仅在首页上添加META关键字和说明

Question

我只想输入我的ruby网站的关键字和主页说明。主页上有2个文件：

1- main_controller
2- home_page.html.erb


<% content_for :html_title, 'Erratum HUmanum Est' %>
<div class="clear"></div>
<div id="video">
  <div class="container">
        <div class="video-glow">
          <h1><%= t('application.home_page.heading')%></h1>
            <div class="clear"></div>
            <div class="video-section">
                <iframe width="418" height="235" src="https://www.youtube.com/embed/sfsfsfsfsfsfQ?rel=0;hd=1" frameborder="0" allowfullscreen></iframe>
            </div>
        </div>
    </div>
</div>

如何在这些页面上输入元描述和关键字？（我不想为此输入任何新的红宝石宝石）谢谢，罗马

Answer 1

在您的内容中application.html.erb添加如下内容：

<meta name="description" content="<%= yield(:description) %>" />
<meta name="keywords" content="<%= yield(:keywords) %>" />

然后home_page.html.erb添加这样的东西；

<%= provide(:description, 'I would like to enter keywords and a description of the home page only of my ruby website. The home page has ') %>  
<%= provide(:keywords, 'Home, fred, grace, heaven, george') %>  

当您不传递任何内容时，它将保持空白且没有meta_tags。
