Django+Bootstrap+Mysql 搭建个人博客(二)

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)
```
