Django中字段选择的“人类可读”值

Question

PAYCODE_BLUEPAY = "BLUEPAY"
PAYCODE_HEARTLAND = "HEARTLAND"
PAYCODE_1STPAY = "1STPAYMENT"
PAYCODE_CHOICES =(
    (PAYCODE_1STPAY, '1St Payment'),
    (PAYCODE_BLUEPAY, 'Bluepay Payment'),
    (PAYCODE_HEARTLAND, 'HeartLand Payment'),

)

class Payment(models.Model):
    paymentmethod = models.CharField("Payment Method", max_length=20, choices = PAYCODE_CHOICES, blank=False, null=False)

    def __str__(self):
        return self.paymentmethod 

方法__str__(self)将返回BLUEPAY或HEARTLAND或1STPAYMENT。但我希望__str__(self)返回第一笔付款， Bluepay付款或 HeartLand付款。

请给我解决方案。感谢。
