Badges for posting

[PJH]

Since there deliberately isn’t the concept of achievements for posting, I’ve managed to implement it on ours, since we had it on our old forums and some were complain about the lack thereof.

Generic version:

SELECT user_id, 0 post_id, current_timestamp granted_at 
FROM badge_posts  
WHERE (:backfill OR user_id IN (:user_ids) OR 0 NOT IN (:post_ids) )
GROUP BY user_id 
HAVING count(*) > 1000

Change the 1000 for whatever post limit you’re after. I’ve themed ours (due to the nature of our board) on powers of 2.

Note that this will (should) only count posts that are public (not in categories that are restricted or private messages) or otherwise unrestricted (checkbox on edit category ignoring badges)

Additionally, for our board I’ve had to exclude certain topics due to the nature of my charges:

SELECT user_id, 0 post_id, current_timestamp granted_at 
FROM badge_posts  
WHERE topic_id NOT IN (
   [elided]
) AND topic_id NOT IN (
   [elided]
) AND  (:backfill OR user_id IN (:user_ids) OR 0 NOT IN (:post_ids) )
GROUP BY user_id 
HAVING count(*) >= 2048

Edit: There was a problem with my queries - post_id is apparently required when this is triggered on post-related triggers.

And

Create Triggered Custom Badge Queries

This feature is disabled by default, to enable it follow this guide [image] When defining badges there is this beguiling box “Trigger” with the options: Update daily When a user acts on a post When a user edits or creates a post When a user changes trust level When a user is edited or created The trigger forces badges to run at an interval that is more frequent than daily. We use these triggers in our badges. They ensure users are notified of new badges closer to the time the …

Edit 2: Added :backfill

I think I have the correct trigger condition here, actually:

    :backfill OR
    user_id IN (
        SELECT trigger_post.user_id FROM posts trigger_post WHERE trigger_post.id IN (:post_ids)
    )

You get the user id list from the list of triggered posts and filter on that.

Thanks. This is very helpful. I am also thinking about encouraging users to initiate discussions. I am messing around your query to count original posts with p.post_number = 1

SELECT user_id, 0 post_id, current_timestamp granted_at 
FROM badge_posts  
WHERE (:backfill OR user_id IN (:user_ids) OR 0 NOT IN (:post_ids) )
GROUP BY user_id 
HAVING count(*) > 1000

Я только что наткнулся на эту небольшую находку. Я хотел создать собственные пользовательские запросы для значков, учитывающие количество постов в конкретных категориях. Как можно модифицировать этот запрос, чтобы добавить условие для конкретных идентификаторов категорий, чтобы учитывались только посты в определённой категории?

Some common badge queries

Enabling Badge SQL entails security and performance risks so it is not available by default. For more information, see: Enable Badge SQL Here are some common badge queries which you can use to create your own awesome badge! Grant a badge if user has created at least one topic in the “foo”* category *(“foo” is the category name, not the category slug) SELECT p.user_id, min(p.created_at) granted_at, MIN(p.id) post_id FROM badge_posts p JOIN topics t ON t.id = p.topic_id WHERE cate…

Это должно быть модификацией первого запроса здесь, где значки выдаются за создание тем в определённой категории. Разница в том, что мы выдаём значки на основе количества постов в конкретной категории.

Общая версия:

SELECT user_id, 0 post_id, current_timestamp granted_at 
FROM badge_posts  
WHERE (:backfill OR user_id IN (:user_ids) OR 0 NOT IN (:post_ids) )
GROUP BY user_id 
HAVING count(*) > 1000

При предварительном просмотре запроса на получение значков возникает следующая ошибка:

Произошла ошибка при выполнении запроса. Есть идеи, как её исправить?

Нарушение контракта:
Запрос срабатывает на сообщениях, но ссылается на массив ':user_ids'
