As noted before in this thread I have a lazy rowgetter that only
triggers an exception
in the template. In other words, the except clause in my view isn't
triggered.
try:
rota = self.model.xmlapi_get_location (**kwargs)
except DBException, e:
code, message = [epart.strip() for epart in e.msg.split(':')]
return HttpResponse(message, status=code,
content_type="text/plain")

I'm simply trying to trigger the exception handler in ipdb and that is
not happening
using either either the standard middleware or
decorator_from_middleware
methodologies. I guess this might be because control has passed from
the view?
decorators.py:handle_uncaught_exception _is_ called, but I am unable
to interject my
ExceptCatcher with it.

Sorry if this is the wrong place to post. However there are a number
of people on the
web reporting that they are unable to trigger process_exception. Hence
my query here.
