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 # # See the wiki for details: https://github.com/ryanb/cancan/wiki/Defining-Abilities end end
