[ #26 ] Tag Clouds and Caching Permalink
On the right you will notice a new tag cloud. I wrote a tag_cloud templatetag in Django for it. Generating a tag cloud involves a little calculation, so I cached it using Django 1.0's Template Fragment Caching. It lets me wrap anything in a template with a cache templatetag, specifying seconds to cache for.
I have two separate cache settings, one for dev and one for prod environments (in their corresponding settings files.) They are using Django's filesystem caching - so the cache is just stored on disk. I am storing the cache in a subdirectory of the codebase, but I don't want the cache being carried around in the Git repo, so I added:
/cache/*
... to my .gitignore file in the codebase root. Nice!
