ruby-on-rails - Ruby on Rails 如何构建支付模型来处理 Paypal REST SDK

Question

我想根据官方 Paypal Example on Github 创建一个支付模型.但我一直在创建具有所需字段的模型。

Payment.new({
    :intent => "sale",
    :payer =>  {
        :payment_method =>  "paypal" },
    :redirect_urls => {
        :return_url => "http://localhost:3000/payment/execute",
        :cancel_url => "http://localhost:3000/" },
    :transactions =>  [{
        :item_list => {
          :items => [{
            :name => "item",
            :sku => "item",
            :price => "5",
            :currency => "USD",
            :quantity => 1 }]},
        :amount =>  {
          :total =>  "5",
          :currency =>  "USD" },
    :description => "This is the payment transaction description." }]})

从 rails g model Payment intent:string 开始......我不知道如何创建像

这样的嵌套字段

:redirect_urls => {
    :return_url => "http://localhost:3000/payment/execute",
    :cancel_url => "http://localhost:3000/" }

更深入

:transactions =>  [{
    :item_list => {
      :items => [{
        :name => "item",
        :sku => "item",
        :price => "5",
        :currency => "USD",
        :quantity => 1 }]},

感谢您的帮助!

您可以使用 OpenStruct为你做这件事。它将是这样的:

paypal_hash = {
    :intent => "sale",
    :payer =>  {
        :payment_method =>  "paypal" },
    :redirect_urls => {
        :return_url => "http://localhost:3000/payment/execute",
        :cancel_url => "http://localhost:3000/" },
    :transactions =>  [{
        :item_list => {
          :items => [{
            :name => "item",
            :sku => "item",
            :price => "5",
            :currency => "USD",
            :quantity => 1 }]},
        :amount =>  {
          :total =>  "5",
          :currency =>  "USD" },
    :description => "This is the payment transaction description." }]}

paypal_obj = OpenStruct.new(paypal_hash)
paypal_obj.intent
# => "sales"
