django-cachepurge Description

Django Middleware and utilities that send "PURGE" request to an upstream cache django-cachepurge allows Django to purge HTTP cache when a model instance is changed or deleted. It does this by sending "PURGE" requests to one or more upstream HTTP cache (such as Squid or Varnish). This is inspired by Plone CacheFu components.UsageIn settings.py put 'django_cachepurge' before any other application; else it may failt to register some models:INSTALLED_APPS = ( 'django_cachepurge', ...)Add the middleware:MIDDLEWARE_CLASSES = ( ... 'django_cachepurge.middleware.CachePurge',)Define CACHE_URLS:CACHE_URLS = 'http://127.0.0.1:3128'or if you have more than one cache:CACHE_URLS = ('http://127.0.0.1:3128', 'http://192.168.1.42:3128')ModelsUrls are extracted from models instances on post_save signal. Two sources are used:* instance.get_absolute_url(), if it exists* instance.get_purge_urls(), if it exists. The application expects a list of absolute paths similar to what is provided by get_absolute_url().Purge request is sent when response has been computed: if an exception occurs the urls are not purged. Purge requests are asynchronous: worker threads handle that so that we don't have wait to complete all requests before returning the response. Requirements: · Python · Django
