The PyMongo distribution contains tools for interacting with MongoDB
database from Python. The bson package is an implementation of
the BSON format for Python. The pymongo
package is a native Python driver for MongoDB. The gridfs package
is a gridfs
implementation on top of pymongo.
Any issues with, questions about, or feedback for PyMongo should be sent to the mongodb-user list on Google Groups. For confirmed issues or feature requests, open a case on jira. Please do not e-mail any of the PyMongo developers directly with issues or questions - you're more likely to get an answer on the list.
If you have setuptools installed you should be able to do easy_install pymongo to install PyMongo. Otherwise you can download the project source and do python setup.py install to install.
The PyMongo distribution is supported and tested on Python 2.x, where x >= 4. PyMongo versions <= 1.3 also supported Python 2.3, but that is no longer supported. If you need to use Python 2.3 please contact us.
Additional dependencies are:
Here's a basic example (for more see the examples section of the docs):
>>> import pymongo
>>> connection = pymongo.Connection("localhost", 27017)
>>> db = connection.test
>>> db.name()
u'test'
>>> db.my_collection
Collection(Database(Connection('localhost', 27017), u'test'), u'my_collection')
>>> db.my_collection.save({"x": 10})
ObjectId('4aba15ebe23f6b53b0000000')
>>> db.my_collection.save({"x": 8})
ObjectId('4aba160ee23f6b543e000000')
>>> db.my_collection.save({"x": 11})
ObjectId('4aba160ee23f6b543e000002')
>>> db.my_collection.find_one()
{u'x': 10, u'_id': ObjectId('4aba15ebe23f6b53b0000000')}
>>> for item in db.my_collection.find():
... print item["x"]
...
10
8
11
>>> db.my_collection.create_index("x")
u'x_1'
>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
... print item["x"]
...
8
10
11
>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
[8, 11]You will need sphinx installed to generate the documentation. Documentation can be generated by running python setup.py doc. Generated documentation can be found in the doc/build/html/ directory.
The easiest way to run the tests is to install nose (easy_install nose) and run nosetests or python setup.py test in the root of the distribution. Tests are located in the test/ directory.
