UIまたはCLIからユーザーをマージできません

[McFly (Anthony)]

こんにちはコミュニティの皆さん、

Discourseのバージョン：2.9.0.beta9（42c64abe15）

成功した2つのDiscourseコミュニティがマージされた後、重複ユーザー（特に同じアドレスを入力しなかったユーザー）がいくつか発生しています。

しかし残念ながら、UIに統合されているユーザーマージツールは機能せず、ループしたまま停止しません。
CLIで試しましたが、それも失敗しました。

cd /var/discourse
./launcher enter app

rootユーザーとしてdiscourseから

rake users:merge['olduser','keepuser']

UI経由でインスタンスのユーザーをマージすることはできますか？（モデレーターや管理者ではないことを指摘しておきます）

何かアイデアはありますか？

よろしくお願いします。

以下にトレースを示します。

root@discoursetest-app:~# rake users:merge['olduser','keepuser'] --trace
** Invoke users:merge (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute users:merge

こんにちは。

本日、全く同じ問題に遭遇しました。バージョンは少し古い（2.8.3）ですが、UIとCLIで同じ結果になります。古いユーザーは管理者ではありませんが、新しいユーザーは管理者です。

どなたかこの問題について何か手がかりをいただけると大変助かります。

よろしくお願いします。

I'm attempting to merge user accounts

I encountered a problem like this and thought I should share my findings here in case it might help anyone else who experiences it. In my case, the account merge operation hung forever with the “Merge progress” dialog cycling back and forth between the “Changing post ownership…” and “Updating username…” messages. From looking at the staff action logs (/admin/logs/staff_action_logs), I could see that, although the ownership of many posts was transferred immediately after I triggered the merge…
