django请求响应原理图:

set配置

命令 hj@deepin:~/Desktop/huangjin/huangjin$ vim settings.py

代码

INSTALLED_APPS = [

'django.contrib.admin',s

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.messages',

'django.contrib.staticfiles',

'blog',

]

LANGUAGE_CODE = 'zh-Hans'

TIME_ZONE = 'Asia/Shanghai'

建立项目应用模板

hj@deepin:~/Desktop$ django-admin startproject huangjin 建立名为huangjin项目

hj@deepin:~/Desktop$ python manage.py startapp blog 建立名为blog应用

hj@deepin:~/Desktop/huangjin/blog$ mkdir templates #模板

hj@deepin:~/Desktop/huangjin/blog/templates$ mkdir blog #避免多应用的同名HTML冲突创建一个以APP为名称的文件夹，将HTML文件放入到此文件夹下

hj@deepin:~/Desktop/huangjin/blog/templates/blog$ touch index.html

hj@deepin:~/Desktop/huangjin/blog/templates/blog$ touch article_page.html

hj@deepin:~/Desktop/huangjin/blog/templates/blog$ touch edit_page.html

Ps :indexhtml 文章主界面 article_page.html 文章内容页面 edit_page.html 编辑业面

URL 配置

在根目录urls.py中引入include ，在APP目录下创建/复制urls.py的同名文件，格式与个人那个目录下的urls.py相同

命令

hj@deepin:~/Desktop/huangjin/huangjin$ vim urls.py

代码

from django.conf.urls import url,include

from django.contrib import admin

from blog.views import index

urlpatterns = [

url(r'^admin/', admin.site.urls),

url(r'^blog/',include('blog.urls',namespace='blog')),

]

命令

hj@deepin:~/Desktop/huangjin$ cp huangjin/urls.py blog/urls.py #复制

hj@deepin:~/Desktop/huangjin/blog$ vim urls.py

代码

from django.conf.urls import url,include

from django.contrib import admin

from blog.views import index

from . import views

urlpatterns = [

url(r'^index/$', index),

url(r'^article/(?P<article_id>[0-9]+)$',views.article_page,name='article_page'),

url(r'^edit/(?P<article_id>[0-9]+)$',views.edit_page, name='edit_page'),

url(r'^edit/action$',views.edit_action, name='edit_action'),

]

博客页面构造

主界面 Index.html 显示新建、标题、内容三项

Django中model对应一张数据表，数据表以类的形式表现。在models.py中引入models模块创建类，继承models.Model. 在该类中创建数据表的字段

命令

hj@deepin:~/Desktop/huangjin/blog$ vim models.py

代码

# -*- coding: utf-8 -*-

from __future__ import unicode_literals

from django.db import models

from django.utils.encoding import python_2_unicode_compatible

# Create your models here.

class Article(models.Model):

title = models.CharField(max_length=32,default = 'Title')

content = models.TextField(null=True)

视图函数views

命令

hj@deepin:~/Desktop/huangjin/blog$ vim views.py

代码

from django.shortcuts import render

from . import models

from django.http import HttpResponse

# -*- coding: utf-8 -*-

from __future__ import unicode_literals

from django.shortcuts import render

from django.http import HttpResponse

from . import models

# Create your views here.

def index(request):

articles=models.Article.objects.all()

return render(request, "blog/index.html",{'articles':articles})

def article_page(request,article_id):

article = models.Article.objects.get(pk=article_id)

return render(request,'blog/article_page.html',{'article':article})

def edit_page(request,article_id):

if str(article_id)== '0':

return render(request,'blog/edit_page.html')

article = models.Article.objects.get(pk=article_id)

return render(request,'blog/edit_page.html',{'article':article})

def edit_action(request):

title = request.POST.get('title','TITLE')

content = request.POST.get('content','CONTENT')

article_id = request.POST.get('article_id','0')

if article_id =='0':

models.Article.objects.create(title=title,content=content)

articles=models.Article.objects.all()

return render(request, "blog/index.html",{'articles':articles})

article = models.Article.objects.get(pk=article_id)

article.title=title

article.content=content

article.save()

return render(request,'blog/article_page.html',{'article':article})

前台HTML

Index部分

命令

hj@deepin:~/Desktop/huangjin/blog/templates/blog$ vim index.html

代码

<html>

<head>

<title>Title</title>

</head>

<body>

<br/>

{% for article in articles %}

<a href="{% url 'blog:article_page' article.id %}">{{article.title}}</a>

<br/>

{% endfor %}

</body>

</html>

article_page部分

<html>

<head>

<title>Article Page</title>

</head>

<body>

<h1>{{article.title}}</h1>

<br/>

<h3>{{article.content}}</h3>

<br/>

</body>

</html>

edit_page 部分

<html>

<head>

</head>

<body>

{% csrf_token %}

<label>文章标题

</label>

<br/>

<label>文章内容

</label>

<br/>

</form>

</body>

</html>
