Rails 中的声明 class 已过时?

Statement class in Rails obsolete?

我看到了关于如何在 rails 中实施 PayPal 支付的指南,并且在此代码框中,material 来自 here

Statement.pendings.find_in_batches(batch_size: 500) do |payout_batch|
  @payout = Payout.new({
    :sender_batch_header => {
      :sender_batch_id => SecureRandom.hex(10),
      :email_subject => 'You have received a payment from CookiesHQ'
    },
    :items => payout_items(payout_batch)
  });
end
begin
 @payout_batch = @payout.create
 # Logic to update any statements
rescue ResourceNotFound => err
 logger.error @payout.error.inspect
end

我不知道声明class是否还在使用,我也没有在官方的PayPal文档中找到任何帮助。

I have a Statement table that contains a list of recipients that need paying. It also includes how much we should pay them, along with their PayPal email.

Statement只是教程作者创建的模型,与Rails和PayPal SDK无关。
