Overview
--------
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.
Installation
------------
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.
Register that class with the Admin site, using the ``ConfigurationAdminModel``::
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.

-------------

~~~~~~~~~~~~~~~~~~~~
* 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/edx/edx-django-utils/tree/master/edx_django_utils/cache#tieredcachemiddleware>`_

the default Django cache.
