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.
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.
The PyMongo distribution has been tested on Python 2.x, where x >= 3. On Python 2.3 the optional C extension will not be built. This will negatively affect performance, but everything should still work.
Additional dependencies are:
- ElementTree (this is included with Python >= 2.5)
- (to generate documentation) sphinx
- (to auto-discover tests) nose
Here's a basic example (for more see the examples/ directory):
>>> 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('4aba160ee23f6b543e000002')}
>>> 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 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.
