How to use devise helpers in a rake task?

My task will do the following:

I want this task to be executed every hour (it will be scheduled with Heroku Scheduler add-on)

The problem here is that you cannot use user_signed_in? or current_user in any rake file you write. In addition, I can not pass any of these values as parameters because It will be called from the Heroku Scheduler, dashboard.

Some of my code here:

lib/tasks/scheduler.rake

task :send_notification => :environment do
  if user_signed_in?
    puts "No need to email"
  else
    puts "Sending email"
    u=User.find(132)   #get an admin user
    ModelMailer.time_notification(u).deliver
  end
end

The error:

rake aborted!
NoMethodError: undefined method `user_signed_in?' for main:Object

Thanks in advance!

Devise in its default configuration does not allow you to track which users are online and offline. The helpers current_user and user_signed_in? pertain to the current session and are only valid during a user's request. Since there is no request in a rake task, they aren't useful.

You could potentially add a column to your database to track whether users are signed in or signed out, but this functionality isn't present in devise.
