  include CanCan::Ability

  def initialize(user)
    user ||= User.new # guest user (not logged in)
    if user.admin?
      can :manage, :all
    else

you can write a method in ApplicationController like:

def require_admin
 current_user.admin?
end

then in your desired controller, you can use

before_action :require_admin, except: :show

I guess I gave you an idea and you should improvise it.
