[Tutor] Accessing callers context from callee method

[mobiledreamers at gmail.com]

i found the solution
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'<http://www.devx.com/opensource/Article/31593/1954%27>
''
    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')
