如何存储循环的每个实例？

Question

我有以下方法可以让用户要求饮料最多 6 次。每次他们选择一种饮料时，它可能是一种新的，或者是菜单列表中的同一种饮料。如何在每个循环中记录用户响应？

def display
  menu_list = AlcoholicBeverage.pluck(:cocktail_name)
  puts menu_list
  sleep(0.1)
  puts "So, what's your poison?" "\n" 
end

def drink_valid?
  chosen_cocktail = gets.chomp.titleize
  until AlcoholicBeverage.find_by(cocktail_name: chosen_cocktail)
    puts "Sorry please choose something on the list!"
    chosen_cocktail = gets.chomp.titleize
  end

  puts "Mmmm good choice!"
  puts "Now that you've chosen your cocktail, I'll provide you with details on the necessary ingredients,glass and garnishes!"

  glass_type = AlcoholicBeverage.where(cocktail_name: chosen_cocktail).map(&:glass)
  puts "Required : #{glass_type.join.titleize} glass."

  garnish = AlcoholicBeverage.where(cocktail_name: chosen_cocktail).map(&:garnish)
  if garnish.join.titleize == ""
    puts "No garnish needed!"
  else
    puts "Required garnish: #{garnish.join.titleize}"
  end

  preparation = AlcoholicBeverage.where(cocktail_name: chosen_cocktail).pluck("preparation")
  puts "To prepare : #{preparation.join}"
end

def ask
  counter=0
  while counter < 6
    puts "Would you like another drink (yes/no)?"
    new_drink = gets.chomp.strip.titleize

    if new_drink == "Yes" || new_drink == "yes"
      display
      drink_valid?
    else
      puts "I'll give your blood alcohol content level based on the drinks you've had."
    end
    counter +=1
  end
end

您可以通过将用户输入添加到循环外的变量来重复捕获用户输入：

# main.rb
inputs = []
until inputs.size >= 6
  puts "Please input a value or leave blank to exit"
  input = gets.chomp
  break if input == ""
  inputs << input
end

puts "You have input the following: #{inputs.inspect}"

$ ruby main.rb
Please input a value or leave blank to exit
1
Please input a value or leave blank to exit
2
Please input a value or leave blank to exit
3
Please input a value or leave blank to exit
4
Please input a value or leave blank to exit
5
Please input a value or leave blank to exit
6
You have input the following: ["1", "2", "3", "4", "5", "6"]
$ ruby main.rb
Please input a value or leave blank to exit
1
Please input a value or leave blank to exit
2
Please input a value or leave blank to exit

You have input the following: ["1", "2"]
