网上找了很多文档，关于django连接mysql，展示mysql数据库中例子比较少，下面是我自己写的例子

S1:创建项目

执行命令:django-admin.py startproject mysite

S2:创建app

执行命令:django-admin.py startapp polls

S3:设置数据库settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        #'NAME': os.path.join(BASE_DIR, 'test'),#database name
        'NAME': 'test',
        'USER':'root',
        'PASSWORD':'123456',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

S4：编写模型文件models.py

from django.db import models
import MySQLdb
import mysite.settings

class student(models.Model):
    name = models.CharField(max_length = 20)
    age = models.CharField(max_length = 20)

    def __str__(self):
        return self.name

S5:编写views.py文件

# *-* coding: utf-8 *-*
import sys
reload(sys)
sys.setdefaultencoding("utf-8")

from django.shortcuts import render, render_to_response
from polls.models import student
from django.http import HttpResponse
import MySQLdb
import mysite.settings
# Create your views here.

def index(request):
    students = student.objects.all()
    name = ""
    for stud in students:
        name = stud.name
        break
    return render_to_response('index.html' , {'students':students , 'name':name})

S6:设置urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'mysite.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^blog/index/$' , 'polls.views.index'),
)

S7:编写index.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>

</head>

<body>
	<p>学生数据如下:</p>
    {{name}}
	<!-- <input type="submit" name="Button" value="展示数据" onclick="ajax_click()"  /> -->
    <table border="10">
    	<tr>
        	<th>姓名</th>
            <th>年龄</th>
        </tr>
        {% for student in students %}
            <tr >
                <td>{{student.name}}</td>
                <td>{{student.age}}</td>
            </tr>
        {% endfor %}
    </table>
</body>
</html>

一个简单的django连接mysql数据库，展示数据库中表的内容的例子就完成了
