The Django admin changelist rows are not contained within a block that could be extended through standard template caching with tags. Also, the generation of the cache key for more complex objects might be too complicated to do in the templates. Plus there might be out-of-process changes (e.g.: one of manual data fixes) that don’t change the cache key, but should invalidate the cached row.

Hence the existence of this application - declaratively cache your admin rows!

Setup

• install it via pip install django-admin-caching

• add it to your settings and it auto-registers itself

  settings.INSTALLED_APPS = [
     ...
     'django_admin_caching',
     ...
  ]

• configure the admins you want cached (see below for detail)

Configuring the admin

• to enable cahcing, the admin_caching_enabled attribute of the model’s admin class must be set to True. Note this means you might need to unregister the default admin and register your custom one for third party models (e.g.: django.contrib.auth.models.Group)

• the cache key by default is <admin class module name>.<admin class name>- <model class app label>.<model class name>-<model object pk>. This could be customized by adding a custom key method to the admin class that returns the string key for the model object part of the key - def admin_caching_key(self, obj)

  • if settings.USE_I18N (and settings.USE_L10N) are enabled, for each enabled setting, a prefix will be added to the above, e.g.: <language name>.<locale name>.<the key from above>

• on the admin level, the cache’s name can be specified through the admin_caching_cache_name attribute. If omitted, it defaults to default

• on the admin level, the cache’s timeout can be specified through the admin_caching_timeout_seconds attribute. If omitted, it defaults to the cache’s default_tiemout

Release Notes

• 0.1.2

  • if i18n/l10n is enabled, account for it in the cache prefix

• 0.1.1

  • allow specifying the cache timeout on the admin class

• 0.1.0 - initial release

  • supports Django 1.8, 1.9, 1.10 on python 2.7, 3.3, 3.4, and 3.5

  • supports the following configuration attributes on the admin class

    • admin_caching_enabled

    • admin_caching_cache_name

    • admin_caching_key for custom object cache key
