在 Jobs::ProcessPost 期间

我可以在命令行中重现：

而我可以通过以下方式成功访问它：

可能与此有关：

FEATURE: Pull hotlinked images immediately after posting

committed 01:28PM - 23 May 22 UTC

Previously, with the default `editing_grace_period`, hotlinked images were pulle…d 5 minutes after a post is created. This delay was added to reduce the chance of automated edits clashing with user edits. This commit refactors things so that we can pull hotlinked images immediately. URLs are immediately updated in the post's `cooked` HTML. The post's raw markdown is updated later, after the `editing_grace_period`. This involves a number of behind-the-scenes changes including: - Schedule Jobs::PullHotlinkedImages immediately after Jobs::ProcessPost. Move scheduling to after the `update_column` call to avoid race conditions - Move raw changes into a separate job, which is delayed until after the ninja-edit window - Move disable_if_low_on_disk_space logic into the `pull_hotlinked_images` job - Move raw-parsing/replacing logic into `InlineUpload` so it can be easily be shared between `UpdateHotlinkedRaw` and `PullUserProfileHotlinkedImages`

              # onebox may have added some links, so extract them now
              def extract_links(post)
                TopicLink.extract_from(post)
                QuotedPost.extract_from(post)
              end
          
              def enqueue_pull_hotlinked_images(post)
                Jobs.cancel_scheduled_job(:pull_hotlinked_images, post_id: post.id)
                Jobs.enqueue(:pull_hotlinked_images, post_id: post.id)
              end
            end
          
          end

在这种情况下，是否需要前导 ::？

david · 2022 年5 月 26 日 11:35

嗯，添加前导的 :: 确实可以解决问题……但它不应该是必需的

鉴于该调用来自 ::Jobs::ProcessPost 内部，Ruby 应该会向上查找。首先它会查找 ::Jobs::ProcessPost::Jobs，然后是 ::Jobs::Jobs，最后是 ::Jobs 模块。

你看到的错误表明有人定义了 ::Jobs::Jobs……这很奇怪！在我自己的开发实例上查看一下：

[1] pry(main)> Jobs::Jobs
=> Jobs::Jobs
[2] pry(main)> Jobs::Jobs.constants
=> [:RemapOldBotImages, :GrantBadges]

看起来 discourse-narrative-bot 中的这些行导致了问题。如果我注释掉它们，问题就解决了。

          if Rails.env == "development"
            # workaround, teach reloader to reload jobs
            # if we do not do this then
            #
            # 1. on reload rails goes and undefines Jobs::Base
            # 2. as a side effect this undefines Jobs::BotInput
            # 3. we have a post_edited hook that queues a job for bot input
            # 4. if you are not running sidekiq in dev every time you save a post it will trigger it
            # 5. but the constant can not be autoloaded
            Rails.configuration.autoload_paths << File.expand_path('../autoload', __FILE__)
          end

好消息是，这是仅在开发环境中出现的——与作业的文件路径与模块名称不匹配有关。这是一个清理问题的 PR：

感谢你的报告 @merefield

啊，是的，这很奇怪，也解释了为什么生产没有崩溃！

感谢您的快速回复！！
