升级页面为空

BryanV · 2021 年12 月 2 日 19:53

我今天收到了一条关于升级的通知，但导航到升级页面后，发现它是空白的：

我看到有几个关于这个问题的帖子，大家的共识似乎是手动重建。但问题是，我两天前才刚刚手动重建过，当时我安装了我刚编写的一个自定义 Onebox 插件：

https://github.com/bokeh/discourse-bokeh-onebox

我想了解为什么会出现这个空白页面。是我的简单插件有什么问题导致了这种情况，还是我需要更改什么？这与插件无关吗？如果无关，我该如何避免将来再次出现这种情况？

JammyDodger · 2021 年12 月 2 日 20:22

如果禁用插件的安全模式，是否也会发生这种情况？这或许能帮助你缩小问题范围。

[YourSite]/safe-mode

BryanV · 2021 年12 月 2 日 20:36

/upgrade 链接已从安全模式的 /admin 页面中移除，手动导航至该页面也无法正常工作

哎呀！该页面不存在或为私有页面。

JammyDodger · 2021 年12 月 2 日 20:50

如果取消勾选“禁用所有插件”，但保留其他两个，它就在那里。禁用官方插件会禁用 docker-manager，但您仍然应该能够检查主题和非官方插件，如果这对您有帮助的话？

Steven · 2021 年12 月 2 日 21:12

在升级页面输入F12后，控制台是否有任何红色警报？

BryanV · 2021 年12 月 2 日 21:16

@JammyDodger 啊，谢谢。不，那没有帮助，升级页面是完全空白的，即使在安全模式下禁用主题和非官方插件也是如此。

@Steven 是的，这是在 JS 控制台日志中

BryanV · 2021 年12 月 3 日 00:30

所以，总结一下，页面似乎是空白的，因为 AJAX 请求到

https://discourse.bokeh.org/admin/docker/repos

时返回了 500 HTTP 错误。
对此有什么已知的解释吗？除了手动重建之外，还有什么纠正措施吗？

Falco · 2021 年12 月 3 日 00:44

如果出现 500 错误，/logs 应该会有一个相应的条目。

BryanV · 2021 年12 月 3 日 01:30

@Falco 谢谢，我之前不知道这个端点。错误是

您安装的一个插件的名称为 nil

github.com/discourse/docker_manager

app/controllers/docker_manager/admin_controller.rb

4e06649d3


      
            result = {
              name: r.name,
              path: r.path,
              branch: r.branch,
              official: Plugin::Metadata::OFFICIAL_PLUGINS.include?(r.name)
            }
          
            result[:fork] = true if result[:official] && !r.url.starts_with?("https://github.com/discourse/")
          
            if r.valid?
              result[:id] = r.name.downcase.gsub(/[^a-z]/, '_').gsub(/_+/, '_').sub(/_$/, '')
              result[:version] = r.latest_local_commit
              result[:pretty_version] = r.latest_local_tag_version.presence
              result[:url] = r.url
              if r.upgrading?
                result[:upgrading] = true
                result[:version] = r.upgrade_version
              end
            end
            result
          end

您可以在 Rails 控制台中运行 DockerManager::GitRepo.find_all 来检查此问题来源。

@Falco 我猜（假设）那会是我的 Onebox 插件，虽然我不确定为什么安全模式下也无法正常工作。无论如何，我从零开始，从未写过 Ruby，拼凑出了这个文件，如果你知道在哪里/如何指定“name”，我将不胜感激：

https://github.com/bokeh/discourse-bokeh-onebox/blob/main/plugin.rb

Falco · 2021 年12 月 3 日 02:02

也许可以参考一下这个例子

github.com/discourse/docker_manager

plugin.rb

4e06649d3


      
          # frozen_string_literal: true
          
          # name: docker_manager
          # about: Docker manager for Discourse image
          # version: 0.1
          # authors: Robin Ward, Sam Saffron
          # url: https://github.com/discourse/docker_manager
          
          if !defined? ::Discourse.redis
            # HACK: make Discourse.redis work on old versions of Discourse
            module ::Discourse
              def self.redis
                $redis # rubocop:disable Style/GlobalVars

BryanV · 2021 年12 月 3 日 02:26

我确实参考了几个例子，只是我从未想过这个名字是从注释中解析出来的，而不是配置为实际数据/代码。我会更新我的插件并重新构建，谢谢。
