django-setty

Django-Setty allows you to dynamically change settings inside the Django Admin Console. The app provides both a database and a cache backend for storing and retrieving your settings.

Requirements

• Python 3.6+
• Django 2.0+

Continuous integration currently tests Django >= v2.

Installation

pip install django-setty

Django Configuration

Add setty to the list of INSTALLED_APPS in your Django settings:

INSTALLED_APPS = [
    ...
    'setty'
]

Create the Setty database table by running

python manage.py migrate

Specify the backend to use using the SETTY_BACKEND setting. The valid backend values are 'DatabaseBackend' and 'CacheBackend'.

'DatabaseBackend' always accesses the database when retrieving settings.

'CacheBackend' only accesses the database if the item is not in the cache, and caches the value once retrieved.

Define the length of time settings should be cached for using the SETTY_CACHE_TTL setting. The default cache TTL is one hour.

SETTY_BACKEND = 'CacheBackend'
SETTY_CACHE_TTL = 60  # 60 seconds

Usage Examples

Open the Django admin console at /admin and open Setty Settings. Here, you will see the list of all settings defined in Setty.

To add a new setting, click the add button.

Enter the setting name, type (String, Integer, Float, Boolean, List, Dictionary) and the value. Note, the List and Dict data type expect the data to be in the JSON format e.g. {"a": 1, "b": 2} and [1, 2, 3].

Once settings have been created, you will be able to access these in your code.

from setty import config

assert config.my_integer == 10

If the setting does not exist in the database, the value defined in the setting SETTY_NOT_FOUND_VALUE will be used. If this is not set, None will be returned.

Setty can be used inside Django templates by adding 'setty.context_processors.setty_settings' to the TEMPLATE_CONTEXT_PROCESSORS setting and accessing it via the setty key.

The value of a setting can also be updated by using the syntax:

from setty import config

config.my_integer = 100

Note: Only settings that already exist in the database can be updated. New settings cannot be added this way.

Loading all settings into the Cache

If you use the CacheBackend backend, you can easily load all settings into the Cache. This is useful if you want to cache all settings when you start up your app.

from setty.backend import CacheBackend
CacheBackend().load_all_settings_into_cache()
