我是Ruby on Rails的新手，这是我第一次使用MVC结构，我需要一些帮助，如何将布局链接到视图页面？我正在浏览一些教程，但看起来很复杂，我很困惑。
这是我的观看代码：
<div class="container" id="login">
<div class="row">
<div class="span3"></div>
<div class="span9">
<% resource.remember_me = true %>
<%= form_for(resource, :as => resource_name, :url => session_path(resource_name), html:{role:"form", class:"form-horizontal" ,id:"form-login"}) do |f| %>
<div style="text-align: center; margin: 20px 0 20px 60px; width: 480px">
<%=image_tag 'logo_ras.gif' %>
</div>
<%= devise_error_messages! %>
<div class="control-group">
<%= f.label :email, {class:"control-label"} %>
<div class="controls">
<%= f.email_field :email, :autofocus => true %>
</div>
</div>
<div class="control-group">
<%= f.label :password, {class:"control-label"} %>
<div class="controls">
<%= f.password_field :password %>
</div>
<%=link_to "¿Olvidaste tu password?", new_user_password_path, {class: "controls"} %>
</div>
<%- if devise_mapping.rememberable? -%>
<div class="check-box">
<label><div class="controls"><%= f.check_box :remember_me %> No cerrar sesion </div></label>
</div>
<% end -%>
<div class="controls"><%= f.submit "Entrar", class:"btn btn-success" %></div>
<div style="text-align: center; margin: 20px 0 0 60px; width: 480px">
<%=link_to image_tag('banner.png'), "http://www.canalcolon.com", :target => "_blank" %>
<div>
Realización: <a href="http://www.gocnetworking.com" target="_blank">Gestió, Organització i Comunicació, S.A.</a><br/>
<%=link_to "Aviso legal", legal_path %>
</div>
</div>
<% end %>
</div>
</div>
</div>
在我的视图中出现了一个布局（标题），我想删除该布局，但我不知道在控制器中我可以做到这一点。这是我的视图中出现的布局：
<!DOCTYPE html>
<html>
<head>
<title>NK-RAS Personalizar es futuro</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= favicon_link_tag "favicon.png" %>
<%= favicon_link_tag "favicon_57_57.png", rel: "apple-touch-icon", sizes: "57x57" %>
<%= favicon_link_tag "favicon_72_72.png", rel: "apple-touch-icon", sizes: "72x72" %>
<%= favicon_link_tag "favicon_114_114.png", rel: "apple-touch-icon", sizes: "114x114" %>
<%= csrf_meta_tags %>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

这是主控制器（应用程序控制器）：
class ApplicationController < ActionController::Base
protect_from_forgery
check_authorization :unless => :devise_controller?
before_filter :audit
helper_method :mobile_request?
def audit
audit = Audit.new
audit.controller = params[:controller]
audit.action = params[:action]
audit.url = self.env["REQUEST_URI"]
audit.ip = self.env["REMOTE_ADDR"]
audit.user_id = current_user.id if current_user
audit.save!

def mobile_request?

可以使用多种布局方式。如果要为给定操作调用特定布局，则应在控制器中执行此操作，而不是在视图中执行。如果你需要在一个视图中调用，给一个局部的布局，那么语法是不同的，你首先调用partial，然后调用布局。
<%= render partial: "comments", layout: "two_column_landing" %>
如果您只想在特定控制器中呈现2列视图，那么在任何方法定义调用之前，在控制器顶部，在类名称下
class ArticlesController < ApplicationController
layout "two_column_landing"
end
如果您只想为控制器中的特定操作调用此布局，可以在方法渲染中执行此操作
def index
@people = Person.all
render layout: "multi-column"
end
您可以参考此问题here了解详情。
如果要从控制器中的所有操作中删除布局，请在类名后添加layout false。
class ArticlesController < ApplicationController
layout false
end
或者如果您还可以为每个操作指定
def login
...
render layout: false
end
