I made a workaround to reset cache (per session for now).
I have array, where I mark keys to be reset, and afer reset they can
be removed or marked as done.
def caching_time_get(key, caching_time=60*60*24):
"""
function to handle caching resets
when the reset is on,
it returns 0 once -- so the cache should expire
and then it goes on standart expiries
"""
if key in session.cache_invalidate and
session.cache_invalidate[key]:
return 0
else:
return caching_time
then I do:
@cache( the_key, time_expire=caching_time_get( the_key ),
cache_model=cache.ram )
def some_controller():
return sth_time_greedy()
and if I need to refresh cached stuff, I do:
session.cache_invalidate[the_key]=True
