Not here:
mysql> show create table myapp_modela;
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table
|
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
| myapp_modela | CREATE TABLE `myapp_modela` (
`id` int(11) NOT NULL auto_increment,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 |
+--------------+----------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
mysql> insert into myapp_modela values (1);
Query OK, 1 row affected (0.00 sec)
mysql> select * from myapp_modela where id is NULL;
Empty set (0.00 sec)
Also, that doesn't explain why Django 0.96 does what I expected.
