「ユーザーに通知」フラグ付きPMを奨励する

データとレポート

We want to encourage users to write more private messages about contentious or personal feedback on posts (and do it in a civil and friendly way…), rather than posting it public and possibly steering the conversation off-topic. Here’s the badge:

helpful-badge
helpful-badge847×245 14.2 KB

The query:

SELECT p.user_id, current_timestamp AS granted_at
FROM posts AS p
JOIN topics t on t.id = p.topic_id
WHERE t.archetype = 'private_message'
AND t.title LIKE 'Your post in "%"'
AND p.post_number = 1
AND p.like_count >= 1
AND (:backfill OR p.user_id IN (:user_ids))
GROUP BY p.user_id
HAVING count(*) >=1

I didn’t find a specific trigger for flag messages, so the query uses the default title “Your post in …”. I’d say the badge is easy to game or cheat in several ways, but it would still achieve it’s goal just by giving more visiblity to this feature and communicating that this is regarded positive action for the community.

これは「ユーザーに通知」の post_action に基づいているのでしょうか？

SELECT pa.user_id, current_timestamp AS granted_at
FROM post_actions pa
  JOIN posts p ON p.id = pa.related_post_id
WHERE pa.post_action_type_id = 6
  AND p.like_count >= 1
  AND (:backfill OR p.user_id IN (:user_ids))
GROUP BY pa.user_id
HAVING COUNT(*) >= 1

実際、これはフラグが立てられた投稿内のリンクであり、PMではないと思います。少し調整が必要かもしれません。

p.id = pa.related_post_id の結合を少し変更すると、うまくいくと思います。:+1:

HAVING は、1つ以上のシルバーおよびゴールドバージョンを付与したい場合にのみ必要だと思います。
