Hay all! I have question-answer base.. like quiz, yeah? yes! So i need to do this way... my project without registration so this way i need token.. user can answer on my question only once.. How can i do this? Iand i can give him link, and link should be like : localhost:3000/token .. he gets on this link, answer and click go and that's all. If he want to get on this page once again he will get message something like "Sorry bro you already passed quiz".

#answer_controller.rb class AnsweController < ApplicationController

  layout "default"

  $all_questions_archive = Question.count('id')   $all_questions_active = Question.find(:all,:conditions=>"enabled=1").count

  def create

  @w1 = rand(9999999)   @w = Digest::SHA1.hexdigest(@w1.to_s)

        @answers=Hash.new   questions = Question.find(:all,:conditions=>"enabled=1")   questions.each do |question|             if params["answer_"+question.id.to_s]      @answers[question.id]=params["answer_"+question.id.to_s]          if !Answer.create(:question_id=>question.id,:token=>@w,:text=>params["answer_"+question.id.to_s])       flash[:error]="Can`t create answer!"      end             end   end   if !flash[:error]           redirect_to :action=>"pass"            return false   end

  end

  def index

     @answers=Hash.new      @questions = Question.find(:all,:conditions=>"enabled=1")

  end

  def pass   flash[:notice]="<span id='ty'>Thank you for your answers!</span>"         render :text=>"", :layout=>"ty"   end
