安装问答插件时出现 oops 500 错误

错误
1

你好，我在安装 Pavilion QA 插件时遇到了同样的问题，并在 Oops after updating to discouse 2.9 due to Discourse QA plugin - support - Discourse Meta 中进行了报告。
我今天尝试在 tests-passed (2.9.0.beta6) 中安装 discourse 的 QA 插件，但仍然遇到同样的问题。
如果禁用 QA 插件，一切正常。
我还从 500 error when saving category security settings - bug - Discourse Meta 中找到了类似的错误消息。也许它们有关联？

来自 shared/standalone/log/rails/production.log 的错误消息

我使用了以下模板：

- "templates/postgres.template.yml"
- "templates/redis.template.yml"
- "templates/web.template.yml"
- "templates/web.ratelimited.template.yml"
- "templates/web.socketed.template.yml"
- "templates/cloudflare.template.yml"

并安装了以下插件：

- git clone https://github.com/discourse/docker_manager.git
- git clone https://github.com/discourse/discourse-knowledge-explorer.git
- git clone https://github.com/discourse/discourse-data-explorer.git

它显示了一些与投票相关的内容。投票和问答之间是否存在冲突？

您好，我也尝试解决这个问题。
在 2.9.0 beta 7 中，问题仍然存在。
因为回溯中包含与“投票”相关的内容，我猜测它们之间存在某种冲突。
我删除了投票插件（只安装了问答插件），它就能正常工作了！
希望这能帮助找出问题所在。

抱歉 @yhmtsai，我没看到你关于投票冲突的更新。我的测试站点同时安装了 Voting 和 Q&A，它们似乎相处得很好？我将启动一个新的测试站点，只安装这两个插件，看看这是否能揭示可能发生的情况。

你能想到任何其他可能相关的细节吗？

您好，感谢您的回复。
我重新启用了投票插件，它又能正常工作了。:face_with_raised_eyebrow:
我也尝试先安装投票插件，然后再安装 QA 插件，但它仍然可以正常工作。
我猜可能是 QA 插件的旧版本留下了一些东西，投票插件保留了这些东西，即使删除了 QA 插件也会导致错误。删除投票插件以清理数据后，新的 QA 和投票插件又能一起正常工作了。
不过，我对这些插件的交互不太熟悉，所以只是猜测……

我最近在重建一个新的测试站点时也遇到了类似的问题，问题在于意外地使用了旧的 discourse-feature-voting git 来进行投票插件，而不是当时最新的 discourse-voting，这导致了加载顺序不当。:slight_smile:

两个投票插件最近都已重命名为 discourse-topic-voting 和 discourse-post-voting，因此如果您仍然遇到问题，可以从 app.yml 中删除 discourse-feature-voting 并使用更新的插件，我相信这应该可以解决问题。:+1:

如果 discourse 能在更新 url 时发出一些警告/提醒，那将会有所帮助。
我不确定这是否值得，因为我认为更改名称应该很少发生。
