django之定义模板语法06（过滤器之多重过滤）

<html>
    <head>
        <title>DOcument</title>
    </head>
    <body>
        <h1>{{user}}</h1>
        </br>
        </br>
        <h1>过滤器</h1>  
        <p>1、运用到了Linux管道思想</p>  
        <p>2、先将book的值变为大写，再转化为小写，再转化为首字母大写</p>  
        
        {% for book in user %}
            <li>{{book | upper |lower | capfirst}}</li>   
        {% empty %}
            <li>没有找到书籍</li>    
        {% endfor %}
    </body>
</html>
