Rails自定义延迟作业-未初始化的常量 [英] Rails Custom Delayed Job - uninitialized constant

问题描述

我已经成功使用了delay_job两年了，但是最近我需要实现某种成功/失败回调/挂钩.

I've been successfully using delayed_job for a couple of years now but recently I have a need to implement some kind of success/failure callback/hooks.

在github上的delay_job指南之后，我设置了以下自定义作业:

Following the delayed_job guide on github i've set up the following custom job:

class XmlImportJob < Struct.new(:file, :supplier_id, :user_id, :directory)
  def perform
    Product.xml_import(file, supplier_id, user, directory)
  end

  def success(job)
    ProductMailer.xml_import_complete.deliver
  end

  def failure(job)
    ProductMailer.xml_import_failed.deliver
  end
end

例如，当使用 Delayed :: Job.enqueue XmlImportJob.new(secure_url，1，1，directory)运行此代码时，我得到一个 Job加载失败:未初始化的常量XmlImportJob.错误.

When running this with Delayed::Job.enqueue XmlImportJob.new(secure_url, 1, 1, directory) for example, I get a Job failed to load: uninitialized constant XmlImportJob. error.

我尝试将我的自定义作业保存在app/jobs和lib下名为 xml_import.rb 的文件中，但出现相同的错误.

I've tried saving my custom job which is in a file named xml_import.rb under app/jobs and lib and I get the same error.

此刻，我只尝试通过Rails控制台运行它.即使显式调用 require'xml_import'返回true，我也会遇到相同的错误.

At the moment i've only tried running this via rails console. Even when explicitly calling require 'xml_import' which returns true I get the same error.

任何有使用自定义delay_jobs经验的人都知道我在这里干什么吗?

Does anyone with experience of using custom delayed_jobs successfully have any idea what I'm doing wring here?

推荐答案

回答我自己的问题；

任何带有要自动加载的类和模块的自定义目录都必须添加到config/application.rb中，如下所示:

Any custom directories with classes and modules you want to be autoloadable must be added to config/application.rb like so:

config.autoload_paths += %W(
  #{config.root}/app/jobs
)

这些文件夹中包含的文件必须根据rails的约定进行命名，以便XmlImportJob驻留在xml_import_job.rb中.

The files contained within these folders must be named according to rails' conventions so XmlImportJob resides in xml_import_job.rb.
