I was trying to use Bottlenose's API (thin wrapper on the Amazon Products
API), alongwith web2py's Cache.
bottlenose: https://github.com/lionheart/bottlenose
Bottlenose provides callbacks where the caching logic can be introduced.
The code is listed below
cache_disk = CacheOnDisk(folder='path...')
cache_ram = CacheInRam()
def write_query_to_db(cache_url, data):
return cache_ram(cache_url, lambda: cache_disk(cache_url, lambda: data,
3600), 60)
# Return None if the key is not present
def read_query_from_db(cache_url):
# How do I read from the cache, the following doesn't seem to work
return cache_ram(cache_url, lambda: cache_disk(cache_url))
amazon = bottlenose.Amazon(CacheWriter=write_query_to_db,
CacheReader=read_query_from_db, ...)
Any suggestions?
Thanks,
Kiran
