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](http://docs.djangoproject.com/en/dev//topics/cache/#the-per-view-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: 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".
