设计，如何覆盖send_confirmation_instructions

我正在尝试覆盖方法’send_confirmation_instructions’，如下所示：

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

有：

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计。 设计文档显示如何覆盖控制器而不是模型。 有关如何覆盖设计模型的任何建议？ 谢谢

Answer 1

当您设置Devise时，您可以告诉它正在处理哪个模型（例如User）; 然后，许多/大部分方法都适用于该类。 所以这就是你想要覆盖的东西。

这是来自lib/devise/models/authenticatable.rb中的Devise代码的注释，如果我正确阅读，它几乎准确地描述了您想要做的事情。

  # 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

为什么不使用devise-async ？

 Usage Devise >= 2.1.1 Include Devise::Async::Model to your Devise model class User < ActiveRecord::Base devise :database_authenticatable, :confirmable # etc ... include Devise::Async::Model # should be below call to `devise` end Devise < 2.1.1 Set Devise::Async::Proxy as Devise's mailer in config/initializers/devise.rb: # Configure the class responsible to send e-mails. config.mailer = "Devise::Async::Proxy" All Set your queuing backend by creating config/initializers/devise_async.rb: # Supported options: :resque, :sidekiq, :delayed_job Devise::Async.backend = :resque
