[Django]関数ごとmemcacheに入れるための便利関数

こんな感じ。

def cache_func(key, timeout, func, *args, **kwargs):
    # get the result from memcache
    result = memcache.get(key)
    if result:
        return result
    # get the result from orginal function
    result = func(*args, **kwargs)
    # set the result to memcache
    memcache.set(key, result, timeout)
    return result

使い方はこんな感じ。

def get_hogehoge(id, count):
    return "%(id)s_%(count)s"
cache_timelines = lambda id, count: cache_func('cachekey_%(id)s_%(count)s' % dict(id=id, count=count), 60 * 10, get_hogehoge, id, count)
