Does it run with the devserver? Are you sure you are using the same
versions of django and/or python on both machines. If not, it could be
some syntax differences etc. I would check that first.
Then, try Joseph's suggestions anyway. As he says it will "maybe give
you an idea of where to focus."

Thanks. I think I figured it out. It's not the expr tag, it's {%%}. It
seems that {%%} doesn't cause a form field to render into HTML the way
{{}} does.

Hi Sanjay,
reasons are probably simplicity of code and that it's easy to circumvent when
you start with your own fresh database.
Django is more targeted to this case, not for legacy systems. Having said this,
I use Django for a really ugly old existing database, and it works. There are

Hello everyone,
A (long) question:
I have two models, linked by a single key. LinkClass ("search engines",
...) and Link ("http://www.google.com";, "http://www.yahoo.com";)
Now, in Python I can do:
for link_class in LinkClass.objects.all():
print link_class.name
for link in link_c

I have been using Django for about a month now and I just moved over to
the development version.
I am creating an application in which the client has dictated very
stringent database record management in order to have a detailed audit
trail on all changes made data. This does not necessarily mean
It would be very nice to draw a class diagram and get the model code
generated for Django. Any tool supporting this? There are some open
source tools like argouml and andromda who do this for some ORMs.
Reference to any supporting tools, or any kind of inputs on this will
help a lot.
Thanks

Hi All,
We are working on a service provisioning workflow interface using Django 0.91.
We wrote some views that are being used to create/modify/delete
manager/subordinates relationships with or without inheritance
(Manager can also manage a subordinate's subordinates). We can also
visualize the
Thanks a lot for so quick and to the point replies. A few more
questions now hit me:
1. Are there any plans in future for supporting composite natural keys?
What is the reason behind not supporting this?
2. Is it so that using surrogate primary keys (system generated id) is
a better way compared
Is there some reason why I cannot have an AutoField(primary_key=False)
in my model? (In fact, documentation hints that I could, but manage.py
gives an assertion error from it.)
My pk is a charfield but I would also need an automatically
incrementing integer in the same class. Any ideas?

No, it doesn't. Seems this question should go into the FAQ ;-)
