作中的参数：

Processing by ChargesController#create as HTML
Parameters: {"utf8"=>"✓", 
             "authenticity_token"=>"...", 
             "stripeToken"=>"...", 
             "stripeTokenType"=>"card", 
             "stripeEmail"=>"orsay@live.fr"}
