About
=====
The PyMongo distribution contains tools for interacting with MongoDB
database from Python. The ``bson`` package is an implementation of
the `BSON format <http://bsonspec.org>`_ for Python. The ``pymongo``
package is a native Python driver for MongoDB. The ``gridfs`` package
is a `gridfs
<http://www.mongodb.org/display/DOCS/GridFS+Specification>`_
implementation on top of ``pymongo``.
Issues / Questions / Feedback
=============================
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
<http://jira.mongodb.org>`_. 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.
Installation
============
If you have `setuptools
<http://peak.telecommunity.com/DevCenter/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.
Dependencies
============
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:
- (to generate documentation) sphinx_
- (to auto-discover tests) `nose <http://somethingaboutorange.com/mrl/projects/nose/>`_
Examples
========
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]
Documentation
=============
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.
Testing
=======
The easiest way to run the tests is to install `nose
<http://somethingaboutorange.com/mrl/projects/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.
