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. 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 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

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 (easy_install nose) and run nosetests or python setup.py test in the root of the distribution. Tests are located in the test/ directory.
