Django 3 Preferences
A Django app and fork of django_preferences allowing the creation of site preferences in the Django admin panel
What does it do?
Provides a singleton view in the Admin panel for Preferences objects and an interface to allow the preferences to be used in code or in templates.
How is it different from django_preferences?
This is a fork and revision of the django_preferences package, which has not been updated in a number of years. The main changes are:

Since most users only manage one site, the dependency on django.contrib.sites has been removed, which makes for a nicer user experience.
The ability to save and add more records has been disabled in this version, so that only one preferences object can ever exist.
This package is built to work with Django 3.1 and above.

Requirements

Python 3
Django 3.1 and above

Installation

Run pip3 install django3-preferences
Add preferences to your INSTALLED_APPS
If you want your preferences exposed in your templates, then add the preferences.context_processors.preferences_context_processor to your TEMPLATES > OPTIONS > context-processors setting:

TEMPLATES = [
{
...
'OPTIONS': {
'context_processors': [
...
'preferences.context_processors.preferences_context_processor',
],
},
},
]

Usage
To create preferences for your app, create a Django model with the model inheriting from preferences.models.Preferences.
from django.db import models
from preferences.models import Preferences

class SitePreferences(Preferences):
logged_in_user_can_view = models.BooleanField(default=False)

You can then access these preferences in views or other modules by importing the preferences module. The preferences are exposed under preferences.<Model_Name>.<Preference_Name>
from preferences import preferences

logged_in_user_can_view = preferences.SitePreferences.logged_in_user_can_view

To manage the preferences in the Admin panel (which is the whole point of installing this package!!), register them in your app's admin.py:
from django.contrib import admin
from preferences.admin import PreferencesAdmin
from <App_Name>.models import SitePreferences

admin.site.register(SitePreferences, PreferencesAdmin)

Finally, if you've added the context processor in step 3 of the usage section, then you can access your preferences in the template by typing:
{{ preferences.SitePreferences.logged_in_user_can_view }}
