Python Operation Couchdb

To install the Python couchdb library:

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

Connecting to a server

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

Create a database

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

Create the document and insert it into the database:

>>> doc = {‘foo‘: ‘bar‘}>>> db.save(doc)(‘e0658cab843b59e63c8779a9a5000b01‘, ‘1-4c6114c65e295552ab1019e2b046b10e‘)>>> doc{‘_rev‘: ‘1-4c6114c65e295552ab1019e2b046b10e‘, ‘foo‘: ‘bar‘, ‘_id‘: ‘e0658cab843b59e63c8779a9a5000b01‘}save()方法会返回‘_id‘,‘_rev‘字段

Querying the database by ID

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

To update a document:

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

Traversing the database

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

Delete a document and clean the database

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