Hm, that's not appropriate to prove that the re-use never happens.

I'm pretty sure that OID is not reused. It's database behavior to control

Hi Lisa,
The easiest way (I have found) to get the admin media in to your
project is to create a symbolic link inside your static media folder
to the admin/media subfolders. I believe there are three of them

If the field isn't a required field, I don't think South would complain about

What type of field is it? What version of Django, and what version of South?

I do have an DB with 300K rows and something as 6 tables.

2) Import all data on Django? s

In my Django-app where I want to create a cache, I don't have a request

I don't need to access that cache in the templates anywhere. I would like

What are you trying to accomplish? If you set blank = True and null = True then
they'll be null in the database after the migration and if left blank by the
user.

When you say "the problem happens when I select 2010-10-10 in the

2010-10-09 is set in the field." What do you exactly mean? It looks
like you need to revisit your app/models.py.

I had the same problem (and so did others as I found out). As far as I
