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="./admin" ><button type="button"><h4>登录</h4></button> </a></td>
        <td><a href="./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="./deleted?id={{ post.id }}">删除</a></td>
    <td><a href="../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="../linkshow">{#  <a href="{{ 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),
                       )
