Hi Doug,
This is probably happening because the function you're trying to
defer is defined in the request handler. Move the function you want
to defer to another module (a different python file) and import it
from there.
This limitation is mentioned in the deferred article (see the
limitations section).

I am having some problems with the deferred.py. When I try to run a
stand-alone function (i.e. not a class method) such as:
from google.appengine.ext import deferred
def easything(n):
print easy %s % n
for thing in longlist:
deferred.defer(easything, thing)
I get this in the log:
File C:\Program Files\Google\google_appengine\google\appengine\ext
\deferred\deferred.py, line 129, in run
raise PermanentTaskFailure(e)
PermanentTaskFailure: 'module' object has no attribute 'easything'
After reading through the documentation again and again I noticed this
in the documentation
http://code.google.com/appengine/articles/deferred.html
from google.appengine.ext import deferred
def do_something_expensive(a, b, c=None):
logging.info(Doing something expensive!)
# Do your work here
# Somewhere else
deferred.defer(do_something_expensive, Hello, world!, 42, c=True)
Is the function do_something_expensive supposed to be indented? I
guess what I am getting at is can I feed stand alone functions into
deferred.defer or do you have to only use methods (which would explain
the indentation - I guess). . To add more color to this question I
posted this on stackoverflow last night:
http://stackoverflow.com/questions/6225400/problem-posting-to-datastore-with-deferred-defer-tasks
I have found the error in the log since then, and have noticed that no
matter how simple I make the function I am getting this error. I am
not importing anything fancy.
Thanks for any help I am new to programming in general.
