Ruby on rails 条带令牌未结转至控制器rails 4 问题

我已经测试了CoffeeScript，表单调用Stripe，使用适当的响应令牌设置隐藏字段，然后提交表单。我的问题是，一旦提交了令牌，控制器似乎无法正确获取令牌并抛出此错误：条带：：InvalidRequestError-您必须提供卡或客户id

接下来，我尝试将生成的令牌硬编码到控制器中，看看这是否有效。我提交了表格，工作顺利，最后收到了付款。我几乎不知道下一步该做什么。我想知道我是忘记了什么还是遗漏了什么，因为付款嵌套在作业下

宝石版

• Ruby:2.1.0
• Rails:4.0.1
• 条纹：1.9.9

文件夹 /payment/new.html.erb payment.rb

classpayment

我看到至少有两个问题。我想在进步之后可能会有更多

您无权访问

中的
参数
#使用付款保存"

问题发生在这一行：

# Get the credit card details submitted by the form
token = params[:stripe_customer_token]

参数受强参数保护，您无权访问它

修复方法是允许在

payment_params

中使用所有需要的参数，并在此方法中重用它

实际上，您在

#create

中没有

@price

这个问题与这个问题没有直接关系，但它是存在的

此实例变量

@price

位于

#new

中。而

#create

是另一个实例，因此您不能再次使用它

修复方法是从

支付参数

谢谢你的回复！我已经用你的解决方案更新了价格，这似乎解决了另一个问题。我确实通过将付款添加到params token=params[：payment][：stripe\u customer\u token]中解决了第一个问题

class PaymentsController < ApplicationController
  def new
    set_assignment
    @payment = @assignment.build_payment
    @price = @assignment.price
  end

  def create
    set_assignment
    @payment = @assignment.build_payment(payment_params)

    if save_with_payment
      redirect_to assignments_path, :notice => "Payment received, Thank you!"

      # since payment was successful, set assignment paid to true
      Assignment.update(@assignment, assignment_paid: true, project_status: "In Progress")
    else
      render :new
    end
  end

  private

    def save_with_payment

      # Set your secret key: remember to change this to your live secret key in production
      # See your keys here https://manage.stripe.com/account
      Stripe.api_key = Rails.configuration.stripe[:secret_key]

      # Get the credit card details submitted by the form
      token = params[:stripe_customer_token]

      # How much the assignment costs, which must be converted to cents
      @amount = (@price * 100)

      # Create the charge on Stripe's servers - this will charge the user's card
      begin
        charge = Stripe::Charge.create(
          :amount => @amount,
          :currency => "cad",
          :card => token,
          :description => "some description of the product"
        )
      rescue Stripe::CardError => e
        redirect_to @assignment, :notice => "The card has been declined"
      end
    end

    def set_assignment
      @assignment = Assignment.friendly.find(params[:assignment_id])
    end

    def payment_params
      params.require(:payment).permit(
        :stripe_customer_token
