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: logs_controller.rb
    path of file: ./repos/SlideHub/app/controllers/admin
    
    the code of the file until where you have to start completion: module Admin
  class LogsController < Admin::BaseController
    before_action :retrieve

    def index; end

    def show
      @path = params[:path]
      @result = []
      return redirect_to admin_logs_index_path, notice: t(:no_logs) unless @files.include?(@path)

      require 'io'
      require 'log_util'
      File.open(@path) do |io|
        io.tail(300).each do |line|
    
    
    def index; end

    def show
      @path = params[:path]
      @result = []
      return redirect_to admin_logs_index_path, notice: t(:no_logs) unless @files.include?(@path)

      require 'io'
      require 'log_util'
      File.open(@path) do |io|
        io.tail(300).each do |line|
          @result.push SlideHub::LogUtil.escape_to_html(line)
        end
      end
    end

    def download
      path = params[:path]
      return redirect_to admin_logs_index_path, notice: t(:no_logs) unless @files.include?(path)

      stat = File.stat(path)
      send_file(path, filename: File.basename(path), length: stat.size)
    end

    private

      def retrieve
        path = Rails.root.join('log', '*')
        @files = Dir.glob(path)
      end
  end
