delay_job：NoMethodError [英] delayed_job: NoMethodError

问题描述

这是我的小型Rails3控制器：

  class HomeController< ApplicationController 
 def index 
 HomeController.delay.do_stuff 
 end 
 def self.do_stuff 
放置 Hello 
 end 
 end 
  

访问 index 后，作业将正确插入数据库中：

  ---！ruby / struct：Delayed :: PerformableMethod 
对象：！ruby / object：Class HomeController 
 method_name：：do_stuff 
  

问题：执行<$时c $ c> bundle exec rake jobs：work ，我得到：

  Class＃do_stuff失败， NoMethodError：＃b< Class：0x0000000465f910>的
未定义方法`do_stuff' 
  

尽管 HomeController.do_stuff 起作用完美。有想法吗？

解决方案

请参见 https://github.com/collectiveidea/delayed_job/wiki/Common-problems#wiki-undefined_method_xxx_for_class 在文档中。

似乎您应该拥有

.. object：！ruby / class HomeController method_name ...

在数据库中，但是您有

.. object :！ ruby / object：Class HomeController method_name ...

。

即使delay_job作者也不知道原因。它在某种程度上取决于您所运行的Web服务器。试试维基的建议。

Here is my tiny Rails3 controller:

class HomeController < ApplicationController
  def index
    HomeController.delay.do_stuff
  end
  def self.do_stuff
    puts "Hello"
  end
end

Upon accessing index, the job gets correctly inserted in database:

--- !ruby/struct:Delayed::PerformableMethod 
object: !ruby/object:Class HomeController
method_name: :do_stuff

PROBLEM: When executing bundle exec rake jobs:work, I get:

Class#do_stuff failed with NoMethodError:
    undefined method `do_stuff' for #<Class:0x0000000465f910>

Despite the fact that HomeController.do_stuff works perfectly. Any idea?

解决方案

See https://github.com/collectiveidea/delayed_job/wiki/Common-problems#wiki-undefined_method_xxx_for_class in documentation.

It seems that you should have

..object: !ruby/class HomeController method_name ...

in the database, but you have

..object: !ruby/object:Class HomeController method_name ...

instead. Which is bad.

Even delayed_job author don't know the reason. It somehow depends on the webserver you run in on. Try the wiki's recommendation.
