Question

我是Rails的新手，如果有人能帮助我，我会很感激。我正在玩这个测验应用程序，我有一个问题和选择控制器和模型。我只有一个课程控制器及其各自的观点。我的问题出于某种原因，无论我创建了多少问题，它们都没有循环，它始终显示ID = 1的问题。在过去的两天里，我一直试图弄清楚这一点，没有运气，任何指示或提示，都欢迎。提前谢谢。

class LessonsController < ApplicationController

 def index
 end

 def start
 total = params[:number].to_i
 all = Question.where(:all).map {|x| x.id}
 session[:questions] = all.sort_by{rand}[0..(total-1)]

 session[:total]   = total
 session[:current] = 0
 session[:correct] = 0

 redirect_to :action => "question"
  end

 def question
 @current = session[:current]
 @total   = session[:total]

 if @current >= @total
    redirect_to :action => "end"
    return
  end 

  @question = Question.find_by(session[:questions][@current])
  @choices = @question.choices.sort_by{rand}

 session[:question] = @question
 session[:choices] = @choices

 end

 def answer

 @question = session[:questions]
 @current = session[:current]
 @total   = session[:total]

 @choiceid = params[:choice]

 @question = session[:question]
 @choices  = session[:choices]

 @choice = @choiceid ? Choice.find(@choiceid) : nil
 if @choice and @choice.correct
    @correct = true
    session[:correct] += 1
  else
    @correct = false
  end

  session[:current] += 1
end

 def end
 @correct = session[:correct]
 @total   = session[:total]

 @score = @correct * 100 / @total
 end



 end
