Question

我一直在寻找，但是找不到或者非常清楚该做什么，我确信它非常简单我只是对Ruby和Web应用程序很新，这个是在Sinatra中简单。我想将form_for变量以及用户输入的内容传递到下一个结果页面的输入中，这样我就可以看到他们是否正确地输入了答案但是我不知道怎么做，我想我知道如何使用# web.rb require 'sinatra' def create_table(number) possibles = [1,2,3,4,5,6,7,8,9,10,11,12] int_set = possibles.shuffle result = [] @answer_list = [] while int_set.length > 0 random_int = int_set[0] string = (number.to_s + " x " + random_int.to_s) int_set.delete(random_int) if (random_int.to_s).length == 1 string += "   = ______" else string += " = ______" end result << string @answer_list << random_int.to_i * number.to_i end return result end get '/' do @greeting = "Hi! Enter a number to generate a quick test." erb :index end post '/results' do erb :results @multiplication_table end post '/' do @multiplication_table = create_table(params[:int_to_generate]) @answers = @answer_list erb :multiplication_table_page end执行此操作，但我不知道如何使用for循环执行此操作。
