# 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
#
