This is my first attempt at memcaching html page using cheetah
since cheetah render needs locals() i use getCallerInfo() to get the
locals() and send to memcached
let me know if it is possible to better do this
*
*
*utils.py*
@log_time_func
def renderpage(key, htmlfile, deleteafter=3600):
from globaldb import mc
try:page = mc.get(key)
except:
page=None
clogger.info('except error mc.get '+ key)
if not page:
clogger.info(key+ ' rendering cheetah page')
terms = getCallerInfo(1)
#print terms
page = str(web.render(htmlfile, asTemplate=True, terms=terms))
try:mc.set(key, page, deleteafter)
except:
clogger.info('except error mc.set '+ key)
return page
@log_time_func
@memcachethis
def mcrenderpage(key, htmlfile, deleteafter=3600):
terms = getCallerInfo(2)
#print terms
return str(web.render(htmlfile, asTemplate=True, terms=terms))
def getCallerInfo(decorators=0):
'''returns locals of caller using frame.optional pass number of
decorators\nFrom Dig deep into python internals
http://www.devx.com/opensource/Article/31593/1954'''
f = sys._getframe(2+decorators)
args = inspect.getargvalues(f)
return args[3]
*Usage*
key=facebookstuff.APP_NAME+'newstart'+str(uid)
return utils.renderpage(key, 'pick.html')
