Probably this part of `app/models/post_action.rb` to update counts:

```ruby
    when :like
      # 'like_score' is weighted higher for staff accounts
      score = PostAction.joins(:user)
        .where(post_id: post_id)
        .sum("CASE WHEN users.moderator OR users.admin THEN #{SiteSetting.staff_like_weight} ELSE 1 END")
      Post.where(id: post_id).update_all ["like_count = :count, like_score = :score", count: count, score: score]

```

and maybe I’ll try using this to actually do the “like” which is a kind of `PostAction`:

This is my first time even looking at Ruby code… this will be fun…
