# create a file in config/initializers, e.g. add_abilities_to_spree.rb,
# with the following content:

Spree::Ability.register_ability MyAppAbility

# create a file under app/models (or lib/) to define your abilities (in
# this example I protect only the HostAppCoolPage model):

class MyAppAbility
  include CanCan::Ability

  def initialize(user)
