Oh, sorry, I didn’t look at the context the query was being used in. You’ve currently got something like this:
WHERE category_id = (
SELECT id FROM categories
WHERE name IN ('OAuth', 'Developers')
)
Since the inner query is returning multiple rows, you need to change the outer WHERE clause to:
WHERE category_id IN (
SELECT id FROM categories
WHERE name IN ('OAuth', 'Developers')
)Success, thanks!
Would this be too much to run whenever a user acts on a post?
Could it easily be modified to award a badge when a post is ‘marked as a solution’ rather than liked?
edit: Actually, that’s giving me: ‘Contract violation: Query triggers on posts, but does not reference the ‘:post_ids’ array’
I can probably live with update daily though. ¯_(ツ)_/¯
@sam, we’re looking on implementing a similar badge over at Stonehearth. Can you share the current SQL used, as yours is 2+ years old, and there are numerous different versions in this topic?

I was just awarded the Tester badge, but I only have 2 Bug Reporter badges. The text of the Tester badge says this:
Reported 10 bugs that were liked by the Discourse team
I just checked: One of my bug reports has 10 
likes, but not even those are exclusively by Discourse Team members.
Something seems to be wrong with the badge… 
There are several old bugs that were deleted as not of future historical interest, but the total isn’t 10.
Thanks, I fixed the queries and updated @sam’s post.
@sam أين يجب أن أقوم بتشغيل هذا الرمز للحصول على هذه الشارة المعينة، وهل يجب علينا إنشاء فئة لتقرير الأخطاء؟
SELECT p.user_id, MIN(p.created_at) granted_at
FROM posts p
JOIN topics t ON t.id = p.topic_id
WHERE t.category_id = (SELECT id FROM categories WHERE name ILIKE 'bug')
AND p.post_number = 1
AND EXISTS (
SELECT 1
FROM post_actions pa
WHERE pa.post_id = p.id
AND pa.post_action_type_id = (SELECT id FROM post_action_types WHERE name_key = 'like')
AND pa.user_id IN (SELECT user_id FROM group_users WHERE group_id = (SELECT id FROM groups WHERE name ILIKE 'team'))
)
GROUP BY p.user_id
HAVING COUNT(*) >= 20
هذه الشارة خاصة بـ meta.
آه، لا يمكننا استخدامه في الخطاب؟
نعم، يمكننا ذلك. ولكن يجب تغيير أسماء الفئات والمجموعات إلى أسماء صالحة.
مفهوم، مثل إخفاء خدعة الفئة، ولكن هنا لم أتعرف على مكان تشغيل كود sam؛ من لوحة المسؤول أو داخل حاوية rails c؟
قد لا تجد مكان إضافة الرمز لأن تحرير SQL للشارات معطل افتراضيًا. انظر هنا:
لذلك أعتقد أن العملية ستكون:
ثم إذا لم تكن قد فعلت ذلك بالفعل، بناءً على القيم الموجودة في SQL الذي نشرته:
قد يكون هذا تحسينًا للاستعلام
