tracking all online users in Volt

Question

I'm trying to make a record of all the users which are currently online.

Here's what I've tried:

• In my "main_controller":

  channel.on('connect') { puts "ON"; store._online_users << Volt.current_user.to_h } channel.on('disconnect') { puts "OFF"; store._online_users.delete(Volt.current_user.to_h) }

In my "main.html":

  {{store._online_users.each do |user| }}
    {{user.to_h}} <br>
  {{end}}

The problem is, at some point when testing this I ended up with around a dozen entries in the store._online_users list. I want to delete them all, but I can't get it to work. I've tried:

• store._online_users.clear has no effect
• store._online_users.each(&:destroy) no effect
• store._online_users = [] no effect

Edit

So, since originally posting this question, I've realized that Volt.current_user is nil unless somebody has logged in through the auth system.

There's still the problem of undeletable records in my store._online_users, so I'm trying a different key.

I tried the following, but store._current_users always remains empty:

  channel.on('connect') {
    Volt.current_user.then { |user|
      unless user.nil?
        store._current_users << user
      end
    }
  }
  channel.on('disconnect') {
    Volt.current_user.then { |user|
      unless user.nil?
        store._current_users.delete(user)
      end
    }
  }

How would i make a ModelArray which contains all currently online users?
