这里我们是安装 pymongo
$easy_install pymongo 1、安装easy_install工具，它的作用类似于Php中的pear，或者Ruby中的gem，或者Perl中的cpan。 2、使用快捷的方法是使用ez_setup.py脚本： #wget -q http://peak.telecommunity.com/dist/ez_setup.py #python ez_setup.py 实例：比如说要安装Python的MySQL支持，可以执行如下命令，系统会自动在pypi网站列表里查找相关软件包： easy_install MySQL-python 这里我们是安装 pymongo easy_install pymongo 如果想删除通过easy_install安装的软件包，比如说：MySQL-python，可以执行命令： easy_install -m MySQL-python
一个例子
#coding=utf-8
from pymongo import Connection
conn = Connection("localhost")
db = conn.foo
test = {"id":1, "novle":"测试一下"}
db.foo.save(test)
cursor = db.foo.find()
for i in cursor:
print i
带有权限认证的例子
#coding=utf-8
from pymongo import Connection,database
conn = Connection("localhost")
db = database.Database(conn,"foo")
r = db.authenticate("test","123")
print r
cursor = db.foo.find()
print cursor
for i in cursor:
print i
输出：
!python simple.py
True
<pymongo.cursor.Cursor object at 0x802858f90>

创建一个 Django项目来测试
guanyu/branches/lidong/mongodb-tests]$ django-admin.py startproject mongodbtest cd mongodbtest $ python manage.py startapp helloworld
编辑3个文件
*urls.py
*helloworld/models.py
*helloworld/views.py
urls.py
(r'^$','mongodbtest.helloworld.views.index'),
helloworld/models.py
#from django.db import models
from mongoengine import *
connect('test')
class PhoneModel(Document):
name = StringField(required=True)
phone = StringField(max_length=50)
helloworld/views.py
from django.http import HttpResponse
from models import PhoneModel
def index(request):
entry = PhoneModel(name='lidong')
entry.phone = '13410320008'
entry.save()
resp = "hello %s , phone :%s" %(entry.name, entry.phone)
return HttpResponse(resp)
检查数据库中的数据
$python
>>> from pymongo import Connection
>>> conn = Connection("localhost")
>>> db = conn.test
