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: railtie.rb
    path of file: ./repos/chewy/lib/chewy
    
    the code of the file until where you have to start completion: module Chewy
  class Railtie < Rails::Railtie
    def self.all_engines
      Rails::Engine.subclasses.map(&:instance) + [Rails.application]
    end

    class RequestStrategy
      def initialize(app)
        @app = app
      end

      def call(env)
        # 
    
      def call(env)
        # For Rails applications in `api_only` mode, the `assets` config isn't present
        if Rails.application.config.respond_to?(:assets) && env['PATH_INFO'].start_with?(Rails.application.config.assets.prefix)
          @app.call(env)
        else
          if Chewy.logger && @request_strategy != Chewy.request_strategy
            Chewy.logger.info("Chewy request strategy is `#{Chewy.request_strategy}`")
          end
