设计如何覆盖 send_confirmation_instructions

我正在尝试重写方法“send_confirmation_instructions”，如下所示：

http://trackingrails.com/posts/devise-send-confirmation-mail-manually-or-delay-them http://trackingrails.com/posts/devise-send-confirmation-mail-manually-or-delay-them

with:

def send_confirmation_instructions
    generate_confirmation_token! if self.confirmation_token.nil?
    ::Devise.mailer.delay.confirmation_instructions(self)
end

这似乎不再适用于最新版本的设备。设计文档展示了如何覆盖控制器而不是模型。关于如何覆盖设计模型有什么建议吗？谢谢

当您设置 Devise 时，您可以告诉它正在使用哪个模型（例如用户）；然后它的许多/大部分方法适用于该类。所以这就是你想要覆盖的地方。

这是来自 Devise 代码的评论lib/devise/models/authenticatable.rb如果我没读错的话，这几乎准确地描述了你想要做的事情。

  # This is an internal method called every time Devise needs
  # to send a notification/mail. This can be overriden if you
  # need to customize the e-mail delivery logic. For instance,
  # if you are using a queue to deliver e-mails (delayed job,
  # sidekiq, resque, etc), you must add the delivery to the queue
  # just after the transaction was committed. To achieve this,
  # you can override send_devise_notification to store the
  # deliveries until the after_commit callback is triggered:
  #
  #     class User
  #       devise :database_authenticatable, :confirmable
  #
  #       after_commit :send_pending_notifications
  #
  #       protected
  #
  #       def send_devise_notification(notification)
  #         pending_notifications << notification
  #       end
  #
  #       def send_pending_notifications
  #         pending_notifications.each do |n|
  #           devise_mailer.send(n, self).deliver
  #         end
  #       end
  #
  #       def pending_notifications
  #         @pending_notifications ||= []
  #       end
  #     end
  #
  def send_devise_notification(notification)
    devise_mailer.send(notification, self).deliver
  end
