# File 'lib/generators/cancan/ability/templates/ability.rb', line 4

def initialize(user)
  # Define abilities for the passed in user here. For example:
  #
  #   user ||= User.new # guest user (not logged in)
  #   if user.admin?
  #     can :manage, :all
  #   else
  #     can :read, :all
  #   end
  #
  # The first argument to `can` is the action you are giving the user 
  # permission to do.
  # If you pass :manage it will apply to every action. Other common actions
  # here are :read, :create, :update and :destroy.
  #
  # The second argument is the resource the user can perform the action on. 
  # If you pass :all it will apply to every resource. Otherwise pass a Ruby
  # class of the resource.
  #
  # The third argument is an optional hash of conditions to further filter the
  # objects.
  # For example, here the user can only update published articles.
  #
  #   can :update, Article, :published => true
  #
