In this class I have a method which I cache its result using cachetools:
from cachetools import cached, TTLCache class Log: @cached(TTLCache(maxsize=200, ttl=300)) def get_sessions(self, user_id): query = """select * from comprehensive_log.sessions where user_id = %s order by start DESC limit 50""" user_sessions = self.fetch_data_from_log(query, (user_id,)) return user_sessions def get_last_session(self, user_id_arg): user_sessions = self.get_sessions(user_id_arg) ... I call this class in this file sessions.py:
from src.OO_log import Log log_object = Log() def get_data(): user_list = get_user_list_from_database() for user in user_list: log_object.get_last_session(user.id) return True ... Now I use get_data method of sessions.py in my main.py:
from sessions import get_data() while the_end: result = get_data() # How can I clear cache here before going for the next loop? I want to clear the cache after the end of each while loop.
What have I tried?
I tried changing the Log class __init__ like this:
class Log: def __init__(self): self.get_sessions = cached(TTLCache(maxsize=200, ttl=300))(self.get_sessions) def get_sessions(self, user_id): query = """select * from comprehensive_log.sessions where user_id = %s order by start DESC limit 50""" user_sessions = self.fetch_data_from_log(query, (user_id,)) return user_sessions and deleting result in while loop:
while the_end: result = get_data() del result But none of them helped.
So how can I clear python cachetools manually or is there anything else I can do to overcome this problem?
