Ruby on rails 条带：参数丢失或值为空：费用

我正试图找出如何将自定义条带表单集成到barebones rails应用程序中，但到目前为止，这是一段艰难的时间

我遇到错误：

param丢失或值为空：费用

这是我的收费管理员：

class ChargesController < ApplicationController

    def new
      @charge = Charge.new
    end

    def create
      @charge = Charge.new
      if @charge.charging_card(charges_params)
        redirect_to root_path, :notice => "Contribution was recorded succesfully!"
      else
        redirect_to about_path, :notice => "Transaction was not able to be recorded"
      end
    end

    def charges_params
        params.require(:charges).permit(:stripe_card_token)
    end


end

这是我的服务器日志：

我想我不明白为什么强参数中的电荷是空的

---

任何其他的建议或建议，你可以从我的代码，可以帮助我完成这个项目将不胜感激

尝试将强参数更改为以下内容：

def charges_params
  if params[:charges] && params[:charges][:stripe_card_token].present?
    params.require(:charges).permit(:stripe_card_token)
  end
end

你能发布你生成的服务器日志吗？@Pavan我刚刚在问题的末尾添加了我的日志输出。谢谢。这一行

@charge=charge.new

在你的创建操作中应该是

@charge=charge.new（charge\u params）

我猜。我没有看到

在你的
创建
操作中的
保存
，如果@charge.charge\u params）
卡（charge\u params）
怎么办？当我做@charge=charge.new（charge\u params）时我一访问我的“费用”视图就会出错。。我得到以下信息：param丢失或值为空：chargeThat worked。。为什么会这样？不幸的是，现在我在日志中看到另一个问题，即“创建客户时出现条带错误：您必须提供卡或客户id”，因为您没有发送参数“费用”来创建
ActiveRecord::Schema.define(version: 20140723082502) do

  create_table "charges", force: true do |t|
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "stripe_card_token"
    t.decimal  "amount"
  end
