我的问题表有以下列：id、question、answer、created_at、updated_at、sender_id、receiver_id。

最新的问题应该出现在顶部。

问题控制器：

 def index
    @questions = Question.all
    respond_with(@questions)
end

def show
  @question = Question.find(params[:id])
  respond_with(@questions)
end

答案控制器：

  def new
    @question = Question.find(params[:question_id])
  end

  def create
    @question = Question.find(params[:question_id])
    if @question.update_attributes(params[:question])
      redirect_to questions_path
    else
      render :new
    end

路线：

  resources :questions do
    resources :answers, only: [:new, :create]
  end
