Example 3 from django-mongonaut

django-mongonaut (project documentation and PyPI package information) provides an introspective interface for working with MongoDB via mongoengine. The project has its own new code to map MongoDB to the Django Admin interface.

django-mongonaut's highlighted features include automatic introspection of mongoengine documents, the ability to constrain who sees what and what they can do and full control for adding, editing and deleting documents.

The django-mongonaut project is open sourced under the MIT License and it is maintained by the developer community group Jazzband.
