的Rails：構建多雛型

我有救一個問題，在數據庫中的5個答案，但我不知道我怎麼可以保存答案一種形式，這是我的表格：的Rails：構建多雛型

<%= form_for([:admin, @question]) do |f| %> 

... 

<%= f.fields_for :answers do |builder| %> 
    <%= builder.label :answer, "Risposta", :class => "v-align" %> 
    <%= builder.text_field :answer, :rows => 2 %> 

    <%= builder.label :correct, "Corretta", :class => "v-align" %> 
    <%= builder.check_box :correct %> 
<% end %> 

... 

<% end %>

我的模型：

class Question < ActiveRecord::Base 
    has_many :answers 
    accepts_nested_attributes_for :answers, :reject_if => lambda { |a| a[:content].blank? }, :allow_destroy => true 
    attr_accessible :answers_attributes, :quiz_id, :question, :sort_order, :point_value, :number_correct, :explanation 
end 

class Answer < ActiveRecord::Base 
    belongs_to :question 
    attr_accessible :question_id, :answer, :correct, :sort_order 
end

而我的「問題」控制器：

def new 
    @question = Question.new 
    5.times { @question.answers.build } 

    respond_to do |format| 
     format.html # new.html.erb 
     format.json { render :json => @question } 
    end 
end 

def create 
    @question = Question.new(params[:question]) 

    respond_to do |format| 
     if @question.save 
      format.html { redirect_to admin_question_path(@question), :notice => 'Test was successfully created.' } 
      format.json { render :json => @question, :status => :created, :location => @question } 
     else 
      format.html { render :action => "new" } 
      format.json { render :json => @question.errors, :status => :unprocessable_entity } 
     end 
    end 
end

我應該做些什麼來保存在數據庫中的問題和答案？

謝謝！
