Rails：完全被delayed_job困扰。不接受任何论点

标签： ruby-on-rails delayed-job

我正在尝试使用collectiveidea的delayed_job在Rails 3应用程序中发送邮件。如果我尝试定期发送邮件（.deliver）它工作正常，但一旦我转到延迟工作，事情就会崩溃。

我在delayed_job mysql表中遇到的标准错误是：

  

{undefined method`name'for   零：NilClass ...

其中'name'是邮件程序视图中的第一个参数（@ contact.name）。如果我再次使用delayed_job，这样可以正常工作。

如果我删除视图中对@contact的所有引用，我会得到

  

{发件人（Return-Path，Sender或   From）需要发送消息

简而言之，似乎根本不理解任何论据。

以下所有相关代码 - 如果有人对此有任何建议，将非常感谢

CONTROLLER 

  def sendmail
    @contact = Contact.new(params[:contact])
    if @contact.save
      ContactMailer.delay.contact_mail(@contact)
      flash[:notice] = 'Your message has been successfully sent'
      redirect_to root_path
    else
      render :action => 'index'
    end
  end

MAILER：

class ContactMailer < ActionMailer::Base
  default :from => "my@email.address"  

  def contact_mail(contact)
    @contact = contact
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain')
  end
  handle_asynchronously :contact_mail, :run_at => Proc.new { 2.seconds.from_now }
end

MAILER VIEW：

You have received a new query:
-----------------------------------

<%= @contact.name %>

<%= @contact.business %>

<%= @contact.phone %>

-----------------------
<%= @contact.message %>
-----------------------

初​​始化：

问题在于邮件中的代码是使用对象而不是对象id：

def contact_mail(contact)
    @contact = contact
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain')
end

你应该改变它：

def contact_mail(contact_id)
    @contact = Contact.find(contact_id)
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain')
end

切勿将实际对象传递给邮件程序。只需传递id并在处理时检索它们。

我有同样的问题，并通过将所有属性移动到实例变量来修复它。所以，在视图中：

<%= @contact.name %>
<%= @contact.business %>
<%= @contact.phone %>

变为：

<%= @name %>
<%= @business %>
<%= @phone %>

我只是在邮件程序方法中查找了实例变量。所以，在邮件中：

def contact_mail(contact)
    @contact = contact
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain')
end

变为：

def contact_mail(contact)
    @name = contact.name
    @business = contact.business
    @phone = contact.phone
    mail(:to => 'my@email.address', :subject => 'Contact Form Query', :from => 'my@email.address', :content_type => 'text/plain')
end

为什么不起作用？不确定，我想它与一些ActionMailer伏都教有关。

如何让它运作？摘要将延迟的工作分成另一类。有延迟的方法只是发送电子邮件;这意味着电子邮件的呈现是实时完成的，但是它的发送被延迟了。这应该解决您的问题并完成电子邮件的异步发送。

答案 3 :(得分：0)

嘿，这可能很遥远，但你没有向你的MAILER发送任何参数。这是我保存在lib / dir中的referenced_email.rb的副本。我用delayed_job称呼它：

#my controller
Delayed::Job.enqueue ReferredEmail.new(params[:subject], params[:editor1])

#Reffered_Email.rb

class ReferredEmail < Struct.new(:subject, :editor1)
  def perform
    (CardReferral.all.map(&:email) - CardSignup.all.map(&:email)).each do |cf|
      @cf = CardReferral.find_by_email(cf)
      Notifier.deliver_referred_magic_email(User.find(@cf.user_id), @cf.email, @cf.name, @cf.message, subject, editor1)
    end
  end
end

答案 4 :(得分：0)

好像你正在使用两者：

  ContactMailer.delay.contact_mail(@contact)

和

  handle_asynchronously :contact_mail, :run_at => Proc.new { 2.seconds.from_now }

你应该只做一个或另一个。尝试删除handle_asynchronously并查看是否可以解决问题。
