重新排序类别会产生错误422

[hellekin]

我有一个包含 27 个子分类的类别。当我尝试重新排序它们时，保存时会收到“422 不可处理的实体”错误。

[simon]

我无法复现此问题。能否请您在浏览器开发者工具的控制台面板打开的情况下，尝试重新排列分类，看看是否会显示更多关于该错误的详细信息？

[hellekin]

我现在无法处理，但会尽快。在此期间，我已升级到最新的 Discourse 2.4.0.beta5 (302e8f4393)，422 错误已演变为 422 No Reason Phrase。

[Guillermo_Yañez_Sánc (Guillermo Yañez Sánchez)]

我尝试重新排序分类时也遇到了同样的错误。我该怎么办？

非常感谢。

[hellekin]

在此期间，我升级到了 2.4.0.beta7 (15f6f57cdc)，并发现一条错误日志，提示“处理异常应用中间件中的异常时失败：验证失败：自动关闭时间必须大于 0”。

我的多站点设置在某个时间点一定出现了问题，导致该特定站点的某些迁移失败，因为其他站点并未出现此 422 错误。

[Taunusbahner (Sven)]

In the moment, is have the same error but mine is named only “422 error”.
This error comes only when i will order the categories new.

This is the code from my console in Firefox.

Hope I can help you.

[Tom_Newhouse]

我今天在 2.4.0.beta8 版本上也刚开始遇到这个问题。

似乎与类别是否包含子类别无关，即使删除了子类别，某些类别仍然会抛出 422 错误。

[hellekin]

@Tom_Newhouse, @Taunusbahner，你们的日志中是否有“自动关闭时间必须大于 0”的警告？

我最近在另一个论坛编辑了一个分类，自动关闭时间被设置为 0。我将其中的 0 移除后成功保存。

[hellekin]

我想我找到了解决方案。

就我的情况而言，未分类 类别的自动关闭时间被设置为 0，这导致无法保存类别顺序：编辑 未分类 类别并移除这个 0 条目后问题就解决了！

我猜这个 0 是在自动关闭时间配置设置首次出现时引入的，并且被设置为 0（而不是留为 nil）。这个方法对我有效，希望也能解决你的问题。

此话题应移至 Support 并将此帖子选为解决方案，除非团队希望确保此类情况不再发生，并追踪该 bug 以通过编程方式修复它。

[Tom_Newhouse]

未出现该错误，且我这里的“自动关闭主题小时数”字段已为空。

[Tom_Newhouse]

继续进行了更多测试，问题仍然存在。

浏览数据库后发现，存在多个类别位置 ID 冲突，这些冲突与“重新排序类别”界面中显示的内容不一致。

这是否是导致问题的原因？如果是，我们该如何解决？

[Taunusbahner (Sven)]

今天我重新检查了错误，但仍未找到解决方案。

请在 安全模式 下尝试，以排除插件带来的任何疑虑。

请尝试使用浏览器的控制台日志…

@Taunusbahner

在异常应用中间件中处理异常失败：验证失败，slug 无效

这可能是问题所在。您是否有分类的 slug 全是数字？如果是，您能否将该分类的 slug 编辑为其他内容？

[Taunusbahner (Sven)]

各位用户，

同时，我已经找到了我的问题，或者至少我是这么认为的。

在遇到这些问题之前，我从 Yahoo 导入了超过 25000 个主题。
这个分类是否对 Discourse 来说太大了，难以处理？
在我删除这个分类后，论坛运行得就很顺畅了。

[hellekin]

重排序算法的批量处理有上限吗？我预计这个功能会由后台任务处理，@simon？

[simon]

Discourse 代码中未设置可重排类别数量的限制。该操作并非由后台任务处理。我认为出现 422 错误的原因是 reorder 代码调用了 cat.save!。例如，您遇到的问题出在一个“自动关闭小时数”设置为 0 的类别上。这是一个无效设置，因此保存该类别时抛出了错误。

似乎尝试重排大量类别也可能导致错误。

[joe90 (Joe)]

我遇到了这个问题。

我没有启用“允许未分类主题”设置。当我允许未分类主题后，重新排序的保存功能就正常工作了。

[JammyDodger]

我将关闭此问题，因为已经找到了几个解决方案/解决办法。如果有人遇到类似问题，请创建一个新主题。
