(转)Django ====> 实战学习篇八 增加目录页,设置统一布局

        对于这个项目,我们增加一个目录页,用来显示物品,并且提供加入购物车的按钮,对于模板,我们进行统一设置,根据继承模板的操作对子模板进行重写,弄好整体的风格设定,并完成设计。类似如下风格:

  

 

        前面的scaffold内容说明了模板的内容,我们把统一的内容写到base.html中,先不做这个,先来实现目录页。我的顺序是:

  1. 修改URLconf 叫做/depotapp/store,在url中加入下边这行:
    /depotapp/urls.py
    
    (r'^store', store_view),
  2. 修改视图函数view,store是其对应的视图函数,在depotapp的views里加入下边的内容:
    /depotapp/views.py
    
    import datetime
    def store_view(request):
        products =         Product.objects.filter(date_available__gt=datetime.datetime.now().date()) .o    rder_by("-date_available")
         #products = Product.objects.all() 上边的不行用这行先代替
         t = get_template('depotapp/store.html')
         c = RequestContext(request,locals())
         return HttpResponse(t.render(c))
  3. 使用/depot/templates/depotapp/store.html作为模板,代码如下:
    {% extends "base.html" %}  
      
    {% block title %} 产品目录 {% endblock %}  
    {% block pagename %} 产品目录 {% endblock %}  
      
    {% block content %}   
    {% for item in products %}  
    <div class="row" style="padding-top:10">  
        <div class="span3 media-grid">  
            <a href="#">  
            <img class="thumbnail" src="{{item.image_url}}" alt="">  
            </a>  
        </div>  
        <div class="span-two-thirds">  
            <h3>{{item.title}}</h3>  
            <br/>  
            {{item.description}}  
            <br/>  
            <br/>  
            <br/>  
            <div class="row">  
                <div class="span2"><h3>¥{{item.price|floatformat:"2"}}</h3></div>  
                <div class="span"><a class="btn primary" href="#">加入购物车</a></div>  
            </div>  
        </div>  
      
    </div>  
    <div class="page-header">  
    </div>  
    {% endfor %}  
    {% endblock %}  
  4. 上边的模板继承了base.html,修改base.html ,并加入共用的内容部分,为整个站点设计了风格布局,代码如下:
    <html xmlns="http://www.w3.org/1999/xhtml">  
    <head>  
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8">  
        <meta name="description" content="a depot implement with Django"/>  
        <meta name="keywords" content="django,depot" />  
        <meta name="author" content="Holbrook(http://hi.csdn.net/space-2668.html)" />  
        <title>{% block title %} 标题 {% endblock %}</title>  
        <!-- Le HTML5 shim, for IE6-8 support of HTML elements -->  
        <!--[if lt IE 9]>  
          <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>  
        <![endif]-->  
      
        <!-- Le styles -->  
        <link rel="stylesheet" href="/static/css/bootstrap.min.css">  
        <link rel="stylesheet" href="/static/css/layout.css">  
    </head>  
    <body>  
        <div class="topbar">  
          <div class="fill">  
            <div class="container">  
              <a class="brand" href="#">Depot</a>  
              <ul class="nav">  
                <li class="active"><a href="#">首页</a></li>  
                <li><a href="#about">问题</a></li>  
                <li><a href="#contact">新闻</a></li>  
                <li><a href="#contact">联系我们</a></li>  
              </ul>  
              <form action="" class="pull-right">  
                <input class="input-small" type="text" placeholder="用户名">  
                <input class="input-small" type="password" placeholder="密码">  
                <button class="btn" type="submit">登录</button>  
              </form>  
            </div>  
          </div>  
        </div>  
      
        <div class="container">  
      
          <div class="content">  
            <div class="page-header">  
              <h1>{% block pagename %} 页面名称 {% endblock %}</h1>  
            </div>  
            {% block content %}   
            内容  
            {% endblock %}  
        </div><!-- /content -->  
      
          
    </div><!-- /container -->  
    </body>  
    </html>  

    用了很少的代码增加了目录页,并且设计了网页的整体布局。
