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: policy_generator.rb
    path of file: ./repos/action_policy/lib/generators/action_policy/policy
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require "rails/generators"

module ActionPolicy
  module Generators
    class PolicyGenera
    
      def run_install_if_needed
        in_root do
          return if File.exist?("app/policies/application_policy.rb")
        end

        generate "action_policy:install"
      end
