Tracking a bad import

[goodwinb]

I am setting up a server and when I run manage.py syncdb I get the
error 'cannot import name pre_delete'. How can I get more trace
information about where the bad pre_delete is?

Python 2.6; Django 1.1-beta; using comments, markdown, statlib

Page not found (404)

Request Method:	GET
Request URL:	http://localhost:8080/main/

Using the URLconf defined in pollango.urls, Django tried these URL patterns, in this order:

1. ^$
2. ^create/$
3. ^poll/(?P<poll_key>[^\.^/]+)/$
4. ^poll/(?P<poll_key>[^\.^/]+)/results/$

The current URL, /main/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

Fixed it by reinstalling all of my packages.

Did you read the tutorial? None of your url regexes look anything
like /main/. And why did you hijack someone else's thread that was
about a completely different topic?

[Andrew Fong]

Ignoring thread hijacking there and responding to the OP.

The next time you have an import error, try using the -v option, like
this: python -v manage.py syncdb

That'll print every module being imported as it's being imported -- it
might help identify what's missing.

Alternatively, use pdb (http://docs.python.org/library/pdb.html)
