So, I finally tried installing version 1.3.4 of the SDK, which was a
bit of a headache, because my dev site would not start up after I did
this. I think this is due to
https://code.google.com/p/google-app-engine-django/issues/detail?id=161
. To work around the issue, I added ipaddr supplied with the SDK to my
PYTHONPATH. I'm able to start my site now, but my original issue
(TemplateDoesNotExist) hasn't stopped happening. Another symptom of
the problem is different uncaught TemplateDoesNotExist exception with
the following message:
Your TEMPLATE_DIRS setting is empty. Change it to point to at least
one template directory.
This doesn't make sense, because my settings.py includes the
following:
TEMPLATE_DIRS = (
os.path.join(ROOT_PATH, 'templates')
)
This is why I believe TEMPLATE_DIRS is being cleared at some point,
something that I would never do in my app code. Another observation
that supports this theory is that the problem generally goes away when
I restart my server (I might have mentioned this before).
I'm going to try working around this by using the svn version of
google-app-engine-django (r105), but I haven't been able to use it it
for long, so I'm not sure if it'll make the problem go away.
grr...
