Christ, I totally messed up this post. I did not mean "python

You do not need to run syncdb before creating your first app, syncdb search
for the apps in INSTALLED_APPS and sync their models with the database, so
you can run it anytime. Note that if you just change an existing model
syncdb won't sync anything, you'll need migrations for that.

if the second line works for you (i.e. does not raise

definition.

Yes, it does work in runserver, as might be expected since runserver
uses exact same environment as the shell.

You could pass the values from the view to the template and use javascript

In your Customer model there are fields which cannot be Null, so you cannot
instance.save() before setting those properties. So, you may have to check
for the category field in your loop and if it is category, save the
instance first. Something like the following:

Hi Alain,
Glad that it worked out! :-)
To clarify, a blank is different from a Null, or "None" in Python/Django. A
blank character field is "" where a null character field is NULL. If a
field does not specify null=True, and you try to save an instance of that
object without specifying that field,

Sort of. With this code:

Can you try this and tell us what you see:
Run a shell using python manage.py shell

This will tell us whether or not the database, reference, and such are
correctly translating into a query. The error means
