I'm no expert but this is what I built to log all user actions -- warts
and all
def decorate(func):
##################print 'Decorating %s...' % func.__name__
def wrapped( *args, **kwargs):
request = args[0]
if len(args)>1: command=str(args[1])
else: command = ''
ipaddr = request.META['REMOTE_ADDR']
user = request.session.get('user', None)
if user: userid = user.userid
else: userid = '?'
qs = extract_querystring_from_request(request)
parameters = Parameters(**qs)
resid = parameters.pop('resid', '')
assessmentid = parameters.pop('id', 0)
facility = parameters.pop('facility','')
modified = func.__name__ in ("setvalues", "setraw", "create",
'editcaas')
### print func.__name__, 'zzzzzzzzzzzzzzzzzzzzz', modified, qs
modified = modified or (func.__name__=='command' and
command!='print')
fieldnames = parameters.values().keys()
for signature in SIGNATURE_FIELDS:
if signature in fieldnames: command='signit'
if (not facility) and resid:
facility = resid[:2]
option = str(parameters)[:110]
action = '%s:%s' % (func.__name__, command)
### print "\n\n\n\ncalled wrapped function with ", (action,
option, str(parameters))
record = models.HipaaLog.objects.create(Version=K.VERSION,
userid=userid,
Action=action,
Options=option,
#StartTime =
datetime.datetime.now(),
AssessmentId=assessmentid, ResidentId=resid,
Modified = modified,
IpAddress = ipaddr,
Facility=facility)
#print record.Modified, record.Action, 'record'
results = func( *args, **kwargs)

return results

Subject: Sample Custom Decorator
Hey Guys,
Would anyone be willing to show me an example of a very simple and
dumb decorator for views? I've been trying to read the existing
decorators and play with a couple of snippets but I'm having a lot of
trouble with two aspects -- grabbing the User Instance and Redirecting
somewhere besides Login (without making it look like a hack).
Here's some ugly pseudo-code for what I'm trying to accomplish...
# Custom Decorator
def my_decorator(function = None)
# Grab Data
request = how_do_i_get_this?
user = request.user
# Perform Logic, Redirect or Continue Normally
if user.foo():
redirect to '/foo' URL
else
display requested view?
# Decorated TemplateView
url(r'^$', my_decorator(TemplateView.as_view(template_name =
'bar.html'))),
Thanks!
