=============================== django-cache-manager

Simple cache manager for django models that caches querysets for a model. Cache manager will cache any query that has been seen for a model. Model cache is evicted for any updates/deletes to the model. This manager is useful for models that don't change often.

Installation

pip install django-cache-manager

Caching strategy

• Cache results for a model on load.
• Evict cache for model on update.

Usage

Add to installed apps

INSTALLED_APPS = (
    ...

CACHES = {
    'django_cache_manager.cache_backend': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '127.0.0.1:11211',
    }
}

   #set cache manager as default
   objects = CacheManager()
