python操作CouchDB的方法-Python Tutorial-php.cn

本文简单讲述了python操作CouchDB的方法，分享给大家供大家参考。具体方法如下：

1.安装python couchDb库：

https://pypi.python.org/pypi/CouchDB/0.10

2.连接服务器

>>> import couchdb
>>> couch = couchdb.Server('http://example.com:5984/')

Copy after login

3.创建数据库

>>> db = couch.create('test') # 新建数据库
>>> db = couch['mydb'] # 使用已经存在的数据库

Copy after login

4.创建文档并插入到数据库：

>>> doc = {'foo': 'bar'}
>>> db.save(doc)
('e0658cab843b59e63c8779a9a5000b01', '1-4c6114c65e295552ab1019e2b046b10e')
>>> doc
{'_rev': '1-4c6114c65e295552ab1019e2b046b10e', 'foo': 'bar', '_id': 'e0658cab843b59e63c8779a9a5000b01'}

Copy after login

save()方法会返回'_id','_rev'字段

5.通过id查询数据库

>>> db['e0658cab843b59e63c8779a9a5000b01']
<Document 'e0658cab843b59e63c8779a9a5000b01'@'1-4c6114c65e295552ab1019e2b046b10e' {'foo': 'bar'}>

Copy after login

6.更新文档：

>>> data = db["5fecc0d7fe5acac6b46359b5eec4f3ff"]  
>>> data['billSeconds'] = 191
>>> db.save(data)
(u'5fecc0d7fe5acac6b46359b5eec4f3ff', u'3-6b8a6bb9f2428c510dcacdd5c918d632')

Copy after login

7.遍历数据库

>>> for id in db:
...   print id
...
'e0658cab843b59e63c8779a9a5000b01'

Copy after login

8.删除文档并清理数据库

>>> db.delete(doc)
>>> couch.delete('test')

Copy after login

希望本文所述对大家的Python程序设计有所帮助。
