Ruby on rails Rails操作mailer if语句

我想在我的邮件中加入一些逻辑。基本上，我的一个模型中有十几个布尔字段，对于每个为真的字段，我希望向特定地址发送一封电子邮件。带有布尔字段的模型称为Ecn。这是我的通知程序文件：

class EcnNotifier < ActionMailer::Base
  default from: "engineering_notices@wilfley.com"

  def submitted(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    if @ecn.distribute_engineering?  
        mail to: "abc@gmail.com", subject: 'ECN approvald' 
    else

    end
    if @ecn.distribute_purchasing? 
        mail to: "123@gmail.com", subject: 'ECN approval' 
    else

    end
    mail to: "aaa@test.com", subject: 'ECN approval'
  end
end

---

电子邮件会自动发送到aaa@test.com，但无论distribute_engineering和distribute_purchasing是否正确，电子邮件都不会发送到其他地址。我假设我没有正确访问对象实例，但我不确定哪里出了问题。

一次调用

deliver

只能发送一封邮件。您必须将逻辑移到邮件发送程序之外，或者使用cc或bcc将邮件发送给多个收件人。

我认为您只能在一个邮件发送程序操作中发送一封邮件，而不能发送多封邮件。您可以发送一封邮件并添加一些抄送或密件抄送，但只能在一个操作范围内发送一封邮件

我会将控制器更改为以下内容：

def submit
  @ecn = Ecn.find(params[:id])

  respond_to do |format|
    EcnNotifier.notify_default(@ecn).deliver
    EcnNotifier.distribute_engineering(@ecn).delifer if @ecn.distribute_engineering?
    EcnNotifier.distribute_purchasing(@ecn).deliver if @ecn.distribute_purchasing?
    # and so on...
    format.html { redirect_to ecns_url, alert: "Ecn has been submitted for approval." }
    format.json { render json: @ecns }
  end
end

还有你的电子邮箱：

class EcnNotifier < ActionMailer::Base
  default from: "engineering_notices@wilfley.com"

  def notify_default(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "aaa@test.com", subject: 'ECN approval'
  end

  def distribute_engineering(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "abc@gmail.com", subject: 'ECN approval' 
  end

  def distribute_purchasing(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "abc@gmail.com", subject: 'ECN approval' 
  end

end

classecnnotifier

顺便说一句：如果你要发送多封邮件，你应该通过延迟工作宝石或类似的方式来发送。否则，用户必须等待相当长的时间，因为ruby进程将在发送所有邮件时被阻止。延迟作业gem可在github上获得：

class EcnNotifier < ActionMailer::Base
  default from: "engineering_notices@wilfley.com"

  def notify_default(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "aaa@test.com", subject: 'ECN approval'
  end

  def distribute_engineering(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "abc@gmail.com", subject: 'ECN approval' 
  end

  def distribute_purchasing(ecn)
    @ecn = ecn
    @email_list = EmailList.all
    mail to: "abc@gmail.com", subject: 'ECN approval' 
  end

end
