2.1.博客首页设计

(1)settings.py

MEDIA_ROOT = os.path.join(BASE_DIR,'media').replace("//","/")
MEDIA_URL = '/media/'

(2)website/urls

添加图片的url

from django.conf.urls import url,include
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^blog/',include('blog.urls') ), ] + static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT ) #添加图片的url

(3)blog/models.py

添加两个方法

class Entry(models.Model):
.
.
.
def get_absolute_url(self):
#获取当前博客详情页的url
return reverse("blog:blog_detail",kwargs={"blog_id":self.id}) #app名字,详情页url的别名,参数是当前博客的id def increase_visiting(self):
#访问量加1
self.visiting += 1
self.save(update_fields=['visiting']) #只保存某个字段

(4)views.py

from django.shortcuts import render
from . import models def index(request):
entries = models.Entry.objects.all() return render(request,'blog/index.html',locals()) def detail(request,blog_id):
entry = models.Entry.objects.get(id=blog_id)
entry.increase_visiting() return render(request,'blog/detail.html',locals())

(5)index.py

{% extends 'blog/base.html' %}

{% block title %}博客首页{% endblock %}

{% block content %}

    <div class="container">
<div class="row">
<div class="col-md-9">
{% for entry in entries %}
<h2><a href="{{ entry.get_absolute_url }}">{{ entry.title }}</a></h2> <br>
{% if entry.img %}
<img src="{{ entry.img.url }}" width="60%" height="270px"/>
{% endif %}
{% if entry.abstract %}
<p>{{ entry.abstract }}</p>
{% else %}
<p>{{ entry.body|truncatechars:180 }}</p>
{% endif %}
<p>
<span>作者:{{ entry.author }}</span>
<span>&nbsp;&nbsp;&nbsp;&nbsp;发布时间:{{ entry.created_time }}</span>
<span>&nbsp;&nbsp;&nbsp;&nbsp;阅读数:{{ entry.visiting }}</span>
</p>
{% endfor %} </div> </div> </div> {% endblock %}

(6)detail.html

{% extends 'blog/base.html' %}

{% block title %}博客详情页{% endblock %}

{% block content %}
博客{{ blog_id }}的详情页
{% endblock %}

2.2.博客详情页面

detail.html

{% extends 'blog/base.html' %}

{% block title %}博客详情页{% endblock %}

{% block content %}
<div class="container">
<div class="row">
<div class="col-md-9">
<h1>{{ entry.title }}</h1>
<p>
<strong>{{ entry.author }}</strong>
&nbsp;&nbsp;&nbsp;&nbsp;{{ entry.created_time|date:'Y年m月d日' }}
&nbsp;&nbsp;&nbsp;&nbsp;分类:
{% for category in entry.category.all %}
&nbsp;&nbsp;<a href="#">{{ category.name }}</a>
{% endfor %} &nbsp;&nbsp;&nbsp;&nbsp;标签:
{% for tag in entry.tags.all %}
&nbsp;&nbsp;<a href="#">{{ tag.name }}</a>
{% endfor %} &nbsp;&nbsp;&nbsp;&nbsp;浏览量:
&nbsp;&nbsp;{{ entry.visiting }} {% if entry.img %}
<img src="{{ entry.img.url }}" width="60%" height="270px"/>
{% endif %}
<hr />
<p>
{{ entry.body }}
</p>
</p>
</div>
</div>
</div> {% endblock %}

2.3.Markdown排版、语法高亮和生成目录

(1)安装模块

pip install markdown

pip install pygments

(2)views.py

import markdown,pygments

def detail(request,blog_id):
entry = models.Entry.objects.get(id=blog_id)
md = markdown.Markdown(extensions=[
'markdown.extensions.extra',
'markdown.extensions.codehilite',
'markdown.extensions.toc',
])
entry.body = md.convert(entry.body)
entry.toc = md.toc
entry.increase_visiting() return render(request,'blog/detail.html',locals())

(3)detail.html

把github.css放到blog/css里面,detail.html引用样式

{% extends 'blog/base.html' %}
{% load staticfiles %} {% block title %}博客详情页{% endblock %}
{% block css %}
<link rel="stylesheet" href="{% static 'blog/css/github.css' %}">
{% endblock %}

标签和正文都加salf

(4)后台添加博客

Markdown语法测试篇

## 1.python语言介绍
编程语言主要从以下几个角度进行分类:编译型,静态型,动态性,强类型定义语言和弱类型定义语言 - 编译型:有一个负责翻译的程序来对我们的源代码进行转换,生成对应的可执行代码,这个过程就是编译(Compile),而负责编译的程序就被称为编译器(Compiler) - 通常我们所说的动态语言,静态语言是指动态类型语言和静态类型语言 ## 2.python的优缺点 - 优点:简单、开发效率高、高级语言、可移植性、可扩展性、可嵌入性 - 缺点:速度慢,但是相对的、代码不能加密、线程不能利用多CPU问题 ## 3.高阶函数
```python
def func():
print('in the func')
return foo()
def foo():
print('in the foo()')
return 666 res = func()
print(res)
```
