如何在视图中显示最新内容

Question

我的问题表包含以下列：id，question，answer，created_at，updated_at，sender_id，recipient_id。

最新问题应该出现在最上面。

问题主持人：

 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

Answer 1

@questions = Question.order("created_at DESC")
