I’ve been looking at this topic as a way of updating the “Watching First Post” field for all the users:

However I can’t work out which model/ column to change. This does not work:
```
UserOption.update_all(watched_first_post_category_ids: '[5,6,7,8]')
```
As `watched_first_post_category_ids` does not exist in the `user_options` table.
I’ve had a [poke around in the Discourse Github code](https://github.com/discourse/discourse/search?q=watched_first_post_category_ids&unscoped_q=watched_first_post_category_ids) but I’m new to Rails & not sure what I should be looking for.
Could someone please give me the correct Rails Console command to change the “Watching First Post” field for all users?

I’m on my phone and can’t test but I think just remove the quotes from around the array.
