Marrow Mongo is a collection of small, focused utilities written to enhance use of the PyMongo native MongoDB driver <http://api.mongodb.com/python/current/>__ without the overhead, glacial update cycle, complexity, and head-space
requirements of a full active record object document mapper. Additionally, it provides a very light-weight database
connection plugin for the WebCore web framework <https://github.com/marrow/WebCore>__ and Python standard logging
adapter to emit logs to MongoDB.

Additional documentation is provided in the form of an online reference manual <https://mongo.webcore.io/>__.

Installation

Installing marrow.mongo is easy, just execute the following in a terminal::

pip install marrow.mongo

Note: We strongly recommend always using a container, virtualization, or sandboxing environment of some kind when
developing using Python; installing things system-wide is yucky (for a variety of reasons) nine times out of ten. We
prefer light-weight virtualenv <https://virtualenv.pypa.io/en/latest/virtualenv.html>, others prefer solutions as
robust as Vagrant <http://www.vagrantup.com>.

If you add marrow.mongo to the install_requires argument of the call to setup() in your application’s
setup.py file, marrow.mongo will be automatically installed and made available when your own application or
library is installed. We recommend using “less than” version numbers to ensure there are no unintentional
side-effects when updating. Use marrow.mongo<1.2 to get all bugfixes for the current release, and
marrow.mongo<2.0 to get bugfixes and feature updates while ensuring that large breaking changes are not installed.

This package has a few dependencies:

Python 2.7 and above, or Python 3.2 and above, or compatible such as Pypy or Pypy3.
A modern (>3.2) version of the pymongo package.
The Marrow Package and Schema utility packages for plugin handling and declarative syntax support.

Additional instructions on conditional dependencies, package flags, and development version utilization <https://mongo.webcore.io/installation.html>__ are available in the manual.
