Can I get expiration time of specified key in django cache?
cache._expire_info.get('foo')
to get the unix timestamp
RedisCache has ttl
:
cache.ttl('foo:bar:2020-09-01')
to get the unix timestamp:
cache_expire_time = datetime.datetime.fromtimestamp(
[value for key, value in cache._expire_info.items() if 'devices' in key.lower()][0]
) - datetime.datetime.now()
to get the remaining time in seconds:
cache_expire_time.seconds
Note that it looks like this only works for locmem, not memcached, if someone knows how to do this in memcached please comment
