  # CanCanCan will automatically instantiate an Ability object with every
  # request. It will just expect that you have a method in your controller named
  # `current_user` which we do.
  def initialize(user)

    # it's highly recommend that you start with this line because `user` will
    # be nil if the user is not signed in so it would be ncie to have `user`
    # variable point to a new User object if it's nil so we can easily compare
    user ||= User.new

    # :manage refers to doing any action on the question object: :read, :delete
    # :edit, :update...etc
    can :manage, Question do |q|
      q.user == user
    end

    can :delete, Answer do |a|

    # if you want to be more specific you could define individual actions
    # can :edit, Question do |q|
    #   # ..

    #

    #   else

    #   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
