class scott_test1(models.Model):

graphic_id = models.IntegerField()
graphic_desc = models.CharField(max_length=30)
curves = models.TextField()
graphic_type = models.CharField(max_length=4)
df = models.DateField(null=True, auto_now = True) # datetime.date
dtf = models.DateTimeField(null=True, auto_now = True) # datetime.datetime
tf = models.TimeField(null=True, auto_now =True) # datetime.time

foo=scott_test1(graphic_id=2,graphic_desc="here is some text", curves= ", ".join([str(x * 3.1514) for x in xrange(1000)]), graphic_type="none")

foo.save()

According to the docs at ​http://docs.djangoproject.com/en/dev/ref/models/fields/#datefield, foo.df should be a datetime.date object, not datetime.datetime:

In [7]: foo.df
Out[7]: datetime.datetime(2010, 11, 5, 10, 13, 3, 744903)

In [8]: foo.dtf
Out[8]: datetime.datetime(2010, 11, 5, 10, 13, 3, 745076)

In [9]: foo.tf
Out[9]: datetime.time(10, 13, 3, 745130)
