Cache

from decorated.decorators.cache import SimpleCache

cache = SimpleCache()

@cache.cache('/config/{key}')
def get_config_from_db(key):
    print('loading config from db ...')
    return 'config'

@cache.uncache('/config/{key}')
def flush_config(key):
    print('flushing config')

get_config_from_db('config1')
flush_config('config1')

This will cache the result with the key "/config/{key}" where "{key}" is the actual value of the key parameter.

The code below implements the same function:

from decorated.decorators.cache import SimpleCache

cache = SimpleCache()
config_cache = cache.cache('/config/{key}')

@config_cache
def get_config_from_db(key):
    print('loading config from db ...')
    return 'config'

@config_cache.invalidate
def flush_config(key):
    print('flushing config')

get_config_from_db('config1')
flush_config('config1')

If you have pylru installed, you may replace SimpleCache with LruCache. You may also derive your own class from decorated.decorators.cache.Cache for memcached, redis, etc.
