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.

Support / Feedback

For issues with, questions about, or feedback for PyMongo, please look into our support channels <http://www.mongodb.org/about/support>. Please do not email any of the PyMongo developers directly with issues or questions - you're more likely to get an answer on the mongodb-user <http://groups.google.com/group/mongodb-user> list on Google Groups.

Bugs / Feature Requests

Think youve found a bug? Want to see a new feature in PyMongo? Please open a case in our issue management tool, JIRA:

• Create an account and login <https://jira.mongodb.org>_.
• Navigate to the PYTHON project <https://jira.mongodb.org/browse/PYTHON>_.
• Click Create Issue - Please provide as much information as possible about the issue type and how to reproduce it.

Bug reports in JIRA for all driver projects (i.e. PYTHON, CSHARP, JAVA) and the Core Server (i.e. SERVER) project are public.

How To Ask For Help

Please include all of the following information when opening an issue:

• Detailed steps to reproduce the problem, including full traceback, if possible.

• The exact python version used, with patch level::

  $ python -c "import sys; print(sys.version)"

• The exact version of PyMongo used, with patch level::

  $ python -c "import pymongo; print(pymongo.version); print(pymongo.has_c())"

• The operating system and version (e.g. Windows 7, OSX 10.8, ...)

• Web framework or asynchronous network library used, if any, with version (e.g. Django 1.7, mod_wsgi 4.3.0, gevent 1.0.1, Tornado 4.0.2, ...)

Security Vulnerabilities

If youve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here <http://docs.mongodb.org/manual/tutorial/create-a-vulnerability-report>_.

Installation

If you have setuptools <http://pythonhosted.org/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.

Do not install the "bson" package. PyMongo comes with its own bson package; doing "easy_install bson" installs a third-party package that is incompatible with PyMongo.

Dependencies

The PyMongo distribution is supported and tested on Python 2.x (where x >= 6) and Python 3.x (where x >= 2). PyMongo versions before 3.0 also support Python 2.4, 2.5, and 3.1.

Optional packages:

• backports.pbkdf2 <https://pypi.python.org/pypi/backports.pbkdf2/>_, improves authentication performance with SCRAM-SHA-1, the default authentication mechanism for MongoDB 3.0+. It especially improves performance on Python older than 2.7.8, or on Python 3 before Python 3.4.
• pykerberos <https://pypi.python.org/pypi/pykerberos>_ is required for the GSSAPI authentication mechanism.
• Monotime <https://pypi.python.org/pypi/Monotime>_ adds support for a monotonic clock, which improves reliability in environments where clock adjustments are frequent. Not needed in Python 3.3+.
• wincertstore <https://pypi.python.org/pypi/wincertstore>_ adds support for verifying server SSL certificates using Windows provided CA certificates on older versions of python. Not needed or used with versions of Python 2 beginning with 2.7.9, or versions of Python 3 beginning with 3.4.0.
• certifi <https://pypi.python.org/pypi/certifi>_ adds support for using the Mozilla CA bundle with SSL to verify server certificates. Not needed or used with versions of Python 2 beginning with 2.7.9 on any OS, versions of Python 3 beginning with Python 3.4.0 on Windows, or versions of Python 3 beginning with Python 3.2.0 on operating systems other than Windows.

Additional dependencies are:

• (to generate documentation) sphinx_
• (to run the tests under Python 2.6) unittest2_

Examples

Here's a basic example (for more see the examples section of the docs):

.. code-block:: pycon

import pymongo client = pymongo.MongoClient("localhost", 27017) db = client.test db.name u'test' db.mycollection Collection(Database(MongoClient('localhost', 27017), u'test'), u'mycollection') db.mycollection.insertone({"x": 10}).insertedid ObjectId('4aba15ebe23f6b53b0000000') db.mycollection.insertone({"x": 8}).insertedid ObjectId('4aba160ee23f6b543e000000') db.mycollection.insertone({"x": 11}).insertedid ObjectId('4aba160ee23f6b543e000002') db.mycollection.findone() {u'x': 10, u'id': ObjectId('4aba15ebe23f6b53b0000000')} for item in db.mycollection.find(): ... print item["x"] ... 10 8 11 db.mycollection.createindex("x") u'x1' for item in db.mycollection.find().sort("x", pymongo.ASCENDING): ... print item["x"] ... 8 10 11 [item["x"] for item in db.mycollection.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 run python setup.py test in the root of the distribution. Note that you will need unittest2_ to run the tests under Python 2.6.

To verify that PyMongo works with Gevent's monkey-patching::

$ python green_framework_test.py gevent

Or with Eventlet's::

$ python green_framework_test.py eventlet
