Rails 设计身份验证，排除登录屏幕布局

我正在使用设备身份验证。我希望登录页面出现在空白页面上。所以， render ' layouts/navigation '.... <% = Render ' layouts/Topnavbar '%>..... <% = Render ' layouts/footer '% > 我不想看到这个。我怎样才能做到这一点？

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception

  ##    milia defines a default max_tenants, invalid_tenant exception 
   handling
  ##    but you can override these if you wish to handle directly
  rescue_from ::Milia::Control::MaxTenantExceeded, :with => :max_tenants
  rescue_from ::Milia::Control::InvalidTenantAccess, :with => :invalid_tenant


  before_action :authenticate_tenant!
end

应用程序.html.erb

<div id="wrapper">    
  <!-- Navigation -->
  <%= render 'layouts/navigation' %>

  <!-- Page wraper -->
  <div id="page-wrapper" class="gray-bg">

      <!-- Page wrapper -->
      <%= render 'layouts/topnavbar' %>

      <!-- Main view  -->
      <p class="notice"><%= notice %></p>
      <%= yield %>

      <!-- Footer -->
      <%= render 'layouts/footer' %>

  </div>
  <!-- End page wrapper-->    

class UsersController < ApplicationController
before_action :authenticate_user!

def index                   
    @users = User.all
end

def show
    @user = User.find(params[:id])
end

def destroy
    user = User.find(params[:id])
    user.destroy
    redirect_to users_path, :notice => "User deleted"
end

def update
    @user = User.find(params[:id])

    if @user.update_attributes(secure_params)
        redirect_to user_path, :success => 'User updated'
    else
        redirect_to user_path :alert => 'Unable to update user'
    end
end

end

我明白......不幸的是它不起作用......我认为Milia gem文件不使用控件。我在路由中使用了 Milia/sessions 而不是 devise/sessions。使用 Milia 成员和用户控件。哪里渲染布局：false 不起作用

resources :members
  get 'home/index'

  root :to => "home#index"


  # *MUST* come *BEFORE* devise's definitions (below)
  as :user do   
    match '/user/confirmation' => 'milia/confirmations#update', :via => :put, :as => :update_user_confirmation
  end


  devise_for :users, :controllers => { 
    :registrations => "milia/registrations",
    :confirmations => "milia/confirmations",
    :sessions => "milia/sessions", 
    :passwords => "milia/passwords", 
  }
