This app allows other apps to easily define a configuration model that can be hooked into the admin site to allow configuration management with auditing.

Getting Started

Add config_models to your INSTALLED_APPS list.

Usage

Create a subclass of ConfigurationModel, with fields for each value that needs to be configured::

class MyConfiguration(ConfigurationModel):
    frobble_timeout = IntField(default=10)
    frazzle_target = TextField(defalut="debug")

This is a normal django model, so it must be synced and migrated as usual.

The default values for the fields in the ConfigurationModel will be used if no configuration has yet been created.

from django.contrib import admin

from config_models.admin import ConfigurationModelAdmin

admin.site.register(MyConfiguration, ConfigurationModelAdmin)

Use the configuration in your code::

def my_view(self, request):
    config = MyConfiguration.current()
    fire_the_missiles(config.frazzle_target, timeout=config.frobble_timeout)

Use the admin site to add new configuration entries. The most recently created entry is considered to be current.

Configuration

The current ConfigurationModel will be cached in the configuration django cache, or in the default cache if configuration doesn't exist. The configuration and default caches are specified in the django CACHES setting. The caching can be per-process, per-machine, per-cluster, or some other strategy, depending on the cache configuration.

You can specify the cache timeout in each ConfigurationModel by setting the cache_timeout property.

You can change the name of the cache key used by the ConfigurationModel by overriding the cache_key_name function.

Extension

ConfigurationModels are just django models, so they can be extended with new fields and migrated as usual. Newly added fields must have default values and should be nullable, so that rollbacks to old versions of configuration work correctly.

[2.0.0] - 2020-02-06

Dropping support for Python 2.7
Switch to using edx-django-utils TieredCache (a two-layer cache that uses both Django's cache and an internal request-level cache) to reduce the number of memcached roundtrips. This was a major performance issue that accounted for 10-20% of transaction time for certain courseware views in edx-platform.
It is now REQUIRED to add RequestCacheMiddleware to middleware <https://github.com/openedx/edx-django-utils/tree/master/edx_django_utils/cache#tieredcachemiddleware>_ to use ConfigModels.
Remove usage of the "configuration" cache setting. ConfigModels now always use the default Django cache.
Django Rest Framework 3.7 and 3.8 are no longer supported.
