Devise 3.11, Rails 4. Get list of signed in users

When I am in my admin interface I'd like to see what users are signed in.

like this

  • User name, Signed in ?
  • Elvis, no
  • Chet Baker, no
  • Michael Jackson, no
  • Herbie Hancock, Yes
  • Justin Bieber, Yes

    • Using devise, I added the trackable feature

    in my migration 

    t.integer  :sign_in_count, :default => 0
t.datetime :current_sign_in_at
t.datetime :last_sign_in_at
t.string   :current_sign_in_ip
t.string   :last_sign_in_ip

    Problem is that if a user signs out the :current_sign_in_at and :current_sign_in_ip is not set to nil.

    I added this to my sessions_controller.rb

    def destroy
    current_user.current_sign_in_at = nil
    current_user.save
    signed_out = (Devise.sign_out_all_scopes ? sign_out : sign_out(current_user))
    set_flash_message :notice, :signed_out if signed_out
    redirect_to root_url
  end

    Now the current_sign_in_at is updated when the users sign out.

    Then I added the :timeoutable mpdule. When the sessions time out the current_sign_in_at not is updated.

    After all this hacking, I begin to wounder: Does not devise have a more elegant way of doing this?

    This is a bit hard.

    If the user signs out it is easy to nil out the ':current_sign_in_at'

    It's a bit harder when the session times out. When the user tries to enter after the time out devise does a warden.logout on the session and the user have to sign in again. If the user does not do anything or just closes the browser he/she are still signed in, as far as the server knows.

    To make this work we'd have to: A: Ask the clients browser for env['warden'].session.last_request_at all the time B: Create the session table with 'rake db:sessions:create' and put this in the session_store.rb initializer. 

    Squadlink::Application.config.session_store :active_record_store

    Then the sessions will be on the server for better control.

    For now i did this

    config/initializers/warden.rb

    Warden::Manager.before_logout do |record, warden, opts|
  if record.respond_to?(:logout_stamp!)
    record.logout_stamp!
  end
end

    models/user.rb

    def logout_stamp!
  self.current_sign_in_at = nil
  self.current_sign_in_ip = nil
  self.save
end

    And removed the 

    current_user.current_sign_in_at = nil
current_user.save

    lines form the sessions_controller destroy action.

    If the user signs out or gets signed out the 'current_sign_in_at' and 'current_sign_in_ip' are set to nil.

    Hope it helps someone.
