About

The PyMongo distribution contains tools for interacting with the Mongo database from Python. The pymongo package is a native Python driver for the Mongo database. The gridfs package is a gridfs implementation on top of pymongo.

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 has been tested on both Python 2.5 and Python 2.6. Additional dependencies are:

• ElementTree
• (to generate documentation) epydoc
• (to auto-discover tests) nose

Examples

Here's a basic example (for more see the examples/ directory):

>>> from pymongo.connection import Connection
>>> connection = 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('D\x87\xdd\xe8\xd6\x0f\x89\xfc\xab\x06\xac\x8e')
>>> db.my_collection.save({"x": 8})
ObjectId('\xde\x0b\xec^\xdc\x11`\x12\xf8\xeb/\xcf')
>>> db.my_collection.save({"x": 11})
ObjectId('\t6\xc6\x07\xb3\xfc\x87\xc4\x82\x04\x0f\\')
>>> db.my_collection.find_one()
{u'x': 10, u'_id': ObjectId('D\x87\xdd\xe8\xd6\x0f\x89\xfc\xab\x06\xac\x8e')}
>>> for item in db.my_collection.find():
...     print item["x"]
...
10
8
11
>>> from pymongo import ASCENDING
>>> db.my_collection.create_index("x", ASCENDING)
u'x_1'
>>> for item in db.my_collection.find().sort("x", 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 epydoc installed to generate the documentation. Documentation can be generated by running epydoc --config=epydoc-config. Generated documentation can be found in the doc/ 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.
