移动帖子因约束导致 500 错误

贡献 错误

Hi,

A topic started to drift, so I split it to a new topic. Unfortunately, it’s now going back on topic, so I tried to move the relevant posts back to the original one. I’m getting a 500 error.

It seems a constraint is failing:

        WHERE pt.topic_id = mp.old_topic_id
          AND pt.post_number = mp.old_post_number
          AND mp.old_post_id = mp.new_post_id`

这里有明确的复现步骤吗？你能在新主题上重现这个问题吗？

我相当确定这个问题已在 FIX: Existing post timings could prevent moving posts · discourse/discourse@bee000b · GitHub 中修复。
@nmcgovern 如果您仍能复现该问题，请标记以重新打开。
