Question

我有一个rails 3.0.5应用程序，与delayed_job 2.1.4一起正常工作。

自从我触摸应用程序已经有几周了，但我只是去调整它并注意到delayed_job被破坏了。具体来说，对delayed_job的任何调用都会在延迟后返回方法上的“未定义方法”错误。（例如，StudentMailer.delay.student_mail（'test'）在“student_mail”上返回“未定义的方法”）我无法弄清楚原因。一些事情：

使用StudentMailer.student_mail（'test'）替换StudentMailer.delay.student_mail（'test'）。deliver可以很好地发送邮件。
网站上没有更改任何宝石版本，自开发以来一直被锁定
已卸载RVM＆amp;重新安装
发生所有邮件程序

代码＆amp;错误如下：

MAILER：

class StudentMailer < ActionMailer::Base
  def course_signup(email, password, course, enrolment)
    @email = email
    @password = password
    @course = course
    @enrolment = enrolment
    @student = Student.where(:email => email).first
    if (@student.user.first_name && @enrolment.student.user.last_name) then
      @username = @student.first_name.gsub(/[^[:alnum:]]/, '').downcase + '.' + @student.last_name.gsub(/[^[:alnum:]]/, '').downcase
    else
      @username = "fcuser#{@student.id}"
    end
    mail(:to => email, :from => ENV['ACCOUNTS_EMAIL'], :subject => "You have been enrolled as a student for #{course}", :content_type => 'text/plain') 
  end
end

MODEL（梅勒呼吁after_save）

  after_create {
    studentmailer = StudentMailer
    #studentmailer.course_signup(self.student.email, self.purchase.course).deliver
    randompass = RandomPassword.random_string(20)
    randomGatewayPass = RandomPassword.random_string(8)
    studentmailer.delay.course_signup(self.student.email, randomGatewayPass, self.purchase.course, self)
    self.save   }

CONFIG /的boot.rb

require 'yaml'
YAML::ENGINE.yamler = 'syck'

require 'rubygems'
gemfile = File.expand_path('../../Gemfile', __FILE__)
begin
  ENV['BUNDLE_GEMFILE'] = gemfile
  require 'bundler'
  Bundler.setup
rescue Bundler::GemNotFound => e
  STDERR.puts e.message
  STDERR.puts "Try running `bundle install`."
  exit!
end if File.exist?(gemfile)

Answer 1

我在谷歌搜索同样的问题，我找到了解决方案（这对我有用）。

将这两行添加到config / application.rb

的头部

要求'yaml'

YAML :: ENGINE.yamler ='syck'

然后，重启你的服务器（webrick / thin / whatever）和delayed_job （bundle exec ./script/delayed_job restart）

进行。

Answer 2

我遇到了同样的问题。如果你使用瘦，请尝试“捆绑exec瘦启动”。它对我有用。

Answer 3

尝试更改方法定义

 def self.course_signup

或

 studentmailer = StudentMailer.new

因为现在你从类调用方法但方法属于对象

Delayed_job：任何调用上的未定义方法错误
