Part.Three中实现了注册和登录的功能，那这一节完成主页内容的填充，并且主页中要实现简单的可以查找代码的功能。
而且有于公共代码部分存储在本机，所以用存储路径的方式存储本地代码的信息。
先写了index.html↓
{% extends "main.html" %}
{% block content %}
<nav class="navbar navbar-default navbar-static-top" role="navigation">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="sr-only">Toggle navigation</span><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></button> <a class="navbar-brand" href="#">TSSS</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li>
<a href="/">首页</a>
</li>
<li>
<a href="/code/list">算法</a>
</li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">代码<strong class="caret"></strong></a>
<ul class="dropdown-menu">

</li>
</ul>
</li>
</ul>
<form class="navbar-form navbar-left" role="search" action="/" method="POST">
<div class="form-group">
<input type="text" class="form-control" name="codename" />
</div> <button type="submit" class="btn btn-default">查找</button>
</form>
{%if not cookieName%}
<ul class="nav navbar-nav navbar-right">
<li>
<a href="/sign/in">登入</a>
</li>
<li>
<a href="/sign/up">注册</a>
</li>
</ul>
{% else %}
<ul class="nav navbar-nav navbar-right">
<li>
<a href="/user/main">{{ username }}</a>
</li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">更多<strong class="caret"></strong></a>
<ul class="dropdown-menu">

<a href="/user/plan">我的计划</a>
</li>
<li class="divider">

<li>
<a href="/sign/out">退出登录</a>
</li>
</ul>
</li>
</ul>
{% end %}
</div>
</nav>
<span class="label label-danger">本日最佳</span>
<div class="jumbotron well">
<h1>
Hello, world!
</h1>
<p>
#include <stdio.h>
</p>
<p>
int main()
</p>
<p>
{
</p>
<p>
printf("Hello,World!");
</p>
<p>
return 0;
</p>
<p>
}
</p>
<p>
<a class="btn btn-primary btn-large" href="#">查看讨论</a>
</p>
</div>
<div class="list-group">
<a href="#" class="list-group-item active">最新文章</a> {% for blog in blogs %}
<div class="list-group-item">
<a href="/blog/{{ blog['_id'] }}">{{ blog['title'] }}</a>
</div>
{% end %}
</div>
{% end %}
↑其中Hello world那部分可以以后根据评论数排序出来的第一个换掉。
再来看一下数据库规范↓
codedb:blogs _id ID author 作者 title 题目 content 内容 datetime 时间
然后写IndexHandler↓
class IndexHandler(web.RequestHandler):
def get(self):
coll = self.application.db.blogs
username = self.get_cookie('username')
blogs = coll.find().sort('datetime',pymongo.DESCENDING)
self.('index.html',username=username,blogs=blogs)
def post(self):
coll = self.application.db.codes
codename = self.get_argument('codename')
codeone = coll.find_one({'title':codename})
if codeone:
try:
with open(os.path.dirname(__file__),findcode['path'],'r') as f:
content = f.read()
self.render('code\codeview.html',codeone = codeone)
except:
self.set_status(404)
self.write({'error':'code not be here now'})
这样主页的内容就填充完成了。
