Some cache problems

Question

1. I'm wondering if I can delete a cached content made in template cache. I want to delete it from my view. I have in my template {% cache 500 cache_name sites.number %} Is it possible to delete all "cache_name" cached content within the view, for example when some action is made?

2. I want to use per-vie cache. I do all what is described, but when I call: @cache_page(3600, cache="cache_name") I get error:

Exception Type: ValueError Exception Value: need more than 1 value to unpack

(Below is the traceback)

What I want to achieve is to cache all my template block or view and have a possibility to delete all cache connected with it when some actions are made. Pagination is included

Answer 1

http://docs.djangoproject.com/en/1.2/topics/cache/

The cache middleware caches every page that doesn't have GET or POST parameters.

Answer 2

What version of Django are you using? The parameter "cache" is only available in the development version. If you're using Django 1.2, you can only use "key_prefix".
