从设计发送延迟电子邮件 [英] Sending delayed email from devise

问题描述

有没有一种简单的方式告诉Devise通过
delayed_job发送所有电子邮件？

解决方案

或者，而不是使用Delayed :: Mailer gem，您可以很容易地实现和使用自己的ActionMailer传递方法，一个...

1. 拦截来自ActionMailer的邮件传递


2. 将电子邮件存储在表（可选）


3. 创建一个引用存储的电子邮件的Delayed :: Job;


4. 延迟工作执行

按照以下方式执行某些操作：

<$ p $在config / application.rb中$ p
ActionMailer :: Base.add_delivery_method：Queued，Mail :: QueuedDelivery

＃在config / environment.rb（或一个的config / environments / * .rb文件）
config.action_mailer.delivery_method =：queued＃ie。 Mail :: QueuedDelivery

＃在lib / mail / queued_delivery.rb
模块邮件
类QueuedDelivery

def initialize（values = {}）
＃（可选）
end

def deliver！（mail）
email = Email.create！（：delivery_handler => mail.delivery_handler.name，：message = mail.to_s）
延迟:: Job.enqueue工作::电子邮件:: DeliverEmail.new（email.id）
end

结束＃class QueueDelivery
end＃module Mail

需要实现的Delayed :: Job然后...

1. 从数据库中检索存储的电子邮件 - email = :: Email.find_by_id（email_id）


2. 通过邮件gem发送电子邮件 - Mail :: Message.new（email.message）.deliver / li>
   

这是...希望这个帮助！

Is there a simple way of telling Devise to send all email via delayed_job?

解决方案

Alternatively, instead of using the Delayed::Mailer gem, you can quite easily implement and use your own ActionMailer "delivery method", one that...

1. intercepts mail delivery from ActionMailer
2. stores the email in a table (optional)
3. creates a Delayed::Job that references the stored email
4. delivers the stored email when the delayed job is executed

Do something along the lines of:

# in config/application.rb
ActionMailer::Base.add_delivery_method :queued, Mail::QueuedDelivery

# in config/environment.rb (or one of the config/environments/*.rb files)
config.action_mailer.delivery_method = :queued # ie. Mail::QueuedDelivery

# in lib/mail/queued_delivery.rb
module Mail
  class QueuedDelivery

    def initialize(values = {})
      # (optional)
    end

    def deliver!(mail)
      email = Email.create!(:delivery_handler => mail.delivery_handler.name, :message => mail.to_s)
      Delayed::Job.enqueue Jobs::Email::DeliverEmail.new(email.id)
    end

  end # class QueueDelivery
end # module Mail

The Delayed::Job you need to implement would then...

1. retrieve the stored email from the database -- email = ::Email.find_by_id(email_id)
2. deliver the email via the mail gem -- Mail::Message.new(email.message).deliver

That's it... hope this help!
