How to operate CouchDB in python and couchdb in python

This article briefly describes how to operate CouchDB in python and shares it with you for your reference. The specific method is as follows:

1. Install the python couchDb Library:

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

2. Connect to the server

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

3. Create a database

>>> Db = couch. create ('test') # create a database> db = couch ['mydb'] # use an existing database

4. Create a document and insert it to the database:

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

The save () method returns the '_ id',' _ rev' fields.

5. query the database by id

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

6. Update the document:

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

7. traverse the database

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

8. delete documents and clear Databases

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