我正在尝试使用collectiveidea的delay_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，但是一旦我切换到延迟工作，事情就会崩溃。
我在 delay_job mysql 表中得到的标准错误是:
{undefined method `name' for nil:NilClass...
其中“名称”是邮件程序 View 中的第一个参数 (@contact.name)。如果我再次将 delay_job 拿出来，这很好用。
如果我删除 View 中对 @contact 的所有引用，我会得到
{A sender (Return-Path, Sender or From) required to send a message
简而言之，它似乎根本不理解任何论点。
以下所有相关代码 - 如果有人对此有任何建议，将不胜感激
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
postman :
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
邮件 View :
You have received a new query:
-----------------------------------
<%= @contact.name %>
<%= @contact.business %>
<%= @contact.phone %>
-----------------------
<%= @contact.message %>
-----------------------
初始化程序:
Delayed::Worker.destroy_failed_jobs = false
Delayed::Worker.max_run_time = 5.weeks
最后，完整的错误信息:

最佳答案
问题在于邮件程序中的代码采用对象而不是对象 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
你应该把它改成这样:
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您的邮寄者。只需传递 id 并在处理时检索它们。
