django1.6 博客的快速搭建second blog v2
一：效果总览
这是在前一篇博文的基础上改进的博客，还没有美化页面，暂且学习中就这样吧，以后版本改进中
首先看下具体效果:
127.0.0.1/articles/2014
127.0.0.1/news/articles/2014
上面是两种形式的url mapping，都可以访问，结果一样
只查看2014年的博客;
博客的列表
博客文章的详细页面：
二：博客目录结构
三:几个重要的文件

在模版中使用静态文件
{% block content %}{% endblock %}
疑问;这里的STATIC_URL的绝对路径设置的很有疑惑，暂且先这样弄吧

[root@localhost mysite16_5_demo]# 这里的URL能匹配到
127.0.0.1/articles/2014
这就为什么可以同时匹配到
127.0.0.1/articles/2014
127.0.0.1/news/articles/2014
总结：
在这个过程中遇到过一些问题，皆因自己的不细心导致，没什么需要特别注意的
在python shell中后台操作的过程中，需要先执行，具体解决过程如下：
