Hi,
I am building a new site in Django 1.4 and I'm using the South migration
tool to keep my dev MySQL database in sync with changes made to my models.
It should be said that I use one MySQL database account to serve various
Django projects/apps (confusing, yes). It all seems to be working fine
until I attempt to open up the Admin site from the project currently in
development (bus/certs/admin/).
It *appears* that the autodiscover is trying to find a model "Listing" that
is no longer in existence, but did exist in earlier development stages. I
deleted that model and have since run a South migration to extend that
deletion to the database. That seems to have worked fine. What did not
seem to happen is the removal of references to the "listing" table in the
django_content_type and auth_permission tables, so I removed those manually
thinking the autodiscover might be "seeing" those entries and subsequently
attempting to find the model in "bus_models.models". That seems to have
made no difference, the error still exists.
Not sure if this matters or not, but I had initially used the admin up in a
separate project ("deans" vs. "certs") and it still works. It even still
lists the "Bus_models.Listing" model and only fails once I click on that
link...gives me a "Table does not exist" error, as I would expect. This
does make me think, however, that there is a lingering pointer somewhere
that I'm unable to locate.
I can reliably cause this error to occur and go away again by
uncommenting/commenting the following lines in my
bus(app)/certs(proj)/urls.py file:
from django.contrib import admin
admin.autodiscover()
(r'^apps/bus/certs/admin/', include(admin.site.urls)),
Here is the traceback of the error page that shows up when the above are
uncommented (no matter what url I use):

Lastly, I have searched in as many ways I can think to search for any
reference to "Listing" in the database and code base, but cannot find
anything.
Any help would be greatly appreciated.
