django搭建一个通讯录应用
一、环境介绍
window10 64位
Django-1.5.12
python 2.7
Sqlite3
二、基本安装
python2.7安装教程地址：http://jingyan.baidu.com/article/19192ad8399a62e53e5707e0.html
Django安装教程地址：http://www.runoob.com/django/django-install.html
SQLite3安装教程：
下载地址：http://www.sqlite.org/download.html，下载sqlite-dll-win64-x64-3190300和sqlite-tools-win32-x86-3190300
sqlite-dll-win64-x64-3150100.zip包含.def、.dll两个文件
sqlite-tools-win32-x86-3150100.zip包含三个执行文件exe
将它们一起解压到D:\sqlite文件夹，配置环境变量PATH后追加“D:\sqlite;”
二、django创建项目（CMD控制台执行）
创建项目
django-admin.py startproject CloudService
启动服务器(项目目录下)
manage.py runserver
三、创建APP
2)创建app
.\manage.py startapp AddressList
settings.py中添加APP名字
INSTALLED_APPS = (
{...}
‘AddressList‘,
)
5)、数据库配置
在Settings.py配置数据库
DATABASES = {
‘default‘: {
‘ENGINE‘: ‘django.db.backends.sqlite3‘, # Add ‘postgresql_psycopg2‘, ‘mysql‘, ‘sqlite3‘ or ‘oracle‘.
‘NAME‘: r‘D:\it\Python\django_project\CloudService\db\CloudService.db‘, # Or path to database file if using sqlite3.
}
}
连接数据库并创建需要的表，sqlite3用户名x,密码：x，执行命令manage.py syncdb
6)、设置自动admin
基本检查和修改 ,在setting.py中打开
INSTALLED_APPS = (
‘django.contrib.admin‘,
)
在URls.py中：
from django.contrib import admin
urlpatterns = patterns(‘‘,
url(r‘^admin/‘, include(admin.site.urls)),
)
修改语言，在settings.py
MIDDLEWARE_CLASSES = (
‘django.middleware.locale.LocaleMiddleware‘,
)
4、通讯录制作（依托于admin）
登录页面：
D:\it\Python\django_project\CloudService\CloudService\templates\index.html
<div align="center">
<tr><h1>{{ index }}</h1></tr>
<tr><h1>云服务管理系统</h1></tr>
</div>
<div align="center">
<tr>
<td><a href="http://www.mamicode.com/admin" ><button type="button"><h4>登录</h4></button> </a></td>
<td><a href="http://www.mamicode.com/admin" ><button type="button"><h4>注册</h4></button> </a></td>
</tr>
</div>
D:\it\Python\django_project\CloudService\CloudService\view.py
from django.shortcuts import render
def index(request):
context = {}
context[‘index‘] = ‘welcome‘
return render(request, ‘index.html‘, context)
D:\it\Python\django_project\CloudService\CloudService\urls.py
from django.conf.urls import patterns, include, url
from . import view
urlpatterns = patterns(‘‘,
url(r‘^$‘, view.index),
)
D:\it\Python\django_project\CloudService\CloudService\settings.py
TEMPLATE_DIRS = (
‘CloudService/templates‘
)
D:\soft\python27\Lib\site-packages\django\contrib\admin\templates\admin\base_site.html
{% extends "admin/base.html" %}
{% load i18n %}
{% block title %}{{ title }} | {% trans ‘云服务管理系统‘ %}{% endblock %}
{% block branding %}
<h1 id="site-name" align="center">{% trans ‘云服务管理系统登录‘ %}</h1>
{% endblock %}
{% block nav-global %}{% endblock %}
添加 页面：
D:\it\Python\django_project\CloudService\AddressList\models.py
#coding=utf-8
from django.db import models
from django.contrib.auth.models import User
from django.contrib import admin
# Create your models here.
class LinkmanPost(models.Model):
user = models.ForeignKey(User) #用户
name = models.CharField(max_length=15) #姓名
sex = models.BooleanField(default=True) #性别
no = models.CharField(max_length=15) #学号
tel = models.CharField(max_length=15) #手机号
email = models.EmailField() #电子邮件
QQ = models.CharField(max_length=15) #QQ号
brithday = models.CharField(max_length=15) #生日
address = models.CharField(max_length=15) #住址
class LinkmanPostAdmin(admin.ModelAdmin):
list_display = (‘name‘, ‘no‘, ‘tel‘, ‘email‘, ‘QQ‘, ‘brithday‘, ‘address‘)
admin.site.register(LinkmanPost, LinkmanPostAdmin)
D:\it\Python\django_project\CloudService\AddressList\views.py
from django.template import loader, Context
from django.http import HttpResponse
from AddressList.models import LinkmanPost
def LinkShow(request):
posts = LinkmanPost.objects.all()
t = loader.get_template("LinkShow.html")
c = Context({‘posts‘:posts})
return HttpResponse(t.render(c))
D:\it\Python\django_project\CloudService\AddressList\urls.py
from django.conf.urls import *
from views import LinkShow
urlpatterns = patterns(‘‘,
url(r‘^$‘, LinkShow),
)
D:\it\Python\django_project\CloudService\AddressList\templates\LinkShow.html
<table border="1" align="center">
<tr>
<br><br>
<th>用户</th><th>姓名</th><th>性别</th><th>学号</th><th>手机号</th><th>邮箱</th><th>QQ号</th><th>生日</th><th>地址</th>
</th><th>删除</th></th><th>修改</th>
</tr>
{% for post in posts %}
<tr>
<td>{{ post.user }}</td>
<td>{{ post.name }}</td>
<td>{{ post.sex }}</td>
<td>{{ post.no }}</td>
<td>{{ post.tel }}</td>
<td>{{ post.email }}</td>
<td>{{ post.QQ }}</td>
<td>{{ post.brithday }}</td>
<td>{{ post.address }}</td>
<td><a href="http://www.mamicode.com/deleted?id={{ post.id }}">删除</a></td>
<td><a href="http://www.mamicode.com/admin/AddressList/linkmanpost/{{ post.id }}">修改</a></td>
</tr>
{% endfor %}
</table>
D:\it\Python\django_project\CloudService\CloudService\urls.py
from django.conf.urls import patterns, include, url
from . import view
urlpatterns = patterns(‘‘,
url(r‘^admin/‘, include(admin.site.urls)),
url(r‘^linkshow/‘, include(‘AddressList.urls‘)),
)
D:\soft\python27\Lib\site-packages\django\contrib\admin\templates\admin\index.html
{% block content %}
<div id="content-main">
{% if app_list %}
{% for app in app_list %}
<div class="module">
<table>
{% for model in app.models %}
<tr>
{% if model.admin_url %}
<th scope="row"><a href="http://www.mamicode.com/linkshow">{# <a href="http://www.mamicode.com/{{ model.admin_url }}"> #}
{% ifequal model.name ‘Linkman posts‘ %}
{% trans ‘通讯录‘ %}
{% else%}
{% trans ‘Add‘ %}
{% endifequal %}
</a></th>
同步数据库manage.py sycdb
删除功能：
D:\it\Python\django_project\CloudService\AddressList\views.py
def delete_link(request):
id = request.GET[‘id‘]
bb = LinkmanPost.objects.get(id = id)
bb.delete()
t = loader.get_template("LinkShow.html")
return HttpResponse(t.render)
D:\it\Python\django_project\CloudService\AddressList\urls.py
from views import LinkShow, delete_link
urlpatterns = patterns(‘‘,
url(r‘^deleted$‘, delete_link),
)
