You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: controller.rb
    path of file: ./repos/ahoy/lib/ahoy
    
    the code of the file until where you have to start completion: module Ahoy
  module Controller
    def self.included(base)
      if base.respond_to?(:helper_method)
        base.helper_method :current_visit
        base.helper_method :ahoy
      end
      base.before_action :tra
    
    def track_ahoy_visit
      defer = Ahoy.server_side_visits != true

      if defer && !Ahoy.cookies?
        # avoid calling new_visit?, which triggers a database call
      elsif !Ahoy.cookies? && ahoy.exclude?
        # avoid calling new_visit?, which triggers a database call
        # may or may not be a new visit
        Ahoy.log("Request excluded")
      elsif ahoy.new_visit?
        ahoy.track_visit(defer: defer)
      end
