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.
For issues with, questions about, or feedback for PyMongo, please look into our support channels. 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 list on Google Groups.
Think you’ve 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.
- Navigate to the PYTHON project.
- 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.
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, ...)
If you’ve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here.
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.
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.
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, 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 is required for the GSSAPI authentication mechanism.
- Monotime adds support for a monotonic clock, which improves reliability in environments where clock adjustments are frequent. Not needed in Python 3.3+.
Additional dependencies are:
Here's a basic example (for more see the examples section of the docs):
>>> import pymongo
>>> client = pymongo.MongoClient("localhost", 27017)
>>> db = client.test
>>> db.name
u'test'
>>> db.my_collection
Collection(Database(MongoClient('localhost', 27017), u'test'), u'my_collection')
>>> db.my_collection.insert_one({"x": 10}).inserted_id
ObjectId('4aba15ebe23f6b53b0000000')
>>> db.my_collection.insert_one({"x": 8}).inserted_id
ObjectId('4aba160ee23f6b543e000000')
>>> db.my_collection.insert_one({"x": 11}).inserted_id
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 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
