This seems very basic and I must be missing something, but here goes anyways...

With two models like so:

class School(models.Model):
    name    = models.CharField("Official School Name", max_length=128)
    address = models.TextField("Address of the School", max_length=256)
    mascot  = models.CharField("Name of the School Mascot", max_length=128)

class StudentProfile(models.Model):
    name   = models.CharField(max_length=128)
    school = models.ForeignKey(School)

If the student gets created before the school, how do I give 'school' a default empty value? Is it blank or null or what?

Thanks!
