如何在Ruby on Rails上将布局链接到视图页面

Question

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？ 我在看一些教程，但看起来太复杂了，我很困惑。

这是我的查看代码：

<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>

我的视图中出现一个布局（标题），我想删除该布局，但是我看不到在控制器中可以执行的操作。 这是在我的视图中显示的布局：

 <!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">

      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!
    end

  DEFAULT_MOBILE_AGENTS = %w(
    palm
    blackberry
    nokia
    phone
    midp
    mobi
    symbian
    chtml
    ericsson
    minimo
    audiovox
    motorola
    samsung
    telit
    upg1
    windows\ ce

    maemo
    fennec
    silk
    playbook
  )

  def mobile_agents
    @mobile_agents ||= Regexp.union(DEFAULT_MOBILE_AGENTS)
  end

  def mobile_request?
    (!(request.user_agent.to_s.downcase =~ mobile_agents).nil?) ||
    (params[:mobile])
  end

end

有很多方法可以使用布局。 如果要为给定操作调用特定的布局，则应在控制器中而不是在视图中进行。 如果需要在视图中调用，以给出局部布局，则语法是不同的，先调用局部，然后再调用布局。

<%= render partial: "comments", layout: "two_column_landing" %>

如果只希望在特定的控制器中呈现2列视图，则在调用任何方法定义之前，在控制器顶部的类名下

class ArticlesController < ApplicationController
  layout "two_column_landing"
end

如果只想为控制器中的特定操作调用此布局，则可以在render方法中进行

def index
  @people = Person.all
  render layout: "multi-column"
end

您可以在此处参考此问题以获取更多详细信息。

如果要从控制器的所有操作中删除布局，请在类名称后添加layout false 。

class ArticlesController < ApplicationController
  layout false
end

或者您也可以为每个动作指定

def login
  ...
  render layout: false
end
