Badge granted to our staff members that have read the guidelines placed in our hidden staff category

We’d like to have a badge granted to our staff members that have read the guidelines placed in our hidden staff category.

This would (presumably) be very similar to the “Read Guidelines” badge:

SELECT user_id, read_faq granted_at
FROM user_stats
WHERE read_faq IS NOT NULL AND (user_id IN (:user_ids) OR :backfill)

With a modification to allow us to specify specific topics or post, and add more in the future.

Could anyone help with that?

Unlikely because read_faq is ‘special’ and not reprogrammable or extendable. The following may do what you’re after however:

SELECT user_id, CURRENT_TIMESTAMP AS granted_at
FROM post_timings
WHERE topic_id = /* put the topic id of your guidelines here */
AND post_number = /* this will probably be 1 since I suspect it's the only thing there */
AND msecs > 10000 /* they've looked at it for more than 10 seconds */

Thanks very much @PJH!

Test it first… I’m not sure how/when the msecs column gets updated.

I’d also recommend running it -at most- daily, with no revocation.

Works, thanks! Though this probably isn’t the ideal solution, n the interest of giving back to the community, here’s our multipost version.

    SELECT post_timings.user_id, CURRENT_TIMESTAMP AS granted_at    
FROM post_timings
JOIN (
     SELECT post_timings.user_id, CURRENT_TIMESTAMP AS granted_at      
     FROM post_timings
     JOIN (
           SELECT post_timings.user_id, CURRENT_TIMESTAMP AS granted_at
           FROM post_timings
           WHERE topic_id = 206 
           AND post_number = 1
           AND msecs > 10000 
          ) a ON a.user_id = post_timings.user_id
     WHERE topic_id = 1066
     AND post_number = 1
     AND msecs > 10000
    ) b ON b.user_id = post_timings.user_id
WHERE topic_id = 1043
AND post_number = 1
AND msecs > 10000

How about:

SELECT count(*), user_id, CURRENT_TIMESTAMP AS granted_at
FROM post_timings
WHERE
( topic_id = 206 AND post_number = 1 AND msecs > 10000) OR
( topic_id = 1066 AND post_number = 1 AND msecs > 10000) OR
( topic_id = 1043 AND post_number = 1 AND msecs > 10000)
GROUP BY user_id
HAVING count(*) = 3

Edit: Changed since it was pointed out to me that the original wouldn’t have worked.

Couldn’t this be rewritten as:

SELECT count(*), user_id, CURRENT_TIMESTAMP AS granted_at
FROM post_timings
WHERE post_number = 1
AND msecs > 10000
AND ( topic_id = 206 OR topic_id = 1066 OR topic_id = 1043 )
GROUP BY user_id
HAVING count(*) = 3

I’m no SQL expert, just seems like it should be possible given the duplication in the original query.

Presuming 10 seconds is sufficient for all the posts, and the first post in each topic is the one being targeted, yes…

9

Yeah, not sure what a good read time is, but 10 seconds seems okay.

I would also assume the first post is the focus.

Also couldn’t this be simplified a bit more? (Again naive SQL assumptions)

SELECT count(*), user_id, CURRENT_TIMESTAMP AS granted_at
FROM post_timings
WHERE post_number = 1
AND msecs > 10000
AND topic_id IN ( 206, 1066, 1043 )
GROUP BY user_id
HAVING count(*) = 3

All are pretty great, though this one strikes me as the most extensible.

But this is just code golf now, right?

I had the same thought myself…

I think it boils down to maintainable queries. Duplication is a pain to work around.
