Django choices. How to set default option?

Question

How to set default STATUSES option ?

class Order(models.Model):     STATUSES = (         (u'E', u'Expected'),         (u'S', u'Sent'),         (u'F', u'Finished'),     )      status = models.CharField(max_length=2, null=True, choices=STATUSES) 

Answer 1

status = models.CharField(max_length=2, null=True, choices=STATUSES, default='E') 

or to avoid setting an invalid default if STATUSES changes:

status = models.CharField(max_length=2, null=True, choices=STATUSES, default=STATUSES[0][0])
