Ruby script to deactivate or add users to database table I have a Ruby script meant for some basic database tasks, such as add a user and deactivate a user.  The end user can load up the script and follow the basic path of "Do I want to add a user?", or "Do I want to deactivate a user?". They have the option to retreat back to the main menu if needed.

The script works just fine, but being new to Ruby, I am starting to sense I have made things overly complicated and some simple refactoring could make the code much cleaner.  I am also interested to hear any other feedback.

  require 'yaml'

  config = YAML.load_file('config.yml')  ## Loads in the config file with databases eligible for selection

  puts 'Loading configured Databases'

  config.each do |k, v|
    puts " #{k}, #{v}"
  end

  def path  # Method to create a reusable menu
    puts "Press 1 to add a new user\nPress 2 to mark a user as active or inactive \nPress 3 to Exit"

    path = gets.chomp.to_i

    if path == 3
      puts 'Exiting...'
      exit
    else
      path_switch(path)
    end
  end

    def path_switch(path_var)
      config = YAML.load_file('config.yml')  ## Loads in the config file with databases eligible for selection
      path = path_var
      rds = ''
      table = ''
      choicelen = config.length
    case path
      when 1
        puts 'Select the numeric ID of the ICE installation to add the user to\n Enter 0 to go back'
        config.each do |k, v|
          puts "#{v['id']}: #{k}"
        end
          choice_client_ice = gets.chomp.to_i
           if choice_client_ice &gt; choicelen
             puts 'error, not a valid selection'

Some high level advice:


Fix your indendation.  For example, the indentation is randomly increased on this line: choice_client_ice = gets.chomp.to_i.  I mention this only because there is a lot of deep nesting here, which is confusing enough without incorrect indentation. Which brings me to...
Try to rewrite this entire thing, allowing yourself only 1 level of indentation (or 2, at most).  This will force you to separate high level logic and implementation detail, by pulling implementation out into its own functions.
Try to rewrite it, keeping your program logic and "views" separate.  All the puts statements are "view" code -- they are to your command line app what html files are to web apps.  Think about writing functions with names like main_menu_selection, which do nothing but present the user with his choices, get his selection, and return it.
