I'll guess that you see this each time a new process starts on the web server and it tries to import that view as part of processing the URL Conf. It's one of the more confusing/annoying Django error handling cases and "real soon now" we'll fix it (I keep poking at it and finding more and more edge cases). Once the import has failed once, you won't see it again for that process, since it won't try to be imported again. You might well have more consistent luck debugging the problem using the development server, since that's easier to stop and restart and force a reload of everything. Try a few experiments from the shell prompt. Try to import that view file. Try to manually do some calls to django.core.urlresolvers.reverse() -- which will have the effect of importing all of your views -- and see if that triggers the problem. If that fails, try reducing your problem code to the smallest possible example. Comment out all the views and imports except for that one particular view and a single URL pattern that refers to it and such that the problem still occurs. That will help narrow down where the problem occurs. > Could it be that there are too many > ForeignKey relationships. i.e. the Buyer model is used in 3 other > models. There's not really any justification for that guess. Python and Django don't just "get tired." and three of anything would be a very low limit. :-) Regards, Malcolm --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
