用户页面指标

数据与报告
8

您说得对，user_stats 表是一个静态表，总结了用户加入 Discourse 以来的终生指标。

相反，要按日期过滤指标，例如 posts_read_count 和 days_visited，我们将需要使用 user_visits 数据库表来获取 posts。我们还需要使用 topic_views 表来按日期过滤 topics_entered 指标。

您观察到的差异源于使用 user_stats 表而不是 user_visits 和 topic_views 等其他表来按日期过滤这些统计数据。

为解决此问题，我们可以更新查询以使用这些数据库表：

以下是查询的更新版本：

用户页面指标

-- [params]
-- date :start_date = 2020-01-01
-- date :end_date = 2026-01-01

WITH likes_received AS (
    SELECT
        ua.user_id AS user_id,
        COUNT(*) AS likes_received
    FROM
        user_actions ua
    WHERE
        ua.action_type = 2
        AND ua.created_at BETWEEN :start_date AND :end_date
    GROUP BY
        ua.user_id
),
likes_given AS (
    SELECT
        ua.acting_user_id AS user_id,
        COUNT(*) AS likes_given
    FROM
        user_actions ua
    WHERE
        ua.action_type = 1
        AND ua.created_at BETWEEN :start_date AND :end_date
    GROUP BY
        ua.acting_user_id
),
user_metrics AS (
    SELECT
        tv.user_id,
        COUNT(DISTINCT tv.topic_id) AS topics_viewed
    FROM
        topic_views tv
    WHERE
        tv.viewed_at BETWEEN :start_date AND :end_date
    GROUP BY
        tv.user_id
),

    SELECT
        uv.user_id,
        COUNT(DISTINCT uv.visited_at) AS days_visited,
        SUM(uv.posts_read) AS posts_read
    FROM
        user_visits uv
    WHERE
        uv.visited_at BETWEEN :start_date AND :end_date
    GROUP BY
        uv.user_id
),
solutions AS (
    SELECT
        ua.acting_user_id AS user_id,
        COUNT(*) AS solutions
    FROM
        user_actions ua
    WHERE
        ua.action_type = 15
        AND ua.created_at BETWEEN :start_date AND :end_date
    GROUP BY
        ua.acting_user_id
),
cheers AS (
    SELECT
        gs.user_id,
        SUM(gs.score) AS cheers
    FROM
        gamification_scores gs
    WHERE
        gs.date BETWEEN :start_date AND :end_date
    GROUP BY
        gs.user_id
)

SELECT
    u.id AS user_id,
    COALESCE(lr.likes_received, 0) AS likes_received,
    COALESCE(lg.likes_given, 0) AS likes_given,
    COALESCE(um.topics_viewed, 0) AS topics_viewed,
    COALESCE(dp.days_visited, 0) AS days_visited,
    COALESCE(dp.posts_read, 0) AS posts_read,
    COALESCE(sol.solutions, 0) AS solutions,
    COALESCE(ch.cheers, 0) AS cheers
FROM
    users u
LEFT JOIN
    likes_received lr ON u.id = lr.user_id
LEFT JOIN
    likes_given lg ON u.id = lg.user_id
LEFT JOIN
    user_metrics um ON u.id = um.user_id
LEFT JOIN
    days_and_posts dp ON u.id = dp.user_id
LEFT JOIN
    solutions sol ON u.id = sol.user_id
LEFT JOIN
    cheers ch ON u.id = ch.user_id
ORDER BY
    u.id

请注意，通过此方法，user_visits 表中的 posts_read 数据有一个重要区别——它不计算用户自己发布的帖子，而 user_stats 表中的数据确实包含用户自己撰写的帖子，因此您在此查询和用户页面之间仍可能发现这两个统计数据之间存在差异。
