I had the same problem last month.
Digging around the source code of pylons.decorators.cache.py,
There is a method called 'create_cache_key' that you can call to invalidate
directly.
Below is how I invalidate beaker_cache:
from pylons import cache, request
from pylons.decorators.cache import create_cache_key
class CacheHandler(object):
@classmethod
def expire_controller_cache(cls, func):
'''
Usage: CacheHandler.expire_controller_cache(getattr(controller_instance,
action_name))
'''
key_dict = request.GET.mixed()
namespace, key = create_cache_key(func, key_dict)
cache.get_cache(namespace).remove(key)
# Example Controller
class SomeController(BaseController):
def index(self):
pass
# How to use it
some_controller = SomeController()
CacheHandler.expire_controller_cache(getattr(some_controller, 'index'))
