你的控制器中的东西？

我试图在Rails上教一个课程,我想从他们生成一个脚手架开始,但是所有的json格式化都比它需要的要复杂得多.如果他们可以生成一个创建一个这样的控制器的脚手架,我会更快乐：

class ThingsController < ApplicationController

  def index
    @things = Thing.all
  end

  def show
    @thing = Thing.find(params[:id])
  end

  def new
    @thing = Thing.new
  end

  def edit
    @thing = Thing.find(params[:id])
  end

  def create
    @thing = Thing.new(params[:thing])
      if @thing.save
        redirect_to @thing,notice: 'Thing was successfully created.'
      else
        render: "new" 
      end
    end
  end

  def update
    @thing = Thing.find(params[:id])
      if @thing.update_attributes(params[:thing])
        redirect_to @thing,notice: 'Thing was successfully updated.'
      else
        render: "edit" 
      end
    end
  end

  def destroy
    @thing = Thing.find(params[:id])
    @thing.destroy
    redirect_to things_url
  end
end
