Dynamic-preferences is a Django app, BSD-licensed, designed to help you manage your project settings. While most of the time, a settings.py file is sufficient, there are some situations where you need something more flexible such as:

* per-user settings (or, generally speaking, per instance settings) * settings change without server restart

For per-instance settings, you could actually store them in some kind of profile model. However, it means that every time you want to add a new setting, you need to add a new column to the profile DB table. Not very efficient.

Dynamic-preferences allow you to register settings (a.k.a. preferences) in a declarative way. Preferences values are serialized before storage in database, and automatically deserialized when you need them.

With dynamic-preferences, you can update settings on the fly, through django's admin or custom forms, without restarting your application.
