29904	Not Null CharField Doesn't generate DB constraint on Oracle	Vackar Afzal	nobody	"Given the following model:



{{{
class User(models.Model):
    myField1 = models.CharField(max_length=20)
    myField2 = models.CharField(max_length=20, blank=True)
    myField3 = models.CharField(max_length=20, null=True, blank=True)
}}}

I would expect myField1 and field2 to have a db constraint assigned to ensure that they are not null.
However all columns are nullable upon inspection via 3rd party db tool. 
Is this by design, or a genuine bug?
