Hi Nathanael,
inspectdb on Oracle will only find tables in the Django user's
schema. It doesn't inspect views or synonyms or tables in other
schemas. I would guess that one of these describes you
idation.
I'll make a note of this. At the very least, there should be a more
descriptive error message for when this comes up.

I've run into the following error in a SQL DB envornment and was
wondering if any one else had run into problems with Deadlocking with
MySQL. What would be the proper way to handle this kind of error in
Django?
Do most folks simply catch the OperationalError and show some sort of
error to the use
ink we can just catch it and return an error to the user.
I'm curious what you did to catch the error and retry. Did you create
a custom kind of DB backend? or did you just add that logic to the
particular view that was giving you trouble?

Pass the form class to modelformset_factory() in the form argument.
The factory will then use the AuthorForm class as the base form class
when it creates the modelform class for the formset.
modelFormset = modelformset_factory(Author, form=AuthorForm)

validators is a module that was added in Django 1.2.
You probably have the wrong version of Django installed or are using
Django 1.1 with a django application that requires Django 1.2.

If you don't need the name, surname etc. then don't use them. They are
optional fields. You can also implement a custom form or view when the
user registers that can make sure the email has not been previously
registered.
If you need to add additional fields then you should create a custom
profile

Instead of using annotate, could you just add the avg_days_instock
field as another key in the select argument to extra?

Would that get you the group by and average field you were looking for?
If not it might be easier to just write what you want as custom SQL.
