python - How do I use beaker caching in Pyramid? -

i have following in ini file:

cache.regions = default_term, second, short_term, long_term cache.type = memory cache.second.expire = 1 cache.short_term.expire = 60 cache.default_term.expire = 300 cache.long_term.expire = 3600 

and in __init__.py:

from pyramid_beaker import set_cache_regions_from_settings set_cache_regions_from_settings(settings) 

however, i'm not sure how perform actual caching in views/handlers. there decorator available? figured there in response api cache_control available - instructs user cache data. not cache server-side.

any ideas?

my mistake call decorator function @cache_region on view-callable. got no error reports there no actual caching. so, in views.py trying like:

@cache_region('long_term') def photos_view(request):     #just example of costly call google picasa     gd_client = gdata.photos.service.photosservice()     photos = gd_client.getfeed('...')     return {         'photos': photos.entry     } 

no errors , no caching. view-callable start require parameter! works:

#make separate function , cache @cache_region('long_term') def get_photos():     gd_client = gdata.photos.service.photosservice()     photos = gd_client.getfeed('...')     return photos.entry 

and in view-callable just:

def photos_view(request):     return {         'photos': get_photos()     } 

the same way works @cache.cache etc.

summary: do not try cache view-callables.

ps. still have slight suspiction view callables can cached :)

upd.: hlv later explains, when cache view-callabe, cache never hit, because @cache_region uses callable's request param cache id. , request unique every request.
