django-clear-cache

I often find myself in situations where I need to fully clear my website's cache (memcached or whatever). Often times this is required because:

• I'm deploying new code and it will fail to run properly with my currently cached objects.
• I need to purge invalid (or old) information.
• A million other reasons.

The standard way to clear your cache is to open up a management shell, eg:

$ python manage.py shell
Python 2.7.3 (default, Apr 20 2012, 22:39:59) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.core.cache import cache
>>> cache.clear()

But obviously, this is annoying as I have to manually log into my production shell.

django-clear-cache makes this process as easy as running a single management command.

Install

To install django-clear-cache, simply run pip install django-clear-cache and you'll get the latest version installed automatically.

Next, modify your Django settings.py file, and add clear_cache to your INSTALLED_APPS setting:

INSTALLED_APPS = (
    # ...
    'clear_cache',
)

Usage

To clear your cache, simply run the clear_cache management command:

$ python manage.py clear_cache
Your cache has been cleared!

NOTE: This will only (obviously) work if you've got a cache configured (eg: memcached, local memory, etc.). If you have no idea what I'm talking about, read through the official Django caching docs.
