如果您的论坛安装了数据探索器插件(Data Explorer Plugin),您就可以编写 SQL 查询语句从 Discourse 数据库中获取这些信息。此查询尝试获取主题的 ID 和标题,以及主题中最后一篇帖子的用户 ID。它只选择最后一篇帖子是由“clients”组中的用户发布的那些主题。
这只是一个示例。
SELECT
t.id AS topic_id,
t.title AS topic_title,
(SELECT user_id FROM posts WHERE topic_id = t.id ORDER BY created_at DESC LIMIT 1) AS last_post_user_id
FROM
topics t
JOIN
posts p ON p.topic_id = t.id
JOIN
group_users gu ON gu.user_id = p.user_id
JOIN
groups g ON g.id = gu.group_id
WHERE
g.name = 'clients'
GROUP BY
t.id
HAVING
MAX(p.user_id) = last_post_user_id
ORDER BY
MAX(p.created_at) DESC
