Does anyone know a safe way to set the notification levels for all users on a topic to a single value? I’m guessing that it would be something in the Rails console.
I want to set all the users on a topic to “Mute” or “Normal” instead of “Watching” or “Tracking.”
The goal is to reduce activity on a big topic in a complex moderation situation.

What about enabling Slow Mode? Would not it help to reduce the activity? 🤔

This situation is complex and I don’t want a visual indication that triggers a public discussion about it that might take up hours of moderation time. (I’m already completely overwhelmed.) The ideal outcome is that people just aren’t reminded that the topic exists.

I would unlist the topic. Then it is hidden from the forum so probably most users won’t see it there anymore. But when they have a link to that topic (e.g., because they received a notification), they can still open the topic.

Though, just to note, if they’re Watching it then they’d still get notifications when it’s Unlisted.

I think you can now use the `/t/TOPIC_ID/notifications` endpoint to set the notification level for a user on a specific topic, if that’s a more appealing choice than the rails console?

But for the rails console I think it would be this: (remember to take a backup just in case before trying to change things in rails ⚠)
```plaintext
TopicUser.where(topic_id: TOPIC_ID).update(notification_level: 1)
```
(1 is normal, 0 is mute)
That would change the topic level ones, but there may be category and tag level ones which may still affect who gets a ping for new activity.
And a little [data explorer](https://meta.discourse.org/t/32566?silent=true) query to check the levels for users on a topic if that’s useful too:
```sql
SELECT
topic_id,
user_id,
notification_level
FROM topic_users
WHERE topic_id = TOPIC_ID
```

Thanks for the detailed response. I’ll try the API tomorrow.
