Overview

Warning: In many cases, storing files in the database is a BAD idea. Your database will easily become bloated and the performance can degrade rapidly. See this StackExchange post_ for more information.

.. _StackExchange post: http://programmers.stackexchange.com/questions/150669/is-it-a-bad-practice-to-store-large-files-10-mb-in-a-database

This is a custom storage backend for storing files in the database instead of the file system and is a drop-in replacement for Django's FileSystemStorage. Some benefits of this application:

• no changes needed to existing models, it just works (and if it doesn't, open a ticket!)
• django-admin is implemented and can be used to search, upload, download and manage files
• 100% code coverage with unit tests
