Rails的條紋 - 你必須提供一個有效的卡在我的應用程序

Question

我使用的是「條紋」寶石設置付款。一切都很順利，但每當我提交付款時，它都會給我提供錯誤'您必須提供有效的卡'。 以下是我的代碼。

廣告控制器

class AdsController < ApplicationController 
    before_action :set_ad, only: [:show, :edit, :update, :destroy] 


    # GET /ads 
    # GET /ads.json 
    def index 
    @ads = Ad.order('created_at DESC').search(params[:search]) 
    @ads_small = Ad.where(:size => "small").order('created_at DESC') 
    @ads_medium = Ad.where(:size => "medium").order('created_at DESC') 
    @ads_featured = Ad.where(:size => "featured").order('created_at DESC') 

    end 

    def myads 
    @ads_mine = Ad.where(:user_id => current_user.id)

    # GET /ads/1.json 
    def show 
    end

    end 

    private 
    # Use callbacks to share common setup or constraints between actions. 
    def set_ad 
     @ad = Ad.find(params[:id]) 
    end 

    # Never trust parameters from the scary internet, only allow the white list through. 
    def ad_params 
     params.require(:ad).permit(:title, :url, :preview, :location, :size, :info, :search) 
    end 
end

ads.js.coffee

# Place all the behaviors and hooks related to the matching controller here.

# You can use CoffeeScript in this file: http://coffeescript.org/ 

jQuery -> 
    Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content')) 
    ad.setupForm() 

ad = 
    setupForm: -> 
     $('#new_ad').submit -> 
      $('input[type=submit]').attr('disabled', true) 
      ad.processCard() 
      false 

    processCard: -> 
     card = 
     number: $('#card_number').val() 
     cvc: $('#card_code').val() 
     expMonth: $('#card_month').val() 
     expYear: $('#card_year').val() 
     Stripe.createToken(card, ad.handleStripeResponse) 

    handleStripeResponse: (status, response) -> 
    if status == 200 
     $('#ad_stripe_card_token').val(response.id) 
     $('#new_ad')[0].submit() 
    else 
     alert(response.error.message) 
     $('input[type=submit]').attr('disabled', false) 

任何幫助將不勝感激。 :)

在你Ad模型，您有：

attr_accessor :stripe_card_token 

，然後使用令牌save_with_payment：

customer = Stripe::Customer.create(..., card: stripe_card_token) 
self.stripe_customer_token = customer.id 

到目前爲止好。但是你用ad_params當您創建Ad過濾params在你的控制器：

def ad_params 
    params.require(:ad).permit(:title, :url, :preview, :location, :size, :info, :search) 
end 

，我沒有看到允許列表中存在:stripe_card_token任何地方。想必在你的HTML的#ad_stripe_card_token看起來是這樣的：

<input type="hidden" name="ad[stripe_card_token]"> 

所以你應該能夠添加:stripe_card_token到允許列表中ad_params和得到的東西去。
