表条目在开发中工作正常，但在生产中不行答案

【问题标题】：Table entry works fine in development but not in production表条目在开发中工作正常，但在生产中不行
【发布时间】：2019-06-07 09:10:56
【问题描述】：

我有一个产品页面，当您购买产品时，它会重定向到购买页面（收据和下载页面）。

在我的本地计算机上开发中一切正常，但是当购买在远程服务器上进行生产时，它会向客户收费（使用 Stripe）但不会在purchase 表中创建一个条目——不允许客户下载他们的产品。我检查了远程服务器上psql 中的“购买”表，它没有任何行/条目。

它也应该发送一封电子邮件 - 链接到购买页面，这也只能在开发中使用。

我在本地计算机和远程服务器上都使用 PostgreSQL。

充电控制器：

class ChargesController < ApplicationController

  def new
    set_meta_tags noindex: true
  end

  def create
    pack = Pack.find(params[:product_id])

    customer = Stripe::Customer.create(
      :email => params[:stripeEmail],
      :source  => params[:stripeToken],
    )

    # Amount in cents
    charge = Stripe::Charge.create(
      :customer    => customer.id,
      :amount      => pack.price_in_cents,
      :description => 'Product Purchase',
      :currency    => 'usd',
    )

    purchase = Purchase.create(
      email: params[:stripeEmail],
      card: params[:stripeToken],
      amount: pack.price_in_cents,
      description: charge.description,
      currency: charge.currency,
      customer_id: customer.id,
      product_id: pack.id,
      uuid: SecureRandom.uuid,
    )

    redirect_to purchase

  rescue Stripe::CardError => e
    flash[:error] = e.message
    redirect_to new_charge_path
  end

end

purchases_controller：

class PurchasesController < ApplicationController

  def show
    @title = 'Purchase Receipt';
    @purchase = Purchase.find_by_uuid(params[:id])
    @pack = Pack.find(@purchase.product_id)
    set_meta_tags noindex: true
  end

end

购买模式：

class Purchase < ApplicationRecord
  attr_accessor :download_token
  after_create :email_purchaser

  def to_param
    uuid
  end

  def email_purchaser
    PurchaseMailer.purchase_receipt(self).deliver
  end

  def Purchase.new_token
    SecureRandom.urlsafe_base64
  end

  def create_download
    self.download_token = Purchase.email.new_token
    update_attribute(:download, Purchase.email(download_token))
    update_attribute(:download_sent_at, Time.zone.now)
  end

end

purchase_mailer：

class PurchaseMailer < ActionMailer::Base
  layout 'purchase_mailer'
  default from: "First Last <myemail@gmail.com>"

  def purchase_receipt purchase
    @purchase = purchase
    mail to: purchase.email, subject: "Thank you for your purchase. Here's your download link, enjoy!"
  end

end

链接到发送的电子邮件中的 purchase.show 视图：

<%= link_to "DOWNLOAD", purchase_url(@purchase), target: "_blank" %>

这里是服务器日志：

这是在费用控制器中将! 添加到purchase = Purchase.create!( 后的服务器日志：

F, [2019-01-15T21:21:12.869293 #24540] FATAL -- : [932479d4-c710-4ac6-9159-8c3fa5299adc] ActiveModel::UnknownAttributeError (unknown attribute 'uuid' for Purchase.):

这是我的 routes.rb 文件：

  resources :charges
  resources :purchases, only: [:show]

我已经从routes.rb 中删除了get 'purchase' => 'purchases#show', as: 'purchase'，因为它破坏了我的代码。

它使 URL 这样做：https://mywebsite.com/purchase.uuid

而不是这个：https://mywebsite.com/purchase/uuid

这是我的 config/environments/production.rb 文件：

Rails.application.configure do
config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
  config.assets.js_compressor = :uglifier
  config.assets.compile = false
  config.log_level = :debug
  config.log_tags = [ :request_id ]
  config.action_mailer.perform_caching = false
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  host = 'transverseaudio.com'
  config.action_mailer.default_url_options = { host: host }
  ActionMailer::Base.smtp_settings = {
    :address        => 'smtp.sendgrid.net',
    :port           => '587',
    :authentication => :plain,
    :user_name      => ENV['SENDGRID_USERNAME'],
    :password       => ENV['SENDGRID_PASSWORD'],
    :domain         => 'transverseaudio.com',
    :enable_starttls_auto => true
  }
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = ::Logger::Formatter.new
  if ENV["RAILS_LOG_TO_STDOUT"].present?
    logger           = ActiveSupport::Logger.new(STDOUT)
    logger.formatter = config.log_formatter
    config.logger = ActiveSupport::TaggedLogging.new(logger)
  end
  config.active_record.dump_schema_after_migration = false
end

运行后rails routes:

            charges GET    /charges(.:format)                                charges#index
                    POST   /charges(.:format)                                charges#create
         new_charge GET    /charges/new(.:format)                            charges#new
        edit_charge GET    /charges/:id/edit(.:format)                       charges#edit
             charge GET    /charges/:id(.:format)                            charges#show
                    PATCH  /charges/:id(.:format)                            charges#update
                    PUT    /charges/:id(.:format)                            charges#update
                    DELETE /charges/:id(.:format)                            charges#destroy
           purchase GET    /purchases/:id(.:format)                          purchases#show

【问题讨论】：

更新后，你的问题是什么？
你能分享一下你的 rails routes 任务的输出吗？
在您的项目文件夹上运行：“rails routes”如果是 rails 5 或“rake routes”对于旧版本
也许您没有在产品中运行迁移，并且购买表中不存在 uuid 列？
我很高兴能帮上忙。我将在下面提供它作为答案，请接受；）

【解决方案1】：

我建议您将ChargesController.create 包装在事务中。如果Purchase.create 中出现某些（例如验证）错误，您最终会得到一些在 db 中创建的部分数据 + Stripe 中的真实事务。此外，检查purchase 是否已实际创建将是一个很好的改进：

if purchase
  redirect_to purchase
else 
  render :new, error: purchase.errors
end

然后在生产 GUI 中您将清楚地看到问题所在。

另外，在您的日志F, [2019-01-15T21:21:12.869293 #24540] FATAL -- : [932479d4-c710-4ac6-9159-8c3fa5299adc] ActiveModel::UnknownAttributeError (unknown attribute 'uuid' for Purchase.): 中，这可能意味着您的迁移未在 prod 中应用，而您只是缺少 Purchase 中的 uuid 列。

【解决方案2】：

您似乎收到了 HEAD 请求。您的路线似乎无法处理此问题。不用担心，这很正常。

这是正在进行的 CORS 预检检查。在这里阅读更多：https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

和

Why does a cross-origin HEAD request need a preflight check?

对于导轨，试试 Rack Cors： https://github.com/cyu/rack-cors 这可能会有所帮助。

本质上，机架 CORS 将允许您的应用适当地响应预检检查。
