ruby-on-rails - 创建客户时 strip 错误 : You passed an empty string for 'card'

Question

Stripe 不接受付款，收费一直失败。我收到此错误:

似乎它可能不会创建 strip token ？这是怎么回事？

这是我的表格:

 <% content_for :head do %>
        <%= tag :meta, :name => "stripe-key", :content => STRIPE_PUBLIC_KEY %>
    <% end %>
    <%= form_for @charge, :html => { :class => 'form' } do |f| %>
        <div class="form-inputs">
            <div class="row">
                <%= f.hidden_field :contest_id, value: @contest.id  %>
                <%= f.hidden_field :user_id %>
                <%= f.hidden_field :amount %>
                <!-- TODO CHANGE THIS ACCORDINGLY  -->
                <%= f.hidden_field :stripe_card_token %>
                <div class="small-12 medium-6 large-2 columns">
                    <%= f.label "Amount:", class: "text-right" %>
                </div>
                <div class="small-12 medium-6 large-10 columns" style="margin-bottom: 0.5rem; margin-top: 0.5rem;">
                    <%= number_to_currency(@charge.amount, :unit => "$") %>
                </div>
                <% if @charge.stripe_card_token.present? %>
                  Credit card has been provided.
                <% else %>
                  <div class="small-12 medium-6 large-2 columns">
                    <%= label_tag :card_number, "Credit Card Number:", class: "text-right" %>
                  </div>
                  <div class="small-12 medium-6 large-10 columns">

                  </div>
                  <div class="small-12 medium-6 large-2 columns">
                    <%= label_tag :card_code, "Security Code on Card (CVV):", class: "text-right" %>
                  </div>
                  <div class="small-12 medium-6 large-10 columns end">
                    <%= text_field_tag :card_code %>
                  </div>
                  <div class="small-12 medium-6 large-2 columns">
                    <%= label_tag :card_month, "Card Expiration:", class: "text-right" %>
                  </div>
                  <div class="small-6 medium-3 columns">
                    <%= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"} %>
                  </div>
                  <div class="small-6 medium-3 columns">
                    <%= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year"} %>
                  </div>
                <% end %>
                <div id="stripe_error">
                  <noscript>JavaScript is not enabled and is required for this form. First enable it in your web browser settings.</noscript>
                </div>

            </div>
            <div class="row">
                <div class="form-actions small-9 small-offset-2 columns">
                    <%= button_tag :type => "button", :class => "radius" do  %>
                        <%= link_to "Back", @contest, :style => "color: white" %>
                    <% end %>
                    <%= f.button :Donate, :class => "radius" %>
                </div>
            </div>
        </div>
    <% end %>
    <% content_for :js do %>
        <%= javascript_include_tag "https://js.stripe.com/v1", "application" %> 
        <%= javascript_include_tag asset_path("stripe/stripe.js"), "application" %>
    <% end %>

这是我的收费 Controller :

class ChargesController < ApplicationController

    def new
      @contest = Contest.find(params[:id])
      @charge = Charge.new(amount: params[:amount])
    end

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

    def charges_params
        params.require(:charge).permit(:stripe_card_token, :contest_id, :user_id, :amount)
    end

end

我的收费模型:

class Charge < ActiveRecord::Base

    attr_accessor :stripe_card_token

    belongs_to :contest
    belongs_to :user

    def save_with_payment(charge)
      if valid?
        Stripe::Charge.create(
          :amount => (charge.amount.to_i)*100,
          :currency => "usd",
          :card => stripe_card_token);
        save
      end
    rescue Stripe::InvalidRequestError => e
      logger.error "Stripe error while creating customer: #{e.message}"
      errors.add :base, "There was a problem with your credit card."
      false
    end

end

Answer 1

很可能看起来 stripe_card_token 是空白的

:card => stripe_card_token

试着把它改成

:card => charge.stripe_card_token
