Python Accessing Caller **locals() from callee method using sys._getframe

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

notice getCallerInfo

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')
