:Info: Minimal database Model management for MongoDB. :Author: Steve Lacy ([email protected])


minimongo is a lightweight, schemaless, Pythonic Object-Oriented interface to MongoDB.

It provides a very thin, dynamicly typed (schema-less) object management layer for any data stored in any MongoDB collection. minimongo directly calls the existing pymongo_ query syntax.

minimongo can easily layer on top of existing MongoDB collections, and will work properly with almost any existing schema, even from third party applications.


If you have setuptools <>_ you can use easy_install -U minimongo. Otherwise, you can download the source from GitHub <>_ and run python install.


  • pymongo_ 1.9+
  • sphinx <>_ (optional -- for documentation generation)


Here's a very brief example of creating an object, querying for it, modifying a field, and then saving it back again:

.. code:: python

from minimongo import Model, Index

class Foo(Model):
    class Meta:
        # Here, we specify the database and collection names.
        # A connection to your DB is automatically created.
        database = "minimongo"
        collection = "rocks"

        # Now, we programatically declare what indices we want.
        # The arguments to the Index constructor are identical to
        # the args to pymongo"s ensure_index function.
        indices = (

if __name__ == "__main__":
    # Create & save an object, and return a local in-memory copy of it:
    foo = Foo({"x": 1, "y": 2}).save()

    # Find that object again, loading it into memory:
    foo = Foo.collection.find_one({"x": 1})

    # Change a field value, and save it back to the DB.
    foo.other = "some data"
