class CreateNotificationsWorker
  include Sidekiq::Worker
  def perform
    users = User.all
    users.each do |user|
      tasks = user.tasks
      tasks.each do |task|
        if task.deadline && task.status == 'pending' && task.notified_user == false
          @notification = Notification.create!(user_id: user.id, task_id: task.id)
          task.notified_user = true
          task.save!
        end
      end
    end
  end
end

Task.pending => Great idea! I had completely forgotten about these methods associated with enums.
.where.not => Sweet!
find_each=> Sonia talked to me about it yesterday. Really cool way to reduce the load on memory.

Thanks, @benoittgt for all these ameliorations.

I don't use any bug library (not that I'm aware of anyway). Which one would you suggest I should start with?

We use airbrake an are quite happy about it. But honeybadger seems good too.
