Rails 4.1 filtering by enums

my_cool_model.rb

class MyCoolModel < ActiveRecord::Base {
  enum :status => [:started, :in_progress, :completed]
  
  # What I'd like to work
  scope :not_completed -> { where('status' => [:in_progress, :started]) }

  # Hacky workaround
  scope :not_completed -> { where('status' => MyCoolModel.statuses.values_at(:in_progress, :started)) }
}
