Html 调用render时未加载Ruby布局

我正在使用模型验证，我想用register.html.erb页面加载默认布局。但是，当我只使用渲染

寄存器时，我的布局没有加载。请检查-

#users_controller.rb
def create
    @user = User.new(create_user_params)
    #raise @user.inspect
    respond_to do |format|
      if @user.save
        format.html { redirect_to :success, notice: 'Registration was successfully created.' }
        format.json { render :success, status: :created, location: @users }
      else
        format.html { render :register }
        format.json { render json: @users.errors, status: :unprocessable_entity }
      end
    end
  end

下面是
format.html{render:register}
我已成功获取验证错误消息。但是设计只缺少加载
register.html.erb
。完整页面未随布局一起提供。如果我使用
重定向\u至：注册
而不是
呈现：注册
我的页面成功重定向至注册页面，但我的错误消息未显示

我将如何显示我的验证错误和设计

class ApplicationController
您所说的“完整设计”是什么意思？缺少什么部分？完整的设计意味着我在
application.html.erb
layout中编写了css和js。但是我的布局没有加载。所以所有的css和js都丢失了。只有
register.html.erb
页面表单设计即将推出。@Chinu您的控制器是否继承
ApplicationController
？是我的控制器继承请回答：
