Question

我正在使用Mongoid和delayed_job_mongoid宝石。一切都在最新版本，包括Rails（3.2.3）。

我理解如果在任何方法声明之后我把handle_asynchronously，这个方法将始终运行async。但是我得到了这样的未定义方法错误：

class Item
  # mongoid include stuff

  def shout
    puts 'a simple hi'
  end
  handle_asynchronously :shout
end

item = Item.create
item.shout # returns a delayed job object

j = _
# wait a moment
j.last_error 

{undefined method `shout_without_delay' for #<Item:0x007f8365e62978>

但如果我打电话

item.delay.shout

没有handle_asynchronously行

它会起作用！

有什么想法吗？谢谢！

这是该帖子的作者。我发现了发生了什么。简短回答：您必须重新启动终端中的工作人员

[control + c]
rake jobs:work

对于mongoid延迟作业能够找到该方法。我不知道为什么。所以只要记住每当你添加另一行handle_asynchronously时重启worker：方法

快乐的编码！

你的语法应该是

class Item
   # mongoid include stuff

   def shout
      puts 'a simple hi'
   end
   handle_asynchronously :shout
end

delayed_job_mongoid不能使用handle_asynchronously，但可以使用.delay.method
