如何设置默认的STATUSES选项？

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)

1 个解决方案

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

或者，如果STATUSES发生变化，则避免设置无效的默认值：

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