ruby-on-rails – Delayed_job：任何调用都有未定义的方法错误

我触摸应用程序已经有几周了,但我只是去调整它,发现delayed_job已经坏了.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.一些东西：

>用StudentMailer.student_mail(‘test’)替换StudentMailer.delay.student_mail(‘test’).deliver传送邮件就好了.
>没有更改网站上的任何宝石版本,他们自开发以来一直处于锁定状态
>已卸载RVM&重新安装
>发生在所有邮件方法中

代码&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)

延迟工作错误：
