Hi,
I am currently stuck with an issue that I can't fix. I've just
upgraded my app to Python 2.7 using Django Nonrel. I've tried posting
this question to that group but did not get any response. So any help
would be greatly appreciated.
This is what I am getting when I try to perform a defer function in
the production environment:
Error: Server Error
The server encountered an error and could not complete your request.
If the problem persists, please report your problem and mention this
error message and the query that caused it.
In the log this is what it shows:
Traceback (most recent call last):
File "/base/python27_runtime/python27_lib/versions/1/google/
appengine/runtime/wsgi.py", line 174, in Handle
result = handler(self._environ, self._StartResponse)
TypeError: 'module' object is not callable
The code that is currently causing the problem:
def _update_profile_image_url(user, new_url = None):
from communication.message.models import PrivateMessagePool
for entity in
PrivateMessagePool.objects.filter(sender=user).all():
entity.sender_image_url = new_url
entity.save()
#Update profile images when it's required
from google.appengine.ext import deferred
try:
queue_name = 'default'
deferred.defer(_update_profile_image_url, self.user,
new_url=self.image_url, _queue=queue_name)
except Exception, e:
logging.error('caught%s in image upload deferred section', e)
raise e
Everything works in the development environment under the localhost.
However, when I deploy it to production, it crashes every single
time. I've tried to comment out the deferred.defer line in production
and everything works again. So it has to be the background task that
is causing the problem. But there is no way for me to pinpoint what
is failing since I didn't get any error messages in development and
everything works smoothly. Please help if you know what I did wrong.
Thanks in advance!
